I have a Php Framework. Recently I've put some burden on NODE.js shoulders. Now I don't know where to put node.js files. For now I have one file, but It'll get bloated in the near future. Where do you suggest to put these files?

Thanks in advance.

EDIT :
I'm asking to see if putting Nodejs files inside the php framework best practice. Or should we put all nodejs file in www folder without ever caring about our PHP framework.

You shouldn't put your node.js code in any web accessible folder (like www), as this is server code and it shouldn't be accessible from the web.
Your best bet is to just make another directory to host your node.js application which isn't in www or any other web accessible directory.
