FastAPI Backend with Tortoise ORM and Async Functionality

Features

Backend Logic

• User Management:
  • No signup functionality; admins add users.
  • Users receive an invite to set up their password.
  • Users cannot delete themselves or change their email; these actions are restricted to admins.
• Authentication:
  • JWT-based authentication with access and refresh tokens.
  • Refresh tokens are stored as HttpOnly cookies for added security.

API and Database Handling

• Fully asynchronous API and database interactions:
  • Async API Handling: Built with FastAPI for high performance.
  • Async Database I/O: Powered by Tortoise ORM with asynchronous database operations.
• Testing:
  • API routes are tested using httpx.AsyncClient for comprehensive and efficient async testing.
• WebSocket Endpoint:
  • Designed to interact with OpenAI services, enabling real-time communication.

Traefik Configuration

Features

• DNS Challenge:
  • SSL certificates are automatically managed via DNS challenge using AWS Route 53 access keys.
• Redirection:
  • Regex-based logic to redirect traffic from the naked domain (example.com) to the www subdomain (www.example.com).

Tools and Technologies

• Backend: FastAPI, Tortoise ORM
• Testing: httpx.AsyncClient
• Authentication: JWT with HttpOnly cookies
• WebSockets: Real-time endpoint for OpenAI integration
• Traefik: Reverse proxy with automatic SSL management and domain redirection
• AWS Route 53: DNS hosting for domain management

Example Use Cases

• Admin invites users to set up their accounts securely.
• Users access APIs and WebSocket services with robust authentication mechanisms.
• Traefik handles domain-level redirections and SSL with minimal configuration effort.

This architecture ensures high performance, scalability, and security for modern web applications.
