Flask JWT Auth

This is originally taken from the wonderful article from RealPython I don't take any credit for it, just adapted some of the code to more of my likings.

Mostly I switched to Flask CLI instead of Flask-Script.

The project itself showcases how to implement a basic auth system using JWT tokens.

It basically provides a simple server that can:

• Register users
• Login users
• Generate JWT token for registered users
• Get user info assuming a valid JWT token is provided

It's a good way to understand how JWT works, although this example is not taking implementing a real Oauth dance using JWT tokens, which would be nice but would require more actors in place:

• Resource Server
• Authorization Server
• Client

Maybe a good idea for another test

Quick Start

Basics

1. Create and activate a virtual environment
2. Install the requirements

pip install -r requirements.txt

Set Environment Variables

Update project/server/config.py, and then run:

$ export APP_SETTINGS="project.server.config.DevelopmentConfig"

or

$ export APP_SETTINGS="project.server.config.ProductionConfig"

Alternatively, you can use the .flaskenv file to set environment variables too

Create DB

Create the databases in psql:

$ psql
# create database flask_jwt_auth
# create database flask_jwt_auth_testing
# \q

Create the tables and run the migrations:

$ flask create_db
$ flask db init
$ flask db migrate

Run the Application

$ flask run

So access the application at the address http://localhost:5000/

Testing

Without coverage:

$ flask test

With coverage:

$ flask cov
