FastAPIView Repo is a modern, high-performance web framework for building APIs with Python. It's designed to be easy to use, fast to code, and ready for production. Key features include automatic data validation (using Pydantic), dependency injection, and automatic interactive API documentation (OpenAPI and Swagger UI).
