Fastapi

A solid foundation for standing up FastAPI projects without the usual migration headaches. Covers the current stack (Pydantic v2, SQLAlchemy 2.0 async, JWT auth) and actively prevents seven documented footguns including form validation bugs and async event loop blocking. The domain-based structure and dependency injection patterns keep things maintainable as the API grows. Particularly helpful if you're migrating from older FastAPI code, since it explicitly handles Pydantic v2 breaking changes and the Python 3.8 deprecation. Includes CORS setup, error handling, and testing with AsyncClient. Reach for this when you need production-grade patterns upfront rather than refactoring later.
