Drupal 8 service dependency injection in our custom module

Drupal 8.7.x; Drupal 8.8.x; Drupal 8.9.x; Drupal 9.0.x; Drupal 9.1.x (active tab) Drupal 9.2.x; Introduction to services. A 'service' (such as accessing the database, sending email, or translating user interface text) can be defined by a module or Drupal core. Defining a service means giving it a name and designating a default class to provide.

  • Drupal is a free and open source content-management framework written in PHP and distributed under the GNU General Public License. Drupal provides a backend framework for at least 2.3% of all web sites worldwide – ranging from personal blogs to corporate, political, and government sites.
  • How to declare a custom service in your own Drupal 8 module. Using Dependency injection. Dependency injection is the concept of decoupled reusable functionality. This means we can write better and efficient code by reducing the execution time that’s why this is the preferred method and also because it is useful in writing Unit Tests.
Service

We are going to be learning Drupal 8 service dependency injection and we are going to be building on top of the module that we created in a previous video.

Dependency Injection enables us to decouple reusable functionality by injecting it, rather than creating it inside of a class (in our case service class).

Service

In order to find all the services that we have from Drupal 8 core - we could just search for a service on this page. There we will find the current user service. In order to inject it into our service we just have to take the service name and pass it as an argument in the .services.yml file like this:

and then in our service class we just have to get the service in the __construct method and store it in a local variable like this:

and then we could use the current user service and get the display name of the current logged in user in the whoIsYourOwner method.
