Symfony Flex in Action

This talk was hold on October 27th with Christian Flothmann (@xabbuh) at SymfonyLive in Berlin.

Symfony Flex is a revolution in the world of Symfony and changes the way of building applications. A developer needs to focus more on dependencies, but can easily increase productivity and lower the footprint of an application. We accompanied Symfony on the way to the new Flex era and will give you concrete examples how application development now looks like and explain the key concepts.

8. SensioLabs Symfony Flex
9. Why Flex?
10. applications based on Standard Edition
11. symfony/asset symfony/browser-kit symfony/cache symfony/config symfony/console symfony/css-selector symfony/dependency-injection symfony/debug symfony/debug-bundle symfony/doctrine-bridge symfony/dom-crawler depends on symfony/symfony
12. massive dependency graph
13. hard to customize
14. redundant steps to install bundles
15. Flex to the rescue!
16. start clean
17. composition over inheritance
18. know your dependencies
19. automation
20. The Schedule
21. Symfony Flex can already be used
22. We are here
23. Symfony 3.4 end of November
24. Symfony 3.4 = Symfony 3.3 + new features + new deprecations
25. Symfony 4 at the same time
26. Symfony 4.0 = Symfony 3.4 - deprecated features
27. Symfony 4 != Flex
28. Flex usable with Symfony 3.3
29. Symfony 4 usable without Flex
30. PHP Requirements Flex 7.0.8 Symfony 4 7.1.3
31. SensioLabs Hands on
32. Installation
33. Symfony Installer
34. Flex is a Composer Plugin
35. Hooks into Composer‘s lifecycle
36. $ composer create-project \ symfony/skeleton my-app New applications $ composer create-project \ symfony/skeleton my-app
37. Symfony 4 Beta $ composer create-project \ symfony/skeleton:^4.0@beta my-app
38. Standard Edition
39. Anatomy
40. Initial size decreases
41. $ symfony new my-app $ du –sh my-app 53M my-app $ cloc my-app 652.336 LOC Standard Edition
42. $ composer create symfony/skeleton my-app $ du –sh my-app 14M my-app $ cloc my-app 135.726 LOC Flex
