// 1. External packages (react, etc.) — only if needed for examples
import {useState} from 'react';

// 2. @sentry/scraps component(s)
import {ComponentName} from '@sentry/scraps/<component>';

// 3. Sentry internals used in examples (icons, utils)
import {IconAdd} from '@sentry/icons/add';
import {IconEdit} from '@sentry/icons/edit';
// 4. Stories namespace (always last before type-loader)
import * as Storybook from 'sentry/stories';

// 5. Type-loader for auto-generated API docs (@sentry/scraps components only)
import documentation from '!!type-loader!@sentry/scraps/<component>';

export {documentation};

import RawDocumentation from '!!type-loader!@sentry/scraps/<component>';

export const documentation = {
  exports: RawDocumentation.exports,
  props: {
    ...RawDocumentation?.props,
    // Remove internal props if needed
  },
};

## When to use

Use `<Alert>` for inline feedback within a page. For application-level banners that span the full viewport, use the `system` prop or reach for `<Toast>` if the message is transient.

> [!WARNING]
> Do not use `<Alert variant="danger">` for confirmation dialogs. Use a modal instead.

## See Also

- [LinkButton](/stories/core/linkbutton/) — use when the action navigates to a new URL
- [Link](/stories/core/link/) — use for inline text navigation, not standalone CTAs

To create a basic <component>, wrap content in `<ComponentName>`.

```jsx
<ComponentName prop="value">Content</ComponentName>
```

### Sub-components

When a component exposes sub-components, show the full compound usage early:

```mdx
`<Tabs>` is a compound component. Use `<TabList>` and `<TabPanels>` together:

```jsx
<Tabs>
  <TabList>
    <TabList.Item key="tab1">Tab 1</TabList.Item>
  </TabList>
  <TabPanels>
    <TabPanels.Item key="tab1">Content 1</TabPanels.Item>
  </TabPanels>
</Tabs>

### Demo pattern

Every feature section must have a `<Storybook.Demo>` followed **immediately** by the matching code block:

```mdx
## Sizes

<brief description>

<Storybook.Demo>
  <Component size="sm">Small</Component>
  <Component size="md">Medium</Component>
  <Component size="lg">Large</Component>
</Storybook.Demo>
```jsx
<Component size="sm">Small</Component>
<Component size="md">Medium</Component>
<Component size="lg">Large</Component>

**Demo layout helpers:**

| Component | Use when |
|-----------|----------|
| `<Storybook.Demo>` | Default; horizontally arranges examples |
| `<Storybook.Grid>` | Grid layout for many variants |
| `<Storybook.SideBySide>` | Two-column comparisons (do/don't) |
| `<Storybook.TokenReference>` | Displaying design tokens (spacing, color, etc.) |
| `<Storybook.ColorReference>` | Displaying color tokens specifically |

### Accessibility section

```mdx
## Accessibility

This component meets [WCAG 2.2 AA](https://www.w3.org/TR/WCAG22/) standards:

- **Color contrast**: Meets 4.5:1 ratio (WCAG 1.4.3)
- **Keyboard navigation**: <what interactions are supported>
- **Screen reader support**: <ARIA role and labeling behavior>

### Developer responsibilities

- Always provide <required accessible prop> (e.g., `aria-label` or visible label text)
- <other requirement>

> [!TIP]
> Use the `<prop>` prop when you need <use case>.

> [!WARNING]
> Avoid <pattern> because <reason>.

> [!NOTE]
>
> <Additional context.>

## Props

| Prop      | Type                              | Default  | Description               |
| --------- | --------------------------------- | -------- | ------------------------- |
| `variant` | `'info' \| 'warning' \| 'danger'` | `'info'` | Controls the visual style |
| `size`    | `'sm' \| 'md' \| 'lg'`            | `'md'`   | Controls the size         |

export {documentation};

To create a basic alert, wrap a message in `<Alert>` and specify the appropriate type.

```jsx
<Alert variant="info">This is an informational message</Alert>
```

<Alert.Container>
  <Alert variant="muted">Muted</Alert>
  <Alert variant="info">Info</Alert>
  <Alert variant="warning">Warning</Alert>
  <Alert variant="success">Success</Alert>
  <Alert variant="danger">Danger</Alert>
</Alert.Container>
