useSWRSubscription With WebSocket: Possibility To Send Data

[piet-maier]

First off: Please correct me if I am completely wrong and it is already possible to use the useSWRSubscription hook with a web socket and send data back to the server. As far as I can tell this is not the case.

I know that the point of the swr package is to fetch data, and not to send it. However, when offering a hook that can be used to handle a web socket connection, I find it somewhat weird that the user does not have the possibility to also send data back to the server, which arguably is half of what web sockets are about.

My proposal would therefore be: In the same or a similar way that the hook accepts a function to establish the connection and attach event listeners for incoming messages, it should provide a possibility to send messages. The simplest way would be exposing the socket itself, so that the user can call send on it.

One could, of course, store the socket in an external variable when first creating it, but I do not think that is an ideal solution, if only because that means creating multiple references to it.

Any leads on this?
