MERN Stack Real-Time Chat App is a full-stack chat application built using MongoDB, Express.js, React, and Node.js. The project demonstrates how to build a real-time messaging platform from scratch with user authentication, REST APIs, database integration, and live communication.
The application uses Socket.io to enable real-time messaging between users, while JWT authentication provides a secure login and authentication system. You will also work with User and Message schemas in MongoDB and create protected backend routes using secure middleware.
The source code provides the complete project implementation, making it useful for developers who want to learn MERN Stack development, real-time communication, authentication, API development, and database integration through a practical project.
