The Evolution of Symfony: Now and to the Future!

With the release of 6.2, Symfony will contain somewhere near *500* new features from just the past 12 months! Wow!

And, while many of these are small, the landscape of *how* Symfony apps are developed continues to evolve. In this talk, we'll look at some of the most important changes, from new dependency injection attributes, framework-extra bundle features in Symfony, Symfony UX, testing, and more! Basically... a quick catch-up on 12 months, *thousands* of commits, and hundreds of releases across numerous repositories. Let's go!

4. The Latest in Mouse Animation @weaverryan (modernization: PHP 8+ & Symfony)
5. PHP 8.0 (2 years old) - Attributes - Property Promotion - Named Arguments - $null?->safeOp() - Trailing arg commas - Stringable @weaverryan PHP 8.1 (1 year old) - Enums - Readonly props - Callable syntax - New in initializers PHP 8.2 (-1 week) - Readonly classes
6. Adventure #1 Entities @weaverryan
7. /** @ORM\Entity(repositoryClass=UserRepository::class) */ class User implements UserInterface, PasswordAuthenticatedUserInterface { /** * @ORM\Id * @ORM\GeneratedValue * @ORM\Column(type="integer") */ private $id; /** @ORM\Column(type="string", unique=true) */ private $email; /** @ORM\Column(type="json") */ private $roles = []; /** @ORM\ManyToOne(targetEntity=Address::class) */ private $address; }
8. #[ORM\Entity(repositoryClass: UserRepository::class)] class User implements UserInterface, PasswordAuthenticatedUserInterface { #[ORM\Id] #[ORM\GeneratedValue] #[ORM\Column(type: Types::INTEGER)] private $id; #[ORM\Column(type: Types::STRING, unique: true)] private $email; #[ORM\Column(type: Types::JSON)] private $roles = []; #[ORM\ManyToOne(targetEntity: Address::class)] private $address; }
9. #[ORM\Entity(repositoryClass: UserRepository::class)] class User implements UserInterface, PasswordAuthenticatedUserInterface { #[ORM\Id] #[ORM\GeneratedValue] #[ORM\Column(type: Types::INTEGER)] private ?int $id = null; #[ORM\Column(type: Types::STRING, unique: true)] private ?string $email = null; #[ORM\Column(type: Types::JSON)] private array $roles = []; #[ORM\ManyToOne(targetEntity: Address::class)] private ?Address $address = null; }
10. #[ORM\Entity(repositoryClass: UserRepository::class)] class User implements UserInterface, PasswordAuthenticatedUserInterface { #[ORM\Id] #[ORM\GeneratedValue] #[ORM\Column()] private ?int $id = null; #[ORM\Column(unique: true)] private ?string $email = null; #[ORM\Column] private array $roles = []; #[ORM\ManyToOne()] private ?Address $address = null; }
11. Adventure #2 Controllers @weaverryan
12. /** * @Route("/products/edit/{id}", name="product_edit") * @IsGranted("product_edit", subject="product") */ public function edit(Product $product) { }
13. #[Route('/products/edit/{id}', name: 'product_edit')] #[IsGranted('product_edit', subject: 'product')] public function edit(Product $product): Response { }
14. So long, and thanks for all the fi sh
15. #[Route('/products/edit/{id}')] public function edit(Product $product): Response { $user = $this->getUser(); }
16. #[Route('/products/edit/{id}')] public function edit(Product $product, #[CurrentUser] User $user) { } * #[CurrentUser] is not new. But playing nice with the "entity resolver" IS new
17. Adventure #3 Services @weaverryan
18. class PlotFactory { private CharacterGenerator $characterGenerator; private ConflictCreator $conflictCreator; private LoveableSidekickBuilder $sidekickBuilder; public function __construct( CharacterGenerator $characterGenerator, ConflictCreator $conflictCreator, LoveableSidekickBuilder $sidekickBuilder, ) { $this->characterGenerator = $characterGenerator; $this->conflictCreator = $conflictCreator; $this->sidekickBuilder = $sidekickBuilder; } } 🥱
19. class PlotFactory { public function __construct( private CharacterGenerator $characterGenerator, private ConflictCreator $conflictCreator, private LoveableSidekickBuilder $sidekickBuilder, ) { } } Property Promotion!
20. class PlotFactory { public function __construct( private readonly CharacterGenerator $characterGenerator, private readonly ConflictCreator $conflictCreator, private readonly LoveableSidekickBuilder $sidekickBuilder, ) { } } Hipster properties
21. One of Symfony's Goals: Keep you working on YOUR code @weaverryan
22. class PlotFactory { public function __construct( private bool $isDebug, private LoaderInterface $twigLoader, ) { } } Non-autowireable args
23. services: # ... App\PlotFactory: arguments: $isDebug: '%kernel.debug%' $twigLoader: '@twig.loader' Go to a YAML fi le??
24. class PlotFactory { public function __construct( private bool $isDebug, private LoaderInterface $twigLoader, ) { } } #[Autowire('%kernel.debug%')] #[Autowire(service: 'twig.loader')]
25. Another need for YAML Tags that don't work with autocon fi guration @weaverryan
26. class MovieCreditsListener { public function onKernelRequest(RequestEvent $event) { } }
27. services: # ... App\MovieCreditsListener: tags: - name: 'kernel.event_listener' event: 'request.event' method: 'onKernelRequest'
28. #[AutoconfigureTag('kernel.event_listener', [ 'event' => RequestEvent::class, 'method' => 'onKernelRequest', ])] class MovieCreditsListener { public function onKernelRequest(RequestEvent $event) { } }
29. #[AsEventListener(RequestEvent::class, 'onKernelRequest')] class MovieCreditsListener { public function onKernelRequest(RequestEvent $event) { } }
30. #[AsEntityListener(Events::prePersist, entity: User::class)] class UserEntityListener { public function prePersist(User $user) { } }
31. #[AsEventListener(RequestEvent::class, 'onKernelRequest')] #[AsCommand(name: 'debug:form', description: '...')] #[AsController] #[AsMessageHandler] #[AsRoutingConditionService] #[AsEntityListener(Events::prePersist, entity: User::class)]
32. Any YAML left? Service Decoration @weaverryan
33. class DecoratedRouter implements RouterInterface { public function __construct( private RouterInterface $router, private LoggerInterface $logger ) { } public function generate(string $name, array $parameters = []) { $this->logger->info('Generating route', [ 'name' => $name, ]); return $this->router->generate($name, $parameters); } }
34. services: # ... App\DecoratedRouter: decorates: 'router'
35. #[AsDecorator(decorates: 'router')] class DecoratedRouter implements RouterInterface { public function __construct( private RouterInterface $router, private LoggerInterface $logger ) { } public function generate(string $name, array $parameters = []) { $this->logger->info('Generating route', [ 'name' => $name, ]); return $this->router->generate($name, $parameters); } }
36. This is the way @weaverryan
37. Bounty Hunting for Bugs @weaverryan (Debugging improvements)
38. php bin/console mailer:test ryan@symfonycasts.com
39. php bin/console messenger:failed:show --class-filter=MyClass php bin/console messenger:failed:show --stats php bin/console messenger:count
40. php bin/console debug:container ConflictCreator
41. Completely Redesigned: Web Debug Toolbar & Pro fi ler
45. Bounty: Spoils of Hard Work @weaverryan (New Goodies)
46. #[Route('/products/edit/{id}', name: 'product_edit')] public function editProduct(Product $product): Response { $form = $this->createForm(ProductFormType::class, $product); // ... return $this->render('product/edit.html.twig', [ 'form' => $form, ]); } $this->renderForm() $form->createView() ❌ ❌ 422 status code ✅
47. class PlotFactory { public function __construct( private HeavyDependency $heavyDependency ) { } } #[Autoconfigure(lazy: true)]
48. #[Route('/movie/create', name: 'create_movie')] public function createMovieAction(PlotFactory $plotFactory) { dump($plotFactory); // ... }
49. #[Route('/movie/create', name: 'create_movie')] public function createMovieAction(PlotFactory $plotFactory) { if ($someRareCondition) { $plotFactory->rewritePlot(); } // ... }
50. #[Route('/register')] public function register(Security $security): Response { // ... // ... } $security->login($user, 'form_login');
51. #[Route('/something')] public function something(Security $security): Response { // ... $security->logout(validateCsrfToken: true); // ... }
52. security: # ... main: # ... access_token: token_handler: App\Security\AccessTokenHandler
53. class AccessTokenHandler implements AccessTokenHandlerInterface { public function getUserIdentifierFrom(string $token): string { $accessToken = $this->repository->findOneByValue($token); if (null === $accessToken || !$accessToken->isValid()) { throw new BadCredentialsException('Invalid credentials.'); } return $accessToken->getUserId(); } }
