To install with YAML support: pip install -U 'apispec' To install apispec: pip install -U apispec I would recommend using Python 3, but Python 2 should work just fine. You will need to have Python installed on your machine. It supports Marshmallow and Flask, allowing you to re-use your code to generate a proper documentation! Some other libraries can do a lot of magic for you, but apispec is really simple to use and can sit next to your code without interfering with it. Thanks to the apispec lib, you can automagically generate a specification file (commonly named swagger.json) form your Flask code. We decided to follow the OpenAPI (aka Swagger 3.0) specification to build a solid documentation for our Flask-powered micro-services APIs. Any fresh CS student could write a small Python tool using it, just by following the documentation and its examples. Take the Twitter API: the docs are great, user-friendly and cover all the available endpoint with tips and examples. In the wild, they are many good examples of well-documented APIs. This article is the second part of Python Flask automatically generated Swagger 2.0 Document, in this article we are going to generate Swagger 3.0/Openapi Document.
