How to use SocketRocket with

The new iOS websocket library, SocketRocket, looks really awesome, and the chat example project is really sweet. The example chat server is written in Python, of which I know none. I’m slightly familiar with on node.js and prefer to try javascript. I tried connecting the SocketRocket TestChat simulator app to the node.js(6.10) but the connection was refused. (Also, I’m not a node expert either, so this may be a silly question).
