Socket to me
summary
Demonstrates building real-time apps with the WebSockets API and Socket.IO on Node: live code shows io.sockets.on connection handlers, client io.connect, and JSON.stringify limits (DOM events crash). Compares alternatives (Comet, SSE, WebRTC), highlights subprotocols (WAMP, STOMP), and Socket.IO features like automatic reconnects, heartbeats, volatile messages and namespaces. Ships two demos — a multiuser canvas and a tiny market — both run but bots flood the server, prompting server-side throttling and validation as the necessary fix.
