Storybook Setup

Configure Storybook for comprehensive component documentation and testing.

Core Workflow

1. Initialize Storybook : Setup with framework
2. Configure addons : Controls, actions, a11y
3. Write stories : Document components
4. Add documentation : MDX pages
5. Setup testing : Visual regression
6. Deploy docs : Static hosting

Installation

# Initialize Storybook
npx storybook@latest init

# Or with specific framework
npx storybook@latest init --type react
npx storybook@latest init --type nextjs
npx storybook@latest init --type vue3

Writing Stories

Component Story Format (CSF3)

// src/components/Button/Button.stories.tsx
import type { Meta, StoryObj } from '@storybook/react';
import { fn } from '@storybook/test';
import { Button } from './Button';

const meta = {
  title: 'Components/Button',
  component: Button,
  parameters: {
    layout: 'centered',
    docs: {
      description: {
        component: 'A versatile button component with multiple variants and sizes.',
      },
    },
  },
  tags: ['autodocs'],
  argTypes: {
    variant: {
      control: 'select',
      options: ['primary', 'secondary', 'outline', 'ghost'],
      description: 'Visual style variant',
      table: {
        type: { summary: 'string' },
        defaultValue: { summary: 'primary' },
      },
    },
    size: {
      control: 'radio',
      options: ['sm', 'md', 'lg'],
      description: 'Button size',
    },
    disabled: {
      control: 'boolean',
      description: 'Disable the button',
    },
    loading: {
      control: 'boolean',
      description: 'Show loading state',
    },
    children: {
      control: 'text',
      description: 'Button content',
    },
  },
  args: {
    onClick: fn(),
    children: 'Button',
  },
} satisfies Meta<typeof Button>;

export default meta;
type Story = StoryObj<typeof meta>;

// Basic stories
export const Primary: Story = {
  args: {
    variant: 'primary',
  },
};

export const Secondary: Story = {
  args: {
    variant: 'secondary',
  },
};

export const Outline: Story = {
  args: {
    variant: 'outline',
  },
};

export const Ghost: Story = {
  args: {
    variant: 'ghost',
  },
};

// Size variants
export const Small: Story = {
  args: {
    size: 'sm',
  },
};

export const Large: Story = {
  args: {
    size: 'lg',
  },
};

// States
export const Disabled: Story = {
  args: {
    disabled: true,
  },
};

export const Loading: Story = {
  args: {
    loading: true,
  },
};

// With icons
export const WithIcon: Story = {
  args: {
    children: (
      <>
        <PlusIcon className="mr-2 h-4 w-4" />
        Add Item
      </>
    ),
  },
};

// All variants showcase
export const AllVariants: Story = {
  render: () => (
    <div className="flex flex-wrap gap-4">
      <Button variant="primary">Primary</Button>
      <Button variant="secondary">Secondary</Button>
      <Button variant="outline">Outline</Button>
      <Button variant="ghost">Ghost</Button>
    </div>
  ),
};

Interactive Stories

// src/components/Form/Form.stories.tsx
import type { Meta, StoryObj } from '@storybook/react';
import { within, userEvent, expect, fn } from '@storybook/test';
import { Form } from './Form';

const meta: Meta<typeof Form> = {
  title: 'Components/Form',
  component: Form,
  args: {
    onSubmit: fn(),
  },
};

export default meta;
type Story = StoryObj<typeof meta>;

export const FilledForm: Story = {
  play: async ({ canvasElement, args }) => {
    const canvas = within(canvasElement);

    // Fill out the form
    const emailInput = canvas.getByLabelText('Email');
    await userEvent.type(emailInput, 'test@example.com', { delay: 50 });

    const passwordInput = canvas.getByLabelText('Password');
    await userEvent.type(passwordInput, 'password123', { delay: 50 });

    // Submit the form
    const submitButton = canvas.getByRole('button', { name: /submit/i });
    await userEvent.click(submitButton);

    // Assert the form was submitted
    await expect(args.onSubmit).toHaveBeenCalled();
  },
};

export const ValidationError: Story = {
  play: async ({ canvasElement }) => {
    const canvas = within(canvasElement);

    // Submit without filling
    const submitButton = canvas.getByRole('button', { name: /submit/i });
    await userEvent.click(submitButton);

    // Check for error messages
    await expect(canvas.getByText('Email is required')).toBeInTheDocument();
  },
};

# Button

The Button component is used to trigger actions or navigation.

## Import

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

Usage

Variants

Buttons come in four variants to communicate different levels of emphasis.

Primary

Use for primary actions that are the main call to action on a page.

Secondary

Use for secondary actions that complement the primary action.

Outline

Use for tertiary actions or when you want less visual emphasis.

Ghost

Use for navigation or very subtle actions.

Sizes

States

Disabled

Loading

Props

Accessibility

• Buttons use the native <button> element
• Loading state announces to screen readers
• Focus states are clearly visible
• Disabled buttons maintain proper ARIA attributes

Design Guidelines

1. Use descriptive button text
2. Limit to one primary button per section
3. Keep button text concise (2-4 words)
4. Use icons to reinforce meaning, not replace text

## Testing Integration

### Visual Regression with Chromatic

```typescript
// .storybook/main.ts
const config: StorybookConfig = {
  addons: [
    '@chromatic-com/storybook',
  ],
};



// package.json
{
  "scripts": {
    "chromatic": "chromatic --project-token=$CHROMATIC_PROJECT_TOKEN"
  }
}

Test Runner

npm install @storybook/test-runner -D



// .storybook/test-runner.ts
import type { TestRunnerConfig } from '@storybook/test-runner';
import { getStoryContext } from '@storybook/test-runner';
import { injectAxe, checkA11y } from 'axe-playwright';

const config: TestRunnerConfig = {
  async preVisit(page) {
    await injectAxe(page);
  },
  async postVisit(page, context) {
    // Run accessibility tests
    const storyContext = await getStoryContext(page, context);
    if (!storyContext.parameters?.a11y?.disable) {
      await checkA11y(page, '#storybook-root', {
        detailedReport: true,
        detailedReportOptions: { html: true },
      });
    }
  },
};

export default config;



// package.json
{
  "scripts": {
    "test-storybook": "test-storybook",
    "test-storybook:ci": "test-storybook --ci"
  }
}

Design Tokens Integration

// .storybook/preview.ts
import { ThemeProvider } from 'styled-components';
import { theme } from '../src/styles/theme';

const preview: Preview = {
  decorators: [
    (Story) => (
      <ThemeProvider theme={theme}>
        <Story />
      </ThemeProvider>
    ),
  ],
};



// src/styles/theme.ts (document in Storybook)
export const theme = {
  colors: {
    primary: {
      50: '#eff6ff',
      500: '#3b82f6',
      900: '#1e3a8a',
    },
  },
  spacing: {
    xs: '0.25rem',
    sm: '0.5rem',
    md: '1rem',
    lg: '1.5rem',
    xl: '2rem',
  },
  radii: {
    sm: '0.25rem',
    md: '0.375rem',
    lg: '0.5rem',
    full: '9999px',
  },
};

Publishing

Static Export

// package.json
{
  "scripts": {
    "build-storybook": "storybook build",
    "storybook:serve": "npx http-server storybook-static"
  }
}

Best Practices

1. One component per file : Clear organization
2. Use autodocs : Generate documentation
3. Add controls : Interactive exploration
4. Include a11y addon : Accessibility testing
5. Write play functions : Interactive tests
6. Document with MDX : Rich documentation
7. Use decorators : Consistent context
8. Visual regression : Catch UI changes

Output Checklist

Every Storybook setup should include:

• Main configuration with addons
• Preview with global decorators
• Stories in CSF3 format
• Autodocs enabled
• Controls for all props
• Accessibility addon
• Dark mode support
• Viewport presets
• MDX documentation
• Test runner setup
• CI deployment
• Static build script
