Introduction

You may already know how Passport works and how to integrate it in your projects. Now it's time to practice by creating an Express application with Passport.

Iteration #1: The Sign-up Feature

The repo you cloned comes with a User model and a router file already made for you. It also has all the views you need there, although some are empty.

Add a new route to your passportRouter.js file with the path /signup and point it to your views/passport/signup.ejs file.

Now, in that file, add a form that makes a POST request to /signup, with a field for username and password.

Finally, add a post route to your passportRoute to receive the data from the signup form and create a new user with the data.

Iteration #2: The Login Feature

In order to add the login feature, let's add 1 get route to our router to display the login page. Once we have that, let's add a form to our views/passport/login.ejs file. The form should make a POST request to /login. Once we have the form, let's add another route to the router to receive that data and log the user in.

But Wait

In order to do that, we need to configure Sessions and initialize a session with passport in our app.js file. We also need to add the passport.serializeUser functions as well as defining the Passport Local Strategy.

Private Page

In the repo you forked, there is a file called private.ejs. This page is referenced in the Passport Router with the path /private-page. We use the ensureLogin.ensureLoggedIn() function to make sure that the user is logged in before viewing this page.

If everything worked correctly, the user should be able to sign up, log in, and then visit the page, where they will receive a personalized greeting.

/Happy coding!
