How do I copy to clipboard in Angular 2 Typescript?

Question

Is there a way to copy text in clipboard (multi-browser) in Angular2 Typescript framework?

I find only sources of using Javascript, e.g.

document.exe

Here is a way to achieve this without any external dependency or creating fake elements, only by using Clipboard API:

import { DOCUMENT } from '@angular/common';
import { Directive, EventEmitter, HostListener, Inject, Input, Output } from '@angular/core';

@Directive({
  selector: '[myClipboard]'
})
export class ClipboardDirective {

  @Input() myClipboard: string;
  @Output() myClipboardSuccess = new EventEmitter();

  constructor(@Inject(DOCUMENT) private document: Document) {}

  @HostListener('click')
  onClick() {
    this.document.addEventListener('copy', this.handler);
    this.document.execCommand('copy');
  }

  private handler = (e: ClipboardEvent) => {
    e.clipboardData.setData('text/plain', this.myClipboard);
    e.preventDefault();
    this.myClipboardSuccess.emit(e);
    this.document.removeEventListener('copy', this.handler);
  }

}
