Fastapi Development

This covers the FastAPI fundamentals you need to ship production async Python APIs. You get guides for Pydantic validation, SQLAlchemy async queries, JWT auth, dependency injection, and the full application setup with CORS and middleware. The reference docs show actual implementations for service layers and route handlers, not just conceptual stuff. The best practices section is solid on what to avoid, like returning raw database models or trusting unvalidated input. If you're building a modern Python backend and want type safety with automatic OpenAPI docs, this gets you past the boilerplate quickly. Assumes you already know why you want FastAPI over Flask or Django.
