The Overview

This real-time chat application delivers a seamless messaging experience built on the MERN stack. Socket.io enables instant message delivery with typing indicators and online status tracking.

The Journey

"Ensuring reliable message delivery and synchronization across multiple concurrent sessions required careful Socket.io event handling. Managing WebSocket connections alongside JWT token refresh cycles without dropping messages was a nuanced challenge. Optimizing Zustand stores to prevent unnecessary re-renders in a high-frequency update environment was also important for maintaining performance."
