An Interface for opening a connection on a given address, notifying you when it's connected or disconnected

Once this detects it's available, make sure to set your state's SocketId so you can actually send and receive messages. And once it's disconnected, set your state's SocketId back to nothing:

case state.socketId of
    Nothing ->
        Web.Socket.connectTo "ws://127.0.0.1:9000"
            |> Web.interfaceMap
                (\connectionChanged ->
                    case connectionChanged of
                        Web.SocketConnected socketId ->
                            { state | socketId = socketId |> Just }


                        Web.SocketDisconnected ->
                            { state | socketId = Nothing }
                )


    Just socketId ->
        Web.Socket.message socketId "Meow"
