1. FLEX Symfony goes minimal Aleš Šarkanj @alsar Symfony Slovenia user group | 28.11.2017
2. SYMFONY 4.0 What’s new?
3. NO NEW FEATURES Major versions are cleanup versions (after 2.0) Symfony 4.0 = Symfony 3.4 – deprecated features Gradual upgrade 3.x 3.4 remove deprecations 4.0 → → →
4. SYMFONY 3.4 OR 4.0 3.4 is a LTS version (supported until end of 2021) 4.0 requires PHP 7.1
5. Why is Symfony 4.0 so special?
6. PATH TO A BETTER SYMFONY Redefine the perception of the framework
7. SYMFONY IS: “Just for big projects” “An overkill for small projects” “A monolith framework” “Bloated, has to many features” “Is to complex”
8. I DON’T LIKE SYMFONY BECAUSE: It’s full stack. It’s too complicated. I don’t need all the features, I just need something simple.
9. THE MONOLITH FRAMEWORK
10. STARTING A NEW PROJECT
11. DISTRIBUTIONS AS A STARTING POINT A predefined starting point for bootstrapping your project (since version 2.0) A basic project with predefined functionalities It gives you everything “ ” whole symfony/symfony, twig, doctrine, security, web profiler, bundles …
12. REMOVE WHAT YOU DON’T NEED composer remove symfony/swiftmailer-bundle remove it from the kernel remove routing remove configuration
13. ADD WHAT YOU NEED composer require javiereguiluz/easyadmin-bundle add it to the kernel register routes configure bundle
14. A LOT OF MANUAL WORK Basically the same manual procedure for every bundle Copy-paste from bundle README
15. DISTRIBUTIONS ARE A WRONG CONCEPT A standard solution to a non-standard problem
16. SYMFONY GOES MINIMAL
17. REDEFINITION Symfony full stack framework Symfony all purpose framework
18. START SMALL GO BIG Start with a minimal set of features Only get the essential features in the start Some Core functionalities not installed by default “ ” Grow as you need
19. MICRO BY DEFAULT New applications created with Symfony 4 are based on a micro-kernel and contain 70% less code and files than new Symfony 3 apps
20. It’s all about perception
21. WELCOME TO FLEX Evolve your project with ease
22. A NEW WAY TO MANAGE SYMFONY APPS Simple and easy to create any Symfony app Evolve from a simple to a complex app
23. HOW DOES FLEX WORK A Composer plugin Hooks into the require, install and update commands Integration of libraries and bundles through recipes
24. AUTOMATE ALL THE THINGS Install an remove bundles with ease When installing a bundle, Symfony will now configure it automatically with good defaults.
25. NO MORE DISTRIBUTIONS Flex is the default way to manage and develop Symfony 4 applications
26. THE STARTING POINT
27. A minimal Symfony project recommended to create new applications A single starting point for all types of applications $ composer create-project symfony/skeleton demo ^4.0@RC SYMFONY SKELETON
28. SYMFONY SKELETON
29. A SINGLE composer.json FILE { "name": "symfony/skeleton", "minimum-stability": "RC", "require": { "php": "^7.1.3", "symfony/console": "^4.0", "symfony/flex": "^1.0", "symfony/framework-bundle": "^4.0", "symfony/lts": "^4@dev", "symfony/yaml": "^4.0" }, "require-dev": { "symfony/dotenv": "^4.0" }, … }
30. CREATE A NEW PROJECT
31. NEW DIRECTORY STRUCTURE
32. START THE PROJECT WITH 24 dependencies instead of 89 18 services instead of 235
33. REQUIRE WHAT YOU NEED Everything must be explicitly required forms, validation, annotations, security, templating, translations...
34. ADD A PACKAGE
35. REMOVE A PACKAGE
36. PACKAGE NAME ALIASES Short, easy to remember names log, mailer, form, orm, validator, admin... High-quality packages
37. FLEX PACKS Composer meta-package that references a set of related packages (composer.json) Examples: orm-pack, debug-pack, profler-pack, api-pack...
38. orm-pack composer.json { "name": "symfony/orm-pack", "type": "metapackage", "license": "MIT", "description": "A pack for the Doctrine ORM", "require": { "php": "^7.0", "doctrine/orm": "^2.5.11", "doctrine/doctrine-bundle": "^1.6.10", "doctrine/doctrine-migrations-bundle": "^1.3" } }
39. ORM PACK
40. FLEX RECIPES
41. RECIPES Integration of packages and bundles into a Symfony application.
42. twig-bundle manifest.json { "bundles": { "Symfony\\Bundle\\TwigBundle\\TwigBundle": ["all"] }, "copy-from-recipe": { "config/": "%CONFIG_DIR%/", "templates/": "templates/" }, "aliases": ["twig", "template", "templates"] }
43. RECIPE CONFIGURATORS Flex currently implements 8 configurators copy-from-recipe, copy-from-package, bundles, env, container, composer-scripts, gitignore, post-install
44. RECIPE EXAMPLE
45. SYMFONY RECIPE SERVER Central location for recipes: https://symfony.sh Recipe repositories • core (official) https://github.com/symfony/recipes • contrib https://github.com/symfony/recipes-contrib https://symfony.sh
46. FLEX PROS Better DX – only get what you need Automatization Start small, go big Composer plugin
47. FLEX CONS Adapt to the new way New project structure Migration Harder for beginners?
48. MIGRATE YOUR PROJECT
49. FLEX MINIMUM REQUIREMENTS Requires PHP 7.0+ Flex works with Symfony 3.3+
50. HOW TO MIGRATE TO FLEX No migration tool Upgrade guide https://symfony.com/doc/current/setup/flex.html#upgrading-existing-applications-to-flex
51. CONCLUSION Flex changes the way we build Symfony projects Automation of repetitive tasks Opt-in on functionalities “Symfony – The all purpose framework”
