An expected QRCode would be something like:

frame (2)

When I shorten the text it is working again:

https://xx.xxxxxx.xxxxx/access?v=1#xxxxxx Ladebox AABBCC;xxxxxx-aabbcc;0000-1111-2222-3333;BAPchN1DqT+qCQj0e2YI9hcucAPTHfo8dIghaU+9FKYuK3DPCeSrXL1Xiw7mVnQgZYEtQyJ65OmE5xd84Z/TCtk=|xxxxxx-aabbcc;1234|xxxxxx Ladebox AABBCC;WLANAPPASSWORD|MHcCAQEEIOT8am0Gm12s8FrYyey9ZGxokJYFq9SwnZXrKMapk2AioAoGCCqGSM49AwEHoUQDQgAEA9yE3UOpP6oJCPR7Zgj2Fy5wA9Md+jx0iCFpT70Upi4rcM8J5KtcvVeLDuZWdCBlgS1DInrk6YTnF3zhn9MK2Q==;|

The longest working text seems to be 425 characters. So when it is expected to switch from QRCode version 13 to 14.

svg data

Is it possible to only get the data from the svg?

Feature request: position & css var's for fill color

It would be great, if we could do something like this:

QRCode({
    msg: 'xxxxxxxxxxxxx',
    dim: 120,
    pal: ['var(--primary-color)', 'var(--secondary-color)'],
    x: 123,
    y: 45
})

that will result in:

<svg x="123" y="45" viewBox="0 0 37 37" width="120" height="120" fill="var(--primary-color)" ...

Suggestions

Great library!

  1. Would be neat with non-minified code, so one could inspect + suggest improvements.
  2. Have you considered publishing as ES6 module to NPM? So one can include it via NPM, and run in node or run in the browser (many browser apps are build with NPM packages).
