Resource Controllers: Building Clean CRUD APIs

Resource controllers give you a standard way to implement CRUD logic for your models.

Instead of manually writing many routes and methods, Laravel generates them for you following best practices.

## Create a resource controller

```bash
php artisan make:controller PostController --resource
```

This generates methods:
- index, create, store  
- show, edit, update  
- destroy  

Each method maps to a CRUD operation.

## Register routes

```php
Route::resource('posts', PostController::class);
```

Laravel automatically creates all CRUD routes.

## How it connects

```

Resource controllers keep your code consistent and easy to maintain.

In the next tutorial, we will simplify controllers further using route model binding.
