On user registration, we would like to… - Hash the user’s submitted password - Create a User record and save it to the database - Send a welcome email with a validation link - Share the user’s profile with Intercom - Save the returned Intercom ID to the database

Message class RegisterUser { private readonly PasswordHasherInterface $passwordHasher; public function __construct( private readonly PasswordHasherFactoryInterface $passwordHasherFactory, private readonly UserRepository $userRepository, private readonly UserEmailVerifier $userEmailVerifier, private readonly IntercomClient $intercomClient, ) { $this->passwordHasher = $this->passwordHasherFactory->getPasswordHasher(User::class); } public function registerUser( string $email, string $password, Gender|string $gender, string $fullName, ?string $country = null, DateTimeInterface|string|null $birthdate = null, ): User { // ... } }

Message class RegisterUser { // ... public function registerUser(...): User { // ... $hashedPassword = $this->passwordHasher->hash($password); $user = User::register( $email, $hashedPassword, $gender, $fullName, $country, $birthdate, ); $this->userRepository->save($user); $this->userEmailVerifier->sendEmailConfirmation($user); $intercomId = $this->intercomClient->createUser($user); $user->setIntercomId($intercomId->id); $this->userRepository->save($user); return $user; } }

Message class UserEmailVerifier { // ... public function sendEmailConfirmation(User $user): void { $signatureComponents = $this->verifyEmailHelper->generateSignature( 'app_verify_user_email', (string) $user->getId(), $user->getEmail(), ['id' => (string) $user->getId()], ); $email = new TemplatedEmail() ->from(new Address('noreply@example.com', 'DevCon 2025')) ->to(new Address($user->getEmail(), $user->getFullName())) ->subject('Please Confirm your Email') ->htmlTemplate('email/user_confirmation_email.html.twig'); $context = $email->getContext(); $context['greetings'] = $user->getFullName(); $context['signedUrl'] = $signatureComponents->getSignedUrl(); $context['expiresAtMessageKey'] = $signatureComponents->getExpirationMessageKey(); $context['expiresAtMessageData'] = $signatureComponents->getExpirationMessageData(); $email->context($context); $this->mailer->send($email); } }

Message final class IntercomProxyClient implements IntercomClient { // ... public function __construct( private readonly IntercomContacts $intercomContacts, ) { } public function createUser(User $user): IntercomContact { // Make a POST HTTP request to Intercom REST API $contact = $this->intercomContacts->create([ 'type' => 'user', 'external_id' => (string) $user->getId(), 'email' => $user->getEmail(), 'name' => $user->getFullName(), 'signed_up_at' => $user->getCreatedAt()->getTimestamp(), 'custom_attributes' => [ 'gender' => $user->getGender()->value, 'birthdate' => $user->getBirthdate()?->format('Y-m-d'), 'country' => $user->getCountry(), 'email_verified_at' => $user->getEmailVerifiedAt()?->getTimestamp(), ], ]); return IntercomContact::fromStdClass($contact); } }

Although this code works, it may have issues at some point. - Latency (because of IOs / network) - Sending the confirmation email may fail - Intercom API may be not responding - End user can “feel” the page is not responding fast enough

Messenger Core Concepts https://unsplash.com/@hungngng

“ Messenger provides a message bus with the ability to send messages and then handle them immediately in your application or send them through transports (e.g. queues) to be handled later. ” — Symfony Official Doc.

# config/packages/messenger.yaml framework: messenger: # Uncomment this to send failed messages to this transport for later handling. # failure_transport: failed transports: # https://symfony.com/doc/current/messenger.html#transport-configuration # async: '%env(MESSENGER_TRANSPORT_DSN)%' # failed: 'doctrine://default?queue_name=failed' # sync: 'sync://' routing: # Route your messages to the transports # 'App\Message\YourMessage': async Installation $ composer require symfony/messenger

A message is a data structure that holds the needed information for the message handler to process that message later. It mainly takes the shape of a pure PHP object that has the sole requirement of being serializable.

Message namespace App\User\Message; use Symfony\Component\Messenger\Attribute\AsMessage; use Symfony\Component\Uid\Uuid; #[AsMessage] final readonly class SendWelcomeEmailMessage { public function __construct( private string $userId, ) { } public function getUserId(): Uuid { return Uuid::fromString($this->userId); } }

Message namespace App\Intercom\Message; use Symfony\Component\Messenger\Attribute\AsMessage; use Symfony\Component\Uid\Uuid; #[AsMessage] final readonly class SyncIntercomUserContactMessage { public function __construct( private string $userId, ) { } public function getUserId(): Uuid { return Uuid::fromString($this->userId); } }

The message handler is a callable that is responsible for processing the message it receives. It mainly takes the shape of an invokable PHP service class.

Message namespace App\User\MessageHandler; use App\Repository\UserRepository; use App\User\Message\SendWelcomeEmailMessage; use App\User\UserEmailVerifier; use Symfony\Component\Messenger\Attribute\AsMessageHandler; #[AsMessageHandler] final class SendWelcomeEmailMessageHandler { public function __construct( private readonly UserRepository $userRepository, private readonly UserEmailVerifier $userEmailVerifier, ) { } public function __invoke(SendWelcomeEmailMessage $message): void { $user = $this->userRepository->byId($message->getUserId()); $this->userEmailVerifier->sendEmailConfirmation($user); } }

Message namespace App\Intercom\MessageHandler; // ... #[AsMessageHandler] final class SyncIntercomUserContactMessageHandler { public function __construct( private readonly UserRepository $userRepository, private readonly IntercomClient $intercomClient, ) { } public function __invoke(SyncIntercomUserContactMessage $message): void { $user = $this->userRepository->byId($message->getUserId()); if ((string) $user->getIntercomId() !== '') { $this->intercomClient->updateUser($user); return; } $contact = $this->intercomClient->createUser($user); $user->setIntercomId($contact->id); $this->userRepository->save($user); } }

The message bus is a service object that is responsible for conveying the message to its message handler. To do so, it delegates to a transport layer and a series of middleware to manipulate the message.

Message interface MessageBusInterface { /** * Dispatches the given message. * * @throws ExceptionInterface */ public function dispatch(object $message, array $stamps = []): Envelope; }

Message final class RegisterUserController extends AbstractController { public function __construct( private readonly RegisterUser $registerUser, private readonly MessageBusInterface $messageBus, ) { } #[Route('/registration', name: 'app_register_user', methods: ['GET', 'POST'])] public function __invoke(Request $request): Response { $form = $this->createForm(UserRegistrationType::class); $form->handleRequest($request); if ($form->isSubmitted() && $form->isValid()) { /** @var UserRegistration $data */ $data = $form->getData(); $user = $this->registerUser->registerUser(...); $this->messageBus->dispatch(new SendWelcomeEmailMessage((string) $user->getId())); $this->messageBus->dispatch(new SyncIntercomUserContactMessage((string) $user->getId())); return $this->redirectToRoute('app_confirm_user_registration'); } return $this->render('register_user/index.html.twig', [ 'form' => $form->createView(), ]); } }

The transport is the piece of software that is responsible for communicating with a message broker or any third parties. It provides layers for both sending and receiving a message.

Handling Messages Asynchronously https://unsplash.com/@andriklangfield

Why do you sometimes need async tasks? 📨 Sending a notification 🗂 Updating a search index ⚙ Syncing data with external tools 📋 Computing data or documents (reports, archives, etc.) 🎥 Processing large pieces of documents

Message # .env ###> symfony/messenger ### # Choose one of the transports below # MESSENGER_TRANSPORT_DSN=amqp://guest:guest@localhost:5672/%2f/messages # MESSENGER_TRANSPORT_DSN=redis://localhost:6379/messages MESSENGER_TRANSPORT_DSN=doctrine://default?auto_setup=0 ###< symfony/messenger ### # config/packages/messenger.yaml framework: messenger: transports: async: '%env(MESSENGER_TRANSPORT_DSN)%'

Envelope & Stamps https://unsplash.com/@polarmermaid

Each message is wrapped into an envelope, on which any number of stamps can be sticked to in order to attach some useful metadata to it. ✉

Message $message = new SyncIntercomUserContactMessage((string) $user->getId()); // Shorthand syntax $this->messageBus->dispatch($message, [ DelayStamp::delayFor(new DateInterval('PT20S')), new ValidationStamp(['user_registration']), // + any other stamps ]); // Expanded syntax $this->messageBus->dispatch( new Envelope($message)->with( DelayStamp::delayFor(new DateInterval('PT20S')), new ValidationStamp(['user_registration']), // + any other stamps ), );

Middleware https://unsplash.com/@purzlbaum

Middleware are pieces of software that sit around the bus, so that they can access any messages and their wrapper (the envelope) while they’re being dispatched. They are cross cutting concerns applicable throughout the application and affecting the entire message bus. Their responsibilities can be any global concern such as logging, validating a message, starting a transaction, ... They are also responsible for calling the next middleware in the chain, which means they can tweak the envelope, by adding stamps to it or even replacing it, as well as interrupt the middleware chain.

Message class ValidationMiddleware implements MiddlewareInterface { public function __construct( private ValidatorInterface $validator, ) { } public function handle(Envelope $envelope, StackInterface $stack): Envelope { $message = $envelope->getMessage(); $groups = null; /** @var ValidationStamp|null $validationStamp */ if ($validationStamp = $envelope->last(ValidationStamp::class)) { $groups = $validationStamp->getGroups(); } $violations = $this->validator->validate($message, null, $groups); if (\count($violations)) { throw new ValidationFailedException($message, $violations, $envelope); } return $stack->next()->handle($envelope, $stack); } }
