Real-time Chat & Messaging App
ChatApp is a production-ready cross-platform real-time messaging application built with React Native, Expo, Node.js, and Socket.IO. Create conversations with other users, send instant messages with real-time delivery, see when users are typing, track user presence (online/offline status), and add emoji reactions to messages. The app features comprehensive user discovery and search, conversation management with deletion, paginated message history, read receipts for delivered messages, and responsive design optimized for iOS and Android. The backend provides robust JWT-based authentication, WebSocket support via Socket.IO, REST API endpoints, and is ready for Firebase integration. Perfect for demonstrating real-time architecture, distributed systems knowledge, and modern mobile development patterns.
