Modern FastAPI uses an asynccontextmanager lifespan handler to manage startup initialization and shutdown cleanup cleanly.
FastAPI handles synchronous def functions by running them in an internal threadpool, preventing blocking of the async event loop.
FastAPI is built directly on top of Starlette for web routing and Pydantic for data schemas.
… incrementally replaces monolithic functionality with microservices behind an API gateway, minimizing migration risk.
FastAPI achieves high performance by leveraging ASGI (Starlette) and native async execution for non-blocking I/O.
FastAPI utilizes Pydantic models to enforce request data schema validation and automatically serialize response data.
FastAPI inspects route code type annotations to automatically output an OpenAPI schema rendered via interactive Swagger UI.
As an ASGI framework, FastAPI requires an ASGI server like Uvicorn or Hypercorn to process asynchronous request loops.
