We can use @ViewChild with component:

@ViewChild(AuthMessageComponent) message: AuthMessageComponent;//.... ngAfterContentInit() {    if (this.message) {      this.message.days = 30;    }  }

By doing this, we actually can access component's prop and events.

 

If we want to get component DOM node, what we can do is using template ref.

@ViewChild('email') email: ElementRef;// ....  ngAfterViewInit() {    console.log(this.email); // ElementRef  }
