Go deeply into Symfony Provide *all* the services that are available within the Drupal core Solve *all* your Drupal 8 problems Talk about REST (in Drupal 7, Services’ meaning is different)

Important note! Why do I say this talk is targeted to beginners?

Target: Drupal < 8 developers

The learning curve for most of the developers we’ve been working on previous Drupal versions before can be hard, mostly because the CMS had a hook-based approach, and now is moving to an Object-Oriented Paradigm.

SLIDE 10

Target: Drupal freshmen.

If you’re brand new on Drupal, finding out there’s so many things to learn could be the first blocker, whether if you’re a content manager, a designer, a front-end or back-end developer.

What’s a Drupal 8 Service?

Let’s throw the mystery away, a Service is a PHP Class (or a bunch of classes, depending on your implementation).

  • Decoupled reusable functionality
  • Plugged to your Drupal 8 at any time
  • Introduced in Drupal by Symfony.

Accessing a Service: $container object

// EntityViewBuilder.php public static function createInstance(ContainerInterface $container, EntityTypeInterface $entity_type) { return new static( $entity_type, $container->get('entity.manager'), $container->get('language_manager'), $container->get('theme.registry') ); }
