# Broadcasting

Real-time notifications with Laravel Echo.

## Setup Broadcasting

```php
<?php

// In NotificationServiceProvider
use Illuminate\Support\Facades\Broadcast;

Broadcast::channel('App.Models.User.{id}', function ($user, $id) {
    return (int) $user->id === (int) $id;
});
```

## Broadcast Notification

```php
<?php

use Laravilt\Notifications\Notification;

Notification::make()
    ->title('New message')

```
