Usage

usage.tsx
import {  QRCode,  QRCodeCanvas,  QRCodeSkeleton,} from "@/registry/bases/radix/ui/qr-code";export default function Example() {  return (    <QRCode      value="https://diceui.com"      size={150}      foregroundColor="#3b82f6"      backgroundColor="#f1f5f9"    >      <QRCodeCanvas />      <QRCodeSkeleton />    </QRCode>  );}
  • When demonstrating QR code color customization.
  • When showing high QR code error-correction settings.
  • When previewing QR code variants in a component gallery or documentation page.
  • When providing a responsive comparison of QR code configurations.

Examples

Custom brand colors

Use a branded foreground and background color for a QR code linking to a product page.

custom-brand-colors.tsx
import {  QRCode,  QRCodeCanvas,  QRCodeSkeleton,} from "@/registry/bases/radix/ui/qr-code";export default function BrandedQRCode() {  return (    <QRCode      value="https://example.com/product"      size={180}      foregroundColor="#7c3aed"      backgroundColor="#f5f3ff"    >      <QRCodeCanvas />      <QRCodeSkeleton />    </QRCode>  );}

High-reliability QR code

Use level H when the QR code may be partially obscured or printed in less predictable conditions.

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

Compact QR code

Render a smaller QR code for a compact settings or account panel.

compact-qr-code.tsx
import {  QRCode,  QRCodeCanvas,  QRCodeSkeleton,} from "@/registry/bases/radix/ui/qr-code";export default function CompactQRCode() {  return (    <QRCode value="https://example.com/account" size={120}>      <QRCodeCanvas />      <QRCodeSkeleton />    </QRCode>  );}

API reference

PropTypeDefaultDescription
valuestring—The content encoded by the QR code.
sizenumber—The rendered QR code size.
level"L" | "M" | "Q" | "H"—The QR code error-correction level. The demo uses "H" for high error correction.
foregroundColorstring—The QR code foreground color.
backgroundColorstring—The QR code background color.

Accessibility

  • The encoded URL is not exposed as readable text by the QR canvas itself; provide a visible text link or label for users who cannot scan the code.
  • Ensure sufficient contrast between foregroundColor and backgroundColor, especially for printed or low-light use.
  • Keep the QR code large enough to scan reliably on the target device or surface.
  • The QRCodeSkeleton is a loading fallback and should not be treated as the final accessible representation of the encoded content.
