Design Tokens Table

Format

The design tokens table must document all CSS variables used in the component:

## Design Tokens

| Token | CSS Variable | Usage | Preview |
|-------|--------------|-------|---------|
| Background Primary | \`--semantic-bg-primary\` | Component background | <div style="width: 20px; height: 20px; background: var(--semantic-bg-primary); border: 1px solid #ccc;"></div> |
| Text Primary | \`--semantic-text-primary\` | Primary text color | <span style="color: var(--semantic-text-primary);">Aa</span> |
| Border Layout | \`--semantic-border-layout\` | Container borders | <div style="width: 40px; height: 2px; background: var(--semantic-border-layout);"></div> |

How to Generate

1. Extract CSS variables from component code :

   // From this code:
   className="bg-primary text-primary-foreground border-input"
   
   // Extract these variables:
   - --primary (bg-primary)
   - --primary-foreground (text-primary-foreground)
   - --input (border-input)
   

2. Categorize by usage :

   • Backgrounds: bg-* classes
   • Text colors: text-* classes
   • Borders: border-* classes
   • Other: Shadows, rings, etc.

3. Add appropriate preview :

   • Backgrounds: Color swatch (20x20px div)
   • Text: "Aa" sample with color
   • Borders: Line sample (40x2px div)

Examples

Example 1: Button Component

## Design Tokens

| Token | CSS Variable | Usage | Preview |
|-------|--------------|-------|---------|
| Primary | \`--primary\` | Primary button background | <div style="width: 20px; height: 20px; background: var(--primary); border-radius: 4px;"></div> |
| Primary Foreground | \`--primary-foreground\` | Text on primary button | <span style="color: var(--primary-foreground);">Aa</span> |
| Secondary | \`--secondary\` | Secondary button background | <div style="width: 20px; height: 20px; background: var(--secondary); border-radius: 4px;"></div> |
| Destructive | \`--destructive\` | Destructive button background | <div style="width: 20px; height: 20px; background: var(--destructive); border-radius: 4px;"></div> |
| Border | \`--border\` | Outline variant border | <div style="width: 40px; height: 2px; background: var(--border);"></div> |

Example 2: AlertConfiguration Component

## Design Tokens

| Token | CSS Variable | Usage | Preview |
|-------|--------------|-------|---------|
| Border Layout | \`--semantic-border-layout\` | Container border, dividers | <div style="width: 40px; height: 2px; background: var(--semantic-border-layout);"></div> |
| Background Primary | \`--semantic-bg-primary\` | Component background | <div style="width: 20px; height: 20px; background: var(--semantic-bg-primary); border: 1px solid #ccc;"></div> |
| Text Primary | \`--semantic-text-primary\` | Labels and values | <span style="color: var(--semantic-text-primary);">Aa</span> |
| Text Muted | \`--semantic-text-muted\` | Descriptions | <span style="color: var(--semantic-text-muted);">Aa</span> |
| Text Link | \`--semantic-text-link\` | Top-up amount (blue) | <span style="color: var(--semantic-text-link);">Aa</span> |
| Error Primary | \`--semantic-error-primary\` | Negative balance (red) | <span style="color: var(--semantic-error-primary);">Aa</span> |

Typography Table

Format

Document font specifications for text elements in the component:

## Typography

| Element | Font Size | Line Height | Weight | Letter Spacing |
|---------|-----------|-------------|--------|----------------|
| Title | 16px (\`text-base\`) | 24px (\`leading-6\`) | 600 (\`font-semibold\`) | 0px (\`tracking-[0px]\`) |
| Subtitle | 14px (\`text-sm\`) | 20px (\`leading-5\`) | 400 (\`font-normal\`) | 0.035px (\`tracking-[0.035px]\`) |

How to Generate

1. Identify text elements :

   • Titles/headers
   • Body text
   • Labels
   • Descriptions
   • Captions

2. Extract Tailwind classes :

   // From this code:
   <h3 className="text-base font-semibold tracking-[0px]">
   
   // Extract:
   - Font Size: 16px (text-base)
   - Weight: 600 (font-semibold)
   - Letter Spacing: 0px (tracking-[0px])
   

3. Map to actual values :

   text-sm = 14px
   text-base = 16px
   text-lg = 18px
   
   font-normal = 400
   font-medium = 500
   font-semibold = 600
   font-bold = 700
   
   leading-tight = 1.25
   leading-normal = 1.5
   leading-relaxed = 1.625
   

Example

AlertConfiguration Typography:

## Typography

| Element | Font Size | Line Height | Weight | Letter Spacing |
|---------|-----------|-------------|--------|----------------|
| Title | 16px (\`text-base\`) | 24px (\`leading-6\`) | 600 (\`font-semibold\`) | 0px (\`tracking-[0px]\`) |
| Description | 14px (\`text-sm\`) | 20px (\`leading-relaxed\`) | 400 (\`font-normal\`) | 0.035px (\`tracking-[0.035px]\`) |
| Label | 14px (\`text-sm\`) | 20px | 600 (\`font-semibold\`) | 0.014px (\`tracking-[0.014px]\`) |
| Value | 14px (\`text-sm\`) | 20px | 400 (\`font-normal\`) | 0.035px (\`tracking-[0.035px]\`) |

Usage Examples

Basic Usage

<Component variant="primary" size="lg">
  Content
</Component>

Advanced Usage

Show composition patterns, controlled state, callbacks:

const [open, setOpen] = useState(false)

<Component
  open={open}
  onOpenChange={setOpen}
  variant="primary"
  onAction={handleAction}
>
  <ComponentContent />
</Component>

With Form Integration

const [value, setValue] = useState('')

<FormModal
  open={isOpen}
  onOpenChange={setIsOpen}
  title="Edit Values"
  onSave={handleSave}
>
  <TextField
    label="Name"
    value={value}
    onChange={(e) => setValue(e.target.value)}
  />
</FormModal>

Interactive Stories

Create stories for each variant and use case:

1. Default Story

export const Default: Story = {
  args: {
    children: 'Component',
  },
}

2. Variant Stories

export const Primary: Story = {
  args: {
    variant: 'primary',
    children: 'Primary Component',
  },
}

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

export const Destructive: Story = {
  args: {
    variant: 'destructive',
    children: 'Destructive Component',
  },
}

3. Size Stories

export const Small: Story = {
  args: {
    size: 'sm',
    children: 'Small Component',
  },
}

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

4. Interactive Stories

export const WithState: Story = {
  render: () => {
    const [open, setOpen] = React.useState(false)

    return (
      <>
        <Button onClick={() => setOpen(true)}>
          Open Component
        </Button>
        <Component
          open={open}
          onOpenChange={setOpen}
        />
      </>
    )
  },
}

5. Showcase Stories

export const AllVariants: Story = {
  render: () => (
    <div className="flex flex-col gap-4">
      <div className="flex gap-2">
        <Component variant="default">Default</Component>
        <Component variant="primary">Primary</Component>
        <Component variant="secondary">Secondary</Component>
      </div>
      <div className="flex gap-2">
        <Component size="sm">Small</Component>
        <Component size="default">Default</Component>
        <Component size="lg">Large</Component>
      </div>
    </div>
  ),
}

6. State Stories

export const States: Story = {
  render: () => (
    <div className="flex flex-col gap-4">
      <Component>Normal</Component>
      <Component disabled>Disabled</Component>
      <Component loading>Loading</Component>
    </div>
  ),
}

7. Multi-State Stories (from State Inventory Table)

If the component has a State Inventory Table from Phase 2, create a story for each visual state :

// Example: WalletTopup has Default, No Preselection, Loading, and Disabled states
export const Default: Story = {
  args: {
    amounts: [100, 200, 500],
    selectedAmount: 100,
  },
}

export const NoPreselection: Story = {
  args: {
    amounts: [100, 200, 500],
    // no selectedAmount — tests empty/initial state
  },
}

export const Loading: Story = {
  args: {
    amounts: [100, 200, 500],
    isLoading: true,
  },
}

export const Disabled: Story = {
  args: {
    amounts: [100, 200, 500],
    disabled: true,
  },
}

Rules for multi-state stories:

• Every state in the State Inventory Table MUST have a corresponding story
• Name stories to match the state names (e.g., Success, Error, Empty)
• Show the visual difference clearly — don't just toggle a boolean, set all props that reflect that state
• If a state involves user interaction (e.g., after typing), use render with internal state

8. Domain-Specific Prop Stories

For components with domain-specific props (confirmed in Phase 5, Step 1e), create stories demonstrating key prop combinations:

// Example: WalletTopup has currency, voucherLink, amounts, headerIcon
export const DollarCurrency: Story = {
  args: {
    currency: '$',
    amounts: [10, 25, 50, 100],
  },
}

export const CustomVoucherIcon: Story = {
  args: {
    amounts: [100, 200, 500],
    headerIcon: <Gift className="h-5 w-5" />,
  },
}

export const NoVoucherLink: Story = {
  args: {
    amounts: [100, 200, 500],
    showVoucherLink: false,
  },
}

Rules for domain-specific prop stories:

• Cover each customization prop with at least one story
• Show non-obvious defaults (e.g., what happens when a prop is omitted)
• Use descriptive story names that explain the prop being demonstrated

ArgTypes Configuration

Document all props with descriptions and controls:

argTypes: {
  variant: {
    control: 'select',
    options: ['default', 'primary', 'secondary', 'destructive'],
    description: 'Visual style variant of the component',
    table: {
      defaultValue: { summary: 'default' },
      type: { summary: 'string' },
    },
  },
  size: {
    control: 'select',
    options: ['sm', 'default', 'lg', 'xl'],
    description: 'Size of the component',
    table: {
      defaultValue: { summary: 'default' },
      type: { summary: 'string' },
    },
  },
  disabled: {
    control: 'boolean',
    description: 'Disables the component interaction',
    table: {
      defaultValue: { summary: false },
      type: { summary: 'boolean' },
    },
  },
  loading: {
    control: 'boolean',
    description: 'Shows loading state',
    table: {
      defaultValue: { summary: false },
      type: { summary: 'boolean' },
    },
  },
  onAction: {
    action: 'clicked',
    description: 'Callback when action is triggered',
    table: {
      type: { summary: '() => void' },
    },
  },
}

Domain-Specific ArgTypes

For components with domain-specific props, document all three categories:

argTypes: {
  // Data props
  amounts: {
    control: 'object',
    description: 'Array of preset amounts to display',
    table: {
      type: { summary: 'number[]' },
      defaultValue: { summary: '[100, 200, 500, 1000]' },
    },
  },
  currency: {
    control: 'text',
    description: 'Currency symbol to display',
    table: {
      type: { summary: 'string' },
      defaultValue: { summary: '₹' },
    },
  },
  // Callback props
  onSubmit: {
    action: 'submitted',
    description: 'Called when user submits with the selected/entered amount',
    table: {
      type: { summary: '(amount: number) => void' },
    },
  },
  // Customization props
  headerIcon: {
    control: false,
    description: 'Custom icon for the header. Defaults to Wallet icon.',
    table: {
      type: { summary: 'React.ReactNode' },
    },
  },
}

Best Practices

1. Always include installation instructions - Help users get started
2. Document all CSS variables used - Enable customization
3. Show typography specifications - Ensure consistent implementation
4. Provide usage examples - Demonstrate common patterns
5. Create interactive stories - Let users explore variants
6. Use meaningful story names - Make documentation discoverable
7. Add descriptions to argTypes - Explain prop purposes
8. Show composition patterns - Teach proper usage
9. Include state examples - Cover disabled, loading, error states
10. Follow established patterns - Maintain consistency across docs

Validation Checklist

Before finalizing documentation:

• Installation section included
• Import statement shown
• Design tokens table complete (all CSS variables from actual component code)
• Typography table included (if applicable)
• Usage examples provided
• Default story created
• Variant stories created
• Size stories created
• Interactive stories added
• Multi-state stories — one per state in the State Inventory Table
• Domain-specific prop stories — key customization props demonstrated
• ArgTypes configured (including domain-specific props with categories)
• All stories render correctly
• Documentation is clear and helpful

Post-Implementation Verification

After the component is fully implemented (Phase 5 complete), re-check:

• Design Tokens table reflects actual CSS variables in the final component code (not just the planned ones)
• Typography table matches actual font classes used
• Docs page description accurately reflects final props (props may have changed during implementation)
• Stories demonstrate the component's real behavior (not placeholder args)
• Sidebar grouping is correct (Components/Name for UI, Custom/Name or Custom/SubGroup/Name for custom)

This skill ensures comprehensive, consistent documentation that helps users understand and use components effectively.
