| 8 | +Package name: `@cube-dev/ui-kit` |
| 9 | + |
| 10 | +# Project Structure |
| 11 | + |
| 12 | +## Component file structure (preferable) |
| 13 | + |
| 14 | +/src/components/{category}/{ComponentName}/ |
| 15 | +- {ComponentName}.tsx – implementation of the component |
| 16 | +- {ComponentName}.docs.mdx - documentation |
| 17 | +- {ComponentName}.stories.tsx - Storybook stories |
| 18 | +- {ComponentName}.test.tsx - Unit tests |
| 19 | +- index.tsx - re-export of all instances |
| 20 | + |
| 21 | +## Icons |
| 22 | + |
| 23 | +/src/icons/ |
| 24 | + |
| 25 | +# Commands |
| 26 | + |
| 27 | +## Test |
| 28 | + |
| 29 | +All tests: `$ pnpm test` |
| 30 | +Specific test: `$ pnpm test -- {TestFileName}` |
| 31 | + |
| 32 | +## Build |
| 33 | + |
| 34 | +`pnpm run build` |
| 35 | + |
| 36 | +## Lint + Fix |
| 37 | + |
| 38 | +`pnpm run fix` |
| 39 | + |
| 40 | +# Stack |
| 41 | + |
| 42 | +- `tasty` style helper. |
| 43 | + - `src/tasty` - sources |
| 44 | + - `src/stories/Tasty.docs.mdx` - documentation |
| 45 | + - `src/stories/Styles.docs.mdx` - custom tasty styles documentation |
| 46 | + - `src/stories/CreateComponent.docs.mdx` - create components using tasty helper. |
| 47 | +- Storybook v8.6 |
| 48 | +- React and React DOM v18 |
| 49 | +- `styled-components` v6 |
| 50 | +- `react-aria` and `react-stately` with the latest versions. |
| 51 | +- `tabler/icons-react` - icons. |
| 52 | + |
| 53 | +# Recomendations |
| 54 | + |
| 55 | +- Use `DOCUMENTATION_GUIDELINES.md` for writing documentation for components. |
| 56 | +- Use icons from `/src/icons` if they have a required one. If not - use `tabler/icons-react`. If we need to customize the size or color of the icon, then wrap it with `<Icon/>` component and pass all required props there. Do not add any props to the tabler icons directly. |
| 57 | + |
| 58 | +## Form System |
| 59 | + |
| 60 | +- Form validation uses async rule-based system with built-in validators: |
| 61 | + - `required` - field is required |
| 62 | + - `type` - validates data type (email, url, number, etc.) |
| 63 | + - `pattern` - regex pattern validation |
| 64 | + - `min`/`max` - length/value constraints |
| 65 | + - `enum` - allowed values |
| 66 | + - `whitespace` - non-empty content |
| 67 | + - `validator` - custom async function |
| 68 | +- Form fields support direct integration without Field wrapper |
| 69 | +- Use `useForm` hook for form instance management |
| 70 | +- Form state includes validation, touched state, and error handling |
| 71 | + |
| 72 | +## Testing |
| 73 | + |
| 74 | +- Testing setup: Jest + React Testing Library + `@testing-library/react-hooks` |
| 75 | +- Test configuration: `src/test/setup.ts` with custom configurations |
| 76 | +- Testing utilities: `src/test/render.tsx` provides `renderWithRoot` wrapper |
| 77 | +- QA attributes: Use `qa` prop for e2e testing selectors (`data-qa`) |
| 78 | +- Test environment: Uses `jsdom` with React 18 act() environment |
| 79 | +- Coverage: Run `pnpm test-cover` for coverage reports |
| 80 | + |
| 81 | +## Accessibility |
| 82 | + |
| 83 | +- All components use React Aria hooks for accessibility |
| 84 | +- Keyboard navigation patterns are consistent across components |
| 85 | +- ARIA attributes are automatically managed by React Aria |
| 86 | +- Screen reader support is built-in with proper announcements |
| 87 | +- Focus management is handled automatically |
| 88 | +- Components support all standard ARIA labeling props |
| 89 | + |
| 90 | +## TypeScript |
| 91 | + |
| 92 | +- Interface naming: Use descriptive names with `Props` suffix for component props |
| 93 | +- Base props: Extend from `BaseProps` or `AllBaseProps` for standard properties |
| 94 | +- Form types: Use `FieldTypes` interface for form field type definitions |
| 95 | +- Style props: Use specific style prop interfaces (e.g., `ContainerStyleProps`) |
| 96 | +- Generic constraints: Use `extends` for type safety in form and field components |
| 97 | + |
| 98 | +## Component Architecture |
| 99 | + |
| 100 | +- Use `filterBaseProps` to separate design system props from DOM props |
| 101 | +- Export pattern: Use barrel exports with compound components (e.g., `Button.Group`) |
| 102 | +- Style system: Use `extractStyles` for separating style props from other props |
| 103 | +- Modifiers: Use `mods` prop for state-based styling |
| 104 | +- Sub-elements: Use `data-element` attribute for targeting specific parts in styles |
| 105 | + |
| 106 | +## Style System (Tasty) |
| 107 | + |
| 108 | +- Use `tasty` documentation |
| 109 | +- Use `tasty` custom styles with tasty syntax when possible. |
| 110 | +- Use `style` property only for dynamic styles and tokens (css custom properties). |
| 111 | +- Style categories: BASE, POSITION, BLOCK, COLOR, TEXT, DIMENSION, FLOW, CONTAINER, OUTER |
| 112 | +- Responsive values: Use arrays for breakpoint-based styling |
| 113 | +- Modifiers: Use object syntax for conditional styles |
| 114 | +- Sub-elements: Target inner elements using capitalized keys in styles |
| 115 | +- Style props: Direct style application without `styles` prop |
| 116 | +- CSS custom properties: Use `@token-name` syntax for design tokens |
| 117 | +- To declare a CSS animation use `styled-components` and then pass the animation name to the tasty styles. |
| 118 | + |
| 119 | +## Export Patterns |
| 120 | + |
| 121 | +- Compound components: Use `Object.assign` pattern for sub-components |
| 122 | +- Barrel exports: Each category has index.ts for re-exports |
| 123 | +- Main export: All components exported from `src/index.ts` |
| 124 | +- Type exports: Export component prop types for external use |
| 125 | + |
| 126 | +## Development Workflow |
| 127 | + |
| 128 | +- Branch naming: `[type/(task-name | scope)]` (e.g., `feat/button-group`) |
| 129 | +- Commit convention: `category: message` format |
| 130 | +- Changesets: Use `pnpm changeset` for version management |
| 131 | +- Code snippets: Use `jsx live=false` for documentation snippets |
| 132 | +- Storybook: Two modes - `stories` and `docs` for different outputs |
| 133 | + |
| 134 | +## Performance |
| 135 | + |
| 136 | +- Icon optimization: Reuse icon components, wrap with `<Icon/>` for customization |
| 137 | +- Style caching: Tasty system includes built-in style caching |
| 138 | +- Bundle size: Monitor with `pnpm size` command |
| 139 | +- Lazy loading: Use dynamic imports for large components |
| 140 | + |
| 141 | +## Error Handling |
| 142 | + |
| 143 | +- Form validation: Async error handling with Promise-based validation |
| 144 | +- Console suppression: Test setup includes act() warning suppression |
| 145 | +- Error boundaries: Use proper error boundaries in complex components |
| 146 | +- Validation state: Use `validationState` prop for field error states |
