Creating seamless real-time experiences heavily relies on persistent dual-way communication. Polling is incredibly inefficient for mobile platforms, creating substantial battery drain.
By integrating Socket.io with a React Native frontend, combined with a Node.js signaling server, you can instantiate a low-latency persistent connection. The challenge always lies in background state management and network reconnects when shifting between LTE and WiFi.
Using AppState listeners to throttle or kill sockets in the background proved to be the golden ticket for mobile optimization.
