Secure Real-Time Web-Based Chat Application Using MERN Stack and Google Authentication

–In the digital age, real-time communication has become a cornerstone for both personal and professional interaction. This research presents the design and development of a secure, web-based real-time chat application utilizing the MERN (MongoDB, Express.js, React, Node.js) stack. Unlike traditional methods requiring mobile numbers or QR codes, this application employs Google Authentication for user login, promoting ease of access and enhanced security. The system features real-time one-on-one messaging, online/offline user status, and supports multimedia message types including text, audio, and video. WebSockets are implemented for low-latency communication. The application ensures secure data handling and privacy through modern encryption techniques, aligning with the increasing demand for safe and effective communication tools. This research aims to contribute a scalable and user-friendly solution for seamless, real-time digital interaction.
