6. Domain-Driven Design

Tackling the Heart of Software Development

Domain-Driven DesignA methodology which ...

• results in rich domain models

• provides a common language across the project team

• simplify the design of complex applications

FLOW3 is the first PHP framework tailored to Domain-Driven Design

Object Management

FLOW3's take on Dependency Injection

• one of the first PHP implementations(started in 2006, improved ever since)

• object management for the whole lifecycle of all objects

• no unnecessary configuration if information can be gatered automatically (autowiring)

• intuitive use and no bad magical surprises

• fast! (like hardcoded or faster)

namespace Acme\Demo\Controller;

use TYPO3\FLOW3\Mvc\Controller\ActionController;use Acme\Demo\Service\GreeterService;

class DemoController extends ActionController { /** * @var \Acme\Demo\Service\GreeterService */ protected $greeterService;

/** * @param \Acme\Demo\Service\GreeterService */ public function __construct(GreeterService $greeterService) { $this->greeterService = $greeterService; } /** * @param string $name */ public function helloAction($name) { return $this->greeterService->greet($name); }}

Constructor Injection

namespace Acme\Demo\Controller;

use TYPO3\FLOW3\MVC\Controller\ActionController;use Acme\Demo\Service\GreeterService;

class DemoController extends ActionController { /** * @var \Acme\Demo\Service\GreeterService */ protected $greeterService;

/** * @param \Acme\Demo\Service\GreeterService */ public function injectGreeterService(GreeterService $greeterService) { $this->greeterService = $greeterService; } /** * @param string $name */ public function helloAction($name) { return $this->greeterService->greet($name); }}

Setter Injection

namespace TYPO3\Demo\Controller;

use TYPO3\FLOW3\Annotations as FLOW3;use TYPO3\FLOW3\MVC\Controller\ActionController;use Acme\Demo\Service\GreeterService;

class DemoController extends ActionController { /** * @var \TYPO3\Demo\Service\GreeterService * @FLOW3\Inject */ protected $greeterService; /** * @param string $name */ public function helloAction($name) { return $this->greeterService->greet($name); }}
