Question 1

How do I animate a QR code when a user clicks on it?

Accepted Answer

Attach an event listener to the element and call the animateQRCode method with a preset name, like in the example using 'RadialRipple'. For custom interactions, you can trigger animations based on user events.

Question 2

qr-code component vs qrcode.js: which is better?

Accepted Answer

uses SVG for crisp, scalable rendering and has built-in animations, while qrcode.js typically outputs canvas or images with fewer styling options. Choose for rich visuals and Web Component integration, but qrcode.js might be simpler for basic, non-animated codes.

Question 3

Can I use qr-code with React without issues?

Accepted Answer

Yes, but you'll need to import it as a custom element and handle it in JSX; state updates might not be reactive by default, so manual DOM manipulation could be required for dynamic changes.

Question 4

How to change the size of the QR code dynamically?

Accepted Answer

Use CSS styles like 'width' and 'height' on the element, as shown in the full example with inline styles. The SVG scales accordingly, but ensure the contents attribute is set correctly for the desired data.

Question 5

Is the qr-code component accessible for screen readers?

Accepted Answer

The README doesn't mention accessibility features; you may need to add ARIA attributes manually, such as aria-label for the QR code content, to ensure compatibility with assistive technologies.

Question 6

What browsers support the qr-code Web Component?

Accepted Answer

It works in modern browsers that support Web Components (custom elements and Shadow DOM), but older browsers like Internet Explorer require polyfills, which aren't covered in the documentation.
