How to access host component from directive?

Question

Say I have the following markup:

Is there any way I can access the component instance

Answer 1

Your directive could be the generic one that can be applied to any of your components. So, in that case, injecting the component in constructor would not be possible, So here is one other way to do the same

Inject the ViewContainerRef in constructor

constructor(private _viewContainerRef: ViewContainerRef) { }

and then get it using

let hostComponent = this._viewContainerRef["_data"].componentView.component;
