How to use in plain HTML javascript?

Is it possible to use qrcode.js in a HTML page using <script> tag?

I tried this:

<script type="module" src="~/plugins/js-qrcode/qrcode.js"></script>

and also this:

<script type="module"> import { QRCodeCanvas } from '../plugins/js-qrcode/qrcode.js'; </script>

but always got JS errors...

Does not work in vue

QR not showing custom images

Hello, I've tested this library in a react app. I used the react logo as the logo of the QR and it works ok, but for example, if I modify this logo in Photoshop, let's say I add some text to it, and export as png, it will generate que QR with a blank image.
How can we solve this?
Also providing a URL to the source is not working.
Thanks!

Logo transparency

Hi,

first of all, great library!

I'm creating an SVG qr-code with a logo, and the logo has transparent background.
The transparency seems not to be kept when passing the image in the options of QRCodeSVG

options = {
      ...options,
      image: {
              source: path.resolve(__dirname, getLogoPath(buffer)), // Also tried  'data:image/png;base64,' + buffer.toString('base64'),
              width: 100/logoRatio + '%',
              height: 100/logoRatio + '%',
              x: 'center',
              y: 'center',
              border: 0
       }
}

const qrSVG = new QRCodeSVG(url, options)

the logo path is a local directory where the buffer is saved as PNG (e.g. /tmp/image.png).
I verified that the transparent background is preserved after the buffer is saved in the local directory.

Any help?

Thanks in advance

Thank you for making this library

This is the best QR code library I've found on the entire internet! It has exactly everything I need and works flawlessly.

Thank you for taking the time to build and open-source this.
