Building RESTful APIs with Python FastAPI

FastAPI is changing the way we build backends in Python. It’s fast, typed, and provides out-of-the-box documentation with Swagger UI.

Why FastAPI?

• Speed: Built on top of Starlette and Pydantic, it’s as fast as Node.js and Go.
• Asynchronous Support: Built-in async and await support.
• Type Safety: Leveraging Python 3.6+ type hints to automatically validate requests.

My First Project

I used FastAPI for the CoolHarlems Inventory System to handle high-concurrency stock updates, and it performed beautifully under pressure.
