Using socket.io in Express 4 and express-generator's /bin/www

Question

So here is the deal: I'm trying to use socket.io in an express project. After Express Js 4 was lauched, i've updated my express-generator and now the app initial functions goes into `./bin/www` file, including those vars (www file contents: http://jsfiddle.net/avMa5/ ) ``` var server = app.listen(app.get('port'), function() {..} ``` (check it by `npm install -g express-generator` and then `express myApp` that being said, let's remember how socket.io docs ask us to fire it: ``` var app = require('express').createServer(); var io = require('socket.io')(app); ``` Ok but i can't do it inside app.js, like recommended. This should be done in ./bin/www in order to work. in ./bin/www this is what i can do to get it working: ``` var io = require('socket.io')(server) ``` Ok this works, but i can't use the io var anywhere else, and i really don't want to put my socket.io functions on `www` file. I guess this is just basic syntax, but I can't get this to work, not even using `module.exports = ser…

Accepted Answer

It turns out it really was some basic sintax problem.... I got these lines from this socket.io chat tutorial...

on ./bin/www, just after `var server = app.listen(.....)`

```
var io = require('socket.io').listen(server);
require('../sockets/base')(io);
```

so now I create the ../sockets/base.js file and put this little fellow inside it:

```
module.exports = function (io) { // io stuff here... io.on('conection..... }
```

Yeah! Now it works... So i guess i really had no option other than starting socket.io inside /bin/www , because that is where my http server was started. The goal is that now i can build socket functionality in other file(s), keeping the thing modular, by `require('fileHere')(io);`
