Building APIs with FastAPI
FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.6+ based on standard Python type hints. Key features include: automatic interactive API documentation (Swagger UI and ReDoc), data validation using Pydantic, serialization, authentication, dependency injection, and background tasks. FastAPI is built on Starlette for web handling and Pydantic for data validation. It supports async/await for handling concurrent requests efficiently. FastAPI's use of type hints means you get excellent editor support with autocompletion and error checking. The framework is particularly well-suited for building RESTful APIs, microservices, and applications that need to handle high loads. Understanding FastAPI involves learning about path operations, request bodies, query parameters, response models, and dependency injection.
