html2canvas VS asdom

GItHub :- https://github.com/niklasvh/html2canvas

That's slightly harder, but still possible by first rendering the HTML onto a canvas.

Example here: http://html2canvas.hertzen.com/

If you have it working in the browser you could use this.https://html2canvas.hertzen.com/

, etc. for styling. So we need to parse our DOM as canvas and then convert it into a png. There's a libary which helps us do just that. html2canvas. We modify our downloadQRCode function such that first we get snapshot of our DOM as a canvas then we convert that into a png. Final code // QRCodeTemplate.tsx import React from "react" import html2canvas from "html2canvas" import { QRCodeCanvas } from "qrcode.react" import Button from "components/Button" import QRCodeTemplate from "components/dashboard/QRCodeTemplate" const QRCodeDownload = () => { const url = "https://anshsaini.com" const getCanvas = () => { const qr = document.getElementById("fancy-qr-code") if (!qr) return return html2canvas(qr, { onclone: snapshot => { const qrElement = snapshot.getElementById("fancy-qr-code") if (!qrElement) return // Make element visible for cloning qrElement.style.display = "block" }, }) } const downloadQRCode = async () => { const canvas = await getCanvas() if (!canvas) throw new Error(" not found in DOM") const pngUrl = canvas .toDataURL("image/png") .replace("image/png", "image/octet-stream") const downloadLink = document.createElement("a") downloadLink.href = pngUrl downloadLink.download = "QR code.png" document.body.appendChild(downloadLink) downloadLink.click() document.body.removeChild(downloadLink) } return (

QRCodeTemplate>

Download QR CodeButton> div> div> ) } export default QRCodeDownload Enter fullscreen mode Exit fullscreen mode The Result We have a beautiful QR code saved as a png. And with the power of React, we can create as many styles as we want.

Hey guys, I using html2canvas in our project and I am facing this issue.

use http://html2canvas.hertzen.com/ to convert the div to an image if you want

This looks super useful! I’ve previously used [html2canvas](https://html2canvas.hertzen.com/) to make a simple tool for generating graphics for a news org, but I can see myself using this going forward.

Speaking of WebAssembly, just wait! JSX is coming to AssemblyScript (TypeScript to WebAssembly compiler). There are already DOM bindings in place (https://github.com/lume/asdom, not complete, but has reasonable APIs bound already, and more coming). With JSX in place we'll be able to make something like Solidjs all in WebAssembly but in the same familiar syntax we already know, and not slow like Blazor.
