Description

FastAPI is a modern, high-performance, batteries-included Python web framework that's perfect for building RESTful APIs. It can handle both synchronous and asynchronous requests and has built-in support for data validation, JSON serialization, authentication and authorization, and OpenAPI.

Highlights:

1. Heavily inspired by Flask, it has a lightweight microframework feel with support for Flask-like route decorators.
2. It takes advantage of Python type hints for parameter declaration which enables data validation (via Pydantic) and OpenAPI/Swagger documentation.
3. Built on top of Starlette, it supports the development of asynchronous APIs.
4. It's fast. Since async is much more efficient than the traditional synchronous threading model, it can compete with Node and Go with regards to performance.

The tutorials and articles on TestDriven focus on developing and testing production-ready RESTful APIs along with serving up machine learning models.
