You get the host element reference using

class MyComponent {
constructor(private elRef:ElementRef) {
console.log(this.elRef.nativeElement);
}
}

You can also subscribe to the focus event

class MyComponent {
@HostBinding() tabindex = 0;
@HostListener('focus', ['$event'])
onFocus(event) {
console.log(event);
}
}

Use ViewContainerRef that represents a container where one or more views can be attached to a component.

constructor(private readonly viewRef: ViewContainerRef) {


console.log(this.viewRef.element.nativeElement);
}
