JWT Auth + Refresh Tokens in Rails

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:

Dispatch jQuery events as regular DOM events
# ~ Dispatch jQuery events as regular DOM events ~
#
# Delegated events are given a new name in the format `jquery:<original event name>`.
# If you delegate `ajax:send` you will be able to listen for `jquery:ajax:send`
# on native event listeners such as Stimulus actions and `EventTarget.addEventListener`.
#
# Notes:
# * The first parameter must be called "event".
# * The parameters can be accessed as members on the `event.detail` object.
