qr-code

QRCode generates an SVG QR code from a string and renders it inside a full-size `<div>`. The client version derives colors from the document theme by default, while the server version requires explicit foreground and background colors.

Installation

pnpm dlx shadcn@latest add @kibo-ui/qr-code

Requires @kibo-ui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { QRCode } from "@/components/kibo-ui/qr-code";<QRCode data="https://example.com/invite/abc123" className="size-48" />
  • Display URLs, invite links, payment references, or other scannable text.
  • Use in responsive cards, dialogs, checkout flows, or sharing panels where the QR code should fill its parent.
  • Use the client version when QR colors should follow the application’s `--foreground` and `--background` theme variables.
  • Use the server version for server-rendered output with explicit, deterministic colors.

Examples

Themed invite QR code

Uses the client component’s theme-derived colors and fills a fixed square.

themed-invite-qr-code.tsx
import { QRCode } from "@/components/kibo-ui/qr-code";<QRCode  data="https://example.com/invite/abc123"  className="size-48"  aria-label="QR code for joining the team"/>

Custom-colored QR code

Supplies explicit colors and high error correction for a printed or partially obstructed code.

custom-colored-qr-code.tsx
import { QRCode } from "@/components/kibo-ui/qr-code";<QRCode  data="mailto:hello@example.com"  foreground="#111827"  background="#ffffff"  robustness="H"  className="size-64"  aria-label="QR code for emailing support"/>

Server-rendered QR code

Uses the server variant with required explicit colors.

server-rendered-qr-code.tsx
import { QRCode } from "@/components/kibo-ui/qr-code/server";export default async function SharePage() {  return (    <QRCode      data="https://example.com/share/7f3c"      foreground="#111827"      background="#ffffff"      className="size-56"      aria-label="QR code for sharing this page"    />  );}

QR code with surrounding layout

The component can be placed in a styled parent while its SVG expands to the parent size.

qr-code-with-surrounding-layout.tsx
import { QRCode } from "@/components/kibo-ui/qr-code";<div className="size-52 rounded-xl bg-white p-4">  <QRCode    data="WIFI:T:WPA;S:Guest Network;P:welcome123;;"    foreground="#000000"    background="#ffffff"    className="size-full"    aria-label="QR code for the guest Wi-Fi network"  /></div>

API reference

PropTypeDefaultDescription
datastringnullThe string encoded into the QR code.
foregroundstringClient: undefined; server: requiredThe QR code’s dark color. The client version falls back to the document `--foreground` CSS variable, and the server version requires this prop.
backgroundstringClient: undefined; server: requiredThe QR code’s light color. The client version falls back to the document `--background` CSS variable, and the server version requires this prop.
robustness"L" | "M" | "Q" | "H""M"QR error-correction level: `L`, `M`, `Q`, or `H`.
classNamestringnullOptional class names merged with the component’s `size-full` and `[&_svg]:size-full` classes.
...propsReact.HTMLAttributes<HTMLDivElement>nullAll other standard HTML attributes for the root `<div>`, including `id`, event handlers, `aria-*` attributes, and `data-*` attributes.

Accessibility

  • The component does not add an accessible name automatically; provide an `aria-label` on the component when the QR code conveys meaningful information.
  • The root element accepts standard HTML attributes, so `role="img"` can be added when appropriate.
  • If the QR code duplicates a nearby text link or action, consider `aria-hidden="true"` and expose the textual destination separately.
  • Ensure sufficient contrast between foreground and background colors and keep the QR code large enough to scan.
  • The client version renders nothing until asynchronous QR generation completes, so avoid relying on it as the only content for a critical interaction.
