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:

<%=
name = "Aleksandar"
age = 41
city = "Mozgovo"
%>

<script>
var object = JSON.parse('{"name":"<%= name %>", "age":"<%= age %>", "city":"<%= city %>"}')
console.log(object)
</script>

#!/bin/bash

set -ex

echo "Creating cluster with base name $1 on $2"

if [ -z "$1" ]
  then
    echo "Please provide the name of the cluster."
    exit -1

kubectl logs pgadmin-76gjgvvjh-yghg

Working with git remotes on Heroku

Generally, you will add a git remote for your Heroku app during the Heroku app creation process, i.e. heroku create. However, if you are working on an existing app and want to add git remotes to enable manual deploys, the following commands may be useful.

Adding a new remote

Add a remote for your Staging app and deploy

Note that on Heroku, you must always use master as the destination branch on the remote. If you want to deploy a different branch, you can use the syntax local_branch:destination_branch seen below (in this example, we push the local staging branch to the master branch on heroku.

$ git remote add staging https://git.heroku.com/staging-app.git

    var dispatchChange = function () {

            lastDispatched = newHref;
