Story Patterns

Component Story Format (CSF3)

 * ## Usage
 * ```tsx
 * import { Button } from '@mylib/components';
 *
 * <Button variant="primary" onClick={handleClick}>
 *   Click me
 * </Button>
 * ```
 *
 * ## Accessibility
 * - Uses native button element for proper semantics
 * - Supports keyboard navigation
 * - Includes ARIA attributes for loading/disabled states
 */

MDX Documentation

{/* Button.mdx */}
import { Meta, Canvas, Controls, Stories, Story } from '@storybook/blocks';
import * as ButtonStories from './Button.stories';
import { Button } from './Button';

<Meta of={ButtonStories} />

# Button

<Canvas of={ButtonStories.Primary} />

The Button component is used for triggering actions in forms, dialogs,
and throughout the interface.

## Import

```tsx
import { Button } from '@mylib/components';

Usage

<Button variant="primary" onClick={handleClick}>
  Click me
</Button>

Props

<Controls />

Variants

Primary

Use the primary variant for the main action on a page.

<Canvas of={ButtonStories.Primary} />

Secondary

Use secondary for less prominent actions.

<Canvas of={ButtonStories.Secondary} />

Danger

Use danger variant for destructive actions. Always confirm with users.

<Canvas of={ButtonStories.Danger} />

States

Loading

Display a loading spinner when an action is in progress.

<Canvas of={ButtonStories.Loading} />

Disabled

Disable buttons when actions are not available.

<Canvas of={ButtonStories.Disabled} />

Sizes

<Canvas of={ButtonStories.Sizes} />

Accessibility

• Uses semantic <button> element
• Supports keyboard focus and activation
• Includes aria-disabled when disabled
• Loading state announced to screen readers

Design Guidelines

Do

• Use clear, action-oriented labels
• Show loading state for async actions
• Disable when action is unavailable

Don't

• Don't use for navigation (use Link)
• Don't stack multiple primary buttons
• Don't disable without explanation

All Stories

<Stories /> ```

Autodocs Configuration

Per-Component Autodocs

// Component with JSDoc for autodocs
import { FC, ReactNode } from 'react';

export interface CardProps {
  /** Card title displayed in header */
  title: string;
  /** Optional subtitle below title */
  subtitle?: string;
  /** Card content */
  children: ReactNode;
  /** Visual variant */
  variant?: 'elevated' | 'outlined' | 'filled';
  /** Whether card is interactive/clickable */
  interactive?: boolean;
  /** Click handler for interactive cards */
  onClick?: () => void;
}

/**
 * Card component for grouping related content.
 *
 * @example
 * ```tsx
 * <Card title="Welcome" variant="elevated">
 *   <p>Card content goes here</p>
 * </Card>
 * ```
 */
export const Card: FC<CardProps> = ({
  title,
  subtitle,
  children,
  variant = 'elevated',
  interactive = false,
  onClick,
}) => {
  // Implementation
};

Autodocs Customization

// Card.stories.tsx
import type { Meta, StoryObj } from '@storybook/react';
import { Card } from './Card';

const meta: Meta<typeof Card> = {
  title: 'Components/Card',
  component: Card,
  tags: ['autodocs'],
  parameters: {
    docs: {
      description: {
        component: `
Cards are surfaces that display content and actions on a single topic.

They should be easy to scan for relevant and actionable information.
Elements, like text and images, should be placed on them in a way
that clearly indicates hierarchy.
        `,
      },
    },
  },
  argTypes: {
    children: {
      control: 'text',
      description: 'Card content',
      table: {
        category: 'Content',
      },
    },
    title: {
      table: {
        category: 'Content',
      },
    },
    variant: {
      table: {
        category: 'Appearance',
      },
    },
    interactive: {
      table: {
        category: 'Behavior',

Accessibility Addon Integration

A11y Configuration

// .storybook/preview.ts
import type { Preview } from '@storybook/react';

const preview: Preview = {
  parameters: {
    a11y: {
      config: {
        rules: [
          { id: 'color-contrast', enabled: true },
          { id: 'label', enabled: true },
          { id: 'button-name', enabled: true },
        ],
      },
      options: {
        runOnly: {
          type: 'tag',
          values: ['wcag2a', 'wcag2aa', 'wcag21a', 'wcag21aa'],
        },
      },
    },
  },
};

export default preview;

Per-Story A11y

export const AccessibleButton: Story = {
  args: {
    children: 'Submit Form',
    'aria-label': 'Submit the contact form',
  },
  parameters: {
    a11y: {
      config: {
        rules: [{ id: 'color-contrast', enabled: true }],
      },
    },
  },
};

Static Export

Build Documentation

# Build static documentation site
npx storybook build --docs -o docs/components

# With custom output
npx storybook build --docs -o public/design-system

package.json Scripts

{
  "scripts": {
    "storybook": "storybook dev -p 6006",
    "build-storybook": "storybook build",
    "build-docs": "storybook build --docs -o docs/components",
    "test-storybook": "test-storybook"
  }
}

Workflow

1. Analyze components - Scan for React/Vue/Angular components
2. Generate stories - Create story files for components
3. Extract props - Use react-docgen for prop documentation
4. Create MDX - Generate MDX documentation pages
5. Configure autodocs - Set up automatic documentation
6. Build static - Export static documentation site
