5. Which
 Symfony version(s)
 are you using? 1.x? 2.x? 3.x? 4.x?
6. What is Symfony 4? A new developer experience On a rock solid foundation From micro-style to monolith and prototypes
7. Wired? Tired? or
8. Symfony
 Encore Webpack Assetic
9. Symfony Local Web Server Built-in
 PHP server
10. Symfony Local Web Server $ symfony server:start -d # open in the browser $ symfony open:local # tail the logs $ symfony server:log
11. • PHP-FPM (concurrent requests) • HTTP 2 • TLS • Local domain names • No dependencies / single binary (MacOS, Linux, and Windows) • Manages background commands (Encore, Messenger, ...) • Consolidated logs (PHP , Web server, app, background commands) • Docker integration (and SymfonyCloud) • Multiple versions of PHP • HTTP Link/pre-load/push support Symfony Local Web Server

13. $ symfony new demo $ symfony new demo --cloud --debug # Want to try Symfony 5.0 (dev version)? $ symfony new demo --version=dev-master Creating a new project
14. Symfony CLI SensioLabs Security Checker
15. $ symfony security:check Does not call
 https://security.symfony.com/ Clones and caches

19. $ symfony new demo # Forms are ❌ disabled as symfony/form is not installed $ composer req form # Forms are automatically ✅ enabled as symfony/form is installed + Auto-configuration + No manual changes + Better performance
20. Third-party
 Bundles with recipes Application
 Bundles
21. $ cat src/Controller/DefaultController.php App vs Bundles src/ is about YOUR code
22. Environment Variables Class Constants Parameters n/a
23. Parameter Class constant Environment variable Can be provided
 by a third party ("standard") ❌ ❌ ✅ Can be changed
 without cache:clear ❌ ❌ ✅ Easy to use in code ❌ ✅ Can be changed
 without redeploy ❌ ✅ Can be different
 in dev and prod ✅ ❌ ✅ Can be stored
 outside of a Git repo ✅ ❌ ✅ Rich type support via processors Example Configure

 infrastructure
24. Container Auto-discovery Auto-configuration Auto-wiring Service
 Configuration
25. $ composer req twig Adding Twig + Controller as a service + No manual changes + No configuration + Auto-wiring Productivity++
26. Never define
 your service again*
27. Maker
 Bundle Generator
 Bundle
28. $ ./bin/console list make Symfony Maker Bundle
29. $ ./bin/console make:controller DefaultController Symfony Maker Bundle
30. $ cat src/Controller/DefaultController.php Symfony Maker Bundle Annotations Everything in one file
31. Adding a Twig Extension Where do I store the Twig extension class? Which file do I need to change to register it? Which tag do I need to use? How do I declare a tag in YAML? Which interface/class do I need to implement/ extend? It’s too complex. What about doing it the dirty way and do it in the controller instead? hmm, ok
32. $ ./bin/console make:twig-extension Adding a Twig Extension Add your logic in the generated class… DONE!
33. Full Automation works for… • Twig extensions • Event listeners • Doctrine entities/repositories • Commands • Voters • Registration form system • …
34. Twig
 Templates PHP
 Templates
35. You can use PHP templates But Twig benefits
 from a fully maintained integration
36. Symfony
 Mailer Swiftmailer
37. A great example of
 how we leverage
 the "new" Symfony infrastructure
38. I want to send emails
 from my controller
39. $ composer req symfony/mailer Sending emails use Symfony\Component\Mailer\MailerInterface; public function index(MailerInterface $mailer) { $mailer->send( (new Email()) ->from('fabien@symfony.com') ->to('fabien@symfony.com') ->subject('Some subject') ->text('Some text...') ); MAILER_DSN=smtp://localhost + No configuration + No manual changes + Auto-wiring + Env vars
40. I want to send rich emails
 from my controller
41. Sending emails use Symfony\Component\Mailer\MailerInterface; public function index(MailerInterface $mailer) { $mailer->send( (new TemplatedEmail()) ->from('fabien@symfony.com') ->to('fabien@symfony.com') ->subject('Some subject') ->htmlTemplate('@emails/welcome.html.twig') ->context([ 'city' => 'Tunis' ]) );
42. I want to send rich and responsive emails
 from my controller
43. $ composer req twig/inky-extension twig/cssinliner-extension Sending emails {% apply inky|inline_css(source("@zurb/stylesheets/main.css")) %} <container> <row class="header"> <columns> <spacer size="16"></spacer> <h4 class="text-center">Symfony Connect</h4> </columns> </row> <row> <columns> <spacer size="32"></spacer> <center><img width="100px" src="{{ email.image("@images/symfony.png") }}"></center> <spacer size="16"></spacer> <h1 class="text-center">Forgot Your Password?</h1> <spacer size="16"></spacer> <p class="text-center">It happens. Click the link below to reset it.</p> <button class="large expand" href="#">Reset Password</button> <hr/> <p><small><center><a href="#">unsubscribe here</a>.</small></center></p> </columns> </row> </container> {% endapply %}
44. I want to send rich and responsive emails
 from my controller
 via my provider's API
45. $ composer req mailgun-mailer MAILER_DSN=http://$MAILGUN_KEY:$MAILGUN_DOMAIN@mailgun Sending emails Amazon SES Google Gmail Mandrill Mailgun Postmark Sendgrid
46. I want to send rich and responsive emails
 from my controller
 via my provider's API
 asynchronously
47. $ composer req messenger framework: messenger: transports: email: "doctrine://default" routing: Symfony\Component\Mailer\Messenger\SendEmailMessage: email $ ./bin/console messenger:consume $ symfony run -d ./bin/console messenger:consume -vv Sending emails Go to the background
48. $ symfony server:status $ symfony server:log Sending emails
49. I want to send rich and responsive emails
 from my controller
 via my provider's API
 asynchronously with AMQP
50. At this point, think about
 how you would do it
 with Symfony 3.4 Here, we have not written
 a single line of code
 and barely changed the configuration
51. We are only using Symfony components
52. I want to send rich and responsive emails
 from my controller
 via my provider's API
 asynchronously with AMQP
53. framework: messenger: transports: email: "%env(RABBITMQ_DSN)%" routing: Symfony\Component\Mailer\Messenger\SendEmailMessage: email $ docker-compose up -d Sending emails rabbitmq: image: rabbitmq ports: - 5672 docker-compose.yml Symfony Local Web Server
 Env vars "auto-wiring" Local port is random
54. I want to send rich and responsive emails
 from my controller
 via my provider's API
 asynchronously with AMQP
 and manage failures gracefully
55. $ composer req symfony/sendgrid-mailer MAILER_DSN=http://key:domain@mailgun || http://key@sendgrid Sending emails
56. framework: messenger: transports: email: dsn: "%env(RABBITMQ_DSN)%" retry_strategy: max_retries: 3 routing: Symfony\Component\Mailer\Messenger\SendEmailMessage: email Sending emails
57. framework: messenger: failure_transport: failed transports: failed: 'doctrine://default?queue_name=failed' email: dsn: "%env(RABBITMQ_DSN)%" retry_strategy: max_retries: 3 routing: Symfony\Component\Mailer\Messenger\SendEmailMessage: email $ symfony server:log $ ./bin/console messenger:failed:show $ ./bin/console messenger:failed:retry Sending emails
58. Sending emails
59. I want to send rich and responsive emails
 from my controller
 via my provider's API
 asynchronously with AMQP
 and manage failures gracefully
 without Docker
60. $ symfony project:init $ symfony deploy $ symfony log --worker=send_emails all Sending emails rabbitmq: type: rabbitmq:3.7 disk: 1500 .symfony/services.yaml .symfony.cloud.yaml runtime: extensions: [ "amqp" ] relationships: rabbitmq: "rabbitmq:rabbitmq" workers: send_emails: commands: start: | set -x -e (>&2 symfony-deploy) bin/console messenger:consume -vv email Production ready
61. $ symfony tunnel:open Sending emails Symfony Local Web Server
 Env vars "auto-wiring" .symfony.cloud.yaml relationships: rabbitmq: "rabbitmq:rabbitmq" Development ready framework: messenger: transports: email: "%env(RABBITMQ_DSN)%"
62. Experience The new Components: http-client, messenger, mailer, container, ... Concepts: Flex, auto-configuration, env vars, ... Tools: Symfony CLI, SymfonyCloud, Docker
63. is a fantastic set of low-level building blocks
 that you can assemble to develop
 powerful high-level features easily
64. What about the future? Nobody knows, it depends on you 
 ... so, what have you done so far for Symfony 4.4?
65. HTTP errors without Twig Important for API-only applications
66. PHP 7.4 preload support Performance FTW
67. A better Security component? https://github.com/symfony/symfony/issues/30914
 https://github.com/symfony/symfony/issues/30765
68. ... to be continued
69. Thank you and see you soon!
