Doesn't work in cloud9 IDE

[baio]

I've installed socket module - npm install socket.io

When I create server simple like this:

var io = require('socket.io').listen(process.env.C9_PORT);

When I got this exception:

debugger listening on port 5860

throw e; // process.nextTick error, or 'error' event on first tick

Remember the 0.7 API changed. Please consult the README.

Hmmm.Is it meant what c9.io now has obsoleted version of the module and if so when it will be updated?

[MikeTatsky]

Sorry, I also can not run socket.io on c9.io
Here is log

Any suggestions?

Tip: you can access long running processes, like a server, at 'http://zingsocketio.mikhailtatsky_1.c9.io'.
Important: in your scripts, use 'process.env.PORT' as port and 'process.env.IP' as host.

What are you passing into the listen call?

[MikeTatsky]

I tried this

var io = require('socket.io').listen(process.env.PORT, process.env.IP);

and just this

var io = require('socket.io').listen(process.env.PORT);

[GICodeWarrior]

It looks like process.env.PORT is a Number object instead of a primitive. Socket.io probably shouldn't care, but give this a try.

var io = require('socket.io').listen(process.env.PORT.valueOf());

[MikeTatsky]

Thank you for idea

process.env.PORT is string.
I tryed your varient. It does not work because return string.

var io = require('socket.io').listen(process.env.PORT.valueOf());

But these works.

var io = require('socket.io').listen(Number(process.env.PORT));

and

var io = require('socket.io').listen(+process.env.PORT);

+1 this was the same problem I encountered on Heroku. Also worth noting on heroku was that for SSL + WebSockets to work, I had to enable WebSocket support first, and then provision the SSL endpoint: https://devcenter.heroku.com/articles/heroku-labs-websockets
