Instant Talk – A Real Time Seamless Communication Using Mern Stack

This project, titled "Instant Talk – A Real Time Seamless Communication Using MERN Stack," focuses on building a modern messaging web application inspired by WhatsApp Web. Using the MERN stack (MongoDB, Express.js, React.js, Node.js), the system ensures real-time communication using Web Sockets via Socket.IO. It supports features such as user authentication (using JWT), one-to-one and group messaging, media sharing, real-time notifications, and audio/video calling powered by WebRTC. Chat histories are persistently stored in MongoDB Atlas. With the front end built in React and backend APIs in Express.js, the application showcases robust integration, performance, and security. This project not only replicates existing chat platforms but also explores enhancements like message scheduling and encryption. It reinforces full-stack development skills and addresses real-world challenges in scalable and secure web systems.
