Module Development

Concept: Creating Custom Services for Drupal 8, 9, 10, and 11

Custom services in Drupal modules encapsulate specific business logic or functionality. In our example, we'll demonstrate moving code required to access a weather forecast API from a controller into a service. This will help make our controller thin and our module code more reusable, testable, and maintainable.

In this tutorial, we'll:

  • Explore the advantages of custom services for managing business logic.
  • Define the components of a custom service.

By the end of this tutorial, you'll understand why creating custom services is a beneficial practice in Drupal module development.
