How to inject classes via container

How to get access to container?

I have a very simple search & replace method that needs settings.

    /**
    * @var SettingsRepositoryInterface
    */
    protected $settings;

    public function __construct(SettingsRepositoryInterface $settings)
    {
        $this->settings = $settings;
    }

How do I need to register thuis to be used in extend.php ?
I thought I could just use $this->app->make.. but that's not available on extend.php anymore.

    (new Extend\ApiSerializer(BasicPostSerializer::class))
    ->attributes(function($serializer, $model, $attributes) {
        $existing_content = $attributes['contentHtml'];
        $attributes['contentHtml']=$this->container->make(PostAffiliatorSerializer::class)->affiliate($existing_content);
        return $attributes;
    })

eddiewebb Like how do I do this, but not static...

   (new Extend\ApiSerializer(BasicPostSerializer::class))
    ->attributes([PostAffiliatorSerializer::class,'affiliate']),

It was in beta 16 update notes!

The remaining app and event global helper functions have been deprecated. app has been replaced with resolve, which takes the name of a container binding and resolves it through the container.

   (new Extend\ApiSerializer(BasicPostSerializer::class))
    ->attributes(function($serializer, $model, $attributes) {
        $existing_content = $attributes['contentHtml'];
        $attributes['contentHtml']= resolve(PostAffiliatorSerializer::class)->affiliate($existing_content);
        return $attributes;
    }),

Another "clean" way to inject composer dependencies in extenders is to use invokable classes as callbacks.

(new Extend\ApiSerializer(BasicPostSerializer::class))
    ->attributes(PostAttributes::class),

class PostAttributes
{
    protected $settings;

    public function __construct(SettingsRepositoryInterface $settings)
    {
        $this->settings = $settings;
    }

    public function __invoke($serializer, $model, $attributes)
    {
        // Your extender code
    }
}
