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

You could implement an Angular2 directive arount the clipboard.js library.

First configure the library into SystemJS:

We want to be able to attach clipboard on an element through a directive and provide as parameter the DOM element we want to link with. The value specified into the specified target element will be used to copy its text. Here is a sample of use:

  
  Copy

The implementation of the directive is the following:

import {Directive,ElementRef,Input,Output,EventEmitter} from 'angular2/core';
import Clipboard from 'clipboard';

@Directive({
  selector: '[clipboard]'
})
export class ClipboardDirective {
  clipboard: Clipboard;

  @Input('clipboard')
  elt:ElementRef;

  @Output()
  clipboardSuccess:EventEmitter = new EventEmitter();

  @Output()
  clipboardError:EventEmitter = new EventEmitter();

  constructor(private eltRef:ElementRef) {
  }

  ngOnInit() {
    this.clipboard = new Clipboard(this.eltRef.nativeElement, {
      target: () => {
        return this.elt;
      }
    });

    this.clipboard.on('success', (e) => {
      this.clipboardSuccess.emit();
    });

    this.clipboard.on('error', (e) => {
      this.clipboardError.emit();
    });
  }

  ngOnDestroy() {
    if (this.clipboard) {
      this.clipboard.destroy();
    }
  }
}
