(similar structure for all components) ├── hooks/ │ ├── useBreakpoint.ts │ └── useMediaQuery.ts ├── theme/ │ ├── ThemeProvider.tsx │ └── themes.ts └── index.ts ``` ### Key Implementation Patterns ```typescript // Button.types.ts export type ButtonVariant = 'primary' | 'secondary' | 'ghost' | 'destructive'; export type ButtonSize = 'sm' | 'md' | 'lg'; export interface ButtonProps extends React.ButtonHTMLAttributes { variant?: ButtonVariant; size?: ButtonSize; loading?: boolean; icon?: React.ReactNode; iconPosition?: 'left' | 'right'; } ``` ```typescript // ThemeProvider.tsx interface ThemeContextValue { theme: Theme; setTheme: (theme: Theme) => void; } const ThemeContext = React.createContext ({ theme: defaultTheme, setTheme: () => {}, }); export const ThemeProvider: React.FC = ({ theme = defaultTheme, children }) => { const [currentTheme, setCurrentTheme] = React.useState(theme); React.useEffect(() => { const root = document.documentElement; root.style.setProperty('--color-primary', currentTheme.colors.primary); // ... set all CSS custom properties }, [currentTheme]); return ( {children} ); }; ``` ## Commands ### Local Development ```bash # Install dependencies npm install # Start Storybook npm run storybook # Run tests npm run test # Run tests with coverage npm run test:coverage # Run accessibility tests npm run test:a11y # Build library npm run build # Type check npm run type-check # Lint npm run lint ``` ### CI Pipeline ```bash # Install dependencies npm ci # Type check npm run type-check # Lint npm run lint # Run unit tests npm run test:ci # Run accessibility tests npm run test:a11y:ci # Build library npm run build # Build Storybook npm run build-storybook # Visual regression tests npm run test:visual ``` ## Quality Assurance Task Checklist - [ ] Component APIs are consistent with existing library conventions - [ ] All components pass axe accessibility checks with zero violations - [ ] TypeScript compiles without errors and provides accurate autocompletion - [ ] Storybook builds successfully with all stories rendering correctly - [ ] Unit tests pass and cover logic, interactions, and edge cases - [ ] Bundle size impact is measured and within acceptable limits - [ ] SSR/SSG rendering produces no hydration warnings or errors - [ ] Design tokens are used exclusively (no hardcoded colors, sizes, or spacing) - [ ] Components support both controlled and uncontrolled usage patterns - [ ] Dark mode and high contrast modes are supported via theme switching - [ ] All components meet WCAG 2.1 AA accessibility standards - [ ] Visual regression tests guard against unintended style changes - [ ] Package exports are configured for tree-shaking (ESM and CJS) - [ ] Migration guides exist when replacing or deprecating components - [ ] Changelog follows semantic versioning with clear breaking change documentation
