Intro to FastAPI
summary
FastAPI is a Python web framework that uses standard Python type hints plus Pydantic to provide Pydantic validation and automatic OpenAPI docs without extra code: examples show path, query and JSON body handling, required vs default params, metadata, and nested list-of-object schemas with precise error messages. It builds on Starlette, reports ~15,000 GitHub stars and benchmarks over 9,000–15,000 req/s, includes dependency injection, websockets and background tasks, and works—avoid rewriting stable non-API apps unless migrating incrementally.
