React to Eloquent Model Events with Observers

// app/Observers/UserObserver.php
namespace App\Observers;

use App\Models\User;

class UserObserver
{
    public function created(User $user)
    {
        // Logic to run AFTER a User is created
        // e.g., send a welcome email, create a related profile record
        // Mail::to($user->email)->send(new WelcomeEmail($user));
    }

    public function updating(User $user)
    {
        // Logic to run BEFORE a User is updated
        // e.g., log changes, prevent certain updates based on conditions
    }

    public function deleted(User $user)
    {
        // Logic to run AFTER a User is deleted
        // e.g., clean up related records (if not using cascading deletes), notify admins
    }

    // Other events: creating, updated, saving, saved, restoring, restored, forceDeleted
}

// Register the observer in app/Providers/AppServiceProvider.php (or a dedicated ObserverServiceProvider)
namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Models\User;
use App\Observers\UserObserver;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        User::observe(UserObserver::class);
    }
