This covers FastAPI development from routes and Pydantic models through dependency injection, JWT authentication, and async database operations with SQLAlchemy. You get practical examples for the full stack: OAuth2 security, background tasks, request validation with custom validators, and testing with TestClient. The code samples are production oriented, showing real patterns like database session management and password hashing with bcrypt. Use this when you're building async Python APIs and want type safety with automatic OpenAPI docs. It assumes you know Python but treats FastAPI's dependency injection system and async patterns as first class concerns rather than afterthoughts.
