Figma Token Integration

Overview

Sync design tokens between code and Figma using Figma Variables, the Tokens Studio plugin, or Style Dictionary. Establish a single source of truth workflow for design-to-code handoff.

When to Use

• Setting up Figma Variables from code tokens
• Exporting Figma styles to code tokens
• Establishing a design token workflow
• Syncing colors, typography, and spacing with Figma

Quick Reference: Figma Token Types

Figma Type	Maps To	Example
Color Variable	--color-*	--color-primary-500
Number Variable	--spacing-*, --radius-*	--spacing-md
String Variable	Font family, mode names	--font-sans
Boolean Variable	Feature flags	Theme mode toggles

The Process

1. Choose workflow direction:
   • Code → Figma (tokens are source of truth in code)
   • Figma → Code (designers own tokens in Figma)
   • Bidirectional (sync both ways)
2. Select tooling: Native Variables, Tokens Studio, or custom
3. Define token structure: Categories, naming, modes
4. Set up sync mechanism: Plugin, API, or manual
5. Document workflow: Who updates what, when to sync

Workflow Options

Approach	Best For	Tools
Figma Variables (native)	Simple setups, color/number tokens	Figma UI, REST API
Tokens Studio	Complex tokens, multi-file	Tokens Studio plugin + GitHub
Style Dictionary	Enterprise, CI/CD integration	Style Dictionary + Figma API
Manual sync	Small teams, infrequent changes	Copy/paste with conventions

Figma Variables (Native)

Creating Variables from Code Tokens

Token structure for Figma:

{
  "color": {
    "primary": {
      "50": { "value": "#eff6ff", "type": "color" },
      "100": { "value": "#dbeafe", "type": "color" },
      "500": { "value": "#3b82f6", "type": "color" },
      "900": { "value": "#1e3a8a", "type": "color" }
    },
    "gray": {
      "50": { "value": "#f9fafb", "type": "color" },
      "900": { "value": "#111827", "type": "color" }
    }
  },
  "spacing": {
    "xs": { "value": 4, "type": "number" },
    "sm": { "value": 8, "type": "number" },
    "md": { "value": 16, "type": "number" },
    "lg": { "value": 24, "type": "number" }
  },
  "radius": {
    "sm": { "value": 4, "type": "number" },
    "md": { "value": 8, "type": "number" },
    "lg": { "value": 16, "type": "number" },
    "full": { "value": 9999, "type": "number" }
  }
}

Figma REST API Example

Create variables via API:

import Anthropic from '@anthropic-ai/sdk'; // Example using Figma API

interface FigmaVariable {
  name: string;
  resolvedType: 'COLOR' | 'FLOAT' | 'STRING' | 'BOOLEAN';
  valuesByMode: Record<string, any>;
}

async function createFigmaVariables(
  fileKey: string,
  collectionName: string,
  tokens: Record<string, any>
): Promise<void> {
  const accessToken = process.env.FIGMA_ACCESS_TOKEN;

  // Step 1: Create variable collection
  const collectionResponse = await fetch(
    `https://api.figma.com/v1/files/${fileKey}/variables`,
    {
      method: 'POST',
      headers: {
        'X-Figma-Token': accessToken,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        variableCollections: [
          {
            action: 'CREATE',
            name: collectionName,
            initialModeId: 'light',
          },
        ],
      }),
    }
  );

  const { variableCollections } = await collectionResponse.json();
  const collectionId = variableCollections[0].id;

  // Step 2: Create variables
  const variables: FigmaVariable[] = [];

  for (const [category, values] of Object.entries(tokens)) {
    for (const [name, token] of Object.entries(values as Record<string, any>)) {
      variables.push({
        name: `${category}/${name}`,
        resolvedType: token.type === 'color' ? 'COLOR' : 'FLOAT',
        valuesByMode: {
          light: parseValue(token.value, token.type),
        },
      });
    }
  }

  await fetch(`https://api.figma.com/v1/files/${fileKey}/variables`, {
    method: 'POST',
    headers: {
      'X-Figma-Token': accessToken,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      variables: variables.map((v) => ({
        action: 'CREATE',
        variableCollectionId: collectionId,
        ...v,
      })),
    }),
  });
}

function parseValue(value: string | number, type: string): any {
  if (type === 'color') {
    // Convert hex to Figma RGBA
    const hex = value as string;
    const r = parseInt(hex.slice(1, 3), 16) / 255;
    const g = parseInt(hex.slice(3, 5), 16) / 255;
    const b = parseInt(hex.slice(5, 7), 16) / 255;
    return { r, g, b, a: 1 };
  }
  return value;
}

Variable Modes (Theming)

Light/dark mode setup:

{
  "variableCollections": [
    {
      "name": "Semantic Colors",
      "modes": [
        { "name": "Light", "modeId": "light" },
        { "name": "Dark", "modeId": "dark" }
      ]
    }
  ],
  "variables": [
    {
      "name": "background/default",
      "valuesByMode": {
        "light": { "type": "VARIABLE_ALIAS", "id": "color/gray/50" },
        "dark": { "type": "VARIABLE_ALIAS", "id": "color/gray/900" }
      }
    },
    {
      "name": "text/primary",
      "valuesByMode": {
        "light": { "type": "VARIABLE_ALIAS", "id": "color/gray/900" },
        "dark": { "type": "VARIABLE_ALIAS", "id": "color/gray/50" }
      }
    }
  ]
}

Tokens Studio → Code Transform

Style Dictionary config (sd.config.js):

module.exports = {
  source: ['tokens/**/*.json'],
  platforms: {
    css: {
      transformGroup: 'css',
      buildPath: 'dist/css/',
      files: [
        {
          destination: 'variables.css',
          format: 'css/variables',
          filter: (token) => token.filePath.includes('global'),
        },
        {
          destination: 'light.css',
          format: 'css/variables',
          filter: (token) => token.filePath.includes('light'),
          options: {
            selector: ':root, [data-theme="light"]',
          },
        },
        {
          destination: 'dark.css',
          format: 'css/variables',
          filter: (token) => token.filePath.includes('dark'),
          options: {
            selector: '[data-theme="dark"]',
          },
        },
      ],
    },
    tailwind: {
      transformGroup: 'js',
      buildPath: 'dist/',
      files: [
        {
          destination: 'tailwind.tokens.js',

Naming Conventions

Category	Figma Convention	Code Convention
Colors	color/primary/500	--color-primary-500
Spacing	spacing/md	--spacing-md
Radius	radius/lg	--radius-lg
Typography	text/body/regular	--text-body
Shadows	shadow/md	--shadow-md
Semantic	bg/default	--color-bg-default

Workflow Best Practices

1. Single source of truth: Decide if code or Figma owns tokens
2. Version control: Store token files in Git
3. CI/CD integration: Auto-sync on merge to main
4. Semantic tokens: Use aliases for theme-aware values
5. Documentation: Keep a mapping document for designers
6. Validation: Lint tokens before sync

Common Pitfalls

Issue	Solution
Color format mismatch	Normalize to hex or RGB before sync
Spacing units	Use unitless in Figma, add px/rem in code
Missing tokens	Validate token coverage before sync
Mode drift	Sync all modes together, not separately
Name collisions	Establish naming convention upfront
