--------------------------------

### useQrcode Composable Example

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/2.generate/2.use-qrcode.md

Demonstrates the basic usage of the useQrcode composable to generate a QR code. It takes a value and can optionally return a base64 encoded string.

```javascript
import { useQrcode } from '#imports';

const value = ref('https://example.com');
const toBase64 = ref(false);

const qrcode = useQrcode({
  value,
  toBase64
});
```

--------------------------------

### useQrcode Reactivity Example

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/2.generate/2.use-qrcode.md

Shows how the useQrcode composable automatically updates the QR code when its reactive properties (value, options) are changed.

```javascript
import { useQrcode } from '#imports';

const value = ref('initial value');

const qrcode = useQrcode({
  value
});

// Later, change the value
value.value = 'new value';
```

--------------------------------

### QR Code with Global Styling Applied

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/2.generate/1.qrcode.md

Renders a QR code using globally configured styles for `variant`, `radius`, `blackColor`, and `whiteColor`. This example shows a QR code with yellow and blue colors and a rounded variant.

```vue
<template>
  <Qrcode width="50%" value="https://nuxt.com" variant="rounded" :radius="1" />
</template>

<script setup>
// Assuming global config is set in nuxt.config.ts
// For demonstration, these props would be picked up from global options
// unless explicitly provided.
// props: {
//   width: '50%',
//   value: 'https://nuxt.com',
//   variant: 'rounded',
//   blackColor: 'yellow',
//   whiteColor: 'blue',
//   radius: 1
// }
</script>
```

--------------------------------

### Use Qrcode Component

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/README.md

Renders a QR code using the `Qrcode` component, requiring a 'value' prop and optionally accepting other customization props.

```vue
<template>
  <div>
    <Qrcode
      value="My string to encode"
      variant="pixelated"
    />
  </div>
</template>
```

--------------------------------

### Customize NuxtQRCode Defaults

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/README.md

Sets default options for QR code generation, such as variant style, radius, and pixel colors, within the `nuxt.config.ts` file.

```javascript
export default defineNuxtConfig({
  modules: ['nuxt-qrcode'],

  qrcode: {
    options: {
      variant: 'pixelated',
      // OR
      variant: {
        inner: 'circle',
        marker: 'rounded',
        pixel: 'rounded',
      },
      radius: 1,
      blackColor: 'currentColor', // 'var(--ui-text-highlighted)' if you are using `@nuxt/ui` v3
      whiteColor: 'transparent',  // 'var(--ui-bg)'
    },
  },
})
```

--------------------------------

### Use QrcodeStream Component

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/README.md

Implements live QR code detection using the `QrcodeStream` component, handling detected codes and potential errors via emitted events.

```vue
<template>
  <div>
    <QrcodeStream
      @error="onError"
      @detect="onDetect"
    />
  </div>
</template>

<script setup lang="ts">
import type { DetectedBarcode } from 'nuxt-qrcode'

function onDetect(detectedCodes: DetectedBarcode[]) {
  // do something with decoded qrcodes `DetectedBarcode['rawValue']`
}

function onError(err: Error) {
  // do something on stream error
}
</script>
```

--------------------------------

### Add NuxtQRCode to nuxt.config.ts

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/README.md

Configures the Nuxt.js application to use the NuxtQRCode module by adding it to the 'modules' array in `nuxt.config.ts`.

```javascript
export default defineNuxtConfig({
  modules: [
    'nuxt-qrcode'
  ]
})
```

--------------------------------

### Integrate NuxtQRCode with Nuxt UI

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/1.guide/2.configuration.md

Configure NuxtQRCode to automatically use colors defined in your Nuxt UI theme. Ensure 'nuxt-qrcode' is registered after '@nuxt/ui' or '@nuxt/ui-pro' in your nuxt.config.ts.

```typescript
export default defineNuxtConfig({
  modules: [
    '@nuxt/ui', // or `@nuxt/ui-pro`
    'nuxt-qrcode',
  ],
})
```

--------------------------------

### Configure NuxtQRCode Defaults

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/1.guide/2.configuration.md

Set default options for NuxtQRCode within the nuxt.config.ts file. This allows customization of QR code appearance, including variant style, radius, and pixel colors.

```typescript
export default defineNuxtConfig({
  modules: ['nuxt-qrcode'],

  qrcode: {
    options: {
      variant: 'pixelated',
      // OR
      variant: {
        inner: 'circle',
        marker: 'rounded',
        pixel: 'rounded',
      },
      radius: 1,
      blackColor: 'currentColor',
      whiteColor: 'transparent',
    },
  },
})
```

--------------------------------

### Basic Qrcode Generation

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/2.generate/1.qrcode.md

Generates a basic QR code using the `value` prop. The component accepts props like `width`, `white-color`, and `black-color` for customization.

```vue
<template>
  <Qrcode width="50%" value="https://qrcode.s94.dev" white-color="#FFF" black-color="#000" />
</template>

<script setup>
// Import Qrcode component if not globally available
// import Qrcode from 'nuxt-qrcode'
</script>
```

--------------------------------

### Global QR Code Styling Configuration

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/2.generate/1.qrcode.md

Configures global QR code options within `nuxt.config.ts` to set default `variant`, `radius`, `blackColor`, and `whiteColor`. This applies these styles across all QR code instances unless overridden.

```typescript
export default defineNuxtConfig({
  modules: ['nuxt-qrcode'],

  qrcode: {
    options: {
      variant: 'rounded',
      radius: 1,
      blackColor: 'yellow',
      whiteColor: 'blue',
    },
  },
})
```

--------------------------------

### QR Code Variants and Radius

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/2.generate/1.qrcode.md

Demonstrates different visual styles for QR codes using the `variant` prop, such as 'default', 'circle', 'pixelated', 'rounded', and 'dots'. The `radius` prop can be used to adjust corner roundness.

```vue
<template>
  <Qrcode width="50%" value="qrcode.s94.dev" variant="pixelated" :radius="1" />
</template>

<script setup>
// Example with object for selective customization
// :variant="{
//   inner: 'circle',
//   marker: 'rounded',
//   pixel: 'dots'
// }"
</script>
```

--------------------------------

### Disable Nuxt UI Integration for NuxtQRCode

Source: https://github.com/sandros94/nuxt-qrcode/blob/main/docs/content/1.guide/2.configuration.md

Revert the automatic integration of Nuxt UI colors for QR codes by setting 'disableNuxtUiIntegration' to true in the NuxtQRCode configuration.

```typescript
export default defineNuxtConfig({
  // ...

  qrcode: {
    options: {
      disableNuxtUiIntegration: true,
    },
  },
})
```
