CHAT-MINGLE – A Full-Stack Real-Time Chatting Application

Abstract—This paper presents a project-specific real-time chat application that enables secure and instant messaging using modern web technologies. The goal is to design a decentralized yet efficient chat system where users can exchange text, media, and files securely over the internet. The system incorporates end-to-end encryption to ensure data privacy, while real-time messaging is achieved using WebSockets. We detail the system architecture, methodology, and implementation of the chat app and compare our approach with existing chat applications such as WhatsApp, Signal, and Telegram. We also reference the open-source repository that demonstrates the practical applicability of our project.
