  • Show a URL or other scannable value in a settings, sharing, or account flow.

  • Use as a minimal integration example for the QR code registry component.
  • Display a temporary loading state before the QR code canvas is ready.

Examples

Website QR code

Render a QR code that points to a product website.

website-qr-code.tsx
import { QRCode, QRCodeCanvas, QRCodeSkeleton } from "@/registry/bases/radix/ui/qr-code";export function WebsiteQRCode() {  return (    <QRCode value="https://example.com" size={200}>      <QRCodeSkeleton />      <QRCodeCanvas />    </QRCode>  );}

Account sharing QR code

Render a QR code for an account-specific sharing URL.

account-sharing-qr-code.tsx
import { QRCode, QRCodeCanvas, QRCodeSkeleton } from "@/registry/bases/radix/ui/qr-code";export function AccountShareQRCode({ token }: { token: string }) {  return (    <QRCode value={`https://example.com/share/${token}`} size={240}>      <QRCodeSkeleton />      <QRCodeCanvas />    </QRCode>  );}

Mobile handoff QR code

Use the component in a card-sized mobile handoff surface.

mobile-handoff-qr-code.tsx
import { QRCode, QRCodeCanvas, QRCodeSkeleton } from "@/registry/bases/radix/ui/qr-code";export function MobileHandoffQRCode() {  return (    <div>      <p>Scan to continue on your phone</p>      <QRCode value="https://example.com/continue" size={160}>        <QRCodeSkeleton />        <QRCodeCanvas />      </QRCode>    </div>  );}

Accessibility

  • The demo does not provide an accessible name or text alternative for the encoded destination.
  • Provide visible text or an adjacent link that identifies the encoded URL or action for people who cannot scan the QR code.
  • Ensure sufficient contrast between the QR code modules and its background, and preserve a clear quiet zone around the code.
  • Do not rely on the QR code as the only way to complete an action; provide an equivalent accessible link or destination.
