How to configure a service

In the previous topic, we got the mava_util service and used its methods to fetch user projects and tasks with various statuses. How does a service container construct a service? In other words, where are the configurations defined?

As developers, we give instructions on how to construct and return a service via the config.yml file. We can put the instructions directly in the config.yml file or somewhere else (that is, services.yml) and import them to config.yml.

Keep in mind that if you defined your services in a bundle, no further configuration is required and they will be loaded automatically. We will read more about this soon.

Open the mava/src/AppBundle/resources/config/services.yml file and note the definition for mava_util:

services:
   # ...
   mava_util:
      class: AppBundle\Util\Mava
      arguments: ['@doctrine.orm.entity_manager']

In this configuration, the class entry defines where the body of a service is located and arguments are a list of parameters...
