Using WS message in event loop

[makopov]

I have 3 questions here...

1. I'm trying to figure out how to pass the message received by the WS to the event loop, see code below.
2. Is this the right way to handle ws messages asynchronously? I notice delays with the more topics I subscribe to.
3. My IDE is showing that React Factory is deprecated, are there plans to stop usages of it in the future?

        $loop = Factory::create();
        $loop->addPeriodicTimer(1, function($message) {
           var_dump('loop: ' . date('Y-m-d H:i:s'));
           var_dump($message);
        });
        $api->setLoop($loop);

        $api->subscribePublicChannels($query, $channels, function (array $message, WebSocket $ws, LoopInterface $loop) use(&$exchange, &$interval, &$results) {
            // $loop->run();
            // print $message['data']['symbol'] . PHP_EOL;

            }
        }, function ($code, $reason) {
            echo "OnClose: {$code} {$reason}\n";
        });
