Minimal Javascript websocket client/server

websockets.js

// server
ws = require('ws');
wss = new ws.Server({ port: 8033 });
wss.on('connection', function(s) {
  console.log("got connection", s);
  s.on('message', function incoming(message) {
    console.log("received", message);
  });
});

// client
var ws = new WebSocket("ws://localhost:8033/");
ws.onopen = function() {
  console.log("open", arguments);
  ws.send("Hello Mr. Server!\r\n");
};
ws.onmessage = function() { console.log("message", arguments); };
ws.onclose = function() { console.log("close"); };
