Simple function that transforms HTML to PDF.

toPDF.ts

import html2canvas from "html2canvas";
import jsPDF from "jspdf";  

const exportPDF = () => {
    const input = document.getElementById("documentID") as HTMLElement;
    html2canvas(input, { logging: true, useCORS: true }).then((canvas) => {
      const imgWidth = 290;
      const imgHeight = 210;
      const imgData = canvas.toDataURL("img/png"); transform canvas to an image
      const pdf = new jsPDF("l", "mm", "a4"); // L is landscape, you can use whatever you want for example p to make it portrait
      pdf.addImage(imgData, "PNG", 5, 5, imgWidth, imgHeight);
      pdf.save(`documentName`); //The name of the document
    });
  };
