A modern, production-ready FastAPI boilerplate with built-in authentication, user management, and notification features. This project follows best practices for API development and includes essential tools and configurations out of the box.

• FastAPI - Modern, fast (high-performance), web framework for building APIs
• SQLAlchemy 2.0 - Full async SQL toolkit and ORM
• Alembic - Database migrations
• JWT Authentication - Secure token-based authentication
• Pydantic v2 - Data validation and settings management
• Dependency Injection - Clean architecture with dependency injection
• WebSockets - Real-time bidirectional communication for notifications and live updates
• RabbitMQ Integration - Message queuing for background tasks and email notifications
• Async MySQL - Async database support with aiomysql
• Environment Configuration - Easy environment variable management
• CORS - Built-in CORS middleware
• Structured Logging - Ready for production logging with Loki support
• Type Hints - Full Python type support
• Email Service - Built-in email service for user notifications with queue support
• Gunicorn with uvloop - High-performance server with ultra-fast event loop implementation

• Python 3.13
• MySQL 8.0
• RabbitMQ 3.x - Message broker for background tasks
• uv - Fast Python package installer and resolver

1. Clone the repository:

   git clone [email protected]:{your_username}/python-fast-api.git
   cd python-fast-api

2. Create and activate a virtual environment using uv:

   uv venv
   source .venv/bin/activate  # On Windows: .venv\Scripts\activate

3. Install dependencies with uv:

   uv pip install -e .

4. Set up environment variables:

   cp .env.example .env
   # Edit .env with your configuration

5. Initialize the database:

   alembic upgrade head

Start the development server:

# Development mode with auto-reload
python server.py

# Production mode with Gunicorn and uvloop
gunicorn -c gunicorn.conf.py server:app

The API will be available at http://localhost:8000

API documentation:

• Swagger UI: http://localhost:8000/docs
• ReDoc: http://localhost:8000/redoc

The application uses RabbitMQ for background task processing. To process email notifications in the background:

# Start the email worker
python src/cmd/email_worker.py

This worker connects to RabbitMQ and processes email tasks from the queue, allowing the main application to continue processing requests without waiting for emails to be sent.
