Contributing

We welcome contributions to the Fonts package! This package manages web fonts and @font-face definitions.

Development Setup

cd packages/fonts
npm install
npm run build  # Process fonts and generate CSS

Structure

src/
├── fonts/              # Font files (woff2, woff, etc.)
└── font-faces.scss     # @font-face definitions

Font Configuration

Font metadata is defined in fonts.json:

{
  "fonts": [
    {
      "family": "Riverty Sans",
      "weight": 400,
      "style": "normal",
      "files": {
        "woff2": "riverty-sans-regular.woff2",
        "woff": "riverty-sans-regular.woff"
      }
    }
  ]
}

Working with Fonts

• Adding new font files:

  • Place font files in src/fonts/
  • Update fonts.json with metadata
  • Run npm run build

• Testing font loading:

  npm run build
  cd ../website
  npm run start
  

• Verify @font-face declarations:

  • Check generated files in lib/
  • Test loading in different browsers
  • Verify fallback behavior

Best Practices

• Maintain font file integrity (don't modify font files directly)
• Update font metadata accurately
• Include multiple formats (woff2, woff) for browser support
• Optimize font files for web (subset if possible)
• Test @font-face declarations
• Verify CDN compatibility
• Document font licensing
• Test font loading performance

Font Formats

Supported formats (in order of preference):

• WOFF2 - Modern format, best compression
• WOFF - Fallback for older browsers

Testing

# Build fonts
npm run build

# Verify artifacts (if available)
npm run verify:artifacts

Useful Commands

• npm run build - Process fonts and generate CSS
• npm run verify:artifacts - Verify build outputs
