+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+
+A JavaScript library for arbitrary-precision decimal and non-decimal arithmetic.
+
+[![Build Status](https://travis-ci.org/MikeMcl/bignumber.js.svg)](https://travis-ci.org/MikeMcl/bignumber.js)
+
+<br />
+
+## Features
+
+  - Integers and decimals
+  - Simple API but full-featured
+  - Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal
+  - 8 KB minified and gzipped
+  - Replicates the `toExponential`, `toFixed`, `toPrecision` and `toString` methods of JavaScript's Number type
+  - Includes a `toFraction` and a correctly-rounded `squareRoot` method
+  - Supports cryptographically-secure pseudo-random number generation
+  - No dependencies
+  - Wide platform compatibility: uses JavaScript 1.5 (ECMAScript 3) features only
+  - Comprehensive [documentation](http://mikemcl.github.io/bignumber.js/) and test set
+
+![API](https://raw.githubusercontent.com/MikeMcl/bignumber.js/gh-pages/API.png)
+
+If a smaller and simpler library is required see [big.js](https://github.com/MikeMcl/big.js/).
+It's less than half the size but only works with decimal numbers and only has half the methods.
+It also does not allow `NaN` or `Infinity`, or have the configuration options of this library.
+
+See also [decimal.js](https://github.com/MikeMcl/decimal.js/), which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.
+
+## Load
+
+The library is the single JavaScript file *bignumber.js* (or minified, *bignumber.min.js*).
+
+Browser:
+
+```html
+<script src='path/to/bignumber.js'></script>
+```
+
+[Node.js](http://nodejs.org):
+
+```bash
+$ npm install bignumber.js
+```
+
+```javascript
+const BigNumber = require('bignumber.js');
+```
+
+ES6 module:
+
+```javascript
+import BigNumber from "./bignumber.mjs"
+```
+
+AMD loader libraries such as [requireJS](http://requirejs.org/):
+
+```javascript
+require(['bignumber'], function(BigNumber) {
+    // Use BigNumber here in local scope. No global BigNumber.
+});
+```
+
+## Use
+
+The library exports a single constructor function, [`BigNumber`](http://mikemcl.github.io/bignumber.js/#bignumber), which accepts a value of type Number, String or BigNumber,
+
+```javascript
+let x = new BigNumber(123.4567);
+let y = BigNumber('123456.7e-3');
+let z = new BigNumber(x);
+x.isEqualTo(y) && y.isEqualTo(z) && x.isEqualTo(z);      // true
+```
+
+To get the string value of a BigNumber use [`toString()`](http://mikemcl.github.io/bignumber.js/#toS) or [`toFixed()`](http://mikemcl.github.io/bignumber.js/#toFix). Using `toFixed()` prevents exponential notation being returned, no matter how large or small the value.
+
+```javascript
+let x = new BigNumber('1111222233334444555566');
+x.toString();                       // "1.111222233334444555566e+21"
+x.toFixed();                        // "1111222233334444555566"
+```
+
+If the limited precision of Number values is not well understood, it is recommended to create BigNumbers from String values rather than Number values to avoid a potential loss of precision.
+
+*In all further examples below, `let`, semicolons and `toString` calls are not shown. If a commented-out value is in quotes it means `toString` has been called on the preceding expression.*
+
+```javascript
+// Precision loss from using numeric literals with more than 15 significant digits.
+new BigNumber(1.0000000000000001)         // '1'
+new BigNumber(88259496234518.57)          // '88259496234518.56'
+new BigNumber(99999999999999999999)       // '100000000000000000000'
+
+// Precision loss from using numeric literals outside the range of Number values.
+new BigNumber(2e+308)                     // 'Infinity'
+new BigNumber(1e-324)                     // '0'
+
+// Precision loss from the unexpected result of arithmetic with Number values.
+new BigNumber(0.7 + 0.1)                  // '0.7999999999999999'
+```
+
+When creating a BigNumber from a Number, note that a BigNumber is created from a Number's decimal `toString()` value not from its underlying binary value. If the latter is required, then pass the Number's `toString(2)` value and specify base 2.
+
+```javascript
+new BigNumber(Number.MAX_VALUE.toString(2), 2)
+```
+
+BigNumbers can be created from values in bases from 2 to 36. See [`ALPHABET`](http://mikemcl.github.io/bignumber.js/#alphabet) to extend this range.
+
+```javascript
+a = new BigNumber(1011, 2)          // "11"
+b = new BigNumber('zz.9', 36)       // "1295.25"
+c = a.plus(b)                       // "1306.25"
+```
+
+Performance is better if base 10 is NOT specified for decimal values. Only specify base 10 when it is desired that the number of decimal places of the input value be limited to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.
+
+A BigNumber is immutable in the sense that it is not changed by its methods.
+
+```javascript
+0.3 - 0.1                           // 0.19999999999999998
+x = new BigNumber(0.3)
+x.minus(0.1)                        // "0.2"
+x                                   // "0.3"
+```
+
+The methods that return a BigNumber can be chained.
+
+```javascript
+x.dividedBy(y).plus(z).times(9)
+x.times('1.23456780123456789e+9').plus(9876.5432321).dividedBy('4444562598.111772').integerValue()
+```
+
+Some of the longer method names have a shorter alias.
+
+```javascript
+x.squareRoot().dividedBy(y).exponentiatedBy(3).isEqualTo(x.sqrt().div(y).pow(3))    // true
+x.modulo(y).multipliedBy(z).eq(x.mod(y).times(z))                                   // true
+```
+
+As with JavaScript's Number type, there are [`toExponential`](http://mikemcl.github.io/bignumber.js/#toE), [`toFixed`](http://mikemcl.github.io/bignumber.js/#toFix) and [`toPrecision`](http://mikemcl.github.io/bignumber.js/#toP) methods.
+
+```javascript
+x = new BigNumber(255.5)
+x.toExponential(5)                  // "2.55500e+2"
+x.toFixed(5)                        // "255.50000"
+x.toPrecision(5)                    // "255.50"
+x.toNumber()                        //  255.5
+```
+
+ A base can be specified for [`toString`](http://mikemcl.github.io/bignumber.js/#toS). Performance is better if base 10 is NOT specified, i.e. use `toString()` not `toString(10)`. Only specify base 10 when it is desired that the number of decimal places be limited to the current [`DECIMAL_PLACES`](http://mikemcl.github.io/bignumber.js/#decimal-places) setting.
+
+ ```javascript
+ x.toString(16)                     // "ff.8"
+ ```
+
+There is a [`toFormat`](http://mikemcl.github.io/bignumber.js/#toFor) method which may be useful for internationalisation.
+
+```javascript
+y = new BigNumber('1234567.898765')
+y.toFormat(2)                       // "1,234,567.90"
+```
+
+The maximum number of decimal places of the result of an operation involving division (i.e. a division, square root, base conversion or negative power operation) is set using the `set` or `config` method of the `BigNumber` constructor.
+
+The other arithmetic operations always give the exact result.
+
+```javascript
+BigNumber.set({ DECIMAL_PLACES: 10, ROUNDING_MODE: 4 })
+
+x = new BigNumber(2)
+y = new BigNumber(3)
+z = x.dividedBy(y)                        // "0.6666666667"
+z.squareRoot()                            // "0.8164965809"
+z.exponentiatedBy(-3)                     // "3.3749999995"
+z.toString(2)                             // "0.1010101011"
+z.multipliedBy(z)                         // "0.44444444448888888889"
+z.multipliedBy(z).decimalPlaces(10)       // "0.4444444445"
+```
+
+There is a [`toFraction`](http://mikemcl.github.io/bignumber.js/#toFr) method with an optional *maximum denominator* argument
+
+```javascript
+y = new BigNumber(355)
+pi = y.dividedBy(113)               // "3.1415929204"
+pi.toFraction()                     // [ "7853982301", "2500000000" ]
+pi.toFraction(1000)                 // [ "355", "113" ]
+```
+
+and [`isNaN`](http://mikemcl.github.io/bignumber.js/#isNaN) and [`isFinite`](http://mikemcl.github.io/bignumber.js/#isF) methods, as `NaN` and `Infinity` are valid `BigNumber` values.
+
+```javascript
+x = new BigNumber(NaN)                                           // "NaN"
+y = new BigNumber(Infinity)                                      // "Infinity"
+x.isNaN() && !y.isNaN() && !x.isFinite() && !y.isFinite()        // true
+```
+
+The value of a BigNumber is stored in a decimal floating point format in terms of a coefficient, exponent and sign.
+
+```javascript
+x = new BigNumber(-123.456);
+x.c                                 // [ 123, 45600000000000 ]  coefficient (i.e. significand)
+x.e                                 // 2                        exponent
+x.s                                 // -1                       sign
+```
+
+For advanced usage, multiple BigNumber constructors can be created, each with their own independent configuration.
+
+```javascript
+// Set DECIMAL_PLACES for the original BigNumber constructor
+BigNumber.set({ DECIMAL_PLACES: 10 })
+
+// Create another BigNumber constructor, optionally passing in a configuration object
+BN = BigNumber.clone({ DECIMAL_PLACES: 5 })
+
+x = new BigNumber(1)
+y = new BN(1)
+
+x.div(3)                            // '0.3333333333'
+y.div(3)                            // '0.33333'
+```
+
+For further information see the [API](http://mikemcl.github.io/bignumber.js/) reference in the *doc* directory.
+
+## Test
+
+The *test/modules* directory contains the test scripts for each method.
+
+The tests can be run with Node.js or a browser. For Node.js use
+
+    $ npm test
+
+or
+
+    $ node test/test
+
+To test a single method, use, for example
+
+    $ node test/methods/toFraction
+
+For the browser, open *test/test.html*.
+
+## Build
+
+For Node, if [uglify-js](https://github.com/mishoo/UglifyJS2) is installed
+
+    npm install uglify-js -g
+
+then
+
+    npm run build
+
+will create *bignumber.min.js*.
+
+A source map will also be created in the root directory.

+
+    <h6>Why are trailing fractional zeros removed from BigNumbers?</h6>
+    <p>
+      Some arbitrary-precision libraries retain trailing fractional zeros as they can indicate the
+      precision of a value. This can be useful but the results of arithmetic operations can be
+      misleading.
+    </p>
+    <pre>
+x = new BigDecimal("1.0")
+y = new BigDecimal("1.1000")
+z = x.add(y)                      // 2.1000
+
+x = new BigDecimal("1.20")
+y = new BigDecimal("3.45000")
+z = x.multiply(y)                 // 4.1400000</pre>
+    <p>
+      To specify the precision of a value is to specify that the value lies
+      within a certain range.
+    </p>
+    <p>
+      In the first example, <code>x</code> has a value of <code>1.0</code>. The trailing zero shows
+      the precision of the value, implying that it is in the range <code>0.95</code> to
+      <code>1.05</code>. Similarly, the precision indicated by the trailing zeros of <code>y</code>
+      indicates that the value is in the range <code>1.09995</code> to <code>1.10005</code>.
+    </p>
+    <p>
+      If we  add the two lowest values in the ranges we have, <code>0.95 + 1.09995 = 2.04995</code>,
+      and if we add the two highest values we have, <code>1.05 + 1.10005 = 2.15005</code>, so the
+      range of the result of the addition implied by the precision of its operands is
+      <code>2.04995</code> to <code>2.15005</code>.
+    </p>
+    <p>
+      The result given by BigDecimal of <code>2.1000</code> however, indicates that the value is in
+      the range <code>2.09995</code> to <code>2.10005</code> and therefore the precision implied by
+      its trailing zeros may be misleading.
+    </p>
+    <p>
+      In the second example, the true range is <code>4.122744</code> to <code>4.157256</code> yet
+      the BigDecimal answer of <code>4.1400000</code> indicates a range of <code>4.13999995</code>
+      to  <code>4.14000005</code>. Again, the precision implied by the trailing zeros may be
+      misleading.
+    </p>
+    <p>
+      This library, like binary floating point and most calculators, does not retain trailing
+      fractional zeros. Instead, the <code>toExponential</code>, <code>toFixed</code> and
+      <code>toPrecision</code> methods enable trailing zeros to be added if and when required.<br />

+Node.js body parsing middleware.
+
+Parse incoming request bodies in a middleware before your handlers, available
+under the `req.body` property.
+
+**Note** As `req.body`'s shape is based on user-controlled input, all
+properties and values in this object are untrusted and should be validated
+before trusting. For example, `req.body.foo.toString()` may fail in multiple
+ways, for example the `foo` property may not be there or may not be a string,
+and `toString` may not be a function and instead a string or other user input.
+
+[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
+
+_This does not handle multipart bodies_, due to their complex and typically
+large nature. For multipart bodies, you may be interested in the following
+modules:
+
+  * [busboy](https://www.npmjs.org/package/busboy#readme) and
+    [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
+  * [multiparty](https://www.npmjs.org/package/multiparty#readme) and
+    [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
+  * [formidable](https://www.npmjs.org/package/formidable#readme)
+  * [multer](https://www.npmjs.org/package/multer#readme)
+
+This module provides the following parsers:
+
+  * [JSON body parser](#bodyparserjsonoptions)
+  * [Raw body parser](#bodyparserrawoptions)
+  * [Text body parser](#bodyparsertextoptions)
+  * [URL-encoded form body parser](#bodyparserurlencodedoptions)
+
+Other body parsers you might be interested in:

+
+## Installation
+
+```sh
+$ npm install body-parser
+```
+
+## API
+
+```js
+var bodyParser = require('body-parser')
+```
+
+The `bodyParser` object exposes various factories to create middlewares. All
+middlewares will populate the `req.body` property with the parsed body when
+the `Content-Type` request header matches the `type` option, or an empty
+object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
+or an error occurred.
+
+The various errors returned by this module are described in the
+[errors section](#errors).
+
+### bodyParser.json([options])
+
+Returns middleware that only parses `json` and only looks at requests where
+the `Content-Type` header matches the `type` option. This parser accepts any
+Unicode encoding of the body and supports automatic inflation of `gzip` and
+`deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`).
+
+#### Options
+
+The `json` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### reviver
+
+The `reviver` option is passed directly to `JSON.parse` as the second
+argument. You can find more information on this argument
+[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
+
+##### strict
+
+When set to `true`, will only accept arrays and objects; when `false` will
+accept anything `JSON.parse` accepts. Defaults to `true`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function. If not a
+function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
+be an extension name (like `json`), a mime type (like `application/json`), or
+a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
+option is called as `fn(req)` and the request is parsed if it returns a truthy
+value. Defaults to `application/json`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.raw([options])
+
+Returns middleware that parses all bodies as a `Buffer` and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a `Buffer` object
+of the body.
+
+#### Options
+
+The `raw` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function.
+If not a function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this
+can be an extension name (like `bin`), a mime type (like
+`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
+`application/*`). If a function, the `type` option is called as `fn(req)`
+and the request is parsed if it returns a truthy value. Defaults to
+`application/octet-stream`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.text([options])
+
+Returns middleware that parses all bodies as a string and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` string containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a string of the
+body.
+
+#### Options
+
+The `text` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### defaultCharset
+
+Specify the default character set for the text content if the charset is not
+specified in the `Content-Type` header of the request. Defaults to `utf-8`.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function. If not
+a function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
+be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
+type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
+option is called as `fn(req)` and the request is parsed if it returns a
+truthy value. Defaults to `text/plain`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.urlencoded([options])
+
+Returns middleware that only parses `urlencoded` bodies and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser accepts only UTF-8 encoding of the body and supports automatic
+inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This object will contain
+key-value pairs, where the value can be a string or array (when `extended` is
+`false`), or any type (when `extended` is `true`).
+
+#### Options
+
+The `urlencoded` function takes an optional `options` object that may contain
+any of the following keys:
+
+##### extended
+
+The `extended` option allows to choose between parsing the URL-encoded data
+with the `querystring` library (when `false`) or the `qs` library (when
+`true`). The "extended" syntax allows for rich objects and arrays to be
+encoded into the URL-encoded format, allowing for a JSON-like experience
+with URL-encoded. For more information, please
+[see the qs library](https://www.npmjs.org/package/qs#readme).
+
+Defaults to `true`, but using the default has been deprecated. Please
+research into the difference between `qs` and `querystring` and choose the
+appropriate setting.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### parameterLimit
+
+The `parameterLimit` option controls the maximum number of parameters that
+are allowed in the URL-encoded data. If a request contains more parameters
+than this value, a 413 will be returned to the client. Defaults to `1000`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a string, array of strings, or a function. If not
+a function, `type` option is passed directly to the
+[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
+be an extension name (like `urlencoded`), a mime type (like
+`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
+`*/x-www-form-urlencoded`). If a function, the `type` option is called as
+`fn(req)` and the request is parsed if it returns a truthy value. Defaults
+to `application/x-www-form-urlencoded`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+## Errors
+
+The middlewares provided by this module create errors using the
+[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
+will typically have a `status`/`statusCode` property that contains the suggested
+HTTP response code, an `expose` property to determine if the `message` property
+should be displayed to the client, a `type` property to determine the type of
+error without matching against the `message`, and a `body` property containing
+the read body, if available.
+
+The following are the common errors created, though any error can come through
+for various reasons.
+
+### content encoding unsupported
+
+This error will occur when the request had a `Content-Encoding` header that
+contained an encoding but the "inflation" option was set to `false`. The
+`status` property is set to `415`, the `type` property is set to
+`'encoding.unsupported'`, and the `charset` property will be set to the
+encoding that is unsupported.
+
+### entity parse failed
+
+This error will occur when the request contained an entity that could not be
+parsed by the middleware. The `status` property is set to `400`, the `type`
+property is set to `'entity.parse.failed'`, and the `body` property is set to
+the entity value that failed parsing.
+
+### entity verify failed
+
+This error will occur when the request contained an entity that could not be
+failed verification by the defined `verify` option. The `status` property is
+set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
+`body` property is set to the entity value that failed verification.
+
+### request aborted
+
+This error will occur when the request is aborted by the client before reading
+the body has finished. The `received` property will be set to the number of
+bytes received before the request was aborted and the `expected` property is
+set to the number of expected bytes. The `status` property is set to `400`
+and `type` property is set to `'request.aborted'`.
+
+### request entity too large
+
+This error will occur when the request body's size is larger than the "limit"
+option. The `limit` property will be set to the byte limit and the `length`
+property will be set to the request body's length. The `status` property is
+set to `413` and the `type` property is set to `'entity.too.large'`.
+
+### request size did not match content length
+
+This error will occur when the request's length did not match the length from
+the `Content-Length` header. This typically occurs when the request is malformed,
+typically when the `Content-Length` header was calculated based on characters
+instead of bytes. The `status` property is set to `400` and the `type` property
+is set to `'request.size.invalid'`.
+
+### stream encoding should not be set
+
+This error will occur when something called the `req.setEncoding` method prior
+to this middleware. This module operates directly on bytes only and you cannot
+call `req.setEncoding` when using this module. The `status` property is set to
+`500` and the `type` property is set to `'stream.encoding.set'`.
+
+### stream is not readable
+
+This error will occur when the request is no longer readable when this middleware
+attempts to read it. This typically means something other than a middleware from
+this module read the reqest body already and the middleware was also configured to
+read the same request. The `status` property is set to `500` and the `type`
+property is set to `'stream.not.readable'`.
+
+### too many parameters
+
+This error will occur when the content of the request exceeds the configured
+`parameterLimit` for the `urlencoded` parser. The `status` property is set to
+`413` and the `type` property is set to `'parameters.too.many'`.
+
+### unsupported charset "BOGUS"
+
+This error will occur when the request had a charset parameter in the
+`Content-Type` header, but the `iconv-lite` module does not support it OR the
+parser does not support it. The charset is contained in the message as well
+as in the `charset` property. The `status` property is set to `415`, the
+`type` property is set to `'charset.unsupported'`, and the `charset` property
+is set to the charset that is unsupported.
+
+### unsupported content encoding "bogus"
+
+This error will occur when the request had a `Content-Encoding` header that
+contained an unsupported encoding. The encoding is contained in the message
+as well as in the `encoding` property. The `status` property is set to `415`,
+the `type` property is set to `'encoding.unsupported'`, and the `encoding`
+property is set to the encoding that is unsupported.
+
+## Examples
+
+### Express/Connect top-level generic
+
+This example demonstrates adding a generic JSON and URL-encoded parser as a
+top-level middleware, which will parse the bodies of all incoming requests.
+This is the simplest setup.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse application/x-www-form-urlencoded
+app.use(bodyParser.urlencoded({ extended: false }))
+
+// parse application/json
+app.use(bodyParser.json())
+
+app.use(function (req, res) {
+  res.setHeader('Content-Type', 'text/plain')
+  res.write('you posted:\n')
+  res.end(JSON.stringify(req.body, null, 2))
+})
+```
+
+### Express route-specific
+
+This example demonstrates adding body parsers specifically to the routes that
+need them. In general, this is the most recommended way to use body-parser with
+Express.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// create application/json parser
+var jsonParser = bodyParser.json()
+
+// create application/x-www-form-urlencoded parser
+var urlencodedParser = bodyParser.urlencoded({ extended: false })
+
+// POST /login gets urlencoded bodies
+app.post('/login', urlencodedParser, function (req, res) {
+  res.send('welcome, ' + req.body.username)
+})
+
+// POST /api/users gets JSON bodies
+app.post('/api/users', jsonParser, function (req, res) {
+  // create user in req.body
+})
+```
+
+### Change accepted type for parsers
+
+All the parsers accept a `type` option which allows you to change the
+`Content-Type` that the middleware will parse.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse various different custom JSON types as JSON
+app.use(bodyParser.json({ type: 'application/*+json' }))
+
+// parse some custom thing into a Buffer
+app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
+
+// parse an HTML body into a string
+app.use(bodyParser.text({ type: 'text/html' }))
+```

+
+Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install bytes
+```
+
+## Usage
+
+```js
+var bytes = require('bytes');
+```
+
+#### bytes(number｜string value, [options]): number｜string｜null
+
+Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
+
+**Arguments**
+
+| Name    | Type     | Description        |
+|---------|----------|--------------------|
+| value   | `number`｜`string` | Number value to format or string value to parse |
+| options | `Object` | Conversion options for `format` |
+
+**Returns**
+
+| Name    | Type             | Description                                     |
+|---------|------------------|-------------------------------------------------|
+| results | `string`｜`number`｜`null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
+
+**Example**
+
+```js
+bytes(1024);
+// output: '1KB'
+
+bytes('1KB');
+// output: 1024
+```
+
+#### bytes.format(number value, [options]): string｜null
+
+Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
+ rounded.
+
+**Arguments**
+
+| Name    | Type     | Description        |
+|---------|----------|--------------------|
+| value   | `number` | Value in bytes     |
+| options | `Object` | Conversion options |
+
+**Options**
+
+| Property          | Type   | Description                                                                             |
+|-------------------|--------|-----------------------------------------------------------------------------------------|
+| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
+| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
+| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
+| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
+| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
+
+**Returns**
+
+| Name    | Type             | Description                                     |
+|---------|------------------|-------------------------------------------------|
+| results | `string`｜`null` | Return null upon error. String value otherwise. |
+
+**Example**
+
+```js
+bytes.format(1024);
+// output: '1KB'
+
+bytes.format(1000);
+// output: '1000B'
+
+bytes.format(1000, {thousandsSeparator: ' '});
+// output: '1 000B'
+
+bytes.format(1024 * 1.7, {decimalPlaces: 0});
+// output: '2KB'
+
+bytes.format(1024, {unitSeparator: ' '});
+// output: '1 KB'
+```
+
+#### bytes.parse(string｜number value): number｜null
+
+Parse the string value into an integer in bytes. If no unit is given, or `value`
+is a number, it is assumed the value is in bytes.
+
+Supported units and abbreviations are as follows and are case-insensitive:
+
+  * `b` for bytes
+  * `kb` for kilobytes
+  * `mb` for megabytes
+  * `gb` for gigabytes
+  * `tb` for terabytes
+  * `pb` for petabytes
+
+The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
+
+**Arguments**
+
+| Name          | Type   | Description        |
+|---------------|--------|--------------------|
+| value   | `string`｜`number` | String to parse, or number in bytes.   |
+
+**Returns**
+
+| Name    | Type        | Description             |
+|---------|-------------|-------------------------|
+| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
+
+**Example**
+
+```js
+bytes.parse('1KB');
+// output: 1024
+
+bytes.parse('1024');
+// output: 1024
+
+bytes.parse(1024);
+// output: 1024
+```

+
+Create and parse HTTP `Content-Disposition` header
+
+## Installation
+
+```sh
+$ npm install content-disposition
+```
+
+## API
+
+```js
+var contentDisposition = require('content-disposition')
+```
+
+### contentDisposition(filename, options)
+
+Create an attachment `Content-Disposition` header value using the given file name,
+if supplied. The `filename` is optional and if no file name is desired, but you
+want to specify `options`, set `filename` to `undefined`.
+
+```js
+res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
+```
+
+**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
+header through a means different from `setHeader` in Node.js, you'll want to specify
+the `'binary'` encoding in Node.js.
+
+#### Options
+
+`contentDisposition` accepts these properties in the options object.
+
+##### fallback
+
+If the `filename` option is outside ISO-8859-1, then the file name is actually
+stored in a supplemental field for clients that support Unicode file names and
+a ISO-8859-1 version of the file name is automatically generated.
+
+This specifies the ISO-8859-1 file name to override the automatic generation or
+disables the generation all together, defaults to `true`.
+
+  - A string will specify the ISO-8859-1 file name to use in place of automatic
+    generation.
+  - `false` will disable including a ISO-8859-1 file name and only include the
+    Unicode version (unless the file name is already ISO-8859-1).
+  - `true` will enable automatic generation if the file name is outside ISO-8859-1.
+
+If the `filename` option is ISO-8859-1 and this option is specified and has a
+different value, then the `filename` option is encoded in the extended field
+and this set as the fallback field, even though they are both ISO-8859-1.
+
+##### type
+
+Specifies the disposition type, defaults to `"attachment"`. This can also be
+`"inline"`, or any other value (all values except inline are treated like
+`attachment`, but can convey additional information if both parties agree to
+it). The type is normalized to lower-case.
+
+### contentDisposition.parse(string)
+
+```js
+var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt')
+```
+
+Parse a `Content-Disposition` header string. This automatically handles extended
+("Unicode") parameters by decoding them and providing them under the standard
+parameter name. This will return an object with the following properties (examples
+are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
+
+ - `type`: The disposition type (always lower case). Example: `'attachment'`
+
+ - `parameters`: An object of the parameters in the disposition (name of parameter
+   always lower case and extended versions replace non-extended versions). Example:
+   `{filename: "€ rates.txt"}`
+
+## Examples
+
+### Send a file for download
+
+```js
+var contentDisposition = require('content-disposition')
+var destroy = require('destroy')
+var fs = require('fs')
+var http = require('http')
+var onFinished = require('on-finished')
+
+var filePath = '/path/to/public/plans.pdf'
+
+http.createServer(function onRequest (req, res) {
+  // set headers
+  res.setHeader('Content-Type', 'application/pdf')
+  res.setHeader('Content-Disposition', contentDisposition(filePath))
+
+  // send file
+  var stream = fs.createReadStream(filePath)
+  stream.pipe(res)
+  onFinished(res, function () {
+    destroy(stream)
+  })
+})
+```

+
+Create and parse HTTP Content-Type header according to RFC 7231
+
+## Installation
+
+```sh
+$ npm install content-type
+```
+
+## API
+
+```js
+var contentType = require('content-type')
+```
+
+### contentType.parse(string)
+
+```js
+var obj = contentType.parse('image/svg+xml; charset=utf-8')
+```
+
+Parse a content type string. This will return an object with the following
+properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The media type (the type and subtype, always lower case).
+   Example: `'image/svg+xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of parameter
+   always lower case). Example: `{charset: 'utf-8'}`
+
+Throws a `TypeError` if the string is missing or invalid.
+
+### contentType.parse(req)
+
+```js
+var obj = contentType.parse(req)
+```
+
+Parse the `content-type` header from the given `req`. Short-cut for
+`contentType.parse(req.headers['content-type'])`.
+
+Throws a `TypeError` if the `Content-Type` header is missing or invalid.
+
+### contentType.parse(res)
+
+```js
+var obj = contentType.parse(res)
+```
+
+Parse the `content-type` header set on the given `res`. Short-cut for
+`contentType.parse(res.getHeader('content-type'))`.
+
+Throws a `TypeError` if the `Content-Type` header is missing or invalid.
+
+### contentType.format(obj)
+
+```js
+var str = contentType.format({type: 'image/svg+xml'})
+```
+
+Format an object into a content type string. This will return a string of the
+content type for the given object with the following properties (examples are
+shown that produce the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of the
+   parameter will be lower-cased). Example: `{charset: 'utf-8'}`
+
+Throws a `TypeError` if the object contains an invalid type or parameter names.

+## API
+
+```js
+var cookie = require('cookie');
+```
+
+### cookie.parse(str, options)
+
+Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
+The `str` argument is the string representing a `Cookie` header value and `options` is an
+optional object containing additional parsing options.
+
+```js
+var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
+// { foo: 'bar', equation: 'E=mc^2' }
+```
+
+#### Options
+
+`cookie.parse` accepts these properties in the options object.
+
+##### decode
+
+Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
+has a limited character set (and must be a simple string), this function can be used to decode
+a previously-encoded cookie value into a JavaScript string or other object.
+
+The default function is the global `decodeURIComponent`, which will decode any URL-encoded
+sequences into their byte representations.
+
+**note** if an error is thrown from this function, the original, non-decoded cookie value will
+be returned as the cookie's value.
+
+### cookie.serialize(name, value, options)
+
+Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
+name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
+argument is an optional object containing additional serialization options.
+
+```js
+var setCookie = cookie.serialize('foo', 'bar');
+// foo=bar
+```
+
+#### Options
+
+`cookie.serialize` accepts these properties in the options object.
+
+##### domain
+
+Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no
+domain is set, and most clients will consider the cookie to apply to only the current domain.
+
+##### encode
+
+Specifies a function that will be used to encode a cookie's value. Since value of a cookie
+has a limited character set (and must be a simple string), this function can be used to encode
+a value into a string suited for a cookie's value.
+
+The default function is the global `encodeURIComponent`, which will encode a JavaScript string
+into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
+
+##### expires
+
+Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1].
+By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
+will delete it on a condition like exiting a web browser application.
+
+**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
+`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### httpOnly
+
+Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not allow client-side
+JavaScript to see the cookie in `document.cookie`.
+
+##### maxAge
+
+Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2].
+The given number will be converted to an integer by rounding down. By default, no maximum age is set.
+
+**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
+`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### path
+
+Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path
+is considered the ["default path"][rfc-6265-5.1.4].
+
+##### priority
+
+Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1].
+
+  - `'low'` will set the `Priority` attribute to `Low`.
+  - `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set.
+  - `'high'` will set the `Priority` attribute to `High`.
+
+More information about the different priority levels can be found in
+[the specification][rfc-west-cookie-priority-00-4.1].
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### sameSite
+
+Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-09-5.4.7].
+
+  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+  - `false` will not set the `SameSite` attribute.
+  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+  - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
+  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in
+[the specification][rfc-6265bis-09-5.4.7].
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### secure
+
+Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
+the server in the future if the browser does not have an HTTPS connection.
+
+## Example
+
+The following example uses this module in conjunction with the Node.js core HTTP server
+to prompt a user for their name and display it back on future visits.
+
+```js
+var cookie = require('cookie');
+var escapeHtml = require('escape-html');
+var http = require('http');
+var url = require('url');
+
+function onRequest(req, res) {
+  // Parse the query string
+  var query = url.parse(req.url, true, true).query;
+
+  if (query && query.name) {
+    // Set a new cookie with the name
+    res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
+      httpOnly: true,
+      maxAge: 60 * 60 * 24 * 7 // 1 week
+    }));
+
+    // Redirect back after setting cookie
+    res.statusCode = 302;
+    res.setHeader('Location', req.headers.referer || '/');
+    res.end();
+    return;
+  }
+
+  // Parse the cookies on the request
+  var cookies = cookie.parse(req.headers.cookie || '');
+
+  // Get the visitor name set in the cookie
+  var name = cookies.name;
+
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8');
+
+  if (name) {
+    res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
+  } else {
+    res.write('<p>Hello, new visitor!</p>');
+  }
+
+  res.write('<form method="GET">');
+  res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
+  res.end('</form>');
+}
+
+http.createServer(onRequest).listen(3000);

+
+
+A tiny node.js debugging utility modelled after node core's debugging technique.
+
+**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+ Note that PowerShell uses different syntax to set environment variables.
+
+ ```cmd
+ $env:DEBUG = "*,-not_this"
+  ```
+
+Then, run the program to be debugged as usual.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+  If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Environment Variables
+
+  When running through Node.js, you can set a few environment variables that will
+  change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+  __Note:__ The environment variables beginning with `DEBUG_` end up being
+  converted into an Options object that gets used with `%o`/`%O` formatters.
+  See the Node.js documentation for
+  [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+  for the complete list.
+
+## Formatters
+
+
+  Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+### Custom formatters
+
+  You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+## Browser support
+  You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+  or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+  if you don't want to build it yourself.
+
+  Debug's enable state is currently persisted by `localStorage`.
+  Consider the situation shown below where you have `worker:a` and `worker:b`,
+  and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example _stdout.js_:
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```

+This module is installed directly using `npm`:
+
+```sh
+$ npm install depd
+```
+
+This module can also be bundled with systems like
+[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/),
+though by default this module will alter it's API to no longer display or
+track deprecations.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var deprecate = require('depd')('my-module')
+```
+
+This library allows you to display deprecation messages to your users.
+This library goes above and beyond with deprecation warnings by
+introspection of the call stack (but only the bits that it is interested
+in).
+
+Instead of just warning on the first invocation of a deprecated
+function and never again, this module will warn on the first invocation
+of a deprecated function per unique call site, making it ideal to alert
+users of all deprecated uses across the code base, rather than just
+whatever happens to execute first.
+
+The deprecation warnings from this module also include the file and line
+information for the call into the module that the deprecated function was
+in.
+
+**NOTE** this library has a similar interface to the `debug` module, and
+this module uses the calling file to get the boundary for the call stacks,
+so you should always create a new `deprecate` object in each file and not
+within some central file.
+
+### depd(namespace)
+
+Create a new deprecate function that uses the given namespace name in the
+messages and will display the call site prior to the stack entering the
+file this function was called from. It is highly suggested you use the
+name of your module as the namespace.
+
+### deprecate(message)
+
+Call this function from deprecated code to display a deprecation message.
+This message will appear once per unique caller site. Caller site is the
+first call site in the stack in a different file from the caller of this
+function.
+
+If the message is omitted, a message is generated for you based on the site
+of the `deprecate()` call and will display the name of the function called,
+similar to the name displayed in a stack trace.
+
+### deprecate.function(fn, message)
+
+Call this function to wrap a given function in a deprecation message on any
+call to the function. An optional message can be supplied to provide a custom
+message.
+
+### deprecate.property(obj, prop, message)
+
+Call this function to wrap a given property on object in a deprecation message
+on any accessing or setting of the property. An optional message can be supplied
+to provide a custom message.
+
+The method must be called on the object where the property belongs (not
+inherited from the prototype).
+
+If the property is a data descriptor, it will be converted to an accessor
+descriptor in order to display the deprecation message.
+
+### process.on('deprecation', fn)
+
+This module will allow easy capturing of deprecation errors by emitting the
+errors as the type "deprecation" on the global `process`. If there are no
+listeners for this type, the errors are written to STDERR as normal, but if
+there are any listeners, nothing will be written to STDERR and instead only
+emitted. From there, you can write the errors in a different format or to a
+logging source.
+
+The error represents the deprecation and is emitted only once with the same
+rules as writing to STDERR. The error has the following properties:
+
+  - `message` - This is the message given by the library
+  - `name` - This is always `'DeprecationError'`
+  - `namespace` - This is the namespace the deprecation came from
+  - `stack` - This is the stack of the call to the deprecated thing
+
+Example `error.stack` output:
+
+```
+DeprecationError: my-cool-module deprecated oldfunction
+    at Object.<anonymous> ([eval]-wrapper:6:22)
+    at Module._compile (module.js:456:26)
+    at evalScript (node.js:532:25)
+    at startup (node.js:80:7)
+    at node.js:902:3
+```
+
+### process.env.NO_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
+is provided as a quick solution to silencing deprecation warnings from being
+output. The format of this is similar to that of `DEBUG`:
+
+```sh
+$ NO_DEPRECATION=my-module,othermod node app.js
+```
+
+This will suppress deprecations from being output for "my-module" and "othermod".
+The value is a list of comma-separated namespaces. To suppress every warning
+across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--no-deprecation` to the `node` executable will suppress
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not suppress the deperecations given to any "deprecation"
+event listeners, just the output to STDERR.
+
+### process.env.TRACE_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
+is provided as a solution to getting more detailed location information in deprecation
+warnings by including the entire stack trace. The format of this is the same as
+`NO_DEPRECATION`:
+
+```sh
+$ TRACE_DEPRECATION=my-module,othermod node app.js
+```
+
+This will include stack traces for deprecations being output for "my-module" and
+"othermod". The value is a list of comma-separated namespaces. To trace every
+warning across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--trace-deprecation` to the `node` executable will trace
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
+
+## Display
+
+![message](files/message.png)
+
+When a user calls a function in your library that you mark deprecated, they
+will see the following written to STDERR (in the given colors, similar colors
+and layout to the `debug` module):
+
+```
+bright cyan    bright yellow
+|              |          reset       cyan
+|              |          |           |
+▼              ▼          ▼           ▼
+my-cool-module deprecated oldfunction [eval]-wrapper:6:22
+▲              ▲          ▲           ▲
+|              |          |           |
+namespace      |          |           location of mycoolmod.oldfunction() call
+               |          deprecation message
+               the word "deprecated"
+```
+
+If the user redirects their STDERR to a file or somewhere that does not support
+colors, they see (similar layout to the `debug` module):
+
+```
+Sun, 15 Jun 2014 05:21:37 GMT my-cool-module deprecated oldfunction at [eval]-wrapper:6:22
+▲                             ▲              ▲          ▲              ▲
+|                             |              |          |              |
+timestamp of message          namespace      |          |             location of mycoolmod.oldfunction() call
+                                             |          deprecation message
+                                             the word "deprecated"
+```
+
+## Examples
+
+### Deprecating all calls to a function
+
+This will display a deprecated message about "oldfunction" being deprecated
+from "my-module" on STDERR.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+// message automatically derived from function name
+// Object.oldfunction
+exports.oldfunction = deprecate.function(function oldfunction () {
+  // all calls to function are deprecated
+})
+
+// specific message
+exports.oldfunction = deprecate.function(function () {
+  // all calls to function are deprecated
+}, 'oldfunction')
+```
+
+### Conditionally deprecating a function call
+
+This will display a deprecated message about "weirdfunction" being deprecated
+from "my-module" on STDERR when called with less than 2 arguments.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  }
+}
+```
+
+When calling `deprecate` as a function, the warning is counted per call site
+within your own module, so you can display different deprecations depending
+on different situations and the users will still get all the warnings:
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  } else if (typeof arguments[0] !== 'string') {
+    // calls with non-string first argument are deprecated
+    deprecate('weirdfunction non-string first arg')
+  }
+}
+```
+
+### Deprecating property access
+
+This will display a deprecated message about "oldprop" being deprecated
+from "my-module" on STDERR when accessed. A deprecation will be displayed
+when setting the value and when getting the value.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.oldprop = 'something'
+
+// message automatically derives from property name
+deprecate.property(exports, 'oldprop')
+
+// explicit message
+deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
+```

+
+Destroy a stream.
+
+This module is meant to ensure a stream gets destroyed, handling different APIs
+and Node.js bugs.
+
+## API
+
+```js
+var destroy = require('destroy')
+```
+
+### destroy(stream [, suppress])
+
+Destroy the given stream, and optionally suppress any future `error` events.
+
+In most cases, this is identical to a simple `stream.destroy()` call. The rules
+are as follows for a given stream:
+
+  1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
+     and add a listener to the `open` event to call `stream.close()` if it is
+     fired. This is for a Node.js bug that will leak a file descriptor if
+     `.destroy()` is called before `open`.
+  2. If the `stream` is an instance of a zlib stream, then call `stream.destroy()`
+     and close the underlying zlib handle if open, otherwise call `stream.close()`.
+     This is for consistency across Node.js versions and a Node.js bug that will
+     leak a native zlib handle.
+  3. If the `stream` is not an instance of `Stream`, then nothing happens.
+  4. If the `stream` has a `.destroy()` method, then call it.
+
+The function returns the `stream` passed in as the argument.
+
+## Example
+
+```js
+var destroy = require('destroy')
+
+var fs = require('fs')
+var stream = fs.createReadStream('package.json')
+
+// ... and later
+destroy(stream)
+```

+Get the first event in a set of event emitters and event pairs,
+then clean up after itself.
+
+## Install
+
+```sh
+$ npm install ee-first
+```
+
+## API
+
+```js
+var first = require('ee-first')
+```
+
+### first(arr, listener)
+
+Invoke `listener` on the first event from the list specified in `arr`. `arr` is
+an array of arrays, with each array in the format `[ee, ...event]`. `listener`
+will be called only once, the first time any of the given events are emitted. If
+`error` is one of the listened events, then if that fires first, the `listener`
+will be given the `err` argument.
+
+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
+first argument emitted from an `error` event, if applicable; `ee` is the event
+emitter that fired; `event` is the string event name that fired; and `args` is an
+array of the arguments that were emitted on the event.
+
+```js
+var ee1 = new EventEmitter()
+var ee2 = new EventEmitter()
+
+first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+```
+
+#### .cancel()
+
+The group of listeners can be cancelled before being invoked and have all the event
+listeners removed from the underlying event emitters.
+
+```js
+var thunk = first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+
+// cancel and clean up
+thunk.cancel()
+```

+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install encodeurl
+```
+
+## API
+
+```js
+var encodeUrl = require('encodeurl')
+```
+
+### encodeUrl(url)
+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences.
+
+This function will take an already-encoded URL and encode all the non-URL
+code points (as UTF-8 byte sequences). This function will not encode the
+"%" character unless it is not part of a valid sequence (`%20` will be
+left as-is, but `%foo` will be encoded as `%25foo`).
+
+This encode is meant to be "safe" and does not throw errors. It will try as
+hard as it can to properly encode the given URL, including replacing any raw,
+unpaired surrogate pairs with the Unicode replacement character prior to
+encoding.
+
+This function is _similar_ to the intrinsic function `encodeURI`, except it
+will not encode the `%` character if that is part of a valid sequence, will
+not encode `[` and `]` (for IPv6 hostnames) and will replace raw, unpaired
+surrogate pairs with the Unicode replacement character (instead of throwing).
+
+## Examples
+
+### Encode a URL containing user-controled data
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+
+http.createServer(function onRequest (req, res) {
+  // get encoded form of inbound url
+  var url = encodeUrl(req.url)
+
+  // create html message
+  var body = '<p>Location ' + escapeHtml(url) + ' not found</p>'
+
+  // send a 404
+  res.statusCode = 404
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+  res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+  res.end(body, 'utf-8')
+})
+```
+
+### Encode a URL for use in a header field
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+var url = require('url')
+
+http.createServer(function onRequest (req, res) {
+  // parse inbound url
+  var href = url.parse(req)
+
+  // set new host for redirect
+  href.host = 'localhost'
+  href.protocol = 'https:'
+  href.slashes = true
+
+  // create location header
+  var location = encodeUrl(url.format(href))
+
+  // create html message
+  var body = '<p>Redirecting to new site: ' + escapeHtml(location) + '</p>'
+
+  // send a 301
+  res.statusCode = 301
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+  res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+  res.setHeader('Location', location)
+  res.end(body, 'utf-8')
+})
+```

+
+Create simple HTTP ETags
+
+This module generates HTTP ETags (as defined in RFC 7232) for use in
+HTTP responses.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install etag
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+<!-- eslint-disable no-undef -->
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if the generated ETag will include the weak validator mark (that
+is, the leading `W/`). The actual entity tag is the same. The default value
+is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.
+
+## Testing
+
+```sh
+$ npm test
+```
+
+## Benchmark
+
+```bash
+$ npm run-script bench

+[![Express Logo](https://i.cloudup.com/zfY6lL7eFa-3000x3000.png)](http://expressjs.com/)
+
+  Fast, unopinionated, minimalist web framework for [node](http://nodejs.org).
+
+  [![NPM Version][npm-version-image]][npm-url]
+  [![NPM Install Size][npm-install-size-image]][npm-install-size-url]
+  [![NPM Downloads][npm-downloads-image]][npm-downloads-url]
+
+```js
+const express = require('express')
+const app = express()
+
+app.get('/', function (req, res) {
+  res.send('Hello World')
+})
+
+app.listen(3000)
+```
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/).
+
+Before installing, [download and install Node.js](https://nodejs.org/en/download/).
+Node.js 0.10 or higher is required.
+
+If this is a brand new project, make sure to create a `package.json` first with
+the [`npm init` command](https://docs.npmjs.com/creating-a-package-json-file).
+
+Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```console
+$ npm install express
+```
+
+Follow [our installing guide](http://expressjs.com/en/starter/installing.html)
+for more information.
+
+## Features
+
+  * Robust routing
+  * Focus on high performance
+  * Super-high test coverage
+  * HTTP helpers (redirection, caching, etc)
+  * View system supporting 14+ template engines
+  * Content negotiation
+  * Executable for generating applications quickly
+
+## Docs & Community
+
+  * [Website and Documentation](http://expressjs.com/) - [[website repo](https://github.com/expressjs/expressjs.com)]
+  * [#express](https://webchat.freenode.net/?channels=express) on freenode IRC
+  * [GitHub Organization](https://github.com/expressjs) for Official Middleware & Modules
+  * Visit the [Wiki](https://github.com/expressjs/express/wiki)
+  * [Google Group](https://groups.google.com/group/express-js) for discussion
+  * [Gitter](https://gitter.im/expressjs/express) for support and discussion
+
+**PROTIP** Be sure to read [Migrating from 3.x to 4.x](https://github.com/expressjs/express/wiki/Migrating-from-3.x-to-4.x) as well as [New features in 4.x](https://github.com/expressjs/express/wiki/New-features-in-4.x).
+
+## Quick Start
+
+  The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below:
+
+  Install the executable. The executable's major version will match Express's:
+
+```console
+$ npm install -g express-generator@4
+```
+
+  Create the app:
+
+```console
+$ express /tmp/foo && cd /tmp/foo
+```
+
+  Install dependencies:
+
+```console
+$ npm install
+```
+
+  Start the server:
+
+```console
+$ npm start
+```
+
+  View the website at: http://localhost:3000
+
+## Philosophy
+
+  The Express philosophy is to provide small, robust tooling for HTTP servers, making
+  it a great solution for single page applications, websites, hybrids, or public
+  HTTP APIs.
+
+  Express does not force you to use any specific ORM or template engine. With support for over
+  14 template engines via [Consolidate.js](https://github.com/tj/consolidate.js),
+  you can quickly craft your perfect framework.
+
+## Examples
+
+  To view the examples, clone the Express repo and install the dependencies:
+
+```console
+$ git clone git://github.com/expressjs/express.git --depth 1
+$ cd express
+$ npm install
+```
+
+  Then run whichever example you want:
+
+```console
+$ node examples/content-negotiation
+```

+
+Node.js function to invoke as the final step to respond to HTTP request.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install finalhandler
+```
+
+## API
+
+```js
+var finalhandler = require('finalhandler')
+```
+
+### finalhandler(req, res, [options])
+
+Returns function to be invoked as the final step for the given `req` and `res`.
+This function is to be invoked as `fn(err)`. If `err` is falsy, the handler will
+write out a 404 response to the `res`. If it is truthy, an error response will
+be written out to the `res` or `res` will be terminated if a response has already
+started.
+
+When an error is written, the following information is added to the response:
+
+  * The `res.statusCode` is set from `err.status` (or `err.statusCode`). If
+    this value is outside the 4xx or 5xx range, it will be set to 500.
+  * The `res.statusMessage` is set according to the status code.
+  * The body will be the HTML of the status code message if `env` is
+    `'production'`, otherwise will be `err.stack`.
+  * Any headers specified in an `err.headers` object.
+
+The final handler will also unpipe anything from `req` when it is invoked.
+
+#### options.env
+
+By default, the environment is determined by `NODE_ENV` variable, but it can be
+overridden by this option.
+
+#### options.onerror
+
+Provide a function to be called with the `err` when it exists. Can be used for
+writing errors to a central location without excessive function generation. Called
+as `onerror(err, req, res)`.
+
+## Examples
+
+### always 404
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  done()
+})
+
+server.listen(3000)
+```
+
+### perform simple action
+
+```js
+var finalhandler = require('finalhandler')
+var fs = require('fs')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+
+  fs.readFile('index.html', function (err, buf) {
+    if (err) return done(err)
+    res.setHeader('Content-Type', 'text/html')
+    res.end(buf)
+  })
+})
+
+server.listen(3000)
+```
+
+### use with middleware-style functions
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+var serve = serveStatic('public')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  serve(req, res, done)
+})
+
+server.listen(3000)
+```
+
+### keep log of all errors
+
+```js
+var finalhandler = require('finalhandler')
+var fs = require('fs')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res, { onerror: logerror })
+
+  fs.readFile('index.html', function (err, buf) {
+    if (err) return done(err)
+    res.setHeader('Content-Type', 'text/html')
+    res.end(buf)
+  })
+})
+
+server.listen(3000)
+
+function logerror (err) {
+  console.error(err.stack || err.toString())
+}
+```

+Parse HTTP X-Forwarded-For header
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install forwarded
+```
+
+## API
+
+```js
+var forwarded = require('forwarded')
+```
+
+### forwarded(req)
+
+```js
+var addresses = forwarded(req)
+```
+
+Parse the `X-Forwarded-For` header from the request. Returns an array
+of the addresses, including the socket address for the `req`, in reverse
+order (i.e. index `0` is the socket address and the last index is the
+furthest address, typically the end-user).
+
+## Testing
+
+```sh
+$ npm test
+```

+
+HTTP response freshness testing
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```
+$ npm install fresh
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var fresh = require('fresh')
+```
+
+### fresh(reqHeaders, resHeaders)
+
+Check freshness of the response using request and response headers.
+
+When the response is still "fresh" in the client's cache `true` is
+returned, otherwise `false` is returned to indicate that the client
+cache is now stale and the full response should be sent.
+
+When a client sends the `Cache-Control: no-cache` request header to
+indicate an end-to-end reload request, this module will return `false`
+to make handling these requests transparent.
+
+## Known Issues
+
+This module is designed to only follow the HTTP specifications, not
+to work-around all kinda of client bugs (especially since this module
+typically does not recieve enough information to understand what the
+client actually is).
+
+There is a known issue that in certain versions of Safari, Safari
+will incorrectly make a request that allows this module to validate
+freshness of the resource even when Safari does not have a
+representation of the resource in the cache. The module
+[jumanji](https://www.npmjs.com/package/jumanji) can be used in
+an Express application to work-around this issue and also provides
+links to further reading on this Safari bug.
+
+## Example
+
+### API usage
+
+<!-- eslint-disable no-redeclare, no-undef -->
+
+```js
+var reqHeaders = { 'if-none-match': '"foo"' }
+var resHeaders = { 'etag': '"bar"' }
+fresh(reqHeaders, resHeaders)
+// => false
+
+var reqHeaders = { 'if-none-match': '"foo"' }
+var resHeaders = { 'etag': '"foo"' }
+fresh(reqHeaders, resHeaders)
+// => true
+```
+
+### Using with Node.js http server
+
+```js
+var fresh = require('fresh')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  // perform server logic
+  // ... including adding ETag / Last-Modified response headers
+
+  if (isFresh(req, res)) {
+    // client has a fresh copy of resource
+    res.statusCode = 304
+    res.end()
+    return
+  }
+
+  // send the resource
+  res.statusCode = 200
+  res.end('hello, world!')
+})
+
+function isFresh (req, res) {
+  return fresh(req.headers, {
+    'etag': res.getHeader('ETag'),
+    'last-modified': res.getHeader('Last-Modified')
+  })
+}
+
+server.listen(3000)

+Implementation of function.prototype.bind
+
+## Example
+
+I mainly do this for unit tests I run on phantomjs.
+PhantomJS does not have Function.prototype.bind :(
+
+```js
+Function.prototype.bind = require("function-bind")
+```
+
+## Installation
+
+`npm install function-bind`

+Get and robustly cache all JS language-level intrinsics at first require time.
+
+See the syntax described [in the JS spec](https://tc39.es/ecma262/#sec-well-known-intrinsic-objects) for reference.
+
+## Example
+
+```js
+var GetIntrinsic = require('get-intrinsic');
+var assert = require('assert');
+
+// static methods
+assert.equal(GetIntrinsic('%Math.pow%'), Math.pow);
+assert.equal(Math.pow(2, 3), 8);
+assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
+delete Math.pow;
+assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
+
+// instance methods
+var arr = [1];
+assert.equal(GetIntrinsic('%Array.prototype.push%'), Array.prototype.push);
+assert.deepEqual(arr, [1]);
+
+arr.push(2);
+assert.deepEqual(arr, [1, 2]);
+
+GetIntrinsic('%Array.prototype.push%').call(arr, 3);
+assert.deepEqual(arr, [1, 2, 3]);
+
+delete Array.prototype.push;
+GetIntrinsic('%Array.prototype.push%').call(arr, 4);
+assert.deepEqual(arr, [1, 2, 3, 4]);
+
+// missing features
+delete JSON.parse; // to simulate a real intrinsic that is missing in the environment
+assert.throws(() => GetIntrinsic('%JSON.parse%'));
+assert.equal(undefined, GetIntrinsic('%JSON.parse%', true));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
+

+Determine if the JS environment has Symbol support. Supports spec, or shams.
+
+## Example
+
+```js
+var hasSymbols = require('has-symbols');
+
+hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable.
+
+var hasSymbolsKinda = require('has-symbols/shams');
+hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec.
+```
+
+## Supported Symbol shams
+ - get-own-property-symbols [npm](https://www.npmjs.com/package/get-own-property-symbols) | [github](https://github.com/WebReflection/get-own-property-symbols)
+ - core-js [npm](https://www.npmjs.com/package/core-js) | [github](https://github.com/zloirock/core-js)
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+Create HTTP errors for Express, Koa, Connect, etc. with ease.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```console
+$ npm install http-errors
+```
+
+## Example
+
+```js
+var createError = require('http-errors')
+var express = require('express')
+var app = express()
+
+app.use(function (req, res, next) {
+  if (!req.user) return next(createError(401, 'Please login to view this page.'))
+  next()
+})
+```
+
+## API
+
+This is the current API, currently extracted from Koa and subject to change.
+
+### Error Properties
+
+- `expose` - can be used to signal if `message` should be sent to the client,
+  defaulting to `false` when `status` >= 500
+- `headers` - can be an object of header names to values to be sent to the
+  client, defaulting to `undefined`. When defined, the key names should all
+  be lower-cased
+- `message` - the traditional error message, which should be kept short and all
+  single line
+- `status` - the status code of the error, mirroring `statusCode` for general
+  compatibility
+- `statusCode` - the status code of the error, defaulting to `500`
+
+### createError([status], [message], [properties])
+
+Create a new error object with the given message `msg`.
+The error object inherits from `createError.HttpError`.
+
+```js
+var err = createError(404, 'This video does not exist!')
+```
+
+- `status: 500` - the status code as a number
+- `message` - the message of the error, defaulting to node's text for that status code.
+- `properties` - custom properties to attach to the object
+
+### createError([status], [error], [properties])
+
+Extend the given `error` object with `createError.HttpError`
+properties. This will not alter the inheritance of the given
+`error` object, and the modified `error` object is the
+return value.
+
+<!-- eslint-disable no-redeclare -->
+
+```js
+fs.readFile('foo.txt', function (err, buf) {
+  if (err) {
+    if (err.code === 'ENOENT') {
+      var httpError = createError(404, err, { expose: false })
+    } else {
+      var httpError = createError(500, err)
+    }
+  }
+})
+```
+
+- `status` - the status code as a number
+- `error` - the error object to extend
+- `properties` - custom properties to attach to the object
+
+### createError.isHttpError(val)
+
+Determine if the provided `val` is an `HttpError`. This will return `true`
+if the error inherits from the `HttpError` constructor of this module or
+matches the "duck type" for an error this module creates. All outputs from
+the `createError` factory will return `true` for this function, including
+if an non-`HttpError` was passed into the factory.
+
+### new createError\[code || name\](\[msg]\))
+
+Create a new error object with the given message `msg`.
+The error object inherits from `createError.HttpError`.
+
+```js
+var err = new createError.NotFound()
+```
+
+- `code` - the status code as a number
+- `name` - the name of the error as a "bumpy case", i.e. `NotFound` or `InternalServerError`.

+## Pure JS character encoding conversion [![Build Status](https://travis-ci.org/ashtuchkin/iconv-lite.svg?branch=master)](https://travis-ci.org/ashtuchkin/iconv-lite)
+
+ * Doesn't need native code compilation. Works on Windows and in sandboxed environments like [Cloud9](http://c9.io).
+ * Used in popular projects like [Express.js (body_parser)](https://github.com/expressjs/body-parser), 
+   [Grunt](http://gruntjs.com/), [Nodemailer](http://www.nodemailer.com/), [Yeoman](http://yeoman.io/) and others.
+ * Faster than [node-iconv](https://github.com/bnoordhuis/node-iconv) (see below for performance comparison).
+ * Intuitive encode/decode API
+ * Streaming support for Node v0.10+
+ * [Deprecated] Can extend Node.js primitives (buffers, streams) to support all iconv-lite encodings.
+ * In-browser usage via [Browserify](https://github.com/substack/node-browserify) (~180k gzip compressed with Buffer shim included).
+ * Typescript [type definition file](https://github.com/ashtuchkin/iconv-lite/blob/master/lib/index.d.ts) included.
+ * React Native is supported (need to explicitly `npm install` two more modules: `buffer` and `stream`).
+ * License: MIT.
+
+[![NPM Stats](https://nodei.co/npm/iconv-lite.png?downloads=true&downloadRank=true)](https://npmjs.org/packages/iconv-lite/)
+
+## Usage
+### Basic API
+```javascript
+var iconv = require('iconv-lite');
+
+// Convert from an encoded buffer to js string.
+str = iconv.decode(Buffer.from([0x68, 0x65, 0x6c, 0x6c, 0x6f]), 'win1251');
+
+// Convert from js string to an encoded buffer.
+buf = iconv.encode("Sample input string", 'win1251');
+
+// Check if encoding is supported
+iconv.encodingExists("us-ascii")
+```
+
+### Streaming API (Node v0.10+)
+```javascript
+
+// Decode stream (from binary stream to js strings)
+http.createServer(function(req, res) {
+    var converterStream = iconv.decodeStream('win1251');
+    req.pipe(converterStream);
+
+    converterStream.on('data', function(str) {
+        console.log(str); // Do something with decoded strings, chunk-by-chunk.
+    });
+});
+
+// Convert encoding streaming example
+fs.createReadStream('file-in-win1251.txt')
+    .pipe(iconv.decodeStream('win1251'))
+    .pipe(iconv.encodeStream('ucs2'))
+    .pipe(fs.createWriteStream('file-in-ucs2.txt'));
+
+// Sugar: all encode/decode streams have .collect(cb) method to accumulate data.
+http.createServer(function(req, res) {
+    req.pipe(iconv.decodeStream('win1251')).collect(function(err, body) {
+        assert(typeof body == 'string');
+        console.log(body); // full request body string
+    });
+});
+```
+
+### [Deprecated] Extend Node.js own encodings
+> NOTE: This doesn't work on latest Node versions. See [details](https://github.com/ashtuchkin/iconv-lite/wiki/Node-v4-compatibility).
+
+```javascript
+// After this call all Node basic primitives will understand iconv-lite encodings.
+iconv.extendNodeEncodings();
+
+// Examples:
+buf = new Buffer(str, 'win1251');
+buf.write(str, 'gbk');
+str = buf.toString('latin1');
+assert(Buffer.isEncoding('iso-8859-15'));
+Buffer.byteLength(str, 'us-ascii');
+
+http.createServer(function(req, res) {
+    req.setEncoding('big5');
+    req.collect(function(err, body) {
+        console.log(body);
+    });
+});
+
+fs.createReadStream("file.txt", "shift_jis");
+
+// External modules are also supported (if they use Node primitives, which they probably do).
+request = require('request');
+request({
+    url: "http://github.com/", 
+    encoding: "cp932"
+});
+
+// To remove extensions
+iconv.undoExtendNodeEncodings();
+```
+
+## Supported encodings
+
+ *  All node.js native encodings: utf8, ucs2 / utf16-le, ascii, binary, base64, hex.
+ *  Additional unicode encodings: utf16, utf16-be, utf-7, utf-7-imap.
+ *  All widespread singlebyte encodings: Windows 125x family, ISO-8859 family, 
+    IBM/DOS codepages, Macintosh family, KOI8 family, all others supported by iconv library. 
+    Aliases like 'latin1', 'us-ascii' also supported.
+ *  All widespread multibyte encodings: CP932, CP936, CP949, CP950, GB2312, GBK, GB18030, Big5, Shift_JIS, EUC-JP.
+
+See [all supported encodings on wiki](https://github.com/ashtuchkin/iconv-lite/wiki/Supported-Encodings).
+
+Most singlebyte encodings are generated automatically from [node-iconv](https://github.com/bnoordhuis/node-iconv). Thank you Ben Noordhuis and libiconv authors!
+
+Multibyte encodings are generated from [Unicode.org mappings](http://www.unicode.org/Public/MAPPINGS/) and [WHATWG Encoding Standard mappings](http://encoding.spec.whatwg.org/). Thank you, respective authors!
+

+## Encoding/decoding speed
+
+Comparison with node-iconv module (1000x256kb, on MacBook Pro, Core i5/2.6 GHz, Node v0.12.0). 
+Note: your results may vary, so please always check on your hardware.
+
+    operation             iconv@2.1.4   iconv-lite@0.4.7
+    ----------------------------------------------------------
+    encode('win1251')     ~96 Mb/s      ~320 Mb/s
+    decode('win1251')     ~95 Mb/s      ~246 Mb/s
+
+## BOM handling
+
+ * Decoding: BOM is stripped by default, unless overridden by passing `stripBOM: false` in options
+   (f.ex. `iconv.decode(buf, enc, {stripBOM: false})`).
+   A callback might also be given as a `stripBOM` parameter - it'll be called if BOM character was actually found.
+ * If you want to detect UTF-8 BOM when decoding other encodings, use [node-autodetect-decoder-stream](https://github.com/danielgindi/node-autodetect-decoder-stream) module.
+ * Encoding: No BOM added, unless overridden by `addBOM: true` option.
+
+## UTF-16 Encodings
+
+This library supports UTF-16LE, UTF-16BE and UTF-16 encodings. First two are straightforward, but UTF-16 is trying to be
+smart about endianness in the following ways:
+ * Decoding: uses BOM and 'spaces heuristic' to determine input endianness. Default is UTF-16LE, but can be 
+   overridden with `defaultEncoding: 'utf-16be'` option. Strips BOM unless `stripBOM: false`.
+ * Encoding: uses UTF-16LE and writes BOM by default. Use `addBOM: false` to override.
+
+## Other notes
+
+When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding).  
+Untranslatable characters are set to � or ?. No transliteration is currently supported.  
+Node versions 0.10.31 and 0.11.13 are buggy, don't use them (see #65, #77).  
+

+    // All japanese encodings are based on JIS X set of standards:
+    // JIS X 0201 - Single-byte encoding of ASCII + ¥ + Kana chars at 0xA1-0xDF.
+    // JIS X 0208 - Main set of 6879 characters, placed in 94x94 plane, to be encoded by 2 bytes. 
+    //              Has several variations in 1978, 1983, 1990 and 1997.
+    // JIS X 0212 - Supplementary plane of 6067 chars in 94x94 plane. 1990. Effectively dead.
+    // JIS X 0213 - Extension and modern replacement of 0208 and 0212. Total chars: 11233.
+    //              2 planes, first is superset of 0208, second - revised 0212.
+    //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
+
+    // Byte encodings are:
+    //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
+    //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
+    //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
+    //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
+    //               0x00-0x7F       - lower part of 0201
+    //               0x8E, 0xA1-0xDF - upper part of 0201
+    //               (0xA1-0xFE)x2   - 0208 plane (94x94).
+    //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
+    //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
+    //               Used as-is in ISO2022 family.
+    //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII, 
+    //                0201-1976 Roman, 0208-1978, 0208-1983.
+    //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
+    //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
+    //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
+    //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
+    //
+    // After JIS X 0213 appeared, Shift_JIS-2004, EUC-JISX0213 and ISO2022-JP-2004 followed, with just changing the planes.

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+# ipaddr.js — an IPv6 and IPv4 address manipulation library [![Build Status](https://travis-ci.org/whitequark/ipaddr.js.svg)](https://travis-ci.org/whitequark/ipaddr.js)
+
+ipaddr.js is a small (1.9K minified and gzipped) library for manipulating
+IP addresses in JavaScript environments. It runs on both CommonJS runtimes
+(e.g. [nodejs]) and in a web browser.
+
+ipaddr.js allows you to verify and parse string representation of an IP
+address, match it against a CIDR range or range list, determine if it falls
+into some reserved ranges (examples include loopback and private ranges),
+and convert between IPv4 and IPv4-mapped IPv6 addresses.
+
+[nodejs]: http://nodejs.org
+
+## Installation
+
+`npm install ipaddr.js`
+
+or
+
+`bower install ipaddr.js`
+
+## API
+
+ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS,
+it is exported from the module:
+
+```js
+var ipaddr = require('ipaddr.js');
+```
+
+The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4.
+
+### Global methods
+
+There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and
+`ipaddr.process`. All of them receive a string as a single parameter.
+
+The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or
+IPv6 address, and `false` otherwise. It does not throw any exceptions.
+
+The `ipaddr.parse` method returns an object representing the IP address,
+or throws an `Error` if the passed string is not a valid representation of an
+IP address.
+
+The `ipaddr.process` method works just like the `ipaddr.parse` one, but it
+automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts
+before returning. It is useful when you have a Node.js instance listening
+on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its
+equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4
+connections on your IPv6-only socket, but the remote address will be mangled.
+Use `ipaddr.process` method to automatically demangle it.
+
+### Object representation
+
+Parsing methods return an object which descends from `ipaddr.IPv6` or
+`ipaddr.IPv4`. These objects share some properties, but most of them differ.
+
+#### Shared properties
+
+One can determine the type of address by calling `addr.kind()`. It will return
+either `"ipv6"` or `"ipv4"`.
+
+An address can be converted back to its string representation with `addr.toString()`.
+Note that this method:
+ * does not return the original string used to create the object (in fact, there is
+   no way of getting that string)
+ * returns a compact representation (when it is applicable)
+
+A `match(range, bits)` method can be used to check if the address falls into a
+certain CIDR range.
+Note that an address can be (obviously) matched only against an address of the same type.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:db8:1234::1");
+var range = ipaddr.parse("2001:db8::");
+
+addr.match(range, 32); // => true
+```
+
+Alternatively, `match` can also be called as `match([range, bits])`. In this way,
+it can be used together with the `parseCIDR(string)` method, which parses an IP
+address together with a CIDR range.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:db8:1234::1");
+
+addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true
+```
+
+A `range()` method returns one of predefined names for several special ranges defined
+by IP protocols. The exact names (and their respective CIDR ranges) can be looked up
+in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"`
+(the default one) and `"reserved"`.
+
+You can match against your own range list by using
+`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example:
+
+```js
+var rangeList = {
+  documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ],
+  tunnelProviders: [
+    [ ipaddr.parse('2001:470::'), 32 ], // he.net
+    [ ipaddr.parse('2001:5c0::'), 32 ]  // freenet6
+  ]
+};
+ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders"
+```
+
+The addresses can be converted to their byte representation with `toByteArray()`.
+(Actually, JavaScript mostly does not know about byte buffers. They are emulated with
+arrays of numbers, each in range of 0..255.)
+
+```js
+var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com
+bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, <zeroes...>, 0x00, 0x68 ]
+```
+
+The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them
+have the same interface for both protocols, and are similar to global methods.
+
+`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address
+for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser.
+
+`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format.

+[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71
+
+#### IPv6 properties
+
+Sometimes you will want to convert IPv6 not to a compact string representation (with
+the `::` substitution); the `toNormalizedString()` method will return an address where
+all zeroes are explicit.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:0db8::0001");
+addr.toString(); // => "2001:db8::1"
+addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1"
+```
+
+The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped
+one, and `toIPv4Address()` will return an IPv4 object address.
+
+To access the underlying binary representation of the address, use `addr.parts`.
+
+```js
+var addr = ipaddr.parse("2001:db8:10::1234:DEAD");
+addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead]
+```
+
+A IPv6 zone index can be accessed via `addr.zoneId`:
+
+```js
+var addr = ipaddr.parse("2001:db8::%eth0");
+addr.zoneId // => 'eth0'
+```
+
+#### IPv4 properties
+
+`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address.
+
+To access the underlying representation of the address, use `addr.octets`.
+
+```js
+var addr = ipaddr.parse("192.168.1.1");
+addr.octets // => [192, 168, 1, 1]
+```
+
+`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or
+null if the netmask is not valid.
+
+```js
+ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28
+ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask()  == null
+```
+
+`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length.
+
+```js
+ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0"
+ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248"
+```
+
+`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation.
+```js
+ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255"
+```
+`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation.
+```js
+ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0"
+```
+
+#### Conversion
+
+IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays.
+
+The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object
+if the input satisfies the requirements. For IPv4 it has to be an array of four 8-bit values,
+while for IPv6 it has to be an array of sixteen 8-bit values.
+
+For example:
+```js
+var addr = ipaddr.fromByteArray([0x7f, 0, 0, 1]);
+addr.toString(); // => "127.0.0.1"
+```
+
+or
+
+```js
+var addr = ipaddr.fromByteArray([0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1])
+addr.toString(); // => "2001:db8::1"
+```
+
+Both objects also offer a `toByteArray()` method, which returns an array in network byte order (MSB).
+
+For example:
+```js
+var addr = ipaddr.parse("127.0.0.1");
+addr.toByteArray(); // => [0x7f, 0, 0, 1]
+```
+
+or
+
+```js
+var addr = ipaddr.parse("2001:db8::1");
+addr.toByteArray(); // => [0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1]
+```

+# jQuery
+
+> jQuery is a fast, small, and feature-rich JavaScript library.
+
+For information on how to get started and how to use jQuery, please see [jQuery's documentation](https://api.jquery.com/).
+For source files and issues, please visit the [jQuery repo](https://github.com/jquery/jquery).
+
+If upgrading, please see the [blog post for 3.6.0](https://blog.jquery.com/2021/03/02/jquery-3-6-0-released/). This includes notable differences from the previous version and a more readable changelog.
+
+## Including jQuery
+
+Below are some of the most common ways to include jQuery.
+
+### Browser
+
+#### Script tag
+
+```html
+<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
+```
+
+#### Babel
+
+[Babel](https://babeljs.io/) is a next generation JavaScript compiler. One of the features is the ability to use ES6/ES2015 modules now, even though browsers do not yet support this feature natively.
+
+```js
+import $ from "jquery";
+```
+
+#### Browserify/Webpack
+
+There are several ways to use [Browserify](http://browserify.org/) and [Webpack](https://webpack.github.io/). For more information on using these tools, please refer to the corresponding project's documentation. In the script, including jQuery will usually look like this...
+
+```js
+var $ = require( "jquery" );
+```
+
+#### AMD (Asynchronous Module Definition)
+
+AMD is a module format built for the browser. For more information, we recommend [require.js' documentation](https://requirejs.org/docs/whyamd.html).
+
+```js
+define( [ "jquery" ], function( $ ) {
+
+} );
+```
+
+### Node
+
+To include jQuery in [Node](https://nodejs.org/), first install with npm.
+
+```sh
+npm install jquery
+```
+
+For jQuery to work in Node, a window with a document is required. Since no such window exists natively in Node, one can be mocked by tools such as [jsdom](https://github.com/jsdom/jsdom). This can be useful for testing purposes.
+
+```js
+const { JSDOM } = require( "jsdom" );
+const { window } = new JSDOM( "" );
+const $ = require( "jquery" )( window );
+```

+// declare themselves as anonymous modules, and avoid setting a global if an

+
+Simple RFC 6838 media type parser
+
+## Installation
+
+```sh
+$ npm install media-typer
+```
+
+## API
+
+```js
+var typer = require('media-typer')
+```
+
+### typer.parse(string)
+
+```js
+var obj = typer.parse('image/svg+xml; charset=utf-8')
+```
+
+Parse a media type string. This will return an object with the following
+properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The type of the media type (always lower case). Example: `'image'`
+
+ - `subtype`: The subtype of the media type (always lower case). Example: `'svg'`
+
+ - `suffix`: The suffix of the media type (always lower case). Example: `'xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of parameter always lower case). Example: `{charset: 'utf-8'}`
+
+### typer.parse(req)
+
+```js
+var obj = typer.parse(req)
+```
+
+Parse the `content-type` header from the given `req`. Short-cut for
+`typer.parse(req.headers['content-type'])`.
+
+### typer.parse(res)
+
+```js
+var obj = typer.parse(res)
+```
+
+Parse the `content-type` header set on the given `res`. Short-cut for
+`typer.parse(res.getHeader('content-type'))`.
+
+### typer.format(obj)
+
+```js
+var obj = typer.format({type: 'image', subtype: 'svg', suffix: 'xml'})
+```
+
+Format an object into a media type string. This will return a string of the
+mime type for the given object. For the properties of the object, see the
+documentation for `typer.parse(string)`.

+
+HTTP verbs that Node.js core's HTTP parser supports.
+
+This module provides an export that is just like `http.METHODS` from Node.js core,
+with the following differences:
+
+  * All method names are lower-cased.
+  * Contains a fallback list of methods for Node.js versions that do not have a
+    `http.METHODS` export (0.10 and lower).
+  * Provides the fallback list when using tools like `browserify` without pulling
+    in the `http` shim module.
+
+## Install
+
+```bash
+$ npm install methods
+```
+
+## API
+
+```js
+var methods = require('methods')
+```
+
+### methods
+
+This is an array of lower-cased method names that Node.js supports. If Node.js
+provides the `http.METHODS` export, then this is the same array lower-cased,
+otherwise it is a snapshot of the verbs from Node.js 0.10.

+# mime-db
+
+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-url]
+[![Node.js Version][node-image]][node-url]
+[![Build Status][ci-image]][ci-url]
+[![Coverage Status][coveralls-image]][coveralls-url]
+
+This is a large database of mime types and information about them.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+### Database Download
+
+If you're crazy enough to use this in the browser, you can just grab the
+JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
+replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
+as the JSON format may change in the future.
+
+```
+https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db')
+
+// grab data on .js files
+var data = db['application/javascript']
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom-types.json` or
+`src/custom-suffix.json`.
+
+The `src/custom-types.json` file is a JSON object with the MIME type as the
+keys and the values being an object with the following keys:
+
+- `compressible` - leave out if you don't know, otherwise `true`/`false` to
+  indicate whether the data represented by the type is typically compressible.
+- `extensions` - include an array of file extensions that are associated with
+  the type.
+- `notes` - human-readable notes about the type, typically what the type is.
+- `sources` - include an array of URLs of where the MIME type and the associated
+  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
+  links to type aggregating sites and Wikipedia are _not acceptable_.
+
+To update the build, run `npm run build`.
+
+### Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.
+
+If that is not possible / feasible, they can be added directly here as a
+"custom" type. To do this, it is required to have a primary source that
+definitively lists the media type. If an extension is going to be listed as
+associateed with this media type, the source must definitively link the
+media type and extension as well.

+
+The ultimate javascript content-type utility.
+
+Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type,
+  `mime-types` simply returns `false`, so do
+  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- No `.define()` functionality
+- Bug fixes for `.lookup(path)`
+
+Otherwise, the API is compatible with `mime` 1.x.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json') // 'application/json'
+mime.lookup('.md') // 'text/markdown'
+mime.lookup('file.html') // 'text/html'
+mime.lookup('folder/file.js') // 'application/javascript'
+mime.lookup('folder/.htaccess') // false
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+When given an extension, `mime.lookup` is used to get the matching
+content-type, otherwise the given content-type is used. Then if the
+content-type does not already have a `charset` parameter, `mime.charset`
+is used to get the default charset and add to the returned content-type.
+
+```js
+mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+mime.contentType('text/html') // 'text/html; charset=utf-8'
+mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
+
+// from a full path
+mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]
+
+A map of extensions by content-type.

+
+## API - Queries
+
+### mime.lookup(path)
+Get the mime type associated with a file, if no mime type is found `application/octet-stream` is returned. Performs a case-insensitive lookup using the extension in `path` (the substring after the last '/' or '.').  E.g.
+
+```js
+var mime = require('mime');
+
+mime.lookup('/path/to/file.txt');         // => 'text/plain'
+mime.lookup('file.txt');                  // => 'text/plain'
+mime.lookup('.TXT');                      // => 'text/plain'
+mime.lookup('htm');                       // => 'text/html'
+```
+
+### mime.default_type
+Sets the mime type returned when `mime.lookup` fails to find the extension searched for. (Default is `application/octet-stream`.)
+
+### mime.extension(type)
+Get the default extension for `type`
+
+```js
+mime.extension('text/html');                 // => 'html'
+mime.extension('application/octet-stream');  // => 'bin'
+```
+
+### mime.charsets.lookup()
+
+Map mime-type to charset
+
+```js
+mime.charsets.lookup('text/plain');        // => 'UTF-8'
+```
+
+(The logic for charset lookups is pretty rudimentary.  Feel free to suggest improvements.)
+
+## API - Defining Custom Types
+
+Custom type mappings can be added on a per-project basis via the following APIs.
+
+### mime.define()
+
+Add custom mime/extension mappings
+
+```js
+mime.define({
+    'text/x-some-format': ['x-sf', 'x-sft', 'x-sfml'],
+    'application/x-my-type': ['x-mt', 'x-mtt'],
+    // etc ...
+});
+
+mime.lookup('x-sft');                 // => 'text/x-some-format'
+```
+
+The first entry in the extensions array is returned by `mime.extension()`. E.g.
+
+```js
+mime.extension('text/x-some-format'); // => 'x-sf'
+```
+
+### mime.load(filepath)
+
+Load mappings from an Apache ".types" format file
+
+```js
+mime.load('./my_project.types');
+```
+The .types file format is simple -  See the `types` dir for examples.

+# ms
+
+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+  and also make the charset user configurable.

+
+## v2.0.0-alpha (2012-05-15)
+
+This release is a rewrite. You should carefully test your application after
+upgrading to avoid problems. This release features many improvements, most
+importantly:
+
+* ~5x faster than v0.9.x for parsing query results
+* Support for pause() / resume() (for streaming rows)
+* Support for multiple statement queries
+* Support for stored procedures
+* Support for transactions
+* Support for binary columns (as blobs)
+* Consistent & well documented error handling
+* A new Connection class that has well defined semantics (unlike the old Client class).
+* Convenient escaping of objects / arrays that allows for simpler query construction
+* A significantly simpler code base
+* Many bug fixes & other small improvements (Closed 62 out of 66 GitHub issues)
+
+Below are a few notes on the upgrade process itself:
+
+The first thing you will run into is that the old `Client` class is gone and
+has been replaced with a less ambitious `Connection` class. So instead of
+`mysql.createClient()`, you now have to:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection({
+  host     : 'localhost',
+  user     : 'me',
+  password : 'secret',
+});
+
+connection.query('SELECT 1', function(err, rows) {
+  if (err) throw err;
+
+  console.log('Query result: ', rows);
+});
+
+connection.end();
+```
+
+The new `Connection` class does not try to handle re-connects, please study the
+`Server disconnects` section in the new Readme.
+
+Other than that, the interface has stayed very similar. Here are a few things
+to check out so:
+
+* BIGINT's are now cast into strings
+* Binary data is now cast to buffers
+* The `'row'` event on the `Query` object is now called `'result'` and will
+  also be emitted for queries that produce an OK/Error response.
+* Error handling is consistently defined now, check the Readme
+* Escaping has become more powerful which may break your code if you are
+  currently using objects to fill query placeholders.
+* Connections can now be established explicitly again, so you may wish to do so
+  if you want to handle connection errors specifically.
+
+That should be most of it, if you run into anything else, please send a patch
+or open an issue to improve this document.
+
+## v0.9.6 (2012-03-12)

+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/).
+
+Before installing, [download and install Node.js](https://nodejs.org/en/download/).
+Node.js 0.6 or higher is required.
+
+Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mysql
+```
+
+For information about the previous 0.9.x releases, visit the [v0.9 branch][].
+
+Sometimes I may also ask you to install the latest version from Github to check
+if a bugfix is working. In this case, please do:
+
+```sh
+$ npm install mysqljs/mysql
+```
+
+[v0.9 branch]: https://github.com/mysqljs/mysql/tree/v0.9
+
+## Introduction
+
+This is a node.js driver for mysql. It is written in JavaScript, does not
+require compiling, and is 100% MIT licensed.
+
+Here is an example on how to use it:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection({
+  host     : 'localhost',
+  user     : 'me',
+  password : 'secret',
+  database : 'my_db'
+});
+
+connection.connect();
+
+connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
+  if (error) throw error;
+  console.log('The solution is: ', results[0].solution);
+});
+
+connection.end();
+```
+
+From this example, you can learn the following:
+
+* Every method you invoke on a connection is queued and executed in sequence.
+* Closing the connection is done using `end()` which makes sure all remaining
+  queries are executed before sending a quit packet to the mysql server.

+
+## Establishing connections
+
+The recommended way to establish a connection is this:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection({
+  host     : 'example.org',
+  user     : 'bob',
+  password : 'secret'
+});
+
+connection.connect(function(err) {
+  if (err) {
+    console.error('error connecting: ' + err.stack);
+    return;
+  }
+
+  console.log('connected as id ' + connection.threadId);
+});
+```
+
+However, a connection can also be implicitly established by invoking a query:
+
+```js
+var mysql      = require('mysql');
+var connection = mysql.createConnection(...);
+
+connection.query('SELECT 1', function (error, results, fields) {
+  if (error) throw error;
+  // connected!
+});
+```
+
+Depending on how you like to handle your errors, either method may be
+appropriate. Any type of connection error (handshake or network) is considered
+a fatal error, see the [Error Handling](#error-handling) section for more
+information.
+
+## Connection options
+
+When establishing a connection, you can set the following options:
+
+* `host`: The hostname of the database you are connecting to. (Default:
+  `localhost`)
+* `port`: The port number to connect to. (Default: `3306`)
+* `localAddress`: The source IP address to use for TCP connection. (Optional)
+* `socketPath`: The path to a unix domain socket to connect to. When used `host`
+  and `port` are ignored.
+* `user`: The MySQL user to authenticate as.
+* `password`: The password of that MySQL user.
+* `database`: Name of the database to use for this connection (Optional).
+* `charset`: The charset for the connection. This is called "collation" in the SQL-level
+  of MySQL (like `utf8_general_ci`). If a SQL-level charset is specified (like `utf8mb4`)
+  then the default collation for that charset is used. (Default: `'UTF8_GENERAL_CI'`)
+* `timezone`: The timezone configured on the MySQL server. This is used to type cast server date/time values to JavaScript `Date` object and vice versa. This can be `'local'`, `'Z'`, or an offset in the form `+HH:MM` or `-HH:MM`. (Default: `'local'`)
+* `connectTimeout`: The milliseconds before a timeout occurs during the initial connection
+  to the MySQL server. (Default: `10000`)
+* `stringifyObjects`: Stringify objects instead of converting to values. See
+issue [#501](https://github.com/mysqljs/mysql/issues/501). (Default: `false`)
+* `insecureAuth`: Allow connecting to MySQL instances that ask for the old
+  (insecure) authentication method. (Default: `false`)
+* `typeCast`: Determines if column values should be converted to native
+   JavaScript types. (Default: `true`)
+* `queryFormat`: A custom query format function. See [Custom format](#custom-format).
+* `supportBigNumbers`: When dealing with big numbers (BIGINT and DECIMAL columns) in the database,
+  you should enable this option (Default: `false`).
+* `bigNumberStrings`: Enabling both `supportBigNumbers` and `bigNumberStrings` forces big numbers
+  (BIGINT and DECIMAL columns) to be always returned as JavaScript String objects (Default: `false`).
+  Enabling `supportBigNumbers` but leaving `bigNumberStrings` disabled will return big numbers as String
+  objects only when they cannot be accurately represented with [JavaScript Number objects] (http://ecma262-5.com/ELS5_HTML.htm#Section_8.5)
+  (which happens when they exceed the [-2^53, +2^53] range), otherwise they will be returned as
+  Number objects. This option is ignored if `supportBigNumbers` is disabled.
+* `dateStrings`: Force date types (TIMESTAMP, DATETIME, DATE) to be returned as strings rather than
+   inflated into JavaScript Date objects. Can be `true`/`false` or an array of type names to keep as
+   strings. (Default: `false`)
+* `debug`: Prints protocol details to stdout. Can be `true`/`false` or an array of packet type names
+   that should be printed. (Default: `false`)
+* `trace`: Generates stack traces on `Error` to include call site of library
+   entrance ("long stack traces"). Slight performance penalty for most calls.
+   (Default: `true`)
+* `localInfile`: Allow `LOAD DATA INFILE` to use the `LOCAL` modifier. (Default: `true`)
+* `multipleStatements`: Allow multiple mysql statements per query. Be careful
+  with this, it could increase the scope of SQL injection attacks. (Default: `false`)
+* `flags`: List of connection flags to use other than the default ones. It is
+  also possible to blacklist default ones. For more information, check
+  [Connection Flags](#connection-flags).
+* `ssl`: object with ssl parameters or a string containing name of ssl profile. See [SSL options](#ssl-options).
+
+
+In addition to passing these options as an object, you can also use a url
+string. For example:
+
+```js
+var connection = mysql.createConnection('mysql://user:pass@host/db?debug=true&charset=BIG5_CHINESE_CI&timezone=-0700');
+```
+
+Note: The query values are first attempted to be parsed as JSON, and if that
+fails assumed to be plaintext strings.
+
+### SSL options
+
+The `ssl` option in the connection options takes a string or an object. When given a string,
+it uses one of the predefined SSL profiles included. The following profiles are included:
+
+* `"Amazon RDS"`: this profile is for connecting to an Amazon RDS server and contains the
+  certificates from https://rds.amazonaws.com/doc/rds-ssl-ca-cert.pem and
+  https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem
+
+When connecting to other servers, you will need to provide an object of options, in the
+same format as [tls.createSecureContext](https://nodejs.org/api/tls.html#tls_tls_createsecurecontext_options).
+Please note the arguments expect a string of the certificate, not a file name to the
+certificate. Here is a simple example:
+
+```js
+var connection = mysql.createConnection({
+  host : 'localhost',
+  ssl  : {
+    ca : fs.readFileSync(__dirname + '/mysql-ca.crt')
+  }
+});
+```
+
+You can also connect to a MySQL server without properly providing the appropriate
+CA to trust. _You should not do this_.
+
+```js
+var connection = mysql.createConnection({
+  host : 'localhost',
+  ssl  : {
+    // DO NOT DO THIS
+    // set up your ca correctly to trust the connection
+    rejectUnauthorized: false
+  }
+});
+```
+
+### Connection flags
+
+If, for any reason, you would like to change the default connection flags, you
+can use the connection option `flags`. Pass a string with a comma separated list
+of items to add to the default flags. If you don't want a default flag to be used
+prepend the flag with a minus sign. To add a flag that is not in the default list,
+just write the flag name, or prefix it with a plus (case insensitive).
+
+```js
+var connection = mysql.createConnection({
+  // disable FOUND_ROWS flag, enable IGNORE_SPACE flag
+  flags: '-FOUND_ROWS,IGNORE_SPACE'
+});
+```
+
+The following flags are available:
+
+- `COMPRESS` - Enable protocol compression. This feature is not currently supported
+  by the Node.js implementation so cannot be turned on. (Default off)
+- `CONNECT_WITH_DB` - Ability to specify the database on connection. (Default on)
+- `FOUND_ROWS` - Send the found rows instead of the affected rows as `affectedRows`.
+  (Default on)
+- `IGNORE_SIGPIPE` - Don't issue SIGPIPE if network failures. This flag has no effect
+  on this Node.js implementation. (Default on)
+- `IGNORE_SPACE` - Let the parser ignore spaces before the `(` in queries. (Default on)
+- `INTERACTIVE` - Indicates to the MySQL server this is an "interactive" client. This
+  will use the interactive timeouts on the MySQL server and report as interactive in
+  the process list. (Default off)
+- `LOCAL_FILES` - Can use `LOAD DATA LOCAL`. This flag is controlled by the connection
+  option `localInfile`. (Default on)
+- `LONG_FLAG` - Longer flags in Protocol::ColumnDefinition320. (Default on)
+- `LONG_PASSWORD` - Use the improved version of Old Password Authentication.
+  (Default on)
+- `MULTI_RESULTS` - Can handle multiple resultsets for queries. (Default on)
+- `MULTI_STATEMENTS` - The client may send multiple statement per query or
+  statement prepare (separated by `;`). This flag is controlled by the connection
+  option `multipleStatements`. (Default off)
+- `NO_SCHEMA`
+- `ODBC` Special handling of ODBC behaviour. This flag has no effect on this Node.js
+  implementation. (Default on)
+- `PLUGIN_AUTH` - Uses the plugin authentication mechanism when connecting to the
+  MySQL server. This feature is not currently supported by the Node.js implementation
+  so cannot be turned on. (Default off)
+- `PROTOCOL_41` - Uses the 4.1 protocol. (Default on)
+- `PS_MULTI_RESULTS` - Can handle multiple resultsets for execute. (Default on)
+- `REMEMBER_OPTIONS` - This is specific to the C client, and has no effect on this
+  Node.js implementation. (Default off)
+- `RESERVED` - Old flag for the 4.1 protocol. (Default on)
+- `SECURE_CONNECTION` - Support native 4.1 authentication. (Default on)
+- `SSL` - Use SSL after handshake to encrypt data in transport. This feature is
+  controlled though the `ssl` connection option, so the flag has no effect.
+  (Default off)
+- `SSL_VERIFY_SERVER_CERT` - Verify the server certificate during SSL set up. This
+  feature is controlled though the `ssl.rejectUnauthorized` connection option, so
+  the flag has no effect. (Default off)
+- `TRANSACTIONS` - Asks for the transaction status flags. (Default on)
+
+## Terminating connections
+
+There are two ways to end a connection. Terminating a connection gracefully is
+done by calling the `end()` method:
+
+```js
+connection.end(function(err) {
+  // The connection is terminated now
+});
+```
+
+This will make sure all previously enqueued queries are still before sending a
+`COM_QUIT` packet to the MySQL server. If a fatal error occurs before the
+`COM_QUIT` packet can be sent, an `err` argument will be provided to the
+callback, but the connection will be terminated regardless of that.
+
+An alternative way to end the connection is to call the `destroy()` method.
+This will cause an immediate termination of the underlying socket.
+Additionally `destroy()` guarantees that no more events or callbacks will be
+triggered for the connection.
+
+```js
+connection.destroy();
+```
+
+Unlike `end()` the `destroy()` method does not take a callback argument.
+
+## Pooling connections
+
+Rather than creating and managing connections one-by-one, this module also
+provides built-in connection pooling using `mysql.createPool(config)`.
+[Read more about connection pooling](https://en.wikipedia.org/wiki/Connection_pool).
+
+Create a pool and use it directly:
+
+```js
+var mysql = require('mysql');
+var pool  = mysql.createPool({
+  connectionLimit : 10,
+  host            : 'example.org',
+  user            : 'bob',
+  password        : 'secret',
+  database        : 'my_db'
+});
+
+pool.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
+  if (error) throw error;
+  console.log('The solution is: ', results[0].solution);
+});
+```
+
+This is a shortcut for the `pool.getConnection()` -> `connection.query()` ->
+`connection.release()` code flow. Using `pool.getConnection()` is useful to
+share connection state for subsequent queries. This is because two calls to
+`pool.query()` may use two different connections and run in parallel. This is
+the basic structure:
+
+```js
+var mysql = require('mysql');
+var pool  = mysql.createPool(...);
+
+pool.getConnection(function(err, connection) {
+  if (err) throw err; // not connected!
+
+  // Use the connection
+  connection.query('SELECT something FROM sometable', function (error, results, fields) {
+    // When done with the connection, release it.
+    connection.release();
+
+    // Handle error after the release.
+    if (error) throw error;
+
+    // Don't use the connection here, it has been returned to the pool.
+  });
+});
+```
+
+If you would like to close the connection and remove it from the pool, use
+`connection.destroy()` instead. The pool will create a new connection the next
+time one is needed.
+
+Connections are lazily created by the pool. If you configure the pool to allow
+up to 100 connections, but only ever use 5 simultaneously, only 5 connections
+will be made. Connections are also cycled round-robin style, with connections
+being taken from the top of the pool and returning to the bottom.
+
+When a previous connection is retrieved from the pool, a ping packet is sent
+to the server to check if the connection is still good.
+
+## Pool options
+
+Pools accept all the same [options as a connection](#connection-options).
+When creating a new connection, the options are simply passed to the connection
+constructor. In addition to those options pools accept a few extras:
+
+* `acquireTimeout`: The milliseconds before a timeout occurs during the connection
+  acquisition. This is slightly different from `connectTimeout`, because acquiring
+  a pool connection does not always involve making a connection. If a connection
+  request is queued, the time the request spends in the queue does not count
+  towards this timeout. (Default: `10000`)
+* `waitForConnections`: Determines the pool's action when no connections are
+  available and the limit has been reached. If `true`, the pool will queue the
+  connection request and call it when one becomes available. If `false`, the
+  pool will immediately call back with an error. (Default: `true`)
+* `connectionLimit`: The maximum number of connections to create at once.
+  (Default: `10`)
+* `queueLimit`: The maximum number of connection requests the pool will queue
+  before returning an error from `getConnection`. If set to `0`, there is no
+  limit to the number of queued connection requests. (Default: `0`)
+
+## Pool events
+
+### acquire
+
+The pool will emit an `acquire` event when a connection is acquired from the pool.
+This is called after all acquiring activity has been performed on the connection,
+right before the connection is handed to the callback of the acquiring code.
+
+```js
+pool.on('acquire', function (connection) {
+  console.log('Connection %d acquired', connection.threadId);
+});
+```
+
+### connection
+
+The pool will emit a `connection` event when a new connection is made within the pool.
+If you need to set session variables on the connection before it gets used, you can
+listen to the `connection` event.
+
+```js
+pool.on('connection', function (connection) {
+  connection.query('SET SESSION auto_increment_increment=1')
+});
+```
+
+### enqueue
+
+The pool will emit an `enqueue` event when a callback has been queued to wait for
+an available connection.
+
+```js
+pool.on('enqueue', function () {
+  console.log('Waiting for available connection slot');
+});
+```
+
+### release
+
+The pool will emit a `release` event when a connection is released back to the
+pool. This is called after all release activity has been performed on the connection,
+so the connection will be listed as free at the time of the event.
+
+```js
+pool.on('release', function (connection) {
+  console.log('Connection %d released', connection.threadId);
+});
+```
+
+## Closing all the connections in a pool
+
+When you are done using the pool, you have to end all the connections or the
+Node.js event loop will stay active until the connections are closed by the
+MySQL server. This is typically done if the pool is used in a script or when
+trying to gracefully shutdown a server. To end all the connections in the
+pool, use the `end` method on the pool:
+
+```js
+pool.end(function (err) {
+  // all connections in the pool have ended
+});
+```
+
+The `end` method takes an _optional_ callback that you can use to know when
+all the connections are ended.
+
+**Once `pool.end` is called, `pool.getConnection` and other operations
+can no longer be performed.** Wait until all connections in the pool are
+released before calling `pool.end`. If you use the shortcut method
+`pool.query`, in place of `pool.getConnection` → `connection.query` →
+`connection.release`, wait until it completes.
+
+`pool.end` calls `connection.end` on every active connection in the pool.
+This queues a `QUIT` packet on the connection and sets a flag to prevent
+`pool.getConnection` from creating new connections. All commands / queries
+already in progress will complete, but new commands won't execute.
+
+## PoolCluster
+
+PoolCluster provides multiple hosts connection. (group & retry & selector)
+
+```js
+// create
+var poolCluster = mysql.createPoolCluster();
+
+// add configurations (the config is a pool config object)
+poolCluster.add(config); // add configuration with automatic name
+poolCluster.add('MASTER', masterConfig); // add a named configuration
+poolCluster.add('SLAVE1', slave1Config);
+poolCluster.add('SLAVE2', slave2Config);
+
+// remove configurations
+poolCluster.remove('SLAVE2'); // By nodeId
+poolCluster.remove('SLAVE*'); // By target group : SLAVE1-2
+
+// Target Group : ALL(anonymous, MASTER, SLAVE1-2), Selector : round-robin(default)
+poolCluster.getConnection(function (err, connection) {});
+
+// Target Group : MASTER, Selector : round-robin
+poolCluster.getConnection('MASTER', function (err, connection) {});
+
+// Target Group : SLAVE1-2, Selector : order
+// If can't connect to SLAVE1, return SLAVE2. (remove SLAVE1 in the cluster)
+poolCluster.on('remove', function (nodeId) {
+  console.log('REMOVED NODE : ' + nodeId); // nodeId = SLAVE1
+});
+
+// A pattern can be passed with *  as wildcard
+poolCluster.getConnection('SLAVE*', 'ORDER', function (err, connection) {});
+
+// The pattern can also be a regular expression
+poolCluster.getConnection(/^SLAVE[12]$/, function (err, connection) {});
+
+// of namespace : of(pattern, selector)
+poolCluster.of('*').getConnection(function (err, connection) {});
+
+var pool = poolCluster.of('SLAVE*', 'RANDOM');
+pool.getConnection(function (err, connection) {});
+pool.getConnection(function (err, connection) {});
+pool.query(function (error, results, fields) {});
+
+// close all connections
+poolCluster.end(function (err) {
+  // all connections in the pool cluster have ended
+});
+```
+
+### PoolCluster options
+
+* `canRetry`: If `true`, `PoolCluster` will attempt to reconnect when connection fails. (Default: `true`)
+* `removeNodeErrorCount`: If connection fails, node's `errorCount` increases.
+  When `errorCount` is greater than `removeNodeErrorCount`, remove a node in the `PoolCluster`. (Default: `5`)
+* `restoreNodeTimeout`: If connection fails, specifies the number of milliseconds
+  before another connection attempt will be made. If set to `0`, then node will be
+  removed instead and never re-used. (Default: `0`)
+* `defaultSelector`: The default selector. (Default: `RR`)
+  * `RR`: Select one alternately. (Round-Robin)
+  * `RANDOM`: Select the node by random function.
+  * `ORDER`: Select the first node available unconditionally.
+
+```js
+var clusterConfig = {
+  removeNodeErrorCount: 1, // Remove the node immediately when connection fails.
+  defaultSelector: 'ORDER'
+};
+
+var poolCluster = mysql.createPoolCluster(clusterConfig);
+```
+
+## Switching users and altering connection state
+
+MySQL offers a changeUser command that allows you to alter the current user and
+other aspects of the connection without shutting down the underlying socket:
+
+```js
+connection.changeUser({user : 'john'}, function(err) {
+  if (err) throw err;
+});
+```
+
+The available options for this feature are:
+
+* `user`: The name of the new user (defaults to the previous one).
+* `password`: The password of the new user (defaults to the previous one).
+* `charset`: The new charset (defaults to the previous one).
+* `database`: The new database (defaults to the previous one).
+
+A sometimes useful side effect of this functionality is that this function also
+resets any connection state (variables, transactions, etc.).
+
+Errors encountered during this operation are treated as fatal connection errors
+by this module.
+
+## Server disconnects
+
+You may lose the connection to a MySQL server due to network problems, the
+server timing you out, the server being restarted, or crashing. All of these
+events are considered fatal errors, and will have the `err.code =
+'PROTOCOL_CONNECTION_LOST'`.  See the [Error Handling](#error-handling) section
+for more information.
+
+Re-connecting a connection is done by establishing a new connection. Once
+terminated, an existing connection object cannot be re-connected by design.
+
+With Pool, disconnected connections will be removed from the pool freeing up
+space for a new connection to be created on the next getConnection call.
+
+With PoolCluster, disconnected connections will count as errors against the
+related node, incrementing the error code for that node. Once there are more than
+`removeNodeErrorCount` errors on a given node, it is removed from the cluster.
+When this occurs, the PoolCluster may emit a `POOL_NONEONLINE` error if there are
+no longer any matching nodes for the pattern. The `restoreNodeTimeout` config can
+be set to restore offline nodes after a given timeout.
+
+## Performing queries
+
+The most basic way to perform a query is to call the `.query()` method on an object
+(like a `Connection`, `Pool`, or `PoolNamespace` instance).
+
+The simplest form of .`query()` is `.query(sqlString, callback)`, where a SQL string
+is the first argument and the second is a callback:
+
+```js
+connection.query('SELECT * FROM `books` WHERE `author` = "David"', function (error, results, fields) {
+  // error will be an Error if one occurred during the query
+  // results will contain the results of the query
+  // fields will contain information about the returned results fields (if any)
+});
+```
+
+The second form `.query(sqlString, values, callback)` comes when using
+placeholder values (see [escaping query values](#escaping-query-values)):
+
+```js
+connection.query('SELECT * FROM `books` WHERE `author` = ?', ['David'], function (error, results, fields) {
+  // error will be an Error if one occurred during the query
+  // results will contain the results of the query
+  // fields will contain information about the returned results fields (if any)
+});
+```
+
+The third form `.query(options, callback)` comes when using various advanced
+options on the query, like [escaping query values](#escaping-query-values),
+[joins with overlapping column names](#joins-with-overlapping-column-names),
+[timeouts](#timeout), and [type casting](#type-casting).
+
+```js
+connection.query({
+  sql: 'SELECT * FROM `books` WHERE `author` = ?',
+  timeout: 40000, // 40s
+  values: ['David']
+}, function (error, results, fields) {
+  // error will be an Error if one occurred during the query
+  // results will contain the results of the query
+  // fields will contain information about the returned results fields (if any)
+});
+```
+
+Note that a combination of the second and third forms can be used where the
+placeholder values are passed as an argument and not in the options object.
+The `values` argument will override the `values` in the option object.
+
+```js
+connection.query({
+    sql: 'SELECT * FROM `books` WHERE `author` = ?',
+    timeout: 40000, // 40s
+  },
+  ['David'],
+  function (error, results, fields) {
+    // error will be an Error if one occurred during the query
+    // results will contain the results of the query
+    // fields will contain information about the returned results fields (if any)
+  }
+);
+```
+
+If the query only has a single replacement character (`?`), and the value is
+not `null`, `undefined`, or an array, it can be passed directly as the second
+argument to `.query`:
+
+```js
+connection.query(
+  'SELECT * FROM `books` WHERE `author` = ?',
+  'David',
+  function (error, results, fields) {
+    // error will be an Error if one occurred during the query
+    // results will contain the results of the query
+    // fields will contain information about the returned results fields (if any)
+  }
+);
+```
+
+## Escaping query values
+
+**Caution** These methods of escaping values only works when the
+[NO_BACKSLASH_ESCAPES](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_no_backslash_escapes)
+SQL mode is disabled (which is the default state for MySQL servers).
+
+In order to avoid SQL Injection attacks, you should always escape any user
+provided data before using it inside a SQL query. You can do so using the
+`mysql.escape()`, `connection.escape()` or `pool.escape()` methods:
+
+```js
+var userId = 'some user provided value';
+var sql    = 'SELECT * FROM users WHERE id = ' + connection.escape(userId);
+connection.query(sql, function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+Alternatively, you can use `?` characters as placeholders for values you would
+like to have escaped like this:
+
+```js
+connection.query('SELECT * FROM users WHERE id = ?', [userId], function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+Multiple placeholders are mapped to values in the same order as passed. For example,
+in the following query `foo` equals `a`, `bar` equals `b`, `baz` equals `c`, and
+`id` will be `userId`:
+
+```js
+connection.query('UPDATE users SET foo = ?, bar = ?, baz = ? WHERE id = ?', ['a', 'b', 'c', userId], function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+This looks similar to prepared statements in MySQL, however it really just uses
+the same `connection.escape()` method internally.
+
+**Caution** This also differs from prepared statements in that all `?` are
+replaced, even those contained in comments and strings.
+
+Different value types are escaped differently, here is how:
+
+* Numbers are left untouched
+* Booleans are converted to `true` / `false`
+* Date objects are converted to `'YYYY-mm-dd HH:ii:ss'` strings
+* Buffers are converted to hex strings, e.g. `X'0fa5'`
+* Strings are safely escaped
+* Arrays are turned into list, e.g. `['a', 'b']` turns into `'a', 'b'`
+* Nested arrays are turned into grouped lists (for bulk inserts), e.g. `[['a',
+  'b'], ['c', 'd']]` turns into `('a', 'b'), ('c', 'd')`
+* Objects that have a `toSqlString` method will have `.toSqlString()` called
+  and the returned value is used as the raw SQL.
+* Objects are turned into `key = 'val'` pairs for each enumerable property on
+  the object. If the property's value is a function, it is skipped; if the
+  property's value is an object, toString() is called on it and the returned
+  value is used.
+* `undefined` / `null` are converted to `NULL`
+* `NaN` / `Infinity` are left as-is. MySQL does not support these, and trying
+  to insert them as values will trigger MySQL errors until they implement
+  support.
+
+This escaping allows you to do neat things like this:
+
+```js
+var post  = {id: 1, title: 'Hello MySQL'};
+var query = connection.query('INSERT INTO posts SET ?', post, function (error, results, fields) {
+  if (error) throw error;
+  // Neat!
+});
+console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
+```
+
+And the `toSqlString` method allows you to form complex queries with functions:
+
+```js
+var CURRENT_TIMESTAMP = { toSqlString: function() { return 'CURRENT_TIMESTAMP()'; } };
+var sql = mysql.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+To generate objects with a `toSqlString` method, the `mysql.raw()` method can
+be used. This creates an object that will be left un-touched when using in a `?`
+placeholder, useful for using functions as dynamic values:
+
+**Caution** The string provided to `mysql.raw()` will skip all escaping
+functions when used, so be careful when passing in unvalidated input.
+
+```js
+var CURRENT_TIMESTAMP = mysql.raw('CURRENT_TIMESTAMP()');
+var sql = mysql.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+If you feel the need to escape queries by yourself, you can also use the escaping
+function directly:
+
+```js
+var query = "SELECT * FROM posts WHERE title=" + mysql.escape("Hello MySQL");
+
+console.log(query); // SELECT * FROM posts WHERE title='Hello MySQL'
+```
+
+## Escaping query identifiers
+
+If you can't trust an SQL identifier (database / table / column name) because it is
+provided by a user, you should escape it with `mysql.escapeId(identifier)`,
+`connection.escapeId(identifier)` or `pool.escapeId(identifier)` like this:
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + connection.escapeId(sorter);
+connection.query(sql, function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+It also supports adding qualified identifiers. It will escape both parts.
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + connection.escapeId('posts.' + sorter);
+// -> SELECT * FROM posts ORDER BY `posts`.`date`
+```
+
+If you do not want to treat `.` as qualified identifiers, you can set the second
+argument to `true` in order to keep the string as a literal identifier:
+
+```js
+var sorter = 'date.2';
+var sql    = 'SELECT * FROM posts ORDER BY ' + connection.escapeId(sorter, true);
+// -> SELECT * FROM posts ORDER BY `date.2`
+```
+
+Alternatively, you can use `??` characters as placeholders for identifiers you would
+like to have escaped like this:
+
+```js
+var userId = 1;
+var columns = ['username', 'email'];
+var query = connection.query('SELECT ?? FROM ?? WHERE id = ?', [columns, 'users', userId], function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+
+console.log(query.sql); // SELECT `username`, `email` FROM `users` WHERE id = 1
+```
+**Please note that this last character sequence is experimental and syntax might change**
+
+When you pass an Object to `.escape()` or `.query()`, `.escapeId()` is used to avoid SQL injection in object keys.
+
+### Preparing Queries
+
+You can use mysql.format to prepare a query with multiple insertion points, utilizing the proper escaping for ids and values. A simple example of this follows:
+
+```js
+var sql = "SELECT * FROM ?? WHERE ?? = ?";
+var inserts = ['users', 'id', userId];
+sql = mysql.format(sql, inserts);
+```
+
+Following this you then have a valid, escaped query that you can then send to the database safely. This is useful if you are looking to prepare the query before actually sending it to the database. As mysql.format is exposed from SqlString.format you also have the option (but are not required) to pass in stringifyObject and timezone, allowing you provide a custom means of turning objects into strings, as well as a location-specific/timezone-aware Date.
+
+### Custom format
+
+If you prefer to have another type of query escape format, there's a connection configuration option you can use to define a custom format function. You can access the connection object if you want to use the built-in `.escape()` or any other connection function.
+
+Here's an example of how to implement another format:
+
+```js
+connection.config.queryFormat = function (query, values) {
+  if (!values) return query;
+  return query.replace(/\:(\w+)/g, function (txt, key) {
+    if (values.hasOwnProperty(key)) {
+      return this.escape(values[key]);
+    }
+    return txt;
+  }.bind(this));
+};
+
+connection.query("UPDATE posts SET title = :title", { title: "Hello MySQL" });
+```
+
+## Getting the id of an inserted row
+
+If you are inserting a row into a table with an auto increment primary key, you
+can retrieve the insert id like this:
+
+```js
+connection.query('INSERT INTO posts SET ?', {title: 'test'}, function (error, results, fields) {
+  if (error) throw error;
+  console.log(results.insertId);
+});
+```
+
+When dealing with big numbers (above JavaScript Number precision limit), you should
+consider enabling `supportBigNumbers` option to be able to read the insert id as a
+string, otherwise it will throw an error.
+
+This option is also required when fetching big numbers from the database, otherwise
+you will get values rounded to hundreds or thousands due to the precision limit.
+
+## Getting the number of affected rows
+
+You can get the number of affected rows from an insert, update or delete statement.
+
+```js
+connection.query('DELETE FROM posts WHERE title = "wrong"', function (error, results, fields) {
+  if (error) throw error;
+  console.log('deleted ' + results.affectedRows + ' rows');
+})
+```
+
+## Getting the number of changed rows
+
+You can get the number of changed rows from an update statement.
+
+"changedRows" differs from "affectedRows" in that it does not count updated rows
+whose values were not changed.
+
+```js
+connection.query('UPDATE posts SET ...', function (error, results, fields) {
+  if (error) throw error;
+  console.log('changed ' + results.changedRows + ' rows');
+})
+```
+
+## Getting the connection ID
+
+You can get the MySQL connection ID ("thread ID") of a given connection using the `threadId`
+property.
+
+```js
+connection.connect(function(err) {
+  if (err) throw err;
+  console.log('connected as id ' + connection.threadId);
+});
+```
+
+## Executing queries in parallel
+
+The MySQL protocol is sequential, this means that you need multiple connections
+to execute queries in parallel. You can use a Pool to manage connections, one
+simple approach is to create one connection per incoming http request.
+
+## Streaming query rows
+
+Sometimes you may want to select large quantities of rows and process each of
+them as they are received. This can be done like this:
+
+```js
+var query = connection.query('SELECT * FROM posts');
+query
+  .on('error', function(err) {
+    // Handle error, an 'end' event will be emitted after this as well
+  })
+  .on('fields', function(fields) {
+    // the field packets for the rows to follow
+  })
+  .on('result', function(row) {
+    // Pausing the connnection is useful if your processing involves I/O
+    connection.pause();
+
+    processRow(row, function() {
+      connection.resume();
+    });
+  })
+  .on('end', function() {
+    // all rows have been received
+  });
+```
+
+Please note a few things about the example above:
+
+* Usually you will want to receive a certain amount of rows before starting to
+  throttle the connection using `pause()`. This number will depend on the
+  amount and size of your rows.
+* `pause()` / `resume()` operate on the underlying socket and parser. You are
+  guaranteed that no more `'result'` events will fire after calling `pause()`.
+* You MUST NOT provide a callback to the `query()` method when streaming rows.
+* The `'result'` event will fire for both rows as well as OK packets
+  confirming the success of a INSERT/UPDATE query.
+* It is very important not to leave the result paused too long, or you may
+  encounter `Error: Connection lost: The server closed the connection.`
+  The time limit for this is determined by the
+  [net_write_timeout setting](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_net_write_timeout)
+  on your MySQL server.
+
+Additionally you may be interested to know that it is currently not possible to
+stream individual row columns, they will always be buffered up entirely. If you
+have a good use case for streaming large fields to and from MySQL, I'd love to
+get your thoughts and contributions on this.
+
+### Piping results with Streams
+
+The query object provides a convenience method `.stream([options])` that wraps
+query events into a [Readable Stream](http://nodejs.org/api/stream.html#stream_class_stream_readable)
+object. This stream can easily be piped downstream and provides automatic
+pause/resume, based on downstream congestion and the optional `highWaterMark`.
+The `objectMode` parameter of the stream is set to `true` and cannot be changed
+(if you need a byte stream, you will need to use a transform stream, like
+[objstream](https://www.npmjs.com/package/objstream) for example).
+
+For example, piping query results into another stream (with a max buffer of 5
+objects) is simply:
+
+```js
+connection.query('SELECT * FROM posts')
+  .stream({highWaterMark: 5})
+  .pipe(...);
+```
+
+## Multiple statement queries
+
+Support for multiple statements is disabled for security reasons (it allows for
+SQL injection attacks if values are not properly escaped). To use this feature
+you have to enable it for your connection:
+
+```js
+var connection = mysql.createConnection({multipleStatements: true});
+```
+
+Once enabled, you can execute multiple statement queries like any other query:
+
+```js
+connection.query('SELECT 1; SELECT 2', function (error, results, fields) {
+  if (error) throw error;
+  // `results` is an array with one element for every statement in the query:
+  console.log(results[0]); // [{1: 1}]
+  console.log(results[1]); // [{2: 2}]
+});
+```
+
+Additionally you can also stream the results of multiple statement queries:
+
+```js
+var query = connection.query('SELECT 1; SELECT 2');
+
+query
+  .on('fields', function(fields, index) {
+    // the fields for the result rows that follow
+  })
+  .on('result', function(row, index) {
+    // index refers to the statement this result belongs to (starts at 0)
+  });
+```
+
+If one of the statements in your query causes an error, the resulting Error
+object contains a `err.index` property which tells you which statement caused
+it. MySQL will also stop executing any remaining statements when an error
+occurs.
+
+Please note that the interface for streaming multiple statement queries is
+experimental and I am looking forward to feedback on it.
+
+## Stored procedures
+
+You can call stored procedures from your queries as with any other mysql driver.
+If the stored procedure produces several result sets, they are exposed to you
+the same way as the results for multiple statement queries.
+
+## Joins with overlapping column names
+
+When executing joins, you are likely to get result sets with overlapping column
+names.
+
+By default, node-mysql will overwrite colliding column names in the
+order the columns are received from MySQL, causing some of the received values
+to be unavailable.
+
+However, you can also specify that you want your columns to be nested below
+the table name like this:
+
+```js
+var options = {sql: '...', nestTables: true};
+connection.query(options, function (error, results, fields) {
+  if (error) throw error;
+  /* results will be an array like this now:
+  [{
+    table1: {
+      fieldA: '...',
+      fieldB: '...',
+    },
+    table2: {
+      fieldA: '...',
+      fieldB: '...',
+    },
+  }, ...]
+  */
+});
+```
+
+Or use a string separator to have your results merged.
+
+```js
+var options = {sql: '...', nestTables: '_'};
+connection.query(options, function (error, results, fields) {
+  if (error) throw error;
+  /* results will be an array like this now:
+  [{
+    table1_fieldA: '...',
+    table1_fieldB: '...',
+    table2_fieldA: '...',
+    table2_fieldB: '...',
+  }, ...]
+  */
+});
+```
+
+## Transactions
+
+Simple transaction support is available at the connection level:
+
+```js
+connection.beginTransaction(function(err) {
+  if (err) { throw err; }
+  connection.query('INSERT INTO posts SET title=?', title, function (error, results, fields) {
+    if (error) {
+      return connection.rollback(function() {
+        throw error;
+      });
+    }
+
+    var log = 'Post ' + results.insertId + ' added';
+
+    connection.query('INSERT INTO log SET data=?', log, function (error, results, fields) {
+      if (error) {
+        return connection.rollback(function() {
+          throw error;
+        });
+      }
+      connection.commit(function(err) {
+        if (err) {
+          return connection.rollback(function() {
+            throw err;
+          });
+        }
+        console.log('success!');
+      });
+    });
+  });
+});
+```
+Please note that beginTransaction(), commit() and rollback() are simply convenience
+functions that execute the START TRANSACTION, COMMIT, and ROLLBACK commands respectively.
+It is important to understand that many commands in MySQL can cause an implicit commit,
+as described [in the MySQL documentation](http://dev.mysql.com/doc/refman/5.5/en/implicit-commit.html)
+
+## Ping
+
+A ping packet can be sent over a connection using the `connection.ping` method. This
+method will send a ping packet to the server and when the server responds, the callback
+will fire. If an error occurred, the callback will fire with an error argument.
+
+```js
+connection.ping(function (err) {
+  if (err) throw err;
+  console.log('Server responded to ping');
+})
+```
+
+## Timeouts
+
+Every operation takes an optional inactivity timeout option. This allows you to
+specify appropriate timeouts for operations. It is important to note that these
+timeouts are not part of the MySQL protocol, and rather timeout operations through
+the client. This means that when a timeout is reached, the connection it occurred
+on will be destroyed and no further operations can be performed.
+
+```js
+// Kill query after 60s
+connection.query({sql: 'SELECT COUNT(*) AS count FROM big_table', timeout: 60000}, function (error, results, fields) {
+  if (error && error.code === 'PROTOCOL_SEQUENCE_TIMEOUT') {
+    throw new Error('too long to count table rows!');
+  }
+
+  if (error) {
+    throw error;
+  }
+
+  console.log(results[0].count + ' rows');
+});
+```
+
+## Error handling
+
+This module comes with a consistent approach to error handling that you should
+review carefully in order to write solid applications.
+
+Most errors created by this module are instances of the JavaScript [Error][]
+object. Additionally they typically come with two extra properties:
+
+* `err.code`: String, contains the MySQL server error symbol if the error is
+  a [MySQL server error][] (e.g. `'ER_ACCESS_DENIED_ERROR'`), a Node.js error
+  code if it is a Node.js error (e.g. `'ECONNREFUSED'`), or an internal error
+  code (e.g. `'PROTOCOL_CONNECTION_LOST'`).
+* `err.errno`: Number, contains the MySQL server error number. Only populated
+  from [MySQL server error][].
+* `err.fatal`: Boolean, indicating if this error is terminal to the connection
+  object. If the error is not from a MySQL protocol operation, this property
+  will not be defined.
+* `err.sql`: String, contains the full SQL of the failed query. This can be
+  useful when using a higher level interface like an ORM that is generating
+  the queries.
+* `err.sqlState`: String, contains the five-character SQLSTATE value. Only populated from [MySQL server error][].
+* `err.sqlMessage`: String, contains the message string that provides a
+  textual description of the error. Only populated from [MySQL server error][].
+
+[Error]: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Error
+[MySQL server error]: https://dev.mysql.com/doc/refman/5.5/en/server-error-reference.html
+
+Fatal errors are propagated to *all* pending callbacks. In the example below, a
+fatal error is triggered by trying to connect to an invalid port. Therefore the
+error object is propagated to both pending callbacks:
+
+```js
+var connection = require('mysql').createConnection({
+  port: 84943, // WRONG PORT
+});
+
+connection.connect(function(err) {
+  console.log(err.code); // 'ECONNREFUSED'
+  console.log(err.fatal); // true
+});
+
+connection.query('SELECT 1', function (error, results, fields) {
+  console.log(error.code); // 'ECONNREFUSED'
+  console.log(error.fatal); // true
+});
+```
+
+Normal errors however are only delegated to the callback they belong to.  So in
+the example below, only the first callback receives an error, the second query
+works as expected:
+
+```js
+connection.query('USE name_of_db_that_does_not_exist', function (error, results, fields) {
+  console.log(error.code); // 'ER_BAD_DB_ERROR'
+});
+
+connection.query('SELECT 1', function (error, results, fields) {
+  console.log(error); // null
+  console.log(results.length); // 1
+});
+```
+
+Last but not least: If a fatal errors occurs and there are no pending
+callbacks, or a normal error occurs which has no callback belonging to it, the
+error is emitted as an `'error'` event on the connection object. This is
+demonstrated in the example below:
+
+```js
+connection.on('error', function(err) {
+  console.log(err.code); // 'ER_BAD_DB_ERROR'
+});
+
+connection.query('USE name_of_db_that_does_not_exist');
+```
+
+Note: `'error'` events are special in node. If they occur without an attached
+listener, a stack trace is printed and your process is killed.
+
+**tl;dr:** This module does not want you to deal with silent failures. You
+should always provide callbacks to your method calls. If you want to ignore
+this advice and suppress unhandled errors, you can do this:
+
+```js
+// I am Chuck Norris:
+connection.on('error', function() {});
+```
+
+## Exception Safety
+
+This module is exception safe. That means you can continue to use it, even if
+one of your callback functions throws an error which you're catching using
+'uncaughtException' or a domain.
+
+## Type casting
+
+For your convenience, this driver will cast mysql types into native JavaScript
+types by default. The following mappings exist:
+
+### Number
+
+* TINYINT
+* SMALLINT
+* INT
+* MEDIUMINT
+* YEAR
+* FLOAT
+* DOUBLE
+
+### Date
+
+* TIMESTAMP
+* DATE
+* DATETIME
+
+### Buffer
+
+* TINYBLOB
+* MEDIUMBLOB
+* LONGBLOB
+* BLOB
+* BINARY
+* VARBINARY
+* BIT (last byte will be filled with 0 bits as necessary)
+
+### String
+
+**Note** text in the binary character set is returned as `Buffer`, rather
+than a string.
+
+* CHAR
+* VARCHAR
+* TINYTEXT
+* MEDIUMTEXT
+* LONGTEXT
+* TEXT
+* ENUM
+* SET
+* DECIMAL (may exceed float precision)
+* BIGINT (may exceed float precision)
+* TIME (could be mapped to Date, but what date would be set?)
+* GEOMETRY (never used those, get in touch if you do)
+
+It is not recommended (and may go away / change in the future) to disable type
+casting, but you can currently do so on either the connection:
+
+```js
+var connection = require('mysql').createConnection({typeCast: false});
+```
+
+Or on the query level:
+
+```js
+var options = {sql: '...', typeCast: false};
+var query = connection.query(options, function (error, results, fields) {
+  if (error) throw error;
+  // ...
+});
+```
+
+### Custom type casting
+
+You can also pass a function and handle type casting yourself. You're given some
+column information like database, table and name and also type and length. If you
+just want to apply a custom type casting to a specific type you can do it and then
+fallback to the default.
+
+The function is provided two arguments `field` and `next` and is expected to
+return the value for the given field by invoking the parser functions through
+the `field` object.
+
+The `field` argument is a `Field` object and contains data about the field that
+need to be parsed. The following are some of the properties on a `Field` object:
+
+  * `db` - a string of the database the field came from.
+  * `table` - a string of the table the field came from.
+  * `name` - a string of the field name.
+  * `type` - a string of the field type in all caps.
+  * `length` - a number of the field length, as given by the database.
+
+The `next` argument is a `function` that, when called, will return the default
+type conversion for the given field.
+
+When getting the field data, the following helper methods are present on the
+`field` object:
+
+  * `.string()` - parse the field into a string.
+  * `.buffer()` - parse the field into a `Buffer`.
+  * `.geometry()` - parse the field as a geometry value.
+
+The MySQL protocol is a text-based protocol. This means that over the wire, all
+field types are represented as a string, which is why only string-like functions
+are available on the `field` object. Based on the type information (like `INT`),
+the type cast should convert the string field into a different JavaScript type
+(like a `number`).
+
+Here's an example of converting `TINYINT(1)` to boolean:
+
+```js
+connection = mysql.createConnection({
+  typeCast: function (field, next) {
+    if (field.type === 'TINY' && field.length === 1) {
+      return (field.string() === '1'); // 1 = true, 0 = false
+    } else {
+      return next();
+    }
+  }
+});
+```
+
+__WARNING: YOU MUST INVOKE the parser using one of these three field functions
+in your custom typeCast callback. They can only be called once.__
+
+## Debugging and reporting problems
+
+If you are running into problems, one thing that may help is enabling the
+`debug` mode for the connection:
+
+```js
+var connection = mysql.createConnection({debug: true});
+```
+
+This will print all incoming and outgoing packets on stdout. You can also restrict debugging to
+packet types by passing an array of types to debug:
+
+```js
+var connection = mysql.createConnection({debug: ['ComQueryPacket', 'RowDataPacket']});
+```
+
+to restrict debugging to the query and data packets.
+
+If that does not help, feel free to open a GitHub issue. A good GitHub issue
+will have:
+
+* The minimal amount of code required to reproduce the problem (if possible)
+* As much debugging output and information about your environment (mysql
+  version, node version, os, etc.) as you can gather.
+
+## Security issues
+
+Security issues should not be first reported through GitHub or another public
+forum, but kept private in order for the collaborators to assess the report
+and either (a) devise a fix and plan a release date or (b) assert that it is
+not a security issue (in which case it can be posted in a public forum, like
+a GitHub issue).
+
+The primary private forum is email, either by emailing the module's author or
+opening a GitHub issue simply asking to whom a security issues should be
+addressed to without disclosing the issue or type of issue.
+
+An ideal report would include a clear indication of what the security issue is
+and how it would be exploited, ideally with an accompanying proof of concept
+("PoC") for collaborators to work against and validate potentional fixes against.
+
+## Contributing
+
+This project welcomes contributions from the community. Contributions are
+accepted using GitHub pull requests. If you're not familiar with making
+GitHub pull requests, please refer to the
+[GitHub documentation "Creating a pull request"](https://help.github.com/articles/creating-a-pull-request/).
+
+For a good pull request, we ask you provide the following:
+
+1. Try to include a clear description of your pull request in the description.
+   It should include the basic "what" and "why"s for the request.
+2. The tests should pass as best as you can. See the [Running tests](#running-tests)
+   section on how to run the different tests. GitHub will automatically run
+   the tests as well, to act as a safety net.
+3. The pull request should include tests for the change. A new feature should
+   have tests for the new feature and bug fixes should include a test that fails
+   without the corresponding code change and passes after they are applied.
+   The command `npm run test-cov` will generate a `coverage/` folder that
+   contains HTML pages of the code coverage, to better understand if everything
+   you're adding is being tested.
+4. If the pull request is a new feature, please be sure to include all
+   appropriate documentation additions in the `Readme.md` file as well.
+5. To help ensure that your code is similar in style to the existing code,
+   run the command `npm run lint` and fix any displayed issues.
+
+## Running tests
+
+The test suite is split into two parts: unit tests and integration tests.
+The unit tests run on any machine while the integration tests require a
+MySQL server instance to be setup.
+
+### Running unit tests
+
+```sh
+$ FILTER=unit npm test
+```
+
+### Running integration tests
+
+Set the environment variables `MYSQL_DATABASE`, `MYSQL_HOST`, `MYSQL_PORT`,
+`MYSQL_USER` and `MYSQL_PASSWORD`. `MYSQL_SOCKET` can also be used in place
+of `MYSQL_HOST` and `MYSQL_PORT` to connect over a UNIX socket. Then run
+`npm test`.
+
+For example, if you have an installation of mysql running on localhost:3306
+and no password set for the `root` user, run:
+
+```sh
+$ mysql -u root -e "CREATE DATABASE IF NOT EXISTS node_mysql_test"
+$ MYSQL_HOST=localhost MYSQL_PORT=3306 MYSQL_DATABASE=node_mysql_test MYSQL_USER=root MYSQL_PASSWORD= FILTER=integration npm test
+```
+
+## Todo
+
+* Prepared statements
+* Support for encodings other than UTF-8 / ASCII

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0

+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+

+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+
+An HTTP content negotiator for Node.js
+
+## Installation
+
+```sh
+$ npm install negotiator
+```
+
+## API
+
+```js
+var Negotiator = require('negotiator')
+```
+
+### Accept Negotiation
+
+```js
+availableMediaTypes = ['text/html', 'text/plain', 'application/json']
+
+// The negotiator constructor receives a request object
+negotiator = new Negotiator(request)
+
+// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
+
+negotiator.mediaTypes()
+// -> ['text/html', 'image/jpeg', 'application/*']
+
+negotiator.mediaTypes(availableMediaTypes)
+// -> ['text/html', 'application/json']
+
+negotiator.mediaType(availableMediaTypes)
+// -> 'text/html'
+```
+
+You can check a working example at `examples/accept.js`.
+
+#### Methods
+
+##### mediaType()
+
+Returns the most preferred media type from the client.
+
+##### mediaType(availableMediaType)
+
+Returns the most preferred media type from a list of available media types.
+
+##### mediaTypes()
+
+Returns an array of preferred media types ordered by the client preference.
+
+##### mediaTypes(availableMediaTypes)
+
+Returns an array of preferred media types ordered by priority from a list of
+available media types.
+
+### Accept-Language Negotiation
+
+```js
+negotiator = new Negotiator(request)
+
+availableLanguages = ['en', 'es', 'fr']
+
+// Let's say Accept-Language header is 'en;q=0.8, es, pt'
+
+negotiator.languages()
+// -> ['es', 'pt', 'en']
+
+negotiator.languages(availableLanguages)
+// -> ['es', 'en']
+
+language = negotiator.language(availableLanguages)
+// -> 'es'
+```
+
+You can check a working example at `examples/language.js`.
+
+#### Methods
+
+##### language()
+
+Returns the most preferred language from the client.
+
+##### language(availableLanguages)
+
+Returns the most preferred language from a list of available languages.
+
+##### languages()
+
+Returns an array of preferred languages ordered by the client preference.
+
+##### languages(availableLanguages)
+
+Returns an array of preferred languages ordered by priority from a list of
+available languages.
+
+### Accept-Charset Negotiation
+
+```js
+availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
+
+negotiator.charsets()
+// -> ['utf-8', 'iso-8859-1', 'utf-7']
+
+negotiator.charsets(availableCharsets)
+// -> ['utf-8', 'iso-8859-1']
+
+negotiator.charset(availableCharsets)
+// -> 'utf-8'
+```
+
+You can check a working example at `examples/charset.js`.
+
+#### Methods
+
+##### charset()
+
+Returns the most preferred charset from the client.
+
+##### charset(availableCharsets)
+
+Returns the most preferred charset from a list of available charsets.
+
+##### charsets()
+
+Returns an array of preferred charsets ordered by the client preference.
+
+##### charsets(availableCharsets)
+
+Returns an array of preferred charsets ordered by priority from a list of
+available charsets.
+
+### Accept-Encoding Negotiation
+
+```js
+availableEncodings = ['identity', 'gzip']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Encoding header is 'gzip, compress;q=0.2, identity;q=0.5'
+
+negotiator.encodings()
+// -> ['gzip', 'identity', 'compress']
+
+negotiator.encodings(availableEncodings)
+// -> ['gzip', 'identity']
+
+negotiator.encoding(availableEncodings)
+// -> 'gzip'
+```
+
+You can check a working example at `examples/encoding.js`.
+
+#### Methods
+
+##### encoding()
+
+Returns the most preferred encoding from the client.
+
+##### encoding(availableEncodings)
+
+Returns the most preferred encoding from a list of available encodings.

+# example
+
+## circular
+
+``` js
+var inspect = require('object-inspect');
+var obj = { a: 1, b: [3,4] };
+obj.c = obj;
+console.log(inspect(obj));
+```
+
+## dom element
+
+``` js
+var inspect = require('object-inspect');
+
+var d = document.createElement('div');
+d.setAttribute('id', 'beep');
+d.innerHTML = '<b>wooo</b><i>iiiii</i>';
+
+console.log(inspect([ d, { a: 3, b : 4, c: [5,6,[7,[8,[9]]]] } ]));
+```
+
+output:
+
+```
+[ <div id="beep">...</div>, { a: 3, b: 4, c: [ 5, 6, [ 7, [ 8, [ ... ] ] ] ] } ]
+```
+
+# methods
+
+``` js
+var inspect = require('object-inspect')
+```
+
+## var s = inspect(obj, opts={})
+
+Return a string `s` with the string representation of `obj` up to a depth of `opts.depth`.
+
+Additional options:
+  - `quoteStyle`: must be "single" or "double", if present. Default `'single'` for strings, `'double'` for HTML elements.
+  - `maxStringLength`: must be `0`, a positive integer, `Infinity`, or `null`, if present. Default `Infinity`.
+  - `customInspect`: When `true`, a custom inspect method function will be invoked (either undere the `util.inspect.custom` symbol, or the `inspect` property). When the string `'symbol'`, only the symbol method will be invoked. Default `true`.
+  - `indent`: must be "\t", `null`, or a positive integer. Default `null`.
+  - `numericSeparator`: must be a boolean, if present. Default `false`. If `true`, all numbers will be printed with numeric separators (eg, `1234.5678` will be printed as `'1_234.567_8'`)

+
+Execute a callback when a HTTP request closes, finishes, or errors.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install on-finished
+```
+
+## API
+
+```js
+var onFinished = require('on-finished')
+```
+
+### onFinished(res, listener)
+
+Attach a listener to listen for the response to finish. The listener will
+be invoked only once when the response finished. If the response finished
+to an error, the first argument will contain the error. If the response
+has already finished, the listener will be invoked.
+
+Listening to the end of a response would be used to close things associated
+with the response, like open files.
+
+Listener is invoked as `listener(err, res)`.
+
+<!-- eslint-disable handle-callback-err -->
+
+```js
+onFinished(res, function (err, res) {
+  // clean up open fds, etc.
+  // err contains the error if request error'd
+})
+```
+
+### onFinished(req, listener)
+
+Attach a listener to listen for the request to finish. The listener will
+be invoked only once when the request finished. If the request finished
+to an error, the first argument will contain the error. If the request
+has already finished, the listener will be invoked.
+
+Listening to the end of a request would be used to know when to continue
+after reading the data.
+
+Listener is invoked as `listener(err, req)`.
+
+<!-- eslint-disable handle-callback-err -->
+
+```js
+var data = ''
+
+req.setEncoding('utf8')
+req.on('data', function (str) {
+  data += str
+})
+
+onFinished(req, function (err, req) {
+  // data is read unless there is err
+})
+```
+
+### onFinished.isFinished(res)
+
+Determine if `res` is already finished. This would be useful to check and
+not even start certain operations if the response has already finished.
+
+### onFinished.isFinished(req)
+
+Determine if `req` is already finished. This would be useful to check and
+not even start certain operations if the request has already finished.
+
+## Special Node.js requests
+
+### HTTP CONNECT method
+
+The meaning of the `CONNECT` method from RFC 7231, section 4.3.6:
+
+> The CONNECT method requests that the recipient establish a tunnel to
+> the destination origin server identified by the request-target and,
+> if successful, thereafter restrict its behavior to blind forwarding
+> of packets, in both directions, until the tunnel is closed.  Tunnels
+> are commonly used to create an end-to-end virtual connection, through
+> one or more proxies, which can then be secured using TLS (Transport
+> Layer Security, [RFC5246]).
+
+In Node.js, these request objects come from the `'connect'` event on
+the HTTP server.
+
+When this module is used on a HTTP `CONNECT` request, the request is
+considered "finished" immediately, **due to limitations in the Node.js
+interface**. This means if the `CONNECT` request contains a request entity,
+the request will be considered "finished" even before it has been read.
+
+There is no such thing as a response object to a `CONNECT` request in
+Node.js, so there is no support for one.
+
+### HTTP Upgrade request
+
+The meaning of the `Upgrade` header from RFC 7230, section 6.1:
+
+> The "Upgrade" header field is intended to provide a simple mechanism
+> for transitioning from HTTP/1.1 to some other protocol on the same
+> connection.
+
+In Node.js, these request objects come from the `'upgrade'` event on
+the HTTP server.
+
+When this module is used on a HTTP request with an `Upgrade` header, the
+request is considered "finished" immediately, **due to limitations in the
+Node.js interface**. This means if the `Upgrade` request contains a request
+entity, the request will be considered "finished" even before it has been
+read.
+
+There is no such thing as a response object to a `Upgrade` request in
+Node.js, so there is no support for one.
+
+## Example
+
+The following code ensures that file descriptors are always closed
+once the response finishes.
+
+```js
+var destroy = require('destroy')
+var fs = require('fs')
+var http = require('http')
+var onFinished = require('on-finished')
+
+http.createServer(function onRequest (req, res) {
+  var stream = fs.createReadStream('package.json')
+  stream.pipe(res)
+  onFinished(res, function () {
+    destroy(stream)
+  })
+})
+```

+
+Parse a URL with memoization.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install parseurl
+```
+
+## API
+
+```js
+var parseurl = require('parseurl')
+```
+
+### parseurl(req)
+
+Parse the URL of the given request object (looks at the `req.url` property)
+and return the result. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.url` does
+not change will return a cached parsed object, rather than parsing again.
+
+### parseurl.original(req)
+
+Parse the original URL of the given request object and return the result.
+This works by trying to parse `req.originalUrl` if it is a string, otherwise
+parses `req.url`. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.originalUrl`
+does not change will return a cached parsed object, rather than parsing again.

+# Path-to-RegExp
+
+Turn an Express-style path string such as `/user/:name` into a regular expression.
+
+**Note:** This is a legacy branch. You should upgrade to `1.x`.
+
+## Usage
+
+```javascript
+var pathToRegexp = require('path-to-regexp');
+```
+
+### pathToRegexp(path, keys, options)
+
+ - **path** A string in the express format, an array of such strings, or a regular expression
+ - **keys** An array to be populated with the keys present in the url.  Once the function completes, this will be an array of strings.
+ - **options**
+   - **options.sensitive** Defaults to false, set this to true to make routes case sensitive
+   - **options.strict** Defaults to false, set this to true to make the trailing slash matter.
+   - **options.end** Defaults to true, set this to false to only match the prefix of the URL.
+
+```javascript
+var keys = [];
+var exp = pathToRegexp('/foo/:bar', keys);
+//keys = ['bar']
+//exp = /^\/foo\/(?:([^\/]+?))\/?$/i
+```
+
+## Live Demo
+
+You can see a live demo of this library in use at [express-route-tester](http://forbeslindesay.github.com/express-route-tester/).

+
+Determine address of proxied request
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install proxy-addr
+```
+
+## API
+
+```js
+var proxyaddr = require('proxy-addr')
+```
+
+### proxyaddr(req, trust)
+
+Return the address of the request, using the given `trust` parameter.
+
+The `trust` argument is a function that returns `true` if you trust
+the address, `false` if you don't. The closest untrusted address is
+returned.
+
+```js
+proxyaddr(req, function (addr) { return addr === '127.0.0.1' })
+proxyaddr(req, function (addr, i) { return i < 1 })
+```
+
+The `trust` arugment may also be a single IP address string or an
+array of trusted addresses, as plain IP addresses, CIDR-formatted
+strings, or IP/netmask strings.
+
+```js
+proxyaddr(req, '127.0.0.1')
+proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8'])
+proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0'])
+```
+
+This module also supports IPv6. Your IPv6 addresses will be normalized
+automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`).
+
+```js
+proxyaddr(req, '::1')
+proxyaddr(req, ['::1/128', 'fe80::/10'])
+```
+
+This module will automatically work with IPv4-mapped IPv6 addresses
+as well to support node.js in IPv6-only mode. This means that you do
+not have to specify both `::ffff:a00:1` and `10.0.0.1`.
+
+As a convenience, this module also takes certain pre-defined names
+in addition to IP addresses, which expand into IP addresses:
+
+```js
+proxyaddr(req, 'loopback')
+proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64'])
+```
+
+  * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and
+    `127.0.0.1`).
+  * `linklocal`: IPv4 and IPv6 link-local addresses (like
+    `fe80::1:1:1:1` and `169.254.0.1`).
+  * `uniquelocal`: IPv4 private addresses and IPv6 unique-local
+    addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`).
+
+When `trust` is specified as a function, it will be called for each
+address to determine if it is a trusted address. The function is
+given two arguments: `addr` and `i`, where `addr` is a string of
+the address to check and `i` is a number that represents the distance
+from the socket address.
+
+### proxyaddr.all(req, [trust])
+
+Return all the addresses of the request, optionally stopping at the
+first untrusted. This array is ordered from closest to furthest
+(i.e. `arr[0] === req.connection.remoteAddress`).
+
+```js
+proxyaddr.all(req)
+```
+
+The optional `trust` argument takes the same arguments as `trust`
+does in `proxyaddr(req, trust)`.
+
+```js
+proxyaddr.all(req, 'loopback')
+```
+
+### proxyaddr.compile(val)
+
+Compiles argument `val` into a `trust` function. This function takes
+the same arguments as `trust` does in `proxyaddr(req, trust)` and
+returns a function suitable for `proxyaddr(req, trust)`.
+
+```js
+var trust = proxyaddr.compile('loopback')
+var addr = proxyaddr(req, trust)
+```
+
+This function is meant to be optimized for use against every request.
+It is recommend to compile a trust function up-front for the trusted
+configuration and pass that to `proxyaddr(req, trust)` for each request.

+
+A querystring parsing and stringifying library with some added security.
+
+Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
+
+The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
+
+## Usage
+
+```javascript
+var qs = require('qs');
+var assert = require('assert');
+
+var obj = qs.parse('a=c');
+assert.deepEqual(obj, { a: 'c' });
+
+var str = qs.stringify(obj);
+assert.equal(str, 'a=c');
+```
+
+### Parsing Objects
+
+[](#preventEval)
+```javascript
+qs.parse(string, [options]);
+```
+
+**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
+For example, the string `'foo[bar]=baz'` converts to:
+
+```javascript
+assert.deepEqual(qs.parse('foo[bar]=baz'), {
+    foo: {
+        bar: 'baz'
+    }
+});
+```
+
+When using the `plainObjects` option the parsed value is returned as a null object, created via `Object.create(null)` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
+
+```javascript
+var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
+assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
+```
+
+By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties. *WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten. Always be careful with this option.
+
+```javascript
+var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
+assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
+```
+
+URI encoded strings work too:
+
+```javascript
+assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
+    a: { b: 'c' }
+});
+```
+
+You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
+
+```javascript
+assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
+    foo: {
+        bar: {
+            baz: 'foobarbaz'
+        }
+    }
+});
+```
+
+By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
+`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
+
+```javascript
+var expected = {
+    a: {
+        b: {
+            c: {
+                d: {
+                    e: {
+                        f: {
+                            '[g][h][i]': 'j'
+                        }
+                    }
+                }
+            }
+        }
+    }
+};
+var string = 'a[b][c][d][e][f][g][h][i]=j';
+assert.deepEqual(qs.parse(string), expected);
+```
+
+This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
+
+```javascript
+var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
+assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
+```
+
+The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
+
+For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
+
+```javascript
+var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
+assert.deepEqual(limited, { a: 'b' });
+```
+
+To bypass the leading question mark, use `ignoreQueryPrefix`:
+
+```javascript
+var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
+assert.deepEqual(prefixed, { a: 'b', c: 'd' });
+```
+
+An optional delimiter can also be passed:
+
+```javascript
+var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
+assert.deepEqual(delimited, { a: 'b', c: 'd' });
+```
+
+Delimiters can be a regular expression too:
+
+```javascript
+var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
+assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
+```
+
+Option `allowDots` can be used to enable dot notation:
+
+```javascript
+var withDots = qs.parse('a.b=c', { allowDots: true });
+assert.deepEqual(withDots, { a: { b: 'c' } });
+```
+
+If you have to deal with legacy browsers or services, there's
+also support for decoding percent-encoded octets as iso-8859-1:
+
+```javascript
+var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' });
+assert.deepEqual(oldCharset, { a: '§' });
+```
+
+Some services add an initial `utf8=✓` value to forms so that old
+Internet Explorer versions are more likely to submit the form as
+utf-8. Additionally, the server can check the value against wrong
+encodings of the checkmark character and detect that a query string
+or `application/x-www-form-urlencoded` body was *not* sent as
+utf-8, eg. if the form had an `accept-charset` parameter or the
+containing page had a different character set.
+
+**qs** supports this mechanism via the `charsetSentinel` option.
+If specified, the `utf8` parameter will be omitted from the
+returned object. It will be used to switch to `iso-8859-1`/`utf-8`
+mode depending on how the checkmark is encoded.
+
+**Important**: When you specify both the `charset` option and the
+`charsetSentinel` option, the `charset` will be overridden when
+the request contains a `utf8` parameter from which the actual
+charset can be deduced. In that sense the `charset` will behave
+as the default charset rather than the authoritative charset.
+
+```javascript
+var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', {
+    charset: 'iso-8859-1',
+    charsetSentinel: true
+});
+assert.deepEqual(detectedAsUtf8, { a: 'ø' });
+
+// Browsers encode the checkmark as &#10003; when submitting as iso-8859-1:
+var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', {
+    charset: 'utf-8',
+    charsetSentinel: true
+});
+assert.deepEqual(detectedAsIso8859_1, { a: 'ø' });
+```
+
+If you want to decode the `&#...;` syntax to the actual character,
+you can specify the `interpretNumericEntities` option as well:
+
+```javascript
+var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', {
+    charset: 'iso-8859-1',
+    interpretNumericEntities: true
+});
+assert.deepEqual(detectedAsIso8859_1, { a: '☺' });
+```
+
+It also works when the charset has been detected in `charsetSentinel`
+mode.
+
+### Parsing Arrays
+
+**qs** can also parse arrays using a similar `[]` notation:
+
+```javascript
+var withArray = qs.parse('a[]=b&a[]=c');
+assert.deepEqual(withArray, { a: ['b', 'c'] });
+```
+
+You may specify an index as well:
+
+```javascript
+var withIndexes = qs.parse('a[1]=c&a[0]=b');
+assert.deepEqual(withIndexes, { a: ['b', 'c'] });
+```
+
+Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
+to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
+their order:
+
+```javascript
+var noSparse = qs.parse('a[1]=b&a[15]=c');
+assert.deepEqual(noSparse, { a: ['b', 'c'] });
+```
+
+You may also use `allowSparse` option to parse sparse arrays:
+
+```javascript
+var sparseArray = qs.parse('a[1]=2&a[3]=5', { allowSparse: true });
+assert.deepEqual(sparseArray, { a: [, '2', , '5'] });
+```
+
+Note that an empty string is also a value, and will be preserved:
+
+```javascript
+var withEmptyString = qs.parse('a[]=&a[]=b');
+assert.deepEqual(withEmptyString, { a: ['', 'b'] });
+
+var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
+assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
+```
+
+**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
+instead be converted to an object with the index as the key. This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array.
+
+```javascript
+var withMaxIndex = qs.parse('a[100]=b');
+assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
+```
+
+This limit can be overridden by passing an `arrayLimit` option:
+
+```javascript
+var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
+assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
+```
+
+To disable array parsing entirely, set `parseArrays` to `false`.
+
+```javascript
+var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
+assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
+```
+
+If you mix notations, **qs** will merge the two items into an object:
+
+```javascript
+var mixedNotation = qs.parse('a[0]=b&a[b]=c');
+assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
+```
+
+You can also create arrays of objects:
+
+```javascript
+var arraysOfObjects = qs.parse('a[][b]=c');
+assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
+```
+
+Some people use comma to join array, **qs** can parse it:
+```javascript
+var arraysOfObjects = qs.parse('a=b,c', { comma: true })
+assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] })
+```
+(_this cannot convert nested objects, such as `a={b:1},{c:d}`_)
+
+### Parsing primitive/scalar values (numbers, booleans, null, etc)
+
+By default, all values are parsed as strings. This behavior will not change and is explained in [issue #91](https://github.com/ljharb/qs/issues/91).
+
+```javascript
+var primitiveValues = qs.parse('a=15&b=true&c=null');
+assert.deepEqual(primitiveValues, { a: '15', b: 'true', c: 'null' });
+```
+
+If you wish to auto-convert values which look like numbers, booleans, and other values into their primitive counterparts, you can use the [query-types Express JS middleware](https://github.com/xpepermint/query-types) which will auto-convert all request query parameters.
+
+### Stringifying
+
+[](#preventEval)
+```javascript
+qs.stringify(object, [options]);
+```
+
+When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b' }), 'a=b');
+assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
+```
+
+This encoding can be disabled by setting the `encode` option to `false`:
+
+```javascript
+var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
+assert.equal(unencoded, 'a[b]=c');
+```
+
+Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
+```javascript
+var encodedValues = qs.stringify(
+    { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
+    { encodeValuesOnly: true }
+);
+assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
+```
+
+This encoding can also be replaced by a custom encoding method set as `encoder` option:
+
+```javascript
+var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
+    // Passed in values `a`, `b`, `c`
+    return // Return encoded string
+}})
+```
+
+_(Note: the `encoder` option does not apply if `encode` is `false`)_
+
+Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
+
+```javascript
+var decoded = qs.parse('x=z', { decoder: function (str) {
+    // Passed in values `x`, `z`
+    return // Return decoded string
+}})
+```
+
+You can encode keys and values using different logic by using the type argument provided to the encoder:
+
+```javascript
+var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str, defaultEncoder, charset, type) {
+    if (type === 'key') {
+        return // Encoded key
+    } else if (type === 'value') {
+        return // Encoded value
+    }
+}})
+```
+
+The type argument is also provided to the decoder:
+
+```javascript
+var decoded = qs.parse('x=z', { decoder: function (str, defaultDecoder, charset, type) {
+    if (type === 'key') {
+        return // Decoded key
+    } else if (type === 'value') {
+        return // Decoded value
+    }
+}})
+```
+
+Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
+
+When arrays are stringified, by default they are given explicit indices:
+
+```javascript
+qs.stringify({ a: ['b', 'c', 'd'] });
+// 'a[0]=b&a[1]=c&a[2]=d'
+```
+
+You may override this by setting the `indices` option to `false`:
+
+```javascript
+qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
+// 'a=b&a=c&a=d'
+```
+
+You may use the `arrayFormat` option to specify the format of the output array:
+
+```javascript
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
+// 'a[0]=b&a[1]=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
+// 'a[]=b&a[]=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
+// 'a=b&a=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' })
+// 'a=b,c'
+```
+
+When objects are stringified, by default they use bracket notation:
+
+```javascript
+qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
+// 'a[b][c]=d&a[b][e]=f'
+```
+
+You may override this to use dot notation by setting the `allowDots` option to `true`:
+
+```javascript
+qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
+// 'a.b.c=d&a.b.e=f'
+```
+
+Empty strings and null values will omit the value, but the equals sign (=) remains in place:
+
+```javascript
+assert.equal(qs.stringify({ a: '' }), 'a=');
+```
+
+Key with no values (such as an empty object or array) will return nothing:
+
+```javascript
+assert.equal(qs.stringify({ a: [] }), '');
+assert.equal(qs.stringify({ a: {} }), '');
+assert.equal(qs.stringify({ a: [{}] }), '');
+assert.equal(qs.stringify({ a: { b: []} }), '');
+assert.equal(qs.stringify({ a: { b: {}} }), '');
+```
+
+Properties that are set to `undefined` will be omitted entirely:
+
+```javascript
+assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
+```
+
+The query string may optionally be prepended with a question mark:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
+```
+
+The delimiter may be overridden with stringify as well:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
+```
+
+If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
+
+```javascript
+var date = new Date(7);
+assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
+assert.equal(
+    qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
+    'a=7'
+);
+```
+
+You may use the `sort` option to affect the order of parameter keys:
+
+```javascript
+function alphabeticalSort(a, b) {
+    return a.localeCompare(b);
+}
+assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
+```
+
+Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
+If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you
+pass an array, it will be used to select properties and array indices for stringification:
+
+```javascript
+function filterFunc(prefix, value) {
+    if (prefix == 'b') {
+        // Return an `undefined` value to omit a property.
+        return;
+    }
+    if (prefix == 'e[f]') {
+        return value.getTime();
+    }
+    if (prefix == 'e[g][0]') {
+        return value * 2;
+    }
+    return value;
+}
+qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
+// 'a=b&c=d&e[f]=123&e[g][0]=4'
+qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
+// 'a=b&e=f'
+qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
+// 'a[0]=b&a[2]=d'
+```
+
+### Handling of `null` values
+
+By default, `null` values are treated like empty strings:
+
+```javascript
+var withNull = qs.stringify({ a: null, b: '' });
+assert.equal(withNull, 'a=&b=');
+```
+
+Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings.
+
+```javascript
+var equalsInsensitive = qs.parse('a&b=');
+assert.deepEqual(equalsInsensitive, { a: '', b: '' });
+```
+
+To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
+values have no `=` sign:
+
+```javascript
+var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
+assert.equal(strictNull, 'a&b=');
+```
+
+To parse values without `=` back to `null` use the `strictNullHandling` flag:
+
+```javascript
+var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
+assert.deepEqual(parsedStrictNull, { a: null, b: '' });
+```
+
+To completely skip rendering keys with `null` values, use the `skipNulls` flag:
+
+```javascript
+var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
+assert.equal(nullsSkipped, 'a=b');
+```
+
+If you're communicating with legacy systems, you can switch to `iso-8859-1`
+using the `charset` option:
+
+```javascript
+var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' });
+assert.equal(iso, '%E6=%E6');
+```
+
+Characters that don't exist in `iso-8859-1` will be converted to numeric
+entities, similar to what browsers do:
+
+```javascript
+var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' });
+assert.equal(numeric, 'a=%26%239786%3B');
+```
+
+You can use the `charsetSentinel` option to announce the character by
+including an `utf8=✓` parameter with the proper encoding if the checkmark,
+similar to what Ruby on Rails and others do when submitting forms.
+
+```javascript
+var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true });
+assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA');

+
+### Dealing with special character sets
+
+By default the encoding and decoding of characters is done in `utf-8`,
+and `iso-8859-1` support is also built in via the `charset` parameter.
+
+If you wish to encode querystrings to a different character set (i.e.
+[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
+[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
+
+```javascript
+var encoder = require('qs-iconv/encoder')('shift_jis');
+var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
+assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
+```
+
+This also works for decoding of query strings:
+
+```javascript
+var decoder = require('qs-iconv/decoder')('shift_jis');
+var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
+assert.deepEqual(obj, { a: 'こんにちは！' });
+```
+
+### RFC 3986 and RFC 1738 space encoding
+
+RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
+In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
+
+```
+assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c');
+assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c');
+assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
+```

+
+Range header field parser.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install range-parser
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var parseRange = require('range-parser')
+```
+
+### parseRange(size, header, options)
+
+Parse the given `header` string where `size` is the maximum size of the resource.
+An array of ranges will be returned or negative numbers indicating an error parsing.
+
+  * `-2` signals a malformed header string
+  * `-1` signals an unsatisfiable range
+
+<!-- eslint-disable no-undef -->
+
+```js
+// parse header from request
+var range = parseRange(size, req.headers.range)
+
+// the type of the range
+if (range.type === 'bytes') {
+  // the ranges
+  range.forEach(function (r) {
+    // do something with r.start and r.end
+  })
+}
+```
+
+#### Options
+
+These properties are accepted in the options object.
+
+##### combine
+
+Specifies if overlapping & adjacent ranges should be combined, defaults to `false`.
+When `true`, ranges will be combined and returned as if they were specified that
+way in the header.
+
+<!-- eslint-disable no-undef -->
+
+```js
+parseRange(100, 'bytes=50-55,0-10,5-10,56-60', { combine: true })
+// => [
+//      { start: 0,  end: 10 },
+//      { start: 50, end: 60 }
+//    ]
+```

+
+Gets the entire buffer of a stream either as a `Buffer` or a string.
+Validates the stream's length against an expected length and maximum limit.
+Ideal for parsing request bodies.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install raw-body
+```
+
+### TypeScript
+
+This module includes a [TypeScript](https://www.typescriptlang.org/)
+declaration file to enable auto complete in compatible editors and type
+information for TypeScript projects. This module depends on the Node.js
+types, so install `@types/node`:
+
+```sh
+$ npm install @types/node
+```
+
+## API
+
+```js
+var getRawBody = require('raw-body')
+```
+
+### getRawBody(stream, [options], [callback])
+
+**Returns a promise if no callback specified and global `Promise` exists.**
+
+Options:
+
+- `length` - The length of the stream.
+  If the contents of the stream do not add up to this length,
+  an `400` error code is returned.
+- `limit` - The byte limit of the body.
+  This is the number of bytes or any string format supported by
+  [bytes](https://www.npmjs.com/package/bytes),
+  for example `1000`, `'500kb'` or `'3mb'`.
+  If the body ends up being larger than this limit,
+  a `413` error code is returned.
+- `encoding` - The encoding to use to decode the body into a string.
+  By default, a `Buffer` instance will be returned when no encoding is specified.
+  Most likely, you want `utf-8`, so setting `encoding` to `true` will decode as `utf-8`.
+  You can use any type of encoding supported by [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme).
+
+You can also pass a string in place of options to just specify the encoding.
+
+If an error occurs, the stream will be paused, everything unpiped,
+and you are responsible for correctly disposing the stream.
+For HTTP requests, you may need to finish consuming the stream if
+you want to keep the socket open for future requests. For streams
+that use file descriptors, you should `stream.destroy()` or
+`stream.close()` to prevent leaks.
+
+## Errors
+
+This module creates errors depending on the error condition during reading.
+The error may be an error from the underlying Node.js implementation, but is
+otherwise an error created by this module, which has the following attributes:
+
+  * `limit` - the limit in bytes
+  * `length` and `expected` - the expected length of the stream
+  * `received` - the received bytes
+  * `encoding` - the invalid encoding
+  * `status` and `statusCode` - the corresponding status code for the error
+  * `type` - the error type
+
+### Types
+
+The errors from this module have a `type` property which allows for the programmatic
+determination of the type of error returned.
+
+#### encoding.unsupported
+
+This error will occur when the `encoding` option is specified, but the value does
+not map to an encoding supported by the [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme)
+module.
+
+#### entity.too.large
+
+This error will occur when the `limit` option is specified, but the stream has
+an entity that is larger.
+
+#### request.aborted
+
+This error will occur when the request stream is aborted by the client before
+reading the body has finished.
+
+#### request.size.invalid
+
+This error will occur when the `length` option is specified, but the stream has
+emitted more bytes.
+
+#### stream.encoding.set
+
+This error will occur when the given stream has an encoding set on it, making it
+a decoded stream. The stream should not have an encoding set and is expected to
+emit `Buffer` objects.
+
+#### stream.not.readable
+
+This error will occur when the given stream is not readable.
+
+## Examples
+
+### Simple Express example
+
+```js
+var contentType = require('content-type')
+var express = require('express')
+var getRawBody = require('raw-body')
+
+var app = express()
+
+app.use(function (req, res, next) {
+  getRawBody(req, {
+    length: req.headers['content-length'],
+    limit: '1mb',
+    encoding: contentType.parse(req).parameters.charset
+  }, function (err, string) {
+    if (err) return next(err)
+    req.text = string
+    next()
+  })
+})
+
+// now access req.text
+```
+
+### Simple Koa example
+
+```js
+var contentType = require('content-type')
+var getRawBody = require('raw-body')
+var koa = require('koa')
+
+var app = koa()
+
+app.use(function * (next) {
+  this.text = yield getRawBody(this.req, {
+    length: this.req.headers['content-length'],
+    limit: '1mb',
+    encoding: contentType.parse(this.req).parameters.charset
+  })
+  yield next
+})
+
+// now access this.text
+```
+
+### Using as a promise
+
+To use this library as a promise, simply omit the `callback` and a promise is
+returned, provided that a global `Promise` is defined.
+
+```js
+var getRawBody = require('raw-body')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  getRawBody(req)
+    .then(function (buf) {
+      res.statusCode = 200
+      res.end(buf.length + ' bytes submitted')
+    })
+    .catch(function (err) {
+      res.statusCode = 500
+      res.end(err.message)
+    })
+})
+
+server.listen(3000)
+```
+
+### Using with TypeScript
+
+```ts
+import * as getRawBody from 'raw-body';
+import * as http from 'http';
+
+const server = http.createServer((req, res) => {
+  getRawBody(req)
+  .then((buf) => {
+    res.statusCode = 200;
+    res.end(buf.length + ' bytes submitted');
+  })
+  .catch((err) => {
+    res.statusCode = err.statusCode;
+    res.end(err.message);
+  });
+});
+
+server.listen(3000);
+```

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited.  There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting.  This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions.  If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer.  If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus.  See
+"WG Membership" above.

+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.

+## Links
+
+* **Google Hangouts Video**: http://www.youtube.com/watch?v=I9nDOSGfwZg
+* **GitHub Issue**: https://github.com/iojs/readable-stream/issues/106
+* **Original Minutes Google Doc**: https://docs.google.com/document/d/17aTgLnjMXIrfjgNaTUnHQO7m3xgzHR2VXBTmi03Qii4/
+
+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+  but, we lose the opportunity to change the model
+  may not be backwards incompatible (double check keys)
+
+  **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third state”
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third state”
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+  * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data” approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+

+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+

+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+# Porting to the Buffer.from/Buffer.alloc API
+
+<a id="overview"></a>
+## Overview
+
+- [Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.](#variant-1) (*recommended*)
+- [Variant 2: Use a polyfill](#variant-2)
+- [Variant 3: manual detection, with safeguards](#variant-3)
+
+### Finding problematic bits of code using grep
+
+Just run `grep -nrE '[^a-zA-Z](Slow)?Buffer\s*\(' --exclude-dir node_modules`.
+
+It will find all the potentially unsafe places in your own code (with some considerably unlikely
+exceptions).
+
+### Finding problematic bits of code using Node.js 8
+
+If you’re using Node.js ≥ 8.0.0 (which is recommended), Node.js exposes multiple options that help with finding the relevant pieces of code:
+
+- `--trace-warnings` will make Node.js show a stack trace for this warning and other warnings that are printed by Node.js.
+- `--trace-deprecation` does the same thing, but only for deprecation warnings.
+- `--pending-deprecation` will show more types of deprecation warnings. In particular, it will show the `Buffer()` deprecation warning, even on Node.js 8.
+
+You can set these flags using an environment variable:
+
+```console
+$ export NODE_OPTIONS='--trace-warnings --pending-deprecation'
+$ cat example.js
+'use strict';
+const foo = new Buffer('foo');
+$ node example.js
+(node:7147) [DEP0005] DeprecationWarning: The Buffer() and new Buffer() constructors are not recommended for use due to security and usability concerns. Please use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() construction methods instead.
+    at showFlaggedDeprecation (buffer.js:127:13)
+    at new Buffer (buffer.js:148:3)
+    at Object.<anonymous> (/path/to/example.js:2:13)
+    [... more stack trace lines ...]
+```
+
+### Finding problematic bits of code using linters
+
+Eslint rules [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
+or
+[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
+also find calls to deprecated `Buffer()` API. Those rules are included in some pre-sets.
+
+There is a drawback, though, that it doesn't always
+[work correctly](https://github.com/chalker/safer-buffer#why-not-safe-buffer) when `Buffer` is
+overriden e.g. with a polyfill, so recommended is a combination of this and some other method
+described above.
+
+<a id="variant-1"></a>
+## Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.
+
+This is the recommended solution nowadays that would imply only minimal overhead.
+
+The Node.js 5.x release line has been unsupported since July 2016, and the Node.js 4.x release line reaches its End of Life in April 2018 (→ [Schedule](https://github.com/nodejs/Release#release-schedule)). This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible.
+
+What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way:
+
+- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`.
+- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`).
+- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`.
+
+Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than
+`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling.
+
+Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
+or
+[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
+is recommended to avoid accidential unsafe Buffer API usage.
+
+There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005)
+for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`.
+Note that it currently only works with cases where the arguments are literals or where the
+constructor is invoked with two arguments.
+
+_If you currently support those older Node.js versions and dropping them would be a semver-major change
+for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2)
+or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive
+the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and
+your users will not observe a runtime deprecation warning when running your code on Node.js 10._
+
+<a id="variant-2"></a>
+## Variant 2: Use a polyfill
+
+Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older
+Node.js versions.
+
+You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill
+`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api.
+
+Make sure that you do not use old `new Buffer` API — in any files where the line above is added,
+using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though.
+
+Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or
+[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) —
+those are great, the only downsides being 4 deps in the tree and slightly more code changes to
+migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only
+`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies.
+
+_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also
+provides a polyfill, but takes a different approach which has
+[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you
+to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as
+it is problematic, can cause issues in your code, and will start emitting runtime deprecation
+warnings starting with Node.js 10._
+
+Note that in either case, it is important that you also remove all calls to the old Buffer
+API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides
+a polyfill for the new API. I have seen people doing that mistake.
+
+Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
+or
+[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
+is recommended.
+
+_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._

+## Variant 3 — manual detection, with safeguards
+
+This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own
+wrapper around them.
+
+### Buffer(0)
+
+This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which
+returns the same result all the way down to Node.js 0.8.x.
+
+### Buffer(notNumber)
+
+Before:
+
+```js
+var buf = new Buffer(notNumber, encoding);
+```
+
+After:
+
+```js
+var buf;
+if (Buffer.from && Buffer.from !== Uint8Array.from) {
+  buf = Buffer.from(notNumber, encoding);
+} else {
+  if (typeof notNumber === 'number')
+    throw new Error('The "size" argument must be of type number.');
+  buf = new Buffer(notNumber, encoding);
+}
+```
+
+`encoding` is optional.
+
+Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not
+hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the
+Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous
+security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create
+problems ranging from DoS to leaking sensitive information to the attacker from the process memory.
+
+When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can
+be omitted.
+
+Also note that using TypeScript does not fix this problem for you — when libs written in
+`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as
+all type checks are translation-time only and are not present in the actual JS code which TS
+compiles to.
+
+### Buffer(number)
+
+For Node.js 0.10.x (and below) support:
+
+```js
+var buf;
+if (Buffer.alloc) {
+  buf = Buffer.alloc(number);
+} else {
+  buf = new Buffer(number);
+  buf.fill(0);
+}
+```
+
+Otherwise (Node.js ≥ 0.12.x):
+
+```js
+const buf = Buffer.alloc ? Buffer.alloc(number) : new Buffer(number).fill(0);
+```
+
+## Regarding Buffer.allocUnsafe
+
+Be extra cautious when using `Buffer.allocUnsafe`:
+ * Don't use it if you don't have a good reason to
+   * e.g. you probably won't ever see a performance difference for small buffers, in fact, those
+     might be even faster with `Buffer.alloc()`,
+   * if your code is not in the hot code path — you also probably won't notice a difference,
+   * keep in mind that zero-filling minimizes the potential risks.
+ * If you use it, make sure that you never return the buffer in a partially-filled state,
+   * if you are writing to it sequentially — always truncate it to the actuall written length
+
+Errors in handling buffers allocated with `Buffer.allocUnsafe` could result in various issues,
+ranged from undefined behaviour of your code to sensitive data (user input, passwords, certs)
+leaking to the remote attacker.
+
+_Note that the same applies to `new Buffer` usage without zero-filling, depending on the Node.js
+version (and lacking type checks also adds DoS to the list of potential problems)._

+## FAQ
+
+<a id="design-flaws"></a>
+### What is wrong with the `Buffer` constructor?
+
+The `Buffer` constructor could be used to create a buffer in many different ways:
+
+- `new Buffer(42)` creates a `Buffer` of 42 bytes. Before Node.js 8, this buffer contained
+  *arbitrary memory* for performance reasons, which could include anything ranging from
+  program source code to passwords and encryption keys.
+- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of
+  the string `'abc'`. A second argument could specify another encoding: For example,
+  `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original
+  sequence of bytes that it represents.
+- There are several other combinations of arguments.
+
+This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell
+what exactly the contents of the generated buffer are* without knowing the type of `foo`.
+
+Sometimes, the value of `foo` comes from an external source. For example, this function
+could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form:
+
+```
+function stringToBase64(req, res) {
+  // The request body should have the format of `{ string: 'foobar' }`
+  const rawBytes = new Buffer(req.body.string)
+  const encoded = rawBytes.toString('base64')
+  res.end({ encoded: encoded })
+}
+```
+
+Note that this code does *not* validate the type of `req.body.string`:
+
+- `req.body.string` is expected to be a string. If this is the case, all goes well.
+- `req.body.string` is controlled by the client that sends the request.
+- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes:
+  - Before Node.js 8, the content would be uninitialized
+  - After Node.js 8, the content would be `50` bytes with the value `0`
+
+Because of the missing type check, an attacker could intentionally send a number
+as part of the request. Using this, they can either:
+
+- Read uninitialized memory. This **will** leak passwords, encryption keys and other
+  kinds of sensitive information. (Information leak)
+- Force the program to allocate a large amount of memory. For example, when specifying
+  `500000000` as the input value, each request will allocate 500MB of memory.
+  This can be used to either exhaust the memory available of a program completely
+  and make it crash, or slow it down significantly. (Denial of Service)
+
+Both of these scenarios are considered serious security issues in a real-world
+web server context.
+
+when using `Buffer.from(req.body.string)` instead, passing a number will always
+throw an exception instead, giving a controlled behaviour that can always be
+handled by the program.

+### The `Buffer()` constructor has been deprecated for a while. Is this really an issue?
+
+Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still
+widely used. This includes new code, and overall usage of such code has actually been
+*increasing*.

+
+Modern Buffer API polyfill without footguns, working on Node.js from 0.8 to current.
+
+## How to use?
+
+First, port all `Buffer()` and `new Buffer()` calls to `Buffer.alloc()` and `Buffer.from()` API.
+
+Then, to achieve compatibility with outdated Node.js versions (`<4.5.0` and 5.x `<5.9.0`), use
+`const Buffer = require('safer-buffer').Buffer` in all files where you make calls to the new
+Buffer API. _Use `var` instead of `const` if you need that for your Node.js version range support._
+
+Also, see the
+[porting Buffer](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md) guide.
+
+## Do I need it?
+
+Hopefully, not — dropping support for outdated Node.js versions should be fine nowdays, and that
+is the recommended path forward. You _do_ need to port to the `Buffer.alloc()` and `Buffer.from()`
+though.
+
+See the [porting guide](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md)
+for a better description.
+
+## Why not [safe-buffer](https://npmjs.com/safe-buffer)?
+
+_In short: while `safe-buffer` serves as a polyfill for the new API, it allows old API usage and
+itself contains footguns._
+
+`safe-buffer` could be used safely to get the new API while still keeping support for older
+Node.js versions (like this module), but while analyzing ecosystem usage of the old Buffer API
+I found out that `safe-buffer` is itself causing problems in some cases.
+
+For example, consider the following snippet:
+
+```console
+$ cat example.unsafe.js
+console.log(Buffer(20))
+$ ./node-v6.13.0-linux-x64/bin/node example.unsafe.js
+<Buffer 0a 00 00 00 00 00 00 00 28 13 de 02 00 00 00 00 05 00 00 00>
+$ standard example.unsafe.js
+standard: Use JavaScript Standard Style (https://standardjs.com)
+  /home/chalker/repo/safer-buffer/example.unsafe.js:2:13: 'Buffer()' was deprecated since v6. Use 'Buffer.alloc()' or 'Buffer.from()' (use 'https://www.npmjs.com/package/safe-buffer' for '<4.5.0') instead.
+```
+
+This is allocates and writes to console an uninitialized chunk of memory.
+[standard](https://www.npmjs.com/package/standard) linter (among others) catch that and warn people
+to avoid using unsafe API.
+
+Let's now throw in `safe-buffer`!
+
+```console
+$ cat example.safe-buffer.js
+const Buffer = require('safe-buffer').Buffer
+console.log(Buffer(20))
+$ standard example.safe-buffer.js
+$ ./node-v6.13.0-linux-x64/bin/node example.safe-buffer.js
+<Buffer 08 00 00 00 00 00 00 00 28 58 01 82 fe 7f 00 00 00 00 00 00>
+```
+
+See the problem? Adding in `safe-buffer` _magically removes the lint warning_, but the behavior
+remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out
+chunks of uninitialized memory.
+_And this code will still emit runtime warnings on Node.js 10.x and above._
+
+That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or
+emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some
+discussion, it was decided to move my approach into a separate package, and _this is that separate
+package_.
+
+This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing,
+«fixing» the lint warning by blindly including `safe-buffer` without any actual changes.
+
+Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request
+can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go
+unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even
+pass CI. _I also observed that being done in popular packages._
+
+Some examples:
+ * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31)
+   (a module with 548 759 downloads/month),
+ * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61)
+   (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)),
+ * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c)
+   (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)),
+ * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec)
+   (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)),
+ * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1)
+   (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)).
+ * And there are a lot more over the ecosystem.
+
+I filed a PR at
+[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to
+partially fix that (for cases when that lint rule is used), but it is a semver-major change for
+linter rules and presets, so it would take significant time for that to reach actual setups.
+_It also hasn't been released yet (2018-03-20)._
+
+Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake.
+It still supports it with an explicit concern barier, by placing it under
+`require('safer-buffer/dangereous')`.
+
+## But isn't throwing bad?
+
+Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like
+unguarded `new Buffer()` calls that end up receiving user input can do.
+
+This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so
+it is really simple to keep track of things and make sure that you don't mix old API usage with that.
+Also, CI should hint anything that you might have missed.
+
+New commits, if tested, won't land new usage of unsafe Buffer API this way.
+_Node.js 10.x also deals with that by printing a runtime depecation warning._
+
+### Would it affect third-party modules?
+
+No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`.
+Don't do that.
+
+### But I don't want throwing…
+
+That is also fine!
+
+Also, it could be better in some cases when you don't comprehensive enough test coverage.
+
+In that case — just don't override `Buffer` and use
+`var SaferBuffer = require('safer-buffer').Buffer` instead.
+
+That way, everything using `Buffer` natively would still work, but there would be two drawbacks:
+
+* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and
+  `SaferBuffer.alloc` instead.
+* You are still open to accidentally using the insecure deprecated API — use a linter to catch that.
+
+Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly
+recommended. `Buffer` is not overriden in this usecase, so linters won't get confused.
+
+## «Without footguns»?
+
+Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property
+on older versions and duping things from there. You shouldn't do that in your code, probabably.
+
+The intention is to remove the most significant footguns that affect lots of packages in the
+ecosystem, and to do it in the proper way.
+
+Also, this package doesn't protect against security issues affecting some Node.js versions, so for
+usage in your own production code, it is still recommended to update to a Node.js version
+[supported by upstream](https://github.com/nodejs/release#release-schedule).

+
+Send is a library for streaming files from the file system as a http response
+supporting partial responses (Ranges), conditional-GET negotiation (If-Match,
+If-Unmodified-Since, If-None-Match, If-Modified-Since), high test coverage,
+and granular events which may be leveraged to take appropriate actions in your
+application or framework.
+
+Looking to serve up entire folders mapped to URLs? Try [serve-static](https://www.npmjs.org/package/serve-static).
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install send
+```
+
+## API
+
+```js
+var send = require('send')
+```
+
+### send(req, path, [options])
+
+Create a new `SendStream` for the given path to send to a `res`. The `req` is
+the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded,
+not the actual file-system path).
+
+#### Options
+
+##### acceptRanges
+
+Enable or disable accepting ranged requests, defaults to true.
+Disabling this will not send `Accept-Ranges` and ignore the contents
+of the `Range` request header.
+
+##### cacheControl
+
+Enable or disable setting `Cache-Control` response header, defaults to
+true. Disabling this will ignore the `immutable` and `maxAge` options.
+
+##### dotfiles
+
+Set how "dotfiles" are treated when encountered. A dotfile is a file
+or directory that begins with a dot ("."). Note this check is done on
+the path itself without checking if the path actually exists on the
+disk. If `root` is specified, only the dotfiles above the root are
+checked (i.e. the root itself can be within a dotfile when when set
+to "deny").
+
+  - `'allow'` No special treatment for dotfiles.
+  - `'deny'` Send a 403 for any request for a dotfile.
+  - `'ignore'` Pretend like the dotfile does not exist and 404.
+
+The default value is _similar_ to `'ignore'`, with the exception that
+this default will not ignore the files within a directory that begins
+with a dot, for backward-compatibility.
+
+##### end
+
+Byte offset at which the stream ends, defaults to the length of the file
+minus 1. The end is inclusive in the stream, meaning `end: 3` will include
+the 4th byte in the stream.
+
+##### etag
+
+Enable or disable etag generation, defaults to true.
+
+##### extensions
+
+If a given file doesn't exist, try appending one of the given extensions,
+in the given order. By default, this is disabled (set to `false`). An
+example value that will serve extension-less HTML files: `['html', 'htm']`.
+This is skipped if the requested file already has an extension.
+
+##### immutable
+
+Enable or disable the `immutable` directive in the `Cache-Control` response
+header, defaults to `false`. If set to `true`, the `maxAge` option should
+also be specified to enable caching. The `immutable` directive will prevent
+supported clients from making conditional requests during the life of the
+`maxAge` option to check if the file has changed.
+
+##### index
+
+By default send supports "index.html" files, to disable this
+set `false` or to supply a new index pass a string or an array
+in preferred order.
+
+##### lastModified
+
+Enable or disable `Last-Modified` header, defaults to true. Uses the file
+system's last modified value.
+
+##### maxAge
+
+Provide a max-age in milliseconds for http caching, defaults to 0.
+This can also be a string accepted by the
+[ms](https://www.npmjs.org/package/ms#readme) module.
+
+##### root
+
+Serve files relative to `path`.
+
+##### start
+
+Byte offset at which the stream starts, defaults to 0. The start is inclusive,
+meaning `start: 2` will include the 3rd byte in the stream.
+
+#### Events
+
+The `SendStream` is an event emitter and will emit the following events:
+
+  - `error` an error occurred `(err)`
+  - `directory` a directory was requested `(res, path)`
+  - `file` a file was requested `(path, stat)`
+  - `headers` the headers are about to be set on a file `(res, path, stat)`
+  - `stream` file streaming has started `(stream)`
+  - `end` streaming has completed
+
+#### .pipe
+
+The `pipe` method is used to pipe the response into the Node.js HTTP response
+object, typically `send(req, path, options).pipe(res)`.
+
+### .mime
+
+The `mime` export is the global instance of of the
+[`mime` npm module](https://www.npmjs.com/package/mime).
+
+This is used to configure the MIME types that are associated with file extensions
+as well as other options for how to resolve the MIME type of a file (like the
+default type to use for an unknown file extension).
+
+## Error-handling
+
+By default when no `error` listeners are present an automatic response will be
+made, otherwise you have full control over the response, aka you may show a 5xx
+page etc.
+
+## Caching
+
+It does _not_ perform internal caching, you should use a reverse proxy cache
+such as Varnish for this, or those fancy things called CDNs. If your
+application is small enough that it would benefit from single-node memory
+caching, it's small enough that it does not need caching at all ;).
+
+## Debugging
+
+To enable `debug()` instrumentation output export __DEBUG__:
+
+```
+$ DEBUG=send node app
+```
+
+## Running tests
+
+```
+$ npm install
+$ npm test
+```
+
+## Examples
+
+### Serve a specific file
+
+This simple example will send a specific file to all requests.
+
+```js
+var http = require('http')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, '/path/to/index.html')
+    .pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Serve all files from a directory
+
+This simple example will just serve up all the files in a
+given directory as the top-level. For example, a request
+`GET /foo.txt` will send back `/www/public/foo.txt`.
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, { root: '/www/public' })
+    .pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Custom file types
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+// Default unknown types to text/plain
+send.mime.default_type = 'text/plain'
+
+// Add a custom type
+send.mime.define({
+  'application/x-my-type': ['x-mt', 'x-mtt']
+})
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, { root: '/www/public' })
+    .pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Custom directory index view
+
+This is a example of serving up a structure of directories with a
+custom function to render a listing of a directory.
+
+```js
+var http = require('http')
+var fs = require('fs')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+// Transfer arbitrary files from within /www/example.com/public/*
+// with a custom handler for directory listing
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, { index: false, root: '/www/public' })
+    .once('directory', directory)
+    .pipe(res)
+})
+
+server.listen(3000)
+
+// Custom directory handler
+function directory (res, path) {
+  var stream = this
+
+  // redirect to trailing slash for consistent url
+  if (!stream.hasTrailingSlash()) {
+    return stream.redirect(path)
+  }
+
+  // get directory list
+  fs.readdir(path, function onReaddir (err, list) {
+    if (err) return stream.error(err)
+
+    // render an index for the directory
+    res.setHeader('Content-Type', 'text/plain; charset=UTF-8')
+    res.end(list.join('\n') + '\n')
+  })
+}
+```
+
+### Serving from a root directory with custom error-handling
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  // your custom error-handling logic:
+  function error (err) {
+    res.statusCode = err.status || 500
+    res.end(err.message)
+  }
+
+  // your custom headers
+  function headers (res, path, stat) {
+    // serve all files for download
+    res.setHeader('Content-Disposition', 'attachment')
+  }
+
+  // your custom directory handling logic:
+  function redirect () {
+    res.statusCode = 301
+    res.setHeader('Location', req.url + '/')
+    res.end('Redirecting to ' + req.url + '/')
+  }
+
+  // transfer arbitrary files from within
+  // /www/example.com/public/*
+  send(req, parseUrl(req).pathname, { root: '/www/public' })
+    .on('error', error)
+    .on('directory', redirect)
+    .on('headers', headers)
+    .pipe(res)
+})
+
+server.listen(3000)
+```

+# ms
+
+![CI](https://github.com/vercel/ms/workflows/CI/badge.svg)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+ms('-3 days') // -259200000
+ms('-1h')     // -3600000
+ms('-200')    // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(-3 * 60000)        // "-3m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(-3 * 60000, { long: true })        // "-3 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install serve-static
+```
+
+## API
+
+```js
+var serveStatic = require('serve-static')
+```
+
+### serveStatic(root, options)
+
+Create a new middleware function to serve files from within a given root
+directory. The file to serve will be determined by combining `req.url`
+with the provided root directory. When a file is not found, instead of
+sending a 404 response, this module will instead call `next()` to move on
+to the next middleware, allowing for stacking and fall-backs.
+
+#### Options
+
+##### acceptRanges
+
+Enable or disable accepting ranged requests, defaults to true.
+Disabling this will not send `Accept-Ranges` and ignore the contents
+of the `Range` request header.
+
+##### cacheControl
+
+Enable or disable setting `Cache-Control` response header, defaults to
+true. Disabling this will ignore the `immutable` and `maxAge` options.
+
+##### dotfiles
+
+ Set how "dotfiles" are treated when encountered. A dotfile is a file
+or directory that begins with a dot ("."). Note this check is done on
+the path itself without checking if the path actually exists on the
+disk. If `root` is specified, only the dotfiles above the root are
+checked (i.e. the root itself can be within a dotfile when set
+to "deny").
+
+  - `'allow'` No special treatment for dotfiles.
+  - `'deny'` Deny a request for a dotfile and 403/`next()`.
+  - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`.
+
+The default value is similar to `'ignore'`, with the exception that this
+default will not ignore the files within a directory that begins with a dot.
+
+##### etag
+
+Enable or disable etag generation, defaults to true.
+
+##### extensions
+
+Set file extension fallbacks. When set, if a file is not found, the given
+extensions will be added to the file name and search for. The first that
+exists will be served. Example: `['html', 'htm']`.
+
+The default value is `false`.
+
+##### fallthrough
+
+Set the middleware to have client errors fall-through as just unhandled
+requests, otherwise forward a client error. The difference is that client
+errors like a bad request or a request to a non-existent file will cause
+this middleware to simply `next()` to your next middleware when this value
+is `true`. When this value is `false`, these errors (even 404s), will invoke
+`next(err)`.
+
+Typically `true` is desired such that multiple physical directories can be
+mapped to the same web address or for routes to fill in non-existent files.
+
+The value `false` can be used if this middleware is mounted at a path that
+is designed to be strictly a single file system directory, which allows for
+short-circuiting 404s for less overhead. This middleware will also reply to
+all methods.
+
+The default value is `true`.
+
+##### immutable
+
+Enable or disable the `immutable` directive in the `Cache-Control` response
+header, defaults to `false`. If set to `true`, the `maxAge` option should
+also be specified to enable caching. The `immutable` directive will prevent
+supported clients from making conditional requests during the life of the
+`maxAge` option to check if the file has changed.
+
+##### index
+
+By default this module will send "index.html" files in response to a request
+on a directory. To disable this set `false` or to supply a new index pass a
+string or an array in preferred order.
+
+##### lastModified
+
+Enable or disable `Last-Modified` header, defaults to true. Uses the file
+system's last modified value.
+
+##### maxAge
+
+Provide a max-age in milliseconds for http caching, defaults to 0. This
+can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
+module.
+
+##### redirect
+
+Redirect to trailing "/" when the pathname is a dir. Defaults to `true`.
+
+##### setHeaders
+
+Function to set custom headers on response. Alterations to the headers need to
+occur synchronously. The function is called as `fn(res, path, stat)`, where
+the arguments are:
+
+  - `res` the response object
+  - `path` the file path that is being sent
+  - `stat` the stat object of the file that is being sent
+
+## Examples
+
+### Serve files with vanilla node.js http server
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+// Serve up public/ftp folder
+var serve = serveStatic('public/ftp', { index: ['index.html', 'index.htm'] })
+
+// Create server
+var server = http.createServer(function onRequest (req, res) {
+  serve(req, res, finalhandler(req, res))
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serve all files as downloads
+
+```js
+var contentDisposition = require('content-disposition')
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+// Serve up public/ftp folder
+var serve = serveStatic('public/ftp', {
+  index: false,
+  setHeaders: setHeaders
+})
+
+// Set header to force download
+function setHeaders (res, path) {
+  res.setHeader('Content-Disposition', contentDisposition(path))
+}
+
+// Create server
+var server = http.createServer(function onRequest (req, res) {
+  serve(req, res, finalhandler(req, res))
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serving using express
+
+#### Simple
+
+This is a simple example of using Express.
+
+```js
+var express = require('express')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic('public/ftp', { index: ['default.html', 'default.htm'] }))
+app.listen(3000)
+```
+
+#### Multiple roots
+
+This example shows a simple way to search through multiple directories.
+Files are searched for in `public-optimized/` first, then `public/` second
+as a fallback.
+
+```js
+var express = require('express')
+var path = require('path')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic(path.join(__dirname, 'public-optimized')))
+app.use(serveStatic(path.join(__dirname, 'public')))
+app.listen(3000)
+```
+
+#### Different settings for paths
+
+This example shows how to set a different max age depending on the served
+file type. In this example, HTML files are not cached, while everything else
+is for 1 day.
+
+```js
+var express = require('express')
+var path = require('path')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic(path.join(__dirname, 'public'), {
+  maxAge: '1d',
+  setHeaders: setCustomCacheControl
+}))
+
+app.listen(3000)
+
+function setCustomCacheControl (res, path) {
+  if (serveStatic.mime.lookup(path) === 'text/html') {
+    // Custom Cache-Control for HTML files
+    res.setHeader('Cache-Control', 'public, max-age=0')
+  }
+}
+```

+# Polyfill for `Object.setPrototypeOf`
+
+[![NPM Version](https://img.shields.io/npm/v/setprototypeof.svg)](https://npmjs.org/package/setprototypeof)
+[![NPM Downloads](https://img.shields.io/npm/dm/setprototypeof.svg)](https://npmjs.org/package/setprototypeof)
+[![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg)](https://github.com/standard/standard)
+
+A simple cross platform implementation to set the prototype of an instianted object.  Supports all modern browsers and at least back to IE8.
+
+## Usage:
+
+```
+$ npm install --save setprototypeof
+```
+
+```javascript
+var setPrototypeOf = require('setprototypeof')
+
+var obj = {}
+setPrototypeOf(obj, {
+  foo: function () {
+    return 'bar'
+  }
+})
+obj.foo() // bar
+```
+
+TypeScript is also supported:
+
+```typescript

+
+Simple SQL escape and format for MySQL
+
+## Install
+
+```sh
+$ npm install sqlstring
+```
+
+## Usage
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var SqlString = require('sqlstring');
+```
+
+### Escaping query values
+
+**Caution** These methods of escaping values only works when the
+[NO_BACKSLASH_ESCAPES](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_no_backslash_escapes)
+SQL mode is disabled (which is the default state for MySQL servers).
+
+In order to avoid SQL Injection attacks, you should always escape any user
+provided data before using it inside a SQL query. You can do so using the
+`SqlString.escape()` method:
+
+```js
+var userId = 'some user provided value';
+var sql    = 'SELECT * FROM users WHERE id = ' + SqlString.escape(userId);
+console.log(sql); // SELECT * FROM users WHERE id = 'some user provided value'
+```
+
+Alternatively, you can use `?` characters as placeholders for values you would
+like to have escaped like this:
+
+```js
+var userId = 1;
+var sql    = SqlString.format('SELECT * FROM users WHERE id = ?', [userId]);
+console.log(sql); // SELECT * FROM users WHERE id = 1
+```
+
+Multiple placeholders are mapped to values in the same order as passed. For example,
+in the following query `foo` equals `a`, `bar` equals `b`, `baz` equals `c`, and
+`id` will be `userId`:
+
+```js
+var userId = 1;
+var sql    = SqlString.format('UPDATE users SET foo = ?, bar = ?, baz = ? WHERE id = ?',
+  ['a', 'b', 'c', userId]);
+console.log(sql); // UPDATE users SET foo = 'a', bar = 'b', baz = 'c' WHERE id = 1
+```
+
+This looks similar to prepared statements in MySQL, however it really just uses
+the same `SqlString.escape()` method internally.
+
+**Caution** This also differs from prepared statements in that all `?` are
+replaced, even those contained in comments and strings.
+
+Different value types are escaped differently, here is how:
+
+* Numbers are left untouched
+* Booleans are converted to `true` / `false`
+* Date objects are converted to `'YYYY-mm-dd HH:ii:ss'` strings
+* Buffers are converted to hex strings, e.g. `X'0fa5'`
+* Strings are safely escaped
+* Arrays are turned into list, e.g. `['a', 'b']` turns into `'a', 'b'`
+* Nested arrays are turned into grouped lists (for bulk inserts), e.g. `[['a',
+  'b'], ['c', 'd']]` turns into `('a', 'b'), ('c', 'd')`
+* Objects that have a `toSqlString` method will have `.toSqlString()` called
+  and the returned value is used as the raw SQL.
+* Objects are turned into `key = 'val'` pairs for each enumerable property on
+  the object. If the property's value is a function, it is skipped; if the
+  property's value is an object, toString() is called on it and the returned
+  value is used.
+* `undefined` / `null` are converted to `NULL`
+* `NaN` / `Infinity` are left as-is. MySQL does not support these, and trying
+  to insert them as values will trigger MySQL errors until they implement
+  support.
+
+You may have noticed that this escaping allows you to do neat things like this:
+
+```js
+var post  = {id: 1, title: 'Hello MySQL'};
+var sql = SqlString.format('INSERT INTO posts SET ?', post);
+console.log(sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
+```
+
+And the `toSqlString` method allows you to form complex queries with functions:
+
+```js
+var CURRENT_TIMESTAMP = { toSqlString: function() { return 'CURRENT_TIMESTAMP()'; } };
+var sql = SqlString.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+To generate objects with a `toSqlString` method, the `SqlString.raw()` method can
+be used. This creates an object that will be left un-touched when using in a `?`
+placeholder, useful for using functions as dynamic values:
+
+**Caution** The string provided to `SqlString.raw()` will skip all escaping
+functions when used, so be careful when passing in unvalidated input.
+
+```js
+var CURRENT_TIMESTAMP = SqlString.raw('CURRENT_TIMESTAMP()');
+var sql = SqlString.format('UPDATE posts SET modified = ? WHERE id = ?', [CURRENT_TIMESTAMP, 42]);
+console.log(sql); // UPDATE posts SET modified = CURRENT_TIMESTAMP() WHERE id = 42
+```
+
+If you feel the need to escape queries by yourself, you can also use the escaping
+function directly:
+
+```js
+var sql = 'SELECT * FROM posts WHERE title=' + SqlString.escape('Hello MySQL');
+console.log(sql); // SELECT * FROM posts WHERE title='Hello MySQL'
+```
+
+### Escaping query identifiers
+
+If you can't trust an SQL identifier (database / table / column name) because it is
+provided by a user, you should escape it with `SqlString.escapeId(identifier)` like this:
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + SqlString.escapeId(sorter);
+console.log(sql); // SELECT * FROM posts ORDER BY `date`
+```
+
+It also supports adding qualified identifiers. It will escape both parts.
+
+```js
+var sorter = 'date';
+var sql    = 'SELECT * FROM posts ORDER BY ' + SqlString.escapeId('posts.' + sorter);
+console.log(sql); // SELECT * FROM posts ORDER BY `posts`.`date`
+```
+
+If you do not want to treat `.` as qualified identifiers, you can set the second
+argument to `true` in order to keep the string as a literal identifier:
+
+```js
+var sorter = 'date.2';
+var sql    = 'SELECT * FROM posts ORDER BY ' + SqlString.escapeId(sorter, true);
+console.log(sql); // SELECT * FROM posts ORDER BY `date.2`
+```
+
+Alternatively, you can use `??` characters as placeholders for identifiers you would
+like to have escaped like this:
+
+```js
+var userId = 1;
+var columns = ['username', 'email'];
+var sql     = SqlString.format('SELECT ?? FROM ?? WHERE id = ?', [columns, 'users', userId]);
+console.log(sql); // SELECT `username`, `email` FROM `users` WHERE id = 1
+```
+**Please note that this last character sequence is experimental and syntax might change**
+
+When you pass an Object to `.escape()` or `.format()`, `.escapeId()` is used to avoid SQL injection in object keys.
+
+### Formatting queries
+
+You can use `SqlString.format` to prepare a query with multiple insertion points,
+utilizing the proper escaping for ids and values. A simple example of this follows:
+
+```js
+var userId  = 1;
+var inserts = ['users', 'id', userId];
+var sql     = SqlString.format('SELECT * FROM ?? WHERE ?? = ?', inserts);
+console.log(sql); // SELECT * FROM `users` WHERE `id` = 1
+```
+
+Following this you then have a valid, escaped query that you can then send to the database safely.
+This is useful if you are looking to prepare the query before actually sending it to the database.
+You also have the option (but are not required) to pass in `stringifyObject` and `timeZone`,
+allowing you provide a custom means of turning objects into strings, as well as a
+location-specific/timezone-aware `Date`.
+
+This can be further combined with the `SqlString.raw()` helper to generate SQL
+that includes MySQL functions as dynamic vales:
+
+```js
+var userId = 1;
+var data   = { email: 'foobar@example.com', modified: SqlString.raw('NOW()') };
+var sql    = SqlString.format('UPDATE ?? SET ? WHERE `id` = ?', ['users', data, userId]);
+console.log(sql); // UPDATE `users` SET `email` = 'foobar@example.com', `modified` = NOW() WHERE `id` = 1
+```

+HTTP status utility for node.
+
+This module provides a list of status codes and messages sourced from
+a few different projects:
+
+  * The [IANA Status Code Registry](https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml)
+  * The [Node.js project](https://nodejs.org/)
+  * The [NGINX project](https://www.nginx.com/)
+  * The [Apache HTTP Server project](https://httpd.apache.org/)
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install statuses
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var status = require('statuses')
+```
+
+### status(code)
+
+Returns the status message string for a known HTTP status code. The code
+may be a number or a string. An error is thrown for an unknown status code.
+
+<!-- eslint-disable no-undef -->
+
+```js
+status(403) // => 'Forbidden'
+status('403') // => 'Forbidden'
+status(306) // throws
+```
+
+### status(msg)
+
+Returns the numeric status code for a known HTTP status message. The message
+is case-insensitive. An error is thrown for an unknown status message.
+
+<!-- eslint-disable no-undef -->
+
+```js
+status('forbidden') // => 403
+status('Forbidden') // => 403
+status('foo') // throws
+```
+
+### status.codes
+
+Returns an array of all the status codes as `Integer`s.
+
+### status.code[msg]
+
+Returns the numeric status code for a known status message (in lower-case),
+otherwise `undefined`.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status['not found'] // => 404
+```
+
+### status.empty[code]
+
+Returns `true` if a status code expects an empty body.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.empty[200] // => undefined
+status.empty[204] // => true
+status.empty[304] // => true
+```
+
+### status.message[code]
+
+Returns the string message for a known numeric status code, otherwise
+`undefined`. This object is the same format as the
+[Node.js http module `http.STATUS_CODES`](https://nodejs.org/dist/latest/docs/api/http.html#http_http_status_codes).
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.message[404] // => 'Not Found'
+```
+
+### status.redirect[code]
+
+Returns `true` if a status code is a valid redirect status.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.redirect[200] // => undefined
+status.redirect[301] // => true
+```
+
+### status.retry[code]
+
+Returns `true` if you should retry the rest.
+
+<!-- eslint-disable no-undef, no-unused-expressions -->
+
+```js
+status.retry[501] // => undefined
+status.retry[503] // => true
+```

+[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
+
+
+```bash

+```
+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+  project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+  notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).

+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+> Convert a string of words to a JavaScript identifier
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install toidentifier
+```
+
+## Example
+
+```js
+var toIdentifier = require('toidentifier')
+
+console.log(toIdentifier('Bad Request'))
+// => "BadRequest"
+```
+
+## API
+
+This CommonJS module exports a single default function: `toIdentifier`.
+
+### toIdentifier(string)
+
+Given a string as the argument, it will be transformed according to
+the following rules and the new string will be returned:
+
+1. Split into words separated by space characters (`0x20`).
+2. Upper case the first character of each word.
+3. Join the words together with no separator.
+4. Remove all non-word (`[0-9a-z_]`) characters.

+
+Infer the content-type of a request.
+
+### Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install type-is
+```
+
+## API
+
+```js
+var http = require('http')
+var typeis = require('type-is')
+
+http.createServer(function (req, res) {
+  var istext = typeis(req, ['text/*'])
+  res.end('you ' + (istext ? 'sent' : 'did not send') + ' me text')
+})
+```
+
+### typeis(request, types)
+
+Checks if the `request` is one of the `types`. If the request has no body,
+even if there is a `Content-Type` header, then `null` is returned. If the
+`Content-Type` header is invalid or does not matches any of the `types`, then
+`false` is returned. Otherwise, a string of the type that matched is returned.
+
+The `request` argument is expected to be a Node.js HTTP request. The `types`
+argument is an array of type strings.
+
+Each type in the `types` array can be one of the following:
+
+- A file extension name such as `json`. This name will be returned if matched.
+- A mime type such as `application/json`.
+- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`.
+  The full mime type will be returned if matched.
+- A suffix such as `+json`. This can be combined with a wildcard such as
+  `*/vnd+json` or `application/*+json`. The full mime type will be returned
+  if matched.
+
+Some examples to illustrate the inputs and returned value:
+
+<!-- eslint-disable no-undef -->
+
+```js
+// req.headers.content-type = 'application/json'
+
+typeis(req, ['json']) // => 'json'
+typeis(req, ['html', 'json']) // => 'json'
+typeis(req, ['application/*']) // => 'application/json'
+typeis(req, ['application/json']) // => 'application/json'
+
+typeis(req, ['html']) // => false
+```
+
+### typeis.hasBody(request)
+
+Returns a Boolean if the given `request` has a body, regardless of the
+`Content-Type` header.
+
+Having a body has no relation to how large the body is (it may be 0 bytes).
+This is similar to how file existence works. If a body does exist, then this
+indicates that there is data to read from the Node.js request stream.
+
+<!-- eslint-disable no-undef -->
+
+```js
+if (typeis.hasBody(req)) {
+  // read the body, since there is one
+
+  req.on('data', function (chunk) {
+    // ...
+  })
+}
+```
+
+### typeis.is(mediaType, types)
+
+Checks if the `mediaType` is one of the `types`. If the `mediaType` is invalid
+or does not matches any of the `types`, then `false` is returned. Otherwise, a
+string of the type that matched is returned.
+
+The `mediaType` argument is expected to be a
+[media type](https://tools.ietf.org/html/rfc6838) string. The `types` argument
+is an array of type strings.
+
+Each type in the `types` array can be one of the following:
+
+- A file extension name such as `json`. This name will be returned if matched.
+- A mime type such as `application/json`.
+- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`.
+  The full mime type will be returned if matched.
+- A suffix such as `+json`. This can be combined with a wildcard such as
+  `*/vnd+json` or `application/*+json`. The full mime type will be returned
+  if matched.
+
+Some examples to illustrate the inputs and returned value:
+
+<!-- eslint-disable no-undef -->
+
+```js
+var mediaType = 'application/json'
+
+typeis.is(mediaType, ['json']) // => 'json'
+typeis.is(mediaType, ['html', 'json']) // => 'json'
+typeis.is(mediaType, ['application/*']) // => 'application/json'
+typeis.is(mediaType, ['application/json']) // => 'application/json'
+
+typeis.is(mediaType, ['html']) // => false
+```
+
+## Examples
+
+### Example body parser
+
+```js
+var express = require('express')
+var typeis = require('type-is')
+
+var app = express()
+
+app.use(function bodyParser (req, res, next) {
+  if (!typeis.hasBody(req)) {
+    return next()
+  }
+
+  switch (typeis(req, ['urlencoded', 'json', 'multipart'])) {
+    case 'urlencoded':
+      // parse urlencoded body
+      throw new Error('implement urlencoded body parsing')
+    case 'json':
+      // parse json body
+      throw new Error('implement json body parsing')
+    case 'multipart':
+      // parse multipart body
+      throw new Error('implement multipart body parsing')
+    default:
+      // 415 error code
+      res.statusCode = 415
+      res.end()
+      break
+  }

+Unpipe a stream from all destinations.
+
+## Installation
+
+```sh
+$ npm install unpipe
+```
+
+## API
+
+```js
+var unpipe = require('unpipe')
+```
+
+### unpipe(stream)
+
+Unpipes all destinations from a given stream. With stream 2+, this is
+equivalent to `stream.unpipe()`. When used with streams 1 style streams
+(typically Node.js 0.8 and below), this module attempts to undo the
+actions done in `stream.pipe(dest)`.

+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();
+```

+
+Manipulate the HTTP Vary header
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): 
+
+```sh
+$ npm install vary
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var vary = require('vary')
+```
+
+### vary(res, field)
+
+Adds the given header `field` to the `Vary` response header of `res`.
+This can be a string of a single field, a string of a valid `Vary`
+header, or an array of multiple fields.
+
+This will append the header if not already listed, otherwise leaves
+it listed in the current location.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// Append "Origin" to the Vary header of the response
+vary(res, 'Origin')
+```
+
+### vary.append(header, field)
+
+Adds the given header `field` to the `Vary` response header string `header`.
+This can be a string of a single field, a string of a valid `Vary` header,
+or an array of multiple fields.
+
+This will append the header if not already listed, otherwise leaves
+it listed in the current location. The new header string is returned.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// Get header string appending "Origin" to "Accept, User-Agent"
+vary.append('Accept, User-Agent', 'Origin')
+```
+
+## Examples
+
+### Updating the Vary header when content is based on it
+
+```js
+var http = require('http')
+var vary = require('vary')
+
+http.createServer(function onRequest (req, res) {
+  // about to user-agent sniff
+  vary(res, 'User-Agent')
+
+  var ua = req.headers['user-agent'] || ''
+  var isMobile = /mobi|android|touch|mini/i.test(ua)
+
+  // serve site, depending on isMobile
+  res.setHeader('Content-Type', 'text/html')
+  res.end('You are (probably) ' + (isMobile ? '' : 'not ') + 'a mobile user')
+})
+```
+
