The ValidationInterceptor provided by this library helps validating messages posted to predaddy MessageBus. It is based on Symfony Validator component.

Usage

$bus = SimpleMessageBus::builder()
    ->withInterceptors([new ValidatorInterceptor()])
    ->build();

class CreateUser
{
    /**
     * @Assert\Length(min = 3)
     * @Assert\NotBlank
     */
    private $name;

    /**
     * @Assert\Email
     * @Assert\NotBlank
     */
    private $email;

    public function __construct($name, $email)
    {
        $this->name = $name;
        $this->email = $email;
    }

    /**
     * @Assert\True(message = "The user should have a Google Mail account")
     */
    public function isGmailUser()
    {
        return false !== strpos($this->email, '@gmail.com');
    }

    public function __toString()
    {
        return Objects::toStringHelper($this)
            ->add('name', $this->name)
            ->add('email', $this->email)
            ->toString();
    }
}

try {
    $bus->post(new CreateUser('John Doe', '[e-mail]'));
} catch (ValidationException $e) {
    $e->getViolationList();
}

If you use annotation constraints, do not forget to register its namespace:

AnnotationRegistry::registerAutoloadNamespace('Symfony\Component\Validator\Constraint', 'path/to/symfony/library/validator');
