WebSockets

WebSockets provide a persistent connection between a client and server that both parties can use to start sending data at any time.

When to Use

• Chat Apps: Real-time messaging.
• Gaming: Multiplayer state synchronization (low latency).
• Collaborative Editing: Google Docs style co-authoring.
• Financial Dashboards: High-frequency trading updates.

Quick Start

// Server (Node.js with 'ws')
import { WebSocketServer } from "ws";

const wss = new WebSocketServer({ port: 8080 });

wss.on("connection", function connection(ws) {
  ws.on("message", function message(data) {
    console.log("received: %s", data);
    // Echo back
    ws.send();
  });

  ws.();
});
