iframe: Module name 'ws' has not been loaded yet for context

Module name 'ws' has not been loaded yet for context _. use require( )

I want to use Websocket. For this, I used this web site websocket.

I installed Node.js by


curl -sL http://ift.tt/1oa11OK | sudo bash -
sudo apt-get install -y nodejs

and I installed ws by


  npm install ws

in my file server.html I have:


<html>
<head>
<script data-main="main" src="require.js"></script>
</head>
<body>
</body>
</html>

and in my main.js I have:


var WebSocketServer = require('ws').Server
      , wss = new WebSocketServer({ port: 8080 });

    wss.on('connection', function connection(ws) {
      ws.on('message', function incoming(message) {
        console.log('received: %s', message);
      });

      ws.send('something');
    });

the folder node_modules for ws is in the same directory as the file require.js.

The problem when I type in the browser http://my_ip/server.html, The websocket is not created and the console dispaly this error: Module name 'ws' has not been loaded yet for context _. use require( ).

Anyone know how to fixe this? I guess that JS is asynchronous, which means it continue executing the code without waiting loading file to be finished.

Thanks for reply
