Auth0 + Node.js on Heroku

A starter template for server-side authentication with Node.js using Auth0 (deployable to Heroku).

Based off of the official Auth0 Node.js Web App Sample.

Set up Auth0

Setup for Auth0 is fast and easy:

  1. Sign up for a free account at Auth0, go to the Dashboard and hit the Create button: Auth0 Dashboard
  2. Create an application with the "Regular Web Application" template: Create Regular Web Application
  3. Go to the Settings tab and make a note of the Domain, Client ID and Client Secret. This information will be used for the Heroku setup. Settings tab for application

Set up Heroku

Create a Heroku account at Heroku - Sign up, and then click on this button:


This will set up a new application on your Heroku account using this repo as a template.

Choose your own app name, and use it in the AUTH0_CALLBACK_URL field.

During setup you'll also be asked for some other environment variables, which is the information that we noted earlier in the Auth0 setup:

Fill in Heroku environment variables

After Heroku is set up, return to the Auth0 Settings page and enter the URL in the Allowed urls (replace YOUR-APP with the App name that you chose):

  1. Enter your Allowed Callback URLs:
  2. Enter your Allowed Logout URLs:

It should appear like this:

Auth0 Callback URLs Configuration Auth0 Save Changes

Now everything should be set up! If you go to the application, it should allow you to register and log in to view your account details:

Run the Server Locally

If you want to run the server locally, you can do this as follows:

Install the dependencies.

npm install

Copy the contents of .env.example to a new file called .env and replace the values for AUTH0_DOMAIN, AUTH0_CLIENT_ID, and AUTH0_CLIENT_SECRET with your Auth0 information (from the Settings page). Replace EXPRESS_SESSION_SECRET with a secret to be used for the session.

# Copy configuration to replace with your own information
cp .env.example .env

Run the app.

npm start

The app will be served at localhost:3000.
