How To: Create a Flask API with JWT-Based Authentication (Overview)

This tutorial series provides step-by-step instructions and in-depth explanations to guide you through the process of creating a robust, production-quality REST API. The toolstack consists of Flask, Flask-RESTx, pyjwt, SQLAlchemy and other packages. Code quality is a major focus, with considerable time dedicated to testing (using pytest), logging and tools such as coverage, flake8 and mypy. The tutorial concludes by creating a process that continuously integrates (with tox, travis/circle CI, coveralls) and deploys the API (with either Github or Azure DevOps to Heroku).

How To: Create a Flask API with JWT-Based Authentication (Part 2)

Part 2 covers the basics of SQLAlchemy, the Flask-SQLAlchemy extension, and the Flask-Migrate extension. The process of creating a new database table to store user information by defining a class and “registering” it with SQLAlchemy is demonstrated. Next, setting up a system that manages changes to a database schema is thoroughly explained and demonstrated. After initializing the database, functions to encode and decode JSON Web Tokens (JWTs) are created. This section concludes with an introduction to pytest fixtures and examples of several test cases that verify the ability to encode/decode JWTs issued by our API.
