JWT Auth + Refresh Tokens in Rails

This is just some code I recently used in my development application in order to add token-based authentication for my api-only rails app. The api-client was to be consumed by a mobile application, so I needed an authentication solution that would keep the user logged in indefinetly and the only way to do this was either using refresh tokens or sliding sessions.

I also needed a way to both blacklist and whitelist tokens based on a unique identifier (jti)

Before trying it out DIY, I considered using:

Rails API-Only Social Login

This is another piece of code I've extrapolated from a Ruby on Rails project I'm currently working on. The code implmenets social login with a RoR API-based application, targeted at API clients.

The setup does not involve any browser-redirects or sessions as you would have to use working with Omniauth. Instead, what it does is takes an access_token generated on client-side SDKs, retireves user info from the access token and creates a new user and Identity in the database.

This setup works with native applications as described in the Google iOS Sign In Docs (see Authenticating with a backend server)
