ViewContainerRef

Class

Represents a container where one or more views can be attached to a component.

  
    abstract class ViewContainerRef {
}

Represents a container where one or more views can be attached to a component.

Can contain host views (created by instantiating a component with the createComponent() method), and embedded views (created by instantiating a TemplateRef with the createEmbeddedView() method).

A view container instance can contain other view containers, creating a view hierarchy.

The example below demonstrates how the createComponent function can be used to create an instance of a ComponentRef dynamically and attach it to an ApplicationRef, so that it gets included into change detection cycles.

Note: the example uses standalone components, but the function can also be used for non-standalone components (declared in an NgModule) as well.

          @Component({  standalone: true,  selector: 'dynamic',  template: `<span>This is a content of a dynamic component.</span>`,})class DynamicComponent {  vcr = inject(ViewContainerRef);}@Component({  standalone: true,  selector: 'app',  template: `<main>Hi! This is the main content.</main>`,})class AppComponent {  vcr = inject(ViewContainerRef);  ngAfterViewInit() {    const compRef = this.vcr.createComponent(DynamicComponent);    compRef.changeDetectorRef.detectChanges();  }}

element

ElementRef<any>

Anchor element that specifies the location of this container in the containing view. Each view container can have only one anchor element, and each anchor element can have only a single view container.

Root elements of views attached to this container become siblings of the anchor element in the rendered view.

Access the ViewContainerRef of an element by placing a Directive injected with ViewContainerRef on the element, or use a ViewChild query.

createComponent

2 overloads

Instantiates a single component and inserts its host view into this container.

@paramcomponentTypeType<C>

Component Type to use.

@paramoptions

{ index?: number; injector?: Injector; ngModuleRef?: NgModuleRef<unknown>; environmentInjector?: EnvironmentInjector | NgModuleRef<unknown>; projectableNodes?: Node[][]; }

An object that contains extra parameters:

index: the index at which to insert the new component's host view into this container. If not specified, appends the new view as the last entry.
injector: the injector to use as the parent for the new component.
ngModuleRef: an NgModuleRef of the component's NgModule, you should almost always provide this to ensure that all expected providers are available for the component instantiation.
environmentInjector: an EnvironmentInjector which will provide the component's environment. you should almost always provide this to ensure that all expected providers are available for the component instantiation. This option is intended to replace the ngModuleRef parameter.
projectableNodes: list of DOM nodes that should be projected through <ng-content> of the new component instance.

@returnsComponentRef<C>

Instantiates a single component and inserts its host view into this container.

@deprecated

Angular no longer requires component factories to dynamically create components. Use different signature of the createComponent method, which allows passing Component class directly.
