socketio connecting to another server?

[Torsten Schmale]

Hi,

I am looking for a node-red example or description showing how to establish a socketio connection from node-red to a server.

The only thing I find is the chat app https://flows.nodered.org/flow/71f7da3a14951acb67f94bac1f71812a

but this example makes use of node-red itself as socketio server

Thanx in advance

Not sure that you will find that. In most cases, we want Node-RED to be the server.

It might help if you explained what you are trying to do with the connection?

The server I want to connect provides a socket.io interface and provides update events. 

This interface is typically used by browser clients to refresh on event reception.

I want to connect to this interface now from node-red and trigger flows on certain topics.

Interesting that this hasn't been done yet by somebody. 

I guess I have to write my own socketio client then for node-red or can that be done with existing nodes?

There are several socketio client nodes on flows.nodered.org if you care to look

yes, but all outdated and not working as it seems.

the last thing I tried was node-red-contrib-socketio-client which led to corruption of my working node-red-contrib-socketio installation...

from my point of view,  node-red-contrib-socketio is the only package that works (at least for the chat example AND if this bug fix here is applied https://github.com/wperw/node-red-contrib-socketio/issues/7 )

Ahah right... OK at least that project seems to be alive and the author responded fairly recently... (ok back in Oct...) so you could maybe confirm the patch works - or help raise a PR on it ?
