MingleMate

Overview

MingleMate is a real-time chat application designed to handle high concurrency with a smooth user experience. Built with React.js, Tailwind CSS, DaisyUI, and Socket.IO, users can create accounts, join conversations, and exchange messages instantly. You can view the source code on GitHub here: Chat-App. The project focuses on the fundamentals of real-time web apps: persistent connections, secure authentication, efficient database reads/writes, and a responsive interface that stays usable under load.

Tech Stack

The frontend is built with React.js, while the backend runs on Node.js with Socket.io for bidirectional WebSocket communication. MongoDB stores user accounts, chat rooms, and message history with indexes tuned for common query patterns. JWT authentication secures API routes and socket connections, ensuring only authenticated users can send and receive messages.

Highlights

Stress-tested with 100+ concurrent users maintaining stable real-time message delivery.
Implemented JWT-based auth with protected routes and socket handshake validation.
Optimized MongoDB queries and indexes to keep latency low during peak usage.
Deployed a live demo on Render with a responsive UI across screen sizes.
