FastAPI Insights

What is FastAPI?

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.7+ based on standard Python type hints. It's easy to use and learn, and it is designed to be developer-friendly, allowing for faster development times. It's commonly used for creating RESTful APIs, web applications, and microservices. It leverages Starlette for the web parts and Pydantic for data validation and settings management.
