Download the PHP package dotkernel/dot-annotated-services without Composer

dot-annotated-services

Dotkernel component used to create services through Laminas Service Manager and inject them with dependencies just using method annotations. It can also create services without the need to write factories. Annotation parsing can be cached, to improve performance.

This package can clean up your code, by getting rid of all the factories you write, sometimes just to inject a dependency or two.

Installation

Run the following command in your project directory

After installing, add the ConfigProvider class to your configuration aggregate.

Usage

Using the AnnotatedServiceFactory

You can register services in the service manager using the AnnotatedServiceFactory as below.

You can use only the fully qualified class name as the service key.

The next step is to annotate the service constructor or setters with the service names to inject.

The annotation @Inject is telling the factory to inject the services between curly braces. Valid service names should be provided, as registered in the service manager.

To inject an array value from the service manager, you can use dot notation as below,

which will inject $container->get('config')['debug'];

Even if using dot annotation, the annotated factory will check first if a service name exists with that name.

You can use the inject annotation on setters too, they will be called at creation time and injected with the configured dependencies.

Using the AnnotatedRepositoryFactory

You can register doctrine repositories and inject them using the AnnotatedRepositoryFactory as below.

The next step is to add the @Entity annotation in the repository class.

The name field has to be the fully qualified class name.

Every repository should extend Doctrine\ORM\EntityRepository.

Using the abstract factory

Using this approach, no service manager configuration is required. It uses the registered abstract factory to create annotated services.

In order to tell the abstract factory which services are to be created, you need to annotate the service class with the @Service annotation.

And that's it, you don't need to configure the service manager with this class, creation will happen automatically.

Cache annotations

This package is built on top of doctrine/annotation and doctrine/cache. In order to cache annotations, you should register a service factory at key AbstractAnnotatedFactory::CACHE_SERVICE that should return a valid Doctrine\Common\Cache\Cache cache driver. See Cache Drivers for available implementations offered by doctrine.

Below, we give an example, as defined in our frontend and admin starter applications:
