4. A CONTROLLER IS A PHP CALLABLE YOU CREATE THAT TAKES INFORMATION FROM THE HTTP REQUEST AND CREATES AND RETURNS AN HTTP RESPONSE (AS A SYMFONY RESPONSE OBJECT). The Symfony Book SYMFONY CONTROLLERS
5. SYMFONY CONTROLLERS, NOWADAYS
6. SYMFONY CONTROLLERS TYPICAL CONTROLLER
7. SYMFONY CONTROLLERS FUNCTION AS CONTROLLER
8. SYMFONY CONTROLLERS INVOKABLE CLASS AS CONTROLLER
9. SYMFONY CONTROLLERS INVOKABLE CLASS: HOW DOES IT WORK?
10. SYMFONY CONTROLLERS CONTAINER AWARE CONTROLLER (E.G. FRAMEWORKBUNDLE’S CONTROLLER)
11. SYMFONY CONTROLLERS CONTROLLER AS A SERVICE
12. SYMFONY CONTROLLERS CONTROLLER AS A SERVICE
13. SYMFONY CONTROLLERS INVOKABLE CONTROLLER AS A SERVICE
14. AUTOWIRED SERVICES
15. AUTOWIRING ALLOWS TO REGISTER SERVICES IN THE CONTAINER WITH MINIMAL CONFIGURATION. IT AUTOMATICALLY RESOLVES THE SERVICE DEPENDENCIES BASED ON THE CONSTRUCTOR'S TYPEHINT WHICH IS USEFUL IN THE FIELD OF RAPID APPLICATION DEVELOPMENT, WHEN DESIGNING PROTOTYPES IN EARLY STAGES OF LARGE PROJECTS. IT MAKES IT EASY TO REGISTER A SERVICE GRAPH AND EASES REFACTORING. The Symfony Book AUTOWIRED SERVICES

17. DUNGLAS ACTION BUNDLE
18. DUNGLASACTIONBUNDLE ALLOWS TO CREATE REUSABLE, FRAMEWORK AGNOSTIC AND EASY TO UNIT TEST ACTION CLASSES. github.com/dunglas/DunglasActionBundle TEXTE
19. DUNGLASACTIONBUNDLE INTRODUCTION ▸ Replacement for the controller layer (controllers, commands, event listeners…) of Symfony ▸ Controllers and commands automatically registered as services ▸ Autowiring enabled: their dependencies are explicitly injected - you don’t need to configure your services anymore!! ▸ Only 209 lines of code (+ some patches to Symfony) ▸ 150+ stars on GitHub
20. DUNGLASACTIONBUNDLE INSTALL composer require dunglas/action-bundle
21. DUNGLASACTIONBUNDLE USAGE (CONTROLLER)
22. NO CONFIGURATION REQUIRED TO INJECT DEPENDENCIES! TEXTE
23. AUTOWIRED SERVICES EXAMPLE
24. DUNGLASACTIONBUNDLE USAGE (COMMAND)
25. DUNGLASACTIONBUNDLE MORE? ▸ Also support Event Listeners ▸ Configuration to register your own types of classes ▸ Can automatically add tags to registered classes ▸ 100% compatible with existing libraries and bundles (including SensioFrameworkExtraBundle) ▸ Will be included in API Platform v2
26. THE ADR PATTERN
27. THE ADR PATTERN INTRODUCTION ▸ Stand for Action-Domain-Responder ▸ Web-specific refinement of Model-View-Controller https://github.com/pmjones/adr
28. THE ADR PATTERN DETAILS ▸ Action: logic that connects the Domain and Responder. Uses the request input to interact with the Domain, and passes the Domain output to the Responder. ▸ Domain: logic to manipulate the domain, session, application, and environment data, modifying state and persistence as needed. ▸ Responder: logic to build an HTTP response or response description. It deals with body content, templates and views, headers and cookies, status codes, and so on. Source: https://github.com/pmjones/adr

30. AN ADR IMPLEMENTATION USING DUNGLASACTIONBUNDLE ACTION
31. AN ADR IMPLEMENTATION USING DUNGLASACTIONBUNDLE RESPONDER
32. DUNGLASACTIONBUNDLE THE ROAD TO REUSABLE AND CROSS FRAMEWORK ACTIONS ▸ Don’t depend of FrameworkBundle features ▸ Use PSR-7 instead of HttpFoundation: https:// dunglas.fr/2015/07/slides-using-psr-7-with- symfony/ ▸ Don’t use annotations (prefer XML or YAML for routing)
