[nodejs] [ReferenceError: html is not defined]

[Norman Khine]

i have this code:

var server = require('http').createServer(function(req, res){
  res.end(html);
});
server.listen(process.env.VCAP_APP_PORT || 9080);

var nowjs = require("now");
var everyone = nowjs.initialize(server);

everyone.now.distributeMessage = function(message){
  console.log('User '+this.now.name+' added message ' +message);
  everyone.now.receiveMessage(this.now.name, message);
};

and am using the now.js from https://github.com/jameskeane/now

when i run

% node app.js and then from my client i have this code:

....

  <script type="text/javascript" 
src="http://127.0.0.1:9080/nowjs/now.js";></script>
  <script type="text/javascript">
    $(document).ready(function(){
        now.receiveMessage = function(name, message){
        $("#messages").append('<br />' + '<a href="${path}">' + name + 
'</a>' + ': ' + message);
        }
        $("#send-button").click(function(){
        now.distributeMessage($("#text-input").val());
        $("#text-input").val("");
        });
      now.name = "${name}";
    });
  </script>
</body>

this works fine and the mesages are sent, but i get this console errors
