Service Pattern

<?php

declare(strict_types=1);

namespace App\Services;

final readonly class UserService
{
    public function __construct(
        private UserRepositoryInterface $repository,
    ) {}

    public function create(CreateUserDTO $dto): User
    {
        return $this->repository->create($dto->toArray());
    }
}

Dependency Injection

// AppServiceProvider.php
public function register(): void
{
    $this->app->bind(
        UserRepositoryInterface::class,
        UserRepository::class
    );
}
