Payloads

This is an MVP/POC.

Summary

Classes with the #[Payload] attribute can be resolved from the container and are hydrated automatically with data from the request payload. This enables strong type hints and intellisense for request bodies while decoupling the payload from the Request.

Validation

The optional validation provided by Payloads is a thin, strongly typed, wrapper around Laravel's built-in validation.

Hydration

• Class Instances
• Arrays & Collections
• Eloquent Models

Instance

Create an instance of a class from request parameters:

use Nacoma\Payloads\Hydrators\Attributes\MakeInstance;

new class {
    #[MakeInstance]
    public SomeClass $someClass1;

    #[MakeInstance(SomeOtherConcrete::class)]
    public SomeClass $someClass2;
};

Arrays & Collections

The MakeList plugin assumes that the type is either an array or some type of collection that takes an array of items as the constructor parameter.

use Nacoma\Payloads\Hydrators\Attributes\MakeList;
use Illuminate\Support\Collection;

new class {
    /**
     * @var SomeClass[] 
     */
    #[MakeList(SomeClass::class)]
    public array $items1;

    #[MakeList(SomeClass::class)]
    public Collection $item2;
};

Models

Fetch a model from the database using FindModel.

use Nacoma\Payloads\Hydrators\Attributes\FindModel;

new class {
    #[FindModel]
    public User $user;
};

class UserController extends Controller {
    public function update(User $user, UpdateUser $payload)
    {
        dump($payload->country->id);
    }
