How to export/save result?

[datvm]

Sorry maybe I am missing something but there is no documentation on any method to get the result to save to storage, like Canvas/SVG/PNG. Is this supported?

I don't know of an "official" way, but I've found a hacky way:

const base64doc = btoa(unescape(encodeURIComponent(document.getElementById('qr1').shadowRoot.querySelector('svg').outerHTML)));
const a = document.createElement('a');
const e = new MouseEvent('click');

a.download = 'download.svg';
a.href = 'data:text/html;base64,' + base64doc;
a.dispatchEvent(e);

Effectively, grab the qr-code instance, jump into its shadow root to then find the SVG that is rendering the image. From there, it's really up to you how you want to trigger a download of a file. I've included one such way. Not sure if it's the best way, but it's a way that works 😅
