Building Design System Components

NEW COMPONENT CHECKLIST:
□ Base component designed in Figma
□ Variants mapped to props system
□ Documentation written (usage, do/don't, a11y)
□ Code Connect mapping configured
□ Storybook stories created
□ Version impact assessed
□ QA approval obtained

FIGMA STRUCTURE:
Button (Base) → Primary/Secondary (Variants) → Login Button (Instance)

Phase 1: Figma Foundation

• Create base component with core functionality
• Define variant structure (size, state, type)
• Set up component properties (boolean, enum, text, instance swap)
• Test all variant combinations work correctly

Phase 2: Props System Design

PROP TYPES:
- Boolean: enabled/disabled, loading, full-width
- Enum: size (sm/md/lg), variant (primary/secondary)
- Text: label, placeholder, helper text
- Instance Swap: icon, avatar, nested components

Phase 3: Documentation

• Write usage guidelines with context
• Create do/don't examples with visuals
• Document accessibility requirements (ARIA, keyboard nav)
• Specify responsive behavior

Phase 4: Code Integration

• Configure Figma Code Connect mapping
• Create Storybook stories for all variants
• Set up interactive controls for props testing
• Validate design-code parity

Phase 5: Release Management

• Assess version impact (patch/minor/major)
• Update migration guide if breaking
• Communicate changes to team
• Monitor adoption metrics

Example 1: Button Component Input: Need a flexible button for web app Output:

FIGMA STRUCTURE:
├── Button (Base)
    ├── Primary (Variant)
    ├── Secondary (Variant)  
    ├── Ghost (Variant)
    └── Destructive (Variant)

PROPS:
- size: enum (sm, md, lg)
- disabled: boolean
- loading: boolean
- icon: instance swap
- label: text

DOCUMENTATION:
Usage: Primary for main actions, Secondary for supporting actions
Do: Use consistent sizing within action groups
Don't: Mix button variants randomly in same context
A11y: Min 44px touch target, focus indicators, loading states

Example 2: Code Connect Mapping Input: Button component ready for code connection Output:

JavaScript
// figma.connect.tsx
figma.connect(Button, "https://figma.com/button-component", {
  props: {
    variant: figma.enum("Type", {
      Primary: "primary",
      Secondary: "secondary"
    }),
    size: figma.enum("Size", {
      Small: "sm",
      Medium: "md", 
      Large: "lg"
    }),
    disabled: figma.boolean("Disabled"),
    children: figma.string("Label")
  },
  example: ({ variant, size, disabled, children }) => (
    <Button variant={variant} size={size} disabled={disabled}>
      {children}
    </Button>
  )
})
