How do I create code to listen to websocket server. For example: ws://example.com/webEvent I dont know how to create web socket or even how to listen to it . Any help would be much appriciated

Have you checked the pallet of nodes? Node-RED already has a websocket node that will do this for you.

I know but i want to make a custom one with 1 extra functionallity.

[image] jake123: want to make a custom one with 1 extra functionallity If you have no idea how to create or listen you are in for a steep learning curve creating a node. Maybe if you explain this "1 extra functionallity" you could make a feature request for the existing websocket nodes? Maybe you could even provide a PR to the existing websocket nodes?

var stripped = msg.payload.trim(); var values = stripped.split('\n'); var datapointname = values[0].substring(37, values[0].length - 14); data = Number(values[1]); this is the extra functionallity

What's wrong with using the function node? I don't see the need to create yet another custom for such a specific use-case. Other than educational purposes, of course. :sweat_smile: Also, this functionality is too specific to be included into the standard websocket nodes.

I just need code that will create a socket that connects to ws://example.com

so drop a websocket node on the editor and set the address. No need to make a contrib node.

Yeah, educational purpose it is. Im trying to create a flow that will contain less nodes that it will normally contain.For training
