Laravel Broadcasting & Echo

When to Apply

Activate this skill when:

• Installing or configuring Laravel broadcasting (Reverb, Pusher, Ably)
• Creating events that implement ShouldBroadcast
• Defining broadcast channels and authorization
• Setting up Laravel Echo on the client side
• Listening for broadcast events, notifications, or model events
• Implementing client-to-client events (whisper)
• Working with presence channels for user awareness

Documentation

Use search-docs for detailed broadcasting patterns and documentation.

Basic Usage

Installing Broadcasting

php artisan install:broadcasting

Use flags for specific drivers: --reverb, --pusher, --ably. This creates config/broadcasting.php and routes/channels.php.

Creating a Broadcast Event

php artisan make:event OrderShipped

namespace App\Events;

use App\Models\Order;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
use Illuminate\Queue\SerializesModels;

class OrderShipped implements ShouldBroadcast
{
    use InteractsWithSockets, SerializesModels;

    public function __construct(public Order $order) {}

    public function broadcastOn(): array
    {
        return [new PrivateChannel('orders.'.$this->order->id)];
    }
}

Dispatch the event:

use App\Events\OrderShipped;

OrderShipped::dispatch($order);

Authorizing Channels

Define authorization in routes/channels.php:

use App\Models\Order;
use App\Models\User;

Broadcast::channel('orders.{orderId}', function (User $user, int $orderId) {
    return $user->id === Order::findOrNew($orderId)->user_id;
});

Create a channel class for complex authorization:

php artisan make:channel OrderChannel

List all registered channels:

php artisan channel:list
