Dependency injection#

All services are bundled in a service container. This container is built during bootstrapping. It depends on the following resources:

  • Default service configuration, located at config of this package

  • Project type specific service configuration, located at config within an external template repository

Tagged services#

Some special services exist that are tagged during container build-time:

Tag name

Resource

builder.writer

Builder\Writer\WriterInterface

event.listener

–

expression_language.provider

Symfony\Component\ExpressionLanguage\ExpressionFunctionProviderInterface

generator.step

Builder\Generator\Step\StepInterface

io.validator

IO\Validator\ValidatorInterface

twig.filter

Twig\Filter\TwigFilterInterface

twig.function

Twig\Func\TwigFunctionInterface

Synthetic services#

The following services are configured to be synthetic. They are added to the compiled container during bootstrapping.

Service id

Class name

app.config

Builder\Config\Config

app.messenger

IO\Messenger

Extending service configuration#

Service configuration can be extended by each project type. Once a user selects a project type during bootstrapping, the project type’s template directory is being searched for the following resources:

  • config/services.php

  • config/services.yaml

  • config/services.yml

Tip

You can define more than one service configuration per project type.
