# QRCode
Used to quickly access scannable data.
### Basic QR Code

```tsx
import {
  reactExtension,
  Link,
  QRCode,
  TextBlock,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return (
    <>
      <QRCode content="https://shopify.com" />

      <TextBlock>
        Scan to visit{' '}
        <Link to="https://shopify.com">
          Shopify.com
        </Link>
      </TextBlock>
    </>
  );
}

```

```js
import {
  extension,
  Link,
  QRCode,
  TextBlock,
} from '@shopify/ui-extensions/checkout';

export default extension('purchase.checkout.block.render', (root) => {
  const qrCode = root.createComponent(QRCode, {
    content: 'https://shopify.com',
  });

  const textBlock = root.createComponent(TextBlock, null, [
    'Scan to visit ',
    root.createComponent(Link, {to: 'https://shopify.com'}, 'Shopify.com'),
  ]);

  root.appendChild(qrCode);
  root.appendChild(textBlock);
});

```


## QRCodeProps

### QRCodeProps

### accessibilityLabel
A label that describes the purpose or contents of the QR code. When set, it will be announced to users using assistive technologies and will provide more context about what the QR code may do when scanned.
### border
Adjust the border style.
### content
The content to be encoded in the QR code, which can be any string such as a URL, email address, plain text, etc. Specific string formatting can trigger actions on the user’s device when scanned, like opening geolocation coordinates on a map, opening a preferred app or app store entry, preparing an email, text message, and more.
### id
A unique identifier for the component.
### logo
URL of an image to be displayed in the center of the QR code. This is useful for branding or to indicate to the user what scanning the QR code will do. By default, no image is displayed.
### onError
Invoked when the conversion of `content` to a QR code fails. If an error occurs, the QR code and its child elements will not be displayed.
### size
The displayed size of the QR code.

`fill`: the QR code will takes up 100% of the available inline-size and maintain a 1:1 aspect ratio.

`auto`: the QR code will be displayed at its default size.
### BorderStyle

'base' | 'dashed' | 'dotted' | 'none'

## Examples

### 
The QRCode component can display an image in the center. Adding a logo can increase brand trust and set expectations for the action when scanning.
### With logo

```jsx
import {
  reactExtension,
  Link,
  QRCode,
  TextBlock,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return (
    <>
      <QRCode
        content="https://shopify.com"
        logo="https://cdn.shopify.com/YOUR_IMAGE_HERE"
      />

      <TextBlock>
        Scan to visit{' '}
        <Link to="https://shopify.com">
          Shopify.com
        </Link>
      </TextBlock>
    </>
  );
}

```

```js
import {
  extension,
  QRCode,
  TextBlock,
  Link,
} from '@shopify/ui-extensions/checkout';

export default extension(
  'purchase.checkout.block.render',
  (root) => {
    const qrCode = root.createComponent(QRCode, {
      content: 'https://shopify.com',
      logo: 'https://cdn.shopify.com/YOUR_IMAGE_HERE',
    });

    const textBlock = root.createComponent(
      TextBlock,
      null,
      [
        'Scan to visit ',
        root.createComponent(
          Link,
          {to: 'https://shopify.com'},
          'Shopify.com',
        ),
      ],
    );

    root.appendChild(qrCode);
    root.appendChild(textBlock);
  },
);

```


### 
In most cases the default size should work well. If you need a different size, use `fill` to make it grow to the size of its parent container.
### Fill size

```jsx
import {
  reactExtension,
  QRCode,
  View,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  return (
    <View maxInlineSize={300}>
      <QRCode
        content="https://shopify.com"
        size="fill"
      />
    </View>
  );
}

```

```js
import {
  extension,
  View,
  QRCode,
} from '@shopify/ui-extensions/checkout';

export default extension(
  'purchase.checkout.block.render',
  (root) => {
    const view = root.createComponent(View, {
      maxInlineSize: 300,
    });

    const qrCode = root.createComponent(QRCode, {
      content: 'https://shopify.com',
      size: 'fill',
    });

    view.appendChild(qrCode);
    root.appendChild(view);
  },
);

```


### 
When displaying a QR code, include an alternative way for the user to get the content
### Copying content of a QR code to the user's clipboard

```jsx
import {
  reactExtension,
  BlockStack,
  Button,
  ClipboardItem,
  QRCode,
} from '@shopify/ui-extensions-react/checkout';

export default reactExtension(
  'purchase.checkout.block.render',
  () => <Extension />,
);

function Extension() {
  const bitcoinAddress =
    '14qViLJfdGaP4EeHnDyJbEGQysnCpwk3gd';

  return (
    <BlockStack maxInlineSize={200}>
      <QRCode
        size="fill"
        content={`bitcoin:${bitcoinAddress}`}
      />
      <Button activateTarget="bitcoin-address">
        Copy Bitcoin address
      </Button>
      <ClipboardItem
        text={bitcoinAddress}
        id="bitcoin-address"
      />
    </BlockStack>
  );
}

```

```js
import {
  extension,
  BlockStack,
  Button,
  ClipboardItem,
  QRCode,
} from '@shopify/ui-extensions/checkout';

export default extension(
  'purchase.checkout.block.render',
  (root) => {
    const bitcoinAddress =
      '14qViLJfdGaP4EeHnDyJbEGQysnCpwk3gd';
    const qrCodeContent = `bitcoin:${bitcoinAddress}`;

    const qrCode = root.createComponent(QRCode, {
      content: qrCodeContent,
      size: 'fill',
    });

    const clipboardItem = root.createComponent(
      ClipboardItem,
      {
        text: bitcoinAddress,
        id: 'bitcoin-address',
      },
    );

    const button = root.createComponent(
      Button,
      {
        activateTarget: 'bitcoin-address',
      },
      'Copy Bitcoin address',
    );

    const blockStack = root.createComponent(
      BlockStack,
      {
        maxInlineSize: 200,
      },
    );

    blockStack.appendChild(qrCode);
    blockStack.appendChild(button);
    blockStack.appendChild(clipboardItem);

    root.appendChild(blockStack);
  },
);
