تجربتي الجديدة مع dom-to-image (لا تعمل مع الآيفون):

import domToImage from 'dom-to-image';

var domtoimage = require('dom-to-image');

  onDownload() {
    const element = document.querySelector('#screen');
    domToImage.toPng(element).then((dataUrl:any) => {
      const link = document.createElement('a');
      link.href = dataUrl;    
      link.download = 'greeting-card.png';
      link.click();
    });
