Building a Real-Time Chat App (Part 2) | Express Server & Authentication APIs with JWT

In this second part of the Real-Time Chat App series, we’re diving into the backend setup to get our chat app ready for real-time interactions and secure user authentication! Here’s what’s covered in this video:

Project Source Code: https://github.com/Raushan0300/Chat-App

What We’ll Accomplish:

• Express Server Setup: Configuring a robust Express server as our backend.
• Login & Signup APIs: Building and securing authentication routes with JWT (JSON Web Tokens) and bcryptjs for password hashing.
• Frontend Integration: Connecting our backend APIs to the frontend to allow new user registrations and secure logins.


By the end of this video, we’ll have user authentication set up and integrated with our chat app’s UI, so users can create accounts and securely log in to their chat profiles. Stay tuned for the next steps where we’ll enable real-time messaging!
