Pure Flask example
=====================================
In this example, we are exposing 4 endpoints in the server.
An index endpoint, 2 authentication endpoints, and a user profile endpoint.
We are also using the ``jwt_required`` decorator provided by
the `Flask-JWT-Extended` extension to simulate the authentication process.
This is a very classic example of REST APIs implemented with Flask.
Checkout :doc:`flask-mux` to learn how to integrate ``Flask-Mux``
with this app to make it more modular.
