Reconnection Strategies
Reconnect reliably after drops.
Why Reconnect?
Networks are unreliable — Wi-Fi drops, laptops sleep, servers restart. A robust WebSocket client detects closure and automatically re-establishes the connection so the user experience stays seamless.
Naive Reconnect
The simplest approach reopens immediately on close. The danger: if the server is down, this hammers it in a tight loop.
function connect() {
const socket = new WebSocket(url);
socket.onclose = () => connect(); // too aggressive!
