Halo Coding Challenge Python Microservice

React front-end can be found here. Its deployed through netlify here: https://laughing-hoover-481394.netlify.com/

This is a python microservice for halo's full-stack coding challenge. It uses JWT authenticationa and has a key-value store backed in a sqlite database. Its deployed on Digital Ocean and the base url for the api is https://17caf9f8.ngrok.io/. The service is backed by a SQLite database

JWT required endpoints need a bearer token in their header:

{
  headers: {
    'Authorization' : Bearer Token
  }
}

Authentication

This microservice uses JWT based authentication. For simplicity, the access token expires in 30 days but I've included endpoints for refresh tokens that could be used in a real application. The password is hashed using bcrypt. Users are stored in a users table with their username, hashed password and id. There is also a revoked token table that stores revoked tokens such as when a user logs out. JWTs are managed by Flask-JWT-Extended.

API

Failed authentication attemps result in 401. Internal errors are 500.
