NgModuleRef

class

Represents an instance of an NgModule created by an NgModuleFactory. Provides access to the NgModule instance and related objects.

abstract class NgModuleRef<T> {
  abstract injector: EnvironmentInjector
  abstract componentFactoryResolver: ComponentFactoryResolver
  abstract instance: T
  abstract destroy(): void
  abstract onDestroy(callback: () => void): void
}

Properties

Property Description
abstract injector: EnvironmentInjector Read-Only

The injector that contains all of the providers of the NgModule.
abstract componentFactoryResolver: ComponentFactoryResolver Deprecated Read-Only

Note: since v13, dynamic component creation via ViewContainerRef.createComponent does not require resolving component factory: component class can be used directly.

Deprecated Angular no longer requires Component factories. Please use other APIs where Component class can be used directly.
