How does Angular handle structural directives internally?

Mid Angular
Quick Answer Structural directives use embedded views internally. When you write *ngIf="show", Angular desugars it to: . The directive receives a TemplateRef and ViewContainerRef via DI. It calls viewContainerRef.createEmbeddedView(templateRef) to show and viewContainerRef.clear() to hide. The asterisk is pure syntactic sugar for the ng-template pattern.

Answer

Transforms structural directives into template instructions manipulating embedded views.
