Build Fast & Well Documented APIs with FastAPI
Build beautifully documented APIs with Python’s relatively new backend framework called FastAPI. FastAPI lets you create very fast and well documented APIs with minimal code.
We go over most topics that you will need to know about when writing APIs using this framework. Namely, writing simple GET and POST endpoints, how to get automatic documentations & data validations, how to support query parameters, path parameters and request bodies, how to automatically validate your request inputs.
We will also look at slightly advanced use cases, such as, reading cookies and request headers, returning custom status codes and exceptions with helpful messages, kicking off asynchronous background tasks and supporting CORS for all or some of your origins.
