Authentication With PassportJS

Introduction

In previous lessons, we learned how important it is to have your user managed (saved and retrieved) successfully. In this lab, you will do it one more time, just to make sure we are ready to move forward into new knowledge conquers 😉 Overall, the goal is to understand how authentication and authorization work in a web applications, why these features are useful and to be able to implement signup and login features using Passport.

Requirements

• Fork this repo
• Clone this repo

Submission

• Upon completion, run the following commands:

git add .
git commit -m "done"
git push origin master

• Create Pull Request so your TAs can check up your work.

Introductions

The starter-code provides the basic layout and organization for this assignment.

Iteration 0 | Initialize the project

After forking and cloning the project, you will have to add a starter_code/.env file:

PORT=3000

And you have to install all the dependencies:

$ cd starter_code
$ npm install

Now you are ready to start 🚀

Iteration #1: The Signup 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, 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.hbs file.

Now, in that .hbs 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 passportRouter.js to receive the data from the signup form and create a new user with the data.

Make sure you install bcrypt (or bcryptjs) and passport npm packages and require it in passportRouter.js.

Iteration #2: The Login Feature

In order to add the login feature, let's add one GET route to our router to display the login page. views/passport/login.hbs is empty so let's fill it with some login form. Once we have the form, let's add another route to the router to receive that data and log the user in. The form should make a POST request to /login.

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.hbs. This page is referenced in the passportRouter.js 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, login, and then visit the page, where they will receive a personalized greeting.

Happy coding! ❤️
