The Challenge
Building a real-time messaging web application that handles concurrent chat connections, state synchronization, and instant typing indicators without causing rendering bottlenecks in the browser.
Research & Strategy
We analyzed common user patterns on WhatsApp Web to design a layout optimized for multi-pane chat lists, quick message search, and media management. Ensuring light/dark mode consistency and robust socket reconnection strategies were key user needs.
The Solution
Developed a high-performance messaging interface utilizing WebSocket connections for instant message transmission, Zustand for global state management, and optimized asset loading for file/image attachments. Reconnections are handled gracefully with offline message caching.
