Angular 2 // Element autofocus

autofocus.ts

@Component({
  selector: 'my-comp',
  template: `
    <input #myInput type="text" />
    <div> Some other content </div>
  `
})
export class MyComp implements AfterViewInit {
  @ViewChild('myInput') input: ElementRef;

  constructor(private renderer: Renderer) {}

  ngAfterViewInit() {
    this.renderer.invokeElementMethod(this.input.nativeElement, 'focus');
  }
}

Works well. This works for me, avoiding the need for renderer:
this.input.nativeElement.focus()
