<?php

// php artisan make:observer PostObserver --model=Post
use Illuminate\Database\Eloquent\Attributes\ObservedBy;

#[ObservedBy([PostObserver::class])]
class Post extends Model {}

class PostObserver
{
    public function created(Post $post): void
    {
        // e.g. clear cache, send notification
    }
}

Moves model lifecycle logic (created, updated, deleted) out of controllers into one class. The #[ObservedBy] attribute registers it without a service provider.
