Introduction

We will build a todo list app in this tutorial, using Auth0 for sign in and sign up to our app. In this tutorial, you will learn how to use Passport to integrate with Auth0.

If you want to see where we are headed, here's an example of the final result: https://github.com/passport/todos-express-auth0

Before we dive in, you'll need a working development environment with Node.js and Git, as well as an editor and terminal of your choosing. Take a moment to set up these tools if you have not already done so.

You'll also need an Auth0 account. If you don't already have one, sign up now. This tutorial can be completed using Auth0's free plan.

Let's get started!

We are going to start with a starter app, which has all the scaffolding needed to build a todo list. Let's clone the app:

$ git clone https://github.com/passport/todos-express-starter.git auth0-tutorial

You now have a directory named 'auth0-tutorial'. Let's cd into it:

$ cd auth0-tutorial

Take a moment browse through the files in the starter app. As we work through this tutorial, we'll be using Express as our web framework, along with EJS as our template engine and CSS for styling. We will use SQLite as our database for storing data. Don't worry if you are not familiar with these technologies -- the necessary code will be provided at each step.

Now, let's install the dependencies:

$ npm install

And start the server:

$ npm start

Let's check to see if its working. Open http://localhost:3000 in your browser. You should be greeted with a page explaining how todos help you get things done.

We are going to make the sign in button work. But first, we need to create an app in Auth0.
