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.

Notes

This guide uses Kamal 1.8.1

Motivation

Example of Kamal deployment from Github Actions.

Add your applications .env variables to the Github repo as a repository secret, you can find this under the repo settings => secrets and variables => actions

https://github.com/username/repo_name/settings/secrets/actions

you are going to need an ssh private key that your deployment server is aware of (add public key to servers .ssh/authorized_keys) and add the ssh private key as a repo secret

create action workflows
