use Illuminate\Broadcasting\Channel; use Illuminate\Queue\SerializesModels; use Illuminate\Broadcasting\PrivateChannel; use Illuminate\Broadcasting\PresenceChannel; use Illuminate\Foundation\Events\Dispatchable; use Illuminate\Broadcasting\InteractsWithSockets; use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class TestEvent {
    use SerializesModels;
    public $message;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($message)
    {
        $this->message = $message;

    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return \Illuminate\Broadcasting\Channel|array
     */
    public function broadcastOn()
    {
        return new Channel ('Message');
    }

}

My head :

<script src="http://:6001/socket.io/socket.io.js"></script>

<meta name="csrf-token" content="">

My Controller:

public function dev(){
        event(new TestEvent("Hello"));
        return view('home');
    }

My Js file:

window.Echo.channel(`Message`)
    .listen('TestEvent', (data) => {
        console.log(data);
    });
