Module 4 - Advanced Features and Production Readiness

Explore advanced FastAPI capabilities including WebSockets, background tasks, and testing patterns that make your APIs production-ready.

📄️Background Tasks and Asynchronous Operations

Async endpoints, BackgroundTasks, asyncio.gather, and Celery in FastAPI — event loop blocking, error handling, and production limits.

📄️WebSockets and Real-Time Features

Build FastAPI WebSocket endpoints with connection management, broadcast messaging, JSON events, JWT auth, error handling, and scaling.

📄️Testing FastAPI Applications

Master FastAPI testing with pytest, TestClient, dependency overrides, and isolated test databases. Covers unit tests, integration tests, and error handling.

📄️Building Your First API — Task Manager (Part 4)

Implement background task notifications, WebSocket broadcasting, and complete pytest test coverage for FastAPI applications with correct mocking.
