Custom OAuth2 Connection with Auth0

Understanding Auth0 authentication

Before we start with creating a custom OAuth2 connection in Auth0, it's worth to spend some time understanding the OAuth2 authentication process in Auth0. An OAuth2 authentication process starts with the application requesting Auth0 for authentication and ends with either the browser or the application server having an access token to represent the user. The access token can then be used to call the third party API on behalf of the user.

#Heroku, Ruby on Rails and PhantomJS

In this post, I’m going to show you how to modify an existing Ruby on Rails app running on Heroku’s Cedar stack to use PhantomJS for screen scraping. If you’ve never heard of PhantomJS, it’s a command-line WebKit-based browser (that supports JavaScript, cookies, etc.).

Let’s get started. This is a high-level overview of the required steps:

Modify your app to use multiple Heroku buildpacks.
Extend your app to use both the Ruby as well as the PhantomJS buildpacks.
Confirm that everything worked.

	import Vue from 'vue'
	import AppNavigation from '~/components/AppNavigation'

	// Mock our router, store and nuxt-link
	import Vuex from 'vuex'
	import storeCreate from '~/store'
	import VueRouter from 'vue-router'
	import NuxtLink from '~/.nuxt/components/nuxt-link'
	Vue.use(VueRouter)
	Vue.use(Vuex)

	const combos = [
	[1, 2, 3],
	[4, 5, 6],
	[7, 8, 9]
	]
	// Iterate over array elements
	for (const combo of combos)
	console.log(combo)

	// Iterate over string characters

	This example shows how you can use your data structure as a basis for
	your Firebase security rules to implement role-based security. We store
	each user by their Twitter uid, and use the following simplistic approach
	for user roles:

	0 - GUEST
	10 - USER
	20 - MODERATOR
