namespace common\models;

use mkiselev\broadcasting\channels\PrivateChannel;
use mkiselev\broadcasting\events\BroadcastEvent;

class SignalEvent extends BroadcastEvent
{
    public $someParam = 42;

    public function broadcastOn()
    {
        return new PrivateChannel('signal');
    }

    public function broadcastAs()

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001'
});

Echo.channel('signal')
    .listen('.new', function(e) {
        console.log(e.someParam);
    });
