FastAPI

FastAPI is a modern Python web framework used for APIs, content services and the back ends of many websites. Articles under this tag show how to add an RSS or Atom feed to a FastAPI project. They cover building the XML with libraries or templates, returning the right media type and generating absolute URLs behind proxies. Dates, caching with ETags and automated tests are explained as well. Each guide ends with how to connect the finished feed to automatic social posting.
