Tutorial : PassportJS Authentication in NodeJS

At some point we surely developed a simple authentication system with the use of conventional username and password in the application based on Node.js. Providing only one way authentication is not that appropriate for users. Instead of that, if we offer features such as “Login with Google”, “Login with Facebook”, users will definitely like the application. Creating new passwords and usernames will be more time consuming, frustrating and irritating and even users have to remember those passwords.

So, to make the authentication more user friendly, we must add the features such as social logins in application and allow users to login from any kind of social media platform such as Twitter, Facebook and Google too.

Today here, we are going to learn how to Implement PassportJS authentication in NodeJS. Here we are going to implement the features of Facebook login in the application based on Node.js.

Let’s see.

First let’s learn what is PassportJS?

according to the documentation.

“Passport is authentication middleware for Node.js. Extremely flexible and modular, a Passport can be unobtrusively dropped into any Express-based web application. A comprehensive set of strategies support authentication using a username and password, Facebook, Twitter, and more.“

Steps to Implement Facebook Login Feature in Node.js Application

  • Creating Facebook Developer Account
  • Project Structure and Setup
  • Initializing npm and Installing Dependencies
  • Basic Server Setup and Database Connection
  • Initial Model Setup
  • Set Up Routes
  • Define Passport Strategy: Logic for all the Routes
  • Run Server
