A QR code web component, drop it in anywhere.
This uses Lit, so first add Lit to your importmap.
Then you can just use it anywhere:
<script type="module">
import 'https://cdn.jsdelivr.net/gh/treeder/qr-code@0/qr-code.js'
</script>
<qr-code value="SOME VALUE"></qr-code>
These can be passed in as HTML attributes, eg:
<qr-code size="200" value="SOME VALUE"></qr-code>- size - sets height and width of the QR image - default: 128
