This contains the following modules.

Services Alias Example
An example of how to alias a service so that it can be called in using different names.

ddev exec php web/core/scripts/generate-proxy-class.php 'Drupal\\services_lazy_example\\SingleArgument' "web/modules/custom/drupal_services_examples/modules/services_lazy_example/src"NOTE: The module also needs to be installed for this command to work.

service.
Services Autoconfigured Service
An example of using the "autoconfigure: true" directive to automatically configure a service class.
