Automatic Reconnection on the Client
Build a resilient browser WebSocket client that detects drops and reconnects automatically with exponential backoff and message queuing.
Connections Drop
Networks are unreliable. Wi-Fi hiccups, tabs sleep, and servers restart. A good client detects a closed socket and reconnects without the user noticing.
Detecting a Drop
The browser fires close when the connection ends and error on failures. Reconnection logic hooks into close.
ws.addEventListener('close', () => {
scheduleReconnect();
