Design Tokens Deep Dive

Overview

Design tokens are the atomic values of a design system - the smallest pieces that define visual style. They bridge the gap between design and development by providing a single source of truth for colors, typography, spacing, and other design decisions.

Token Categories

Color Tokens

Token Naming Conventions

Recommended Structure

[category]-[property]-[variant]-[state]

Examples:
- color-background-default
- color-text-primary
- color-border-input-focus
- spacing-component-padding
- typography-heading-lg

Naming Guidelines

Use kebab-case: text-primary not textPrimary
Be descriptive: button-padding-horizontal not btn-px
Use semantic names: danger not red
Include scale info: spacing-4 or font-size-lg
State suffixes: -hover, -focus, -active, -disabled

Token Transformations

Style Dictionary Transforms

const StyleDictionary = require('style-dictionary');

// Custom transform for px to rem
StyleDictionary.registerTransform({
  name: 'size/pxToRem',
  type: 'value',
  matcher: (token) => token.attributes.category === 'size',
  transformer: (token) => {
    const value = parseFloat(token.value);
    return `${value / 16}rem`;
  },
});

// Custom format for CSS custom properties
StyleDictionary.registerFormat({
  name: 'css/customProperties',
  formatter: function({ dictionary, options }) {
    const tokens = dictionary.allTokens.map(token => {
      const name = token.name.replace(/\./g, '-');
      return `  --${name}: ${token.value};`;
    });

    return `:root {\n${tokens.join('\n')}\n}`;
  },
});

Platform-Specific Outputs

// iOS Swift output
public enum DesignTokens {
    public enum Color {
        public static let gray50 = UIColor(hex: "#fafafa")
        public static let gray900 = UIColor(hex: "#171717")
        public static let blue500 = UIColor(hex: "#3b82f6")

        public static let space2: CGFloat = 8
        public static let space4: CGFloat = 16
    }

    <dimen name="spacing_2">8dp</dimen>
    <dimen name="spacing_4">16dp</dimen>
</resources>

Token Governance

Change Management

Propose: Document the change and rationale
Review: Design and engineering review
Test: Validate across all platforms
Communicate: Announce changes to consumers
Deprecate: Mark old tokens, provide migration path
Remove: After deprecation period

Deprecation Pattern

{
  "color": {
    "primary": {
      "value": "{color.primitive.blue.500}",
      "deprecated": true,
      "deprecatedMessage": "Use accent.default instead",
      "replacedBy": "semantic.accent.default"
    }
  }
}

Token Validation

interface TokenValidation {
  checkContrastRatios(): ContrastReport;
  validateReferences(): ReferenceReport;
  detectCircularDeps(): CircularDepReport;
  auditNaming(): NamingReport;
}

// Contrast validation
function validateContrast(
  foreground: string,
  background: string,
  level: 'AA' | 'AAA' = 'AA'
): boolean {
  const ratio = getContrastRatio(foreground, background);
  return level === 'AA' ? ratio >= 4.5 : ratio >= 7;
}
