Qr code

QR Code

A component that generates a QR code based on the provided data.

Anatomy

To set up the QR code correctly, you'll need to understand its anatomy and how we name its parts.

Each part includes a data-part attribute to help identify them in the DOM.

Examples

Learn how to use the QR Code component in your project. Let's take a look at the most basic example:

import { QrCode } from '@ark-ui/react'

export const Basic = () => {
  return (
    <QrCode.Root value="http://ark-ui.com">
      <QrCode.Frame>
        <QrCode.Pattern />
      </QrCode.Frame>
    </QrCode.Root>
  )
}

With Overlay

You can also add a logo or overlay to the QR code. This is useful when you want to brand the QR code.

import { QrCode } from '@ark-ui/react'

export const Basic = () => {
  return (
    <QrCode.Root value="http://ark-ui.com" encoding={{ ecc: 'H' }}>
      <QrCode.Frame>
        <QrCode.Pattern />
      </QrCode.Frame>
      <QrCode.Overlay>
        <img src="https://ark-ui.com/icon-192.png" alt="Ark UI Logo" />
      </QrCode.Overlay>
    </QrCode.Root>
  )
}

Error Correction

In cases where the link is too long or the logo overlay covers a significant area, the error correction level can be increased.

Use the encoding.ecc or encoding.boostEcc property to set the error correction level:

  • L: Allows recovery of up to 7% data loss (default)
  • M: Allows recovery of up to 15% data loss
  • Q: Allows recovery of up to 25% data loss
  • H: Allows recovery of up to 30% data loss
import { QrCode } from '@ark-ui/react'

export const Basic = () => {
  return (
    <QrCode.Root value="http://ark-ui.com" encoding={{ ecc: 'H' }}>
      <QrCode.Frame>
        <QrCode.Pattern />
      </QrCode.Frame>
    </QrCode.Root>
  )
}
