socket.io doesn't seem to be starting and doesn't recognize io.configure method

Question

I am trying to get socket.io running with node/express (I have done this countless times - so I am pretty baffled). When I try to configure socket.io with the io.configure method I get an error:

io.configure(function() {
   ^
TypeError: Object #<Server> has no method 'configure'
    at Object.<anonymous> (/home/yz/webdev/ground/app.js:377:4)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:902:3

My code is exactly how it says to do it on socket.io - but I'll post it just in case:

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io').listen(server);

server.listen(8000);

//other declarations
app.use(...
passport.use(...

//some routes
app.get(...
app.post(...

io.configure(function() {
  io.set('transports', ['websocket','xhr-polling','flashsocket']);
  io.set('flash policy port', 10843);
});

io.sockets.on('connection', function (socket) {

  socket.on('message', function (data) {
    ...
  });
});

The error gets thrown at the io.configure method - I have done this before with other sites, I don't understand whey it isn't working now. Thanks.

UPDATE

I was just reading here that io.configure doesn't exist anymore - however, I can't seem to get it working the new way either. Here is my new code:

var express = require('express');
var app = express();
var server = require('http').createServer(app);
//var io = require('socket.io').listen(server);
var socket = require('socket.io')({
  'transports': ['websocket','xhr-polling','flashsocket'],
  'flash policy port': 10843
});

var io = socket.listen(server);

io.sockets.on('connection', function (socket) {

  socket.on('message', function (data) {
     ...
  });
});

I'm not getting any errors, socket.io just doesn't seem to be starting.

You're assigning io to a server, which is causing the problems when you attempt to call functions on io which are available from socket.io . Try replacing this line:

var io = require('socket.io').listen(server);

With this line:

var io = require('socket.io')(server);

The socket.io docs list a couple of configuration patterns you can take advantage of, and it is possible to create a server using socket.io . But since you're already creating a server, you shouldn't need to do it with socket.io .
