ChatWave — Real-Time Messaging & Calling Platform

ChatWave is an enterprise-grade real-time collaboration application supporting direct and group communications, voice notes, media sharing, emoji reactions, and full-screen WebRTC peer-to-peer audio/video calls with screen sharing. Built with NestJS on the backend and Next.js with Redux Toolkit on the frontend, the platform harmonizes RTK Query REST caching with Socket.IO bidirectional events to ensure instant message delivery, live presence indicators, and seamless incoming call overlay alerts.
