Launch Demo →

// No more getters/setters!
$user->name = 'John Doe';    // ✅ Direct assignment
echo $user->email;           // ✅ Direct access

// One attribute for all types - clean and consistent
#[Property(type: 'string', required: true, validation: 'email')]
public string $email;

#[Property(type: 'enum', class: UserStatus::class)]
public UserStatus $status;

#[Property(type: 'nested', class: AddressDTO::class)]
public AddressDTO $address;

// Rules generated automatically from attributes!
$rules = UserDTO::rules();
// ['email' => 'required|string|email', 'name' => 'required|string']

// Transform data before casting
#[Property(type: 'string', transform: [TrimTransformer::class, LowercaseTransformer::class])]
public string $email;  // '  [email protected]  ' becomes '[email protected]'
