How to use @HostBinding with @Input properties in Angular 2?

Question

(Angular 2 RC4)

With @HostBinding we should be able to modify properties of the host, right? My question is, does this apply to @Input() properties as well and if so

Answer 1

(1) declare hostbinding property with input property.

@HostBinding('attr.aaa') @Input() aaa: boolean = false;

(2) set hostbinding property to input property

@Input() aaa: string;
@HostBinding('attr.bbb') ccc: string;

ngOnInit(){
  this.ccc = this.aaa;
}
