I use a function node to connect to [socket.io](http://socket.io), thus creating a socket object in the Start tab.  
I need access to that socket object in the Stop section, to close the connection again.  
Alternatively, `node.on('close', ...)` would work, but node#on does not seem to be available in the Setup tab.

So here is the question:  
How do I access objects created in the start code from the stop code?

By setting a reference in node context.

on start

```auto
context.set('mySocket', mySocket)

```

on stop

```auto
const soc = context.get('mySocket')
soc.whatever()

```
