LE REPOSITORY PATTERNS AVEC LARAVEL 10 + DTO

Voici un exemple d’implémentation du pattern Repository avec des DTO pour un CRUD User dans Laravel 10 PHP 8:

Créez une interface UserRepository qui définit les méthodes CRUD nécessaires pour manipuler les utilisateurs: php Copy code interface UserRepository { public function findAll(): array; public function findById(int $id): ?UserDTO; public function create(UserDTO $userDTO): UserDTO; public function update(int $id, UserDTO $userDTO): UserDTO; public function delete(int $id): void;} Créez une implémentation concrète du UserRepository appelée EloquentUserRepository qui utilise les modèles Eloquent pour effectuer les opérations CRUD: php Copy code class EloquentUserRepository implements UserRepository { public function findAll(): array { return User::all()->map(fn(User $user) => $user->toDTO())->toArray(); }

 1public function findById(int $id): ?UserDTO {
 2    $user = User::find($id);
 3    return $user ? $user->toDTO() : null;
 4}
 5
 6public function create(UserDTO $userDTO): UserDTO {
 7    $user = new User($userDTO->toArray());
 8    $user->save();
 9    return $user->toDTO();
10}
11
12public function update(int $id, UserDTO $userDTO): UserDTO {
13    $user = User::findOrFail($id);
14    $user->fill($userDTO->toArray());
15    $user->save();
16    return $user->toDTO();
17}
18
19public function delete(int $id): void {
20    User::destroy($id);
21}
 1public function findById(int $id): ?UserDTO {
 2    $user = User::find($id);
 3    return $user ? $user->toDTO() : null;
 4}
 5
 6public function create(UserDTO $userDTO): UserDTO {
 7    $user = new User($userDTO->toArray());
 8    $user->save();
 9    return $user->toDTO();
10}
11
12public function update(int $id, UserDTO $userDTO): UserDTO {
13    $user = User::findOrFail($id);
14    $user->fill($userDTO->toArray());
15    $user->save();
16    return $user->toDTO();
17}
18
19public function delete(int $id): void {
20    User::destroy($id);
21}

} Créez une classe UserDTO qui encapsule les données de l’utilisateur: php Copy code class UserDTO { public function __construct( public string $name, public string $email, public ?string $password = null ) {}

 1public static function fromArray(array $data): UserDTO {
 2    return new self(
 3        $data['name'],
 4        $data['email'],
 5        $data['password'] ?? null
 6    );
 7}
 8
 9public function toArray(): array {
10    return [
11        'name' => $this->name,
12        'email' => $this->email,
13        'password' => $this->password,
14    ];
15}
 1public static function fromArray(array $data): UserDTO {
 2    return new self(
 3        $data['name'],
 4        $data['email'],
 5        $data['password'] ?? null
 6    );
 7}
 8
 9public function toArray(): array {
10    return [
11        'name' => $this->name,
12        'email' => $this->email,
13        'password' => $this->password,
14    ];
15}

} Utilisez le UserRepository dans votre contrôleur pour manipuler les utilisateurs: php Copy code class UserController extends Controller { private UserRepository $userRepository;

 1public function __construct(UserRepository $userRepository) {
 2    $this->userRepository = $userRepository;
 3}
 4
 5public function index() {
 6    $users = $this->userRepository->findAll();
 7    return view('users.index', compact('users'));
 8}
 9
10public function create() {
11    return view('users.create');
12}
13
14public function store(Request $request) {
15    $userDTO = UserDTO::fromArray($request->input());
16    $this->userRepository->create($userDTO);
17    return redirect()->route('users.index');
18}
19
20public function edit(int $id) {
21    $user = $this->userRepository->findById($id);
22    return view('users.edit', compact('user'));
23}
24
25public function update(Request $request, int $id) {
26    $userDTO = UserDTO::fromArray($request->input());
27    $this->userRepository->update($id, $userDTO);
28    return redirect()->route('users.index');
29}
30
31public function delete(int $id) {
32    $this->userRepository->delete($id);
33    return redirect()->route(‘users.index’);
 1public function __construct(UserRepository $userRepository) {
 2    $this->userRepository = $userRepository;
 3}
 4
 5public function index() {
 6    $users = $this->userRepository->findAll();
 7    return view('users.index', compact('users'));
 8}
 9
10public function create() {
11    return view('users.create');
12}
13
14public function store(Request $request) {
15    $userDTO = UserDTO::fromArray($request->input());
16    $this->userRepository->create($userDTO);
17    return redirect()->route('users.index');
18}
19
20public function edit(int $id) {
21    $user = $this->userRepository->findById($id);
22    return view('users.edit', compact('user'));
23}
24
25public function update(Request $request, int $id) {
26    $userDTO = UserDTO::fromArray($request->input());
27    $this->userRepository->update($id, $userDTO);
28    return redirect()->route('users.index');
29}
30
31public function delete(int $id) {
32    $this->userRepository->delete($id);
33    return redirect()->route(‘users.index’);

} }
