This library is design to help you to build your application with a Domain Design Development approach.

It is well integrated with:

• Symfony >= 3.3
• ApiPlatform >= 2.1
• Doctrine >=2.5

But you can use it with any PHP project.

Here are some slides that explain how we get there.

Domain Events:

• Domain event dispatcher
• Injection of the dispatcher in Doctrine entities
• Symfony serializer integration

composer require biig/domain

class YourModel extends DomainModel
{
    public const CREATION = 'creation';
    public function __construct()
    {
        $this->dispatch(self::CREATION, new DomainEvent($this));
    }
}

class DomainRule implements DomainRuleInterface
{
    public function on()
    {
        return YourModel::CREATION;
    }
    
    public function execute(DomainEvent)
    {
        // Do Something on your model creation
    }
}

As your model needs a dispatcher you need to call the setDispatcher() method any time you create a new instance of your model. To avoid doing this manually you can use the Instantiator that the library provides.

It doesn't use the constructor to add the dispatcher because in PHP you can create objects without the constructor. For instance, that's what Doctrine does.

Use the bundle :

<?php
// In your Kernel class
public function registerBundles()
{
      return array(
          // ...
          new \Biig\Component\Domain\Integration\Symfony\DomainBundle(),
          // ...
      );
}
