Flask and Swagger: The Ultimate Guide to Presenting API Documentation

I have created a compact service using flask and have also drafted a swagger yaml file to outline its API. What is the best way to make this swagger file accessible through the flask app?

To clarify, I am not looking to directly expose the file itself (send_from_directory), but rather to set up a new endpoint that will display it as a swagger-ui (ideally interactive).

Answer №1

Alright, here's how I tackled it.

I employed the use of flasgger to wrap my app with flasgger.Swagger. Following that, I implemented 2 endpoints:

  1. /_api which serves the YAML file (using send_from_directory)
  2. /api redirects to the flasgger API /apidocs/index.html?url=/api. While I believe there may be a more efficient way to accomplish this, unfortunately, I was unable to locate it.

Answer №3

Here are three different methods to accomplish this task:

  • Utilizing a Restful API (refer to Api.doc)
  • Obtaining swagger templates
  • Registering blueprints (from either flask-swagger-ui or similar tools)
