## Folder Structure

### Root-Level Files:
- **`.env`**: Stores environment variables (e.g., secrets, database URL). Keep this out of version control.
- **`README.md`**: Comprehensive guide to the project.
- **`requirements.txt`**: Contains all dependencies for the project.
- **`alembic/`**: Database migrations directory.

### Application Directory (`app/`):
- **`main.py`**: Entry point of the FastAPI application.
- **`config/`**: Contains configuration files.
  - **`settings.py`**: Centralized configuration, like database connection URL or JWT secret.
- **`routers/`**: Contains API endpoint routers organized by features.
  - Examples: `auth.py`, `users.py`, `products.py`, `orders.py`, `admin.py`.
- **`models/`**: SQLAlchemy models defining database tables.
  - Examples: `user.py`, `product.py`, `order.py`.
- **`schemas/`**: Pydantic schemas for request/response validation and serialization.
  - Examples: `user.py`, `product.py`, `order.py`.
- **`services/`**: Business logic functions separated from routers for reusability and clarity.
  - Examples: `auth_service.py`, `user_service.py`, `order_service.py`.
- **`utils/`**: Utility functions like hashing, token generation, and pagination.
  - Examples: `hashing.py`, `token.py`, `pagination.py`.
- **`database/`**: Manages database session and connection.
  - **`session.py`**: SQLAlchemy session setup.
- **`middlewares/`**: Custom middleware like rate limiting.
  - Example: `rate_limiter.py`.
