title: nodejs net sockets + websocket without socket.io
body: <p>I'm trying to create something like chat using nodejs.
  I'm a newbie in nodejs and i want to create it without socket.io (i want to learn how it works).
  Here is the code i'm using.</p>
  
  <pre><code>var http = require('http');
  var net = require('net');
  
  
  var server = http.createServer(function(req,res){
  
      res.writeHead(200,{'content-type' : 'text/html'});
      res.write('&lt;a href="./lol/"&gt;lol&lt;/a&gt;&lt;br&gt;');
      res.end('hello world: '+req.url);
  
  
  
      var client = new net.Socket();
      client.connect('7001', '127.0.0.1', function() {
  
          console.log('CONNECTED TO: ');
          // Write a message to the socket as soon as the client is connected, the server will receive it as message from the client 
          client.write('I am Chuck Norris!');
  
      });
  
      // Add a 'data' event handler for the client socket
      // data is what the server sent to this socket
      client.on('data', function(data) {
  
          console.log('DATA: ' + data);
          // Close the client socket completely
          client.destroy();
  
      });
  
      // Add a 'close' event handler for the client socket
      client.on('close', function() {
          console.log('Connection closed');
      });
      //req.
  
  });
  server.listen(7000);
  
  
  require('net').createServer(function (socket) {
      console.log("connected");
  
      socket.on('data', function (data) {
          console.log(data.toString());
      });
  }).listen(7001);
  </code></pre>
  
  <p>And all works fine, (i think).
  When i open localhost:7000 i'm getting in node CMD messages about "CONNECTED TO:" and "connected" and "I am Chack Norris".
  After that i'm trying to write in the browser console:</p>
  
  <pre><code>var conn = new WebSocket('ws://localhost:7001/');
  </code></pre>
  
  <p>Also no errors, but when i try this line:</p>
  
  <pre><code>conn.send('lol');
  </code></pre>
  
  <p>I'm getting an error: "Uncaught DOMException: Failed to execute 'send' on 'WebSocket': Still in CONNECTING state.(…)"</p>
  
  <p>And after some time i get one more error: "WebSocket connection to 'ws://localhost:7001/' failed: WebSocket opening handshake timed out"</p>
  
  <p>maybe this code is wrong, but i have tried everything that i found through google. Can someone help me with this?</p>
