cli.onConnect(() => { //call every time when connection successfully established
    console.log("connected");
    socket.emit("some_event", {"some_payload": "yep"}); //c
});
cli.onError(err => {  //call every time when error occurred while connecting or data deserializing

});
cli.onDisconnect(evt => { //call every time when connection could not established or closed
    if (!evt.wasClean) { //indicate that connection was closed by client or server
        console.error(evt);
    }
    setTimeout(() => socket.connect(), 1000); //for automatically reconnection just call connect() once again
