Building Production-Ready APIs with Modern Python Web Framework Introduction to FastAPI FastAPI is a modern, high-performance Python web framework for building APIs with Python 3.6+ using type hints. It’s built on top of ASGI (Asynchronous Server Gateway Interface) and combines the best aspects of modern Python development: automatic documentation, input validation, async support, and exceptional performance. Unlike traditional frameworks like Django and Flask that use WSGI (synchronous), FastAPI leverages ASGI for true asynchronous request handling, enabling dramatic performance improvements for I/O-bound operations. FastAPI automatically generates interactive API documentation (Swagger UI and ReDoc), validates request data, and provides intuitive dependency injection.…
