Difference between "listen on" and "connect to" in Node-RED sockets

Question

I'm learning Node-RED and trying to use its WebSockets node. I can't find any documentation that explains the difference between "listen on" and "connect to" type of sockets. Can someone explain that to me or point me in the right direction?

Answer 1

The WebSocket nodes can be configured to either act as a WebSocket Client or Server.

• connect to a remote WebSocket server - in other words, act as a Client
• listen on a path (eg /my-websocket-endpoint) hosted by the runtime server for connections coming into it - in other words, act as a Server

So the choice will depend on whether you need to connect to a remote server, or listen of connections coming into your server.
