In this lesson, we will take on two tasks:

  1. Implementing Laravel Eloquent API Resource
  2. Implementing CRUD operations for the Category model

At the end of this lesson, we will have a fully working CRUD for the Category model with transformed API responses:

Creating First Resource

Let's start by creating our first resource using the artisan command:

php artisan make:resource CategoryResource

This will create a scaffold for our resource:

app/Http/Resources/CategoryResource.php

use Illuminate\Http\Request;
use Illuminate\Http\Resources\Json\JsonResource;
 
class CategoryResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @return array<string, mixed>
     */
    public function toArray(Request $request): array
    {
        return parent::toArray($request);
    }
}

Here, we should focus on the toArray method. This is where we can transform our model data into the desired format. So let's add our transformation logic:

app/Http/Resources/CategoryResource.php

use App\Models\Category;
use Illuminate\Http\Request;
use Illuminate\Http\Resources\Json\JsonResource;
 
 
class CategoryResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @return array<string, mixed>
     */
    public function toArray(Request $request): array
    {
        return parent::toArray($request);
        return [
            'id' => $this->id,
            'name' => $this->name,
        ];
    }
}

We have also added a mixing annotation to the class. This will help IDE to understand that this resource is related to the Category model and provide...
