# @canonical/launchpad-design-tokens

Design tokens for Canonical's Launchpad, providing consistent styling across the platform. This package generates CSS custom properties and Figma tokens from a centralized token system.

## Installation

```bash
npm install @canonical/launchpad-design-tokens
```

## Usage

### CSS Tokens

The package provides CSS files with custom properties for different categories:

#### Colors

- `dist/css/color/light.css` - Light mode colors
- `dist/css/color/dark.css` - Dark mode colors
- `dist/css/color/system.css` - System preference based colors

#### Typography

- `dist/css/typography/narrow.css` - Typography for narrow screens
- `dist/css/typography/medium.css` - Typography for medium screens
- `dist/css/typography/wide.css` - Typography for wide screens
- `dist/css/typography/extraWide.css` - Typography for extra wide screens
- `dist/css/typography/responsive.css` - Responsive typography system

#### Dimensions

- `dist/css/dimension/narrow.css` - Dimensions for narrow screens
- `dist/css/dimension/medium.css` - Dimensions for medium screens
- `dist/css/dimension/wide.css` - Dimensions for wide screens
- `dist/css/dimension/extraWide.css` - Dimensions for extra wide screens
- `dist/css/dimension/responsive.css` - Responsive dimension system

#### Opacity

- `dist/css/opacity/opacity.css` - Opacity levels for transparency effects

#### Transition

- `dist/css/transition/normal.css` - Standard transition timings
- `dist/css/transition/preferred.css` - Transitions based on prefers-motion setting
- `dist/css/transition/reduced-motion.css` - Transitions for reduced motion preferences

### Figma Tokens

Figma-compatible token files are available in `dist/figma/` with the same structure as CSS tokens, plus manifest files for easy import.

## Development

```bash
bun install
```

### Available Scripts

```bash
# Build all tokens
bun run build

# Build specific categories

bun run build:typography
bun run build:dimension
bun run build:opacity
bun run build:transition

# Run linting and type checking
bun run check

# Fix linting issues
bun run check:fix
```
