Share ko lang po sa mga nag aaral ng JavaScript. Pwede din kayo mag Socket programming (NodeJS), eto multi client chat server.

chatserver.js

var net = require('net');

var clients = [];
net.createServer(function (socket) {
  clients.push(socket);
  socket.write('Who are you? ');
  socket.on('data', function (message) {
    if (!socket.chatname)
      return socket.chatname = message.toString().trim();
    clients.forEach(function (client) {
      client.write(socket.chatname + '> ' + message.toString());
    });
  });
}).listen(10000);
