Need help on createWebSocketServer, missing front-end code

[MarByteBeep]

When trying to follow the docs here:

https://github.com/solidjs-community/solid-primitives/tree/main/packages/websocket

it's not clear to me how I should use pingPong, (see Setting up a websocket server) in a front-end situation. That constant has a single method called connect(), but when trying to call that function from front-end, I get Cannot connect to websocket server on the server itself.

So to me it's not entirely clear on how to use createWebSocketServer. It would be great if the documentation contains a simple working example with both front-end and back-end functionality.
