An Introduction to FastAPI
summary
FastAPI claims to let you build REST APIs with minimal code while actually generating interactive docs and validation. It uses Starlette for async serving, builds an OpenAPI schema from Python type hints, and validates bodies with Pydantic models. The demo writes a recipe API endpoint by endpoint, shows Swagger UI running, returns JSON and HTML, supports websockets, and wires third‑party pieces like fastapi‑code‑generator and pagination. Examples compile and the generated docs and validation behave as described.
