Как сгенерировать файл docx в браузере на клиенте?

const generate = () => { 
  const doc = new Document(); 
 
  const paragraph = new Paragraph("Hello World"); 
  const text1 = new TextRun("Foo Bar").bold(); 
  const text2 = new TextRun("Foo Bar").tab().bold(); 
   
  paragraph.addRun(text1); 
  paragraph.addRun(text2); 
  doc.addParagraph(paragraph); 
 
  const packer = new Packer(); 
 
  packer.toBlob(doc).then(blob => saveAs(blob, "example.docx")); 
} 
 
const button = document.querySelector('button'); 
button.addEventListener('click', generate);
