How to handle additional websocket connection state

[lwojciechowski]

I made initial implementation of the websocket callbag. The problem I encountered is: how to tell the user that WebSocket is connected. So far I implemented buffer that stores the data that should be sent to the WebSocket connection, but I believe that information about successful connection is way too important to hide it inside callbag.

I checked WebsocketSubject from RxJs, and they allow to pass openedObervable in the config, that stores connection state.

Either use Object.defineProperty like :

return Object.defineProperty((type, data) => {
       // ...
    },
    'closed',
    {
        get: () => !ws || ws.readyState !== 1,
});

Or define a second source who tells if the connection is closed or not.
