Using Passport for authentication in Node.js

Implementing authentication in Node.js applications can be simplified using the Passport library and MongoDB, as demonstrated in this guide. Passport, a modular authentication middleware, supports over 500 authentication mechanisms, including OAuth and JWT, making it easy to integrate multiple authentication types within a Node and Express-based application. The guide details the creation of a folder structure, setting up a MongoDB database, and using the mongoose-local strategy for authentication. It walks through setting up an Express server, implementing views and layouts with EJS, and configuring user schema with MongoDB. The guide emphasizes configuring Passport for local authentication, including session management with express-session, and demonstrates the complete process with a sample user registration. The tutorial provides a comprehensive walkthrough, with the final code available on GitHub, and suggests checking out Passport Docs for additional strategies.
