Web Chat is a production-ready real-time messaging application designed for fast and reliable one-to-one communication. The platform supports secure user signup and login, private chats, real-time message delivery using Socket.IO, online/offline presence indicators, typing status, and in-app notifications. Media uploads are handled via Cloudinary, while MongoDB is used for user and message data persistence. The backend is built with Node.js and Express, the frontend with React and TypeScript, and the application is deployed on Render with a DevOps-focused setup for environment configuration, scalability, and monitoring.
