Dependency Injection 3.0.0 ​

SailCMS supports Dependency Injection on classes used in GraphQL and Routes. If you don't know what DI is, please visit Wikipedia on the subject.

The only thing important to understand, any dependency must allow to be instantiated without any arguments. Here is an example of DI.

class YourController extends AppController
{
    private DependencyType $yourDep;
    
    public function __construct(protected DependencyType $yourDep) {}
}

You might be asking what is the point of this, this helps you not have to write repetitive code to initialize your dependencies on every method as it will be done for you.

To enjoy the benefits of DI, you must have a constructor on your class (controller or other). You do not need to do anything special to profit from DI, it will be detected automatically.
