What this skill does

# Figma API Integration

Extract design data, generate code from components, and automate design workflows with Figma's API.

## Quick Start

### Authentication
```typescript
const FIGMA_TOKEN = process.env.FIGMA_TOKEN;

const headers = {
  'X-Figma-Token': FIGMA_TOKEN
};

// Get file
const response = await fetch(
  `https://api.figma.com/v1/files/${FILE_KEY}`,
  { headers }
);
```

### File Key & Node IDs
```typescript
// Extract from Figma URL: figma.com/file/FILE_KEY/Name?node-id=NODE_ID
const figmaUrl = 'https://www.figma.com/file/abc123/MyDesign?node-id=1%3A2';
const fileKey = figmaUrl.match(/file\/([^/]+)/)?.[1];  // abc123
const nodeId = new URL(figmaUrl).searchParams.get('node-id');  // 1:2
```

## Core API Endpoints

### Get File
```typescript
// Full file
GET https://api.figma.com/v1/files/:file_key

// Specific nodes (components)
GET https://api.figma.com/v1/files/:file_key/nodes?ids=1:2,1:3

// With geometry for SVG paths
GET https://api.figma.com/v1/files/:file_key?geometry=paths

// With plugin data
GET https://api.figma.com/v1/files/:file_key?plugin_data=shared
```

### Get Components
```typescript
// Get all components in a file
GET https://api.figma.com/v1/files/:file_key/components

// Get component sets (variants)
GET https://api.figma.com/v1/files/:file_key/component_sets

// Get team's published components
GET https://api.figma.com/v1/teams/:team_id/components
```

### Export Images
```typescript
// Export nodes as images
GET https://api.figma.com/v1/images/:file_key?ids=1:2,1:3&format=png&scale=2

// Export as SVG
GET https://api.figma.com/v1/images/:file_key?ids=1:2&format=svg

// Response
{
  "images": {
    "1:2": "https://s3.amazonaws.com/...",
    "1:3": "https://s3.amazonaws.com/..."
  }
}
```

## Component Code Generation

### Figma Node to React Component
```typescript
interface FigmaNode {
  id: string;
  name: string;
  type: string;
  children?: FigmaNode[];
  absoluteBoundingBox?: { x: number; y: number; width: number; height: number };
  fills?: Fill[];
  strokes?: Stroke[];
  effects?: Effect[];
  cornerRadius?: number;
  paddingLeft?: number;
  paddingRight?: number;
  paddingTop?: number;
  paddingBottom?: number;
  itemSpacing?: number;
  layoutMode?: 'HORIZONTAL' | 'VERTICAL' | 'NONE';
  primaryAxisAlignItems?: string;
  counterAxisAlignItems?: string;
  characters?: string;
  style?: TextStyle;
}

async function getComponentCode(fileKey: string, nodeId: string): Promise<string> {
  const response = await fetch(
    `https://api.figma.com/v1/files/${fileKey}/nodes?ids=${nodeId}`,
    { headers: { 'X-Figma-Token': process.env.FIGMA_TOKEN! } }
  );
  const data = await response.json();
  const node = data.nodes[nodeId].document;
  
  return generateReactComponent(node);
}

function generateReactComponent(node: FigmaNode): string {
  const componentName = toPascalCase(node.name);
  const styles = extractStyles(node);
  const children = node.children?.map(child => generateJSX(child)).join('\n') || '';
  
  return `
import React from 'react';

export function ${componentName}() {
  return (
    <div style={${JSON.stringify(styles, null, 2)}}>
      ${children}
    </div>
  );
}
`;
}

function extractStyles(node: FigmaNode): React.CSSProperties {
  const styles: React.CSSProperties = {};
  
  // Dimensions
  if (node.absoluteBoundingBox) {
    styles.width = node.absoluteBoundingBox.width;
    styles.height = node.absoluteBoundingBox.height;
  }
  
  // Background
  if (node.fills?.length) {
    const fill = node.fills.find(f => f.visible !== false && f.type === 'SOLID');
    if (fill?.color) {
      styles.backgroundColor = rgbaToHex(fill.color);
    }
  }
  
  // Border radius
  if (node.cornerRadius) {
    styles.borderRadius = node.cornerRadius;
  }
  
  // Padding
  if (node.paddingLeft) styles.paddingLeft = node.paddingLeft;
  if (node.paddingRight) styles.paddingRight = node.paddingRight;
  if (node.paddingTop) styles.paddingTop = node.paddingTop;
  if (node.paddingBottom) styles.paddingBottom = node.paddingBottom;
  
  // Flexbox (Auto Layout)
  if (node.layoutMode && node.layoutMode !== 'NONE') {
    styles.display = 'flex';
    styles.flexDirection = node.layoutMode === 'HORIZONTAL' ? 'row' : 'column';
    styles.gap = node.itemSpacing;
    
    // Alignment
    const alignMap: Record<string, string> = {
      'MIN': 'flex-start',
      'CENTER': 'center',
      'MAX': 'flex-end',
      'SPACE_BETWEEN': 'space-between',
    };
    if (node.primaryAxisAlignItems) {
      styles.justifyContent = alignMap[node.primaryAxisAlignItems] || 'flex-start';
    }
    if (node.counterAxisAlignItems) {
      styles.alignItems = alignMap[node.counterAxisAlignItems] || 'flex-start';
    }
  }
  
  return styles;
}

function generateJSX(node: FigmaNode): string {
  const styles = extractStyles(node);
  
  if (node.type === 'TEXT') {
    return `<span style={${JSON.stringify(styles)}}>${node.characters || ''}</span>`;
  }
  
  if (node.type === 'VECTOR' || node.type === 'BOOLEAN_OPERATION') {
    return `{/* Vector: ${node.name} - export as SVG */}`;
  }
  
  const children = node.children?.map(child => generateJSX(child)).join('\n') || '';
  return `<div style={${JSON.stringify(styles)}}>${children}</div>`;
}
```

### Generate Tailwind CSS from Figma
```typescript
function figmaToTailwind(node: FigmaNode): string {
  const classes: string[] = [];
  
  // Dimensions
  if (node.absoluteBoundingBox) {
    const { width, height } = node.absoluteBoundingBox;
    classes.push(`w-[${Math.round(width)}px]`, `h-[${Math.round(height)}px]`);
  }
  
  // Background color
  if (node.fills?.length) {
    const fill = node.fills.find(f => f.visible !== false && f.type === 'SOLID');
    if (fill?.color) {
      const hex = rgbaToHex(fill.color);
      classes.push(`bg-[${hex}]`);
    }
  }
  
  // Border radius
  if (node.cornerRadius) {
    const radiusMap: Record<number, string> = {
      4: 'rounded-sm', 6: 'rounded-md', 8: 'rounded-lg',
      12: 'rounded-xl', 16: 'rounded-2xl', 9999: 'rounded-full'
    };
    classes.push(radiusMap[node.cornerRadius] || `rounded-[${node.cornerRadius}px]`);
  }
  
  // Padding
  if (node.paddingLeft === node.paddingRight && 
      node.paddingTop === node.paddingBottom &&
      node.paddingLeft === node.paddingTop) {
    classes.push(`p-[${node.paddingLeft}px]`);
  } else {
    if (node.paddingLeft) classes.push(`pl-[${node.paddingLeft}px]`);
    if (node.paddingRight) classes.push(`pr-[${node.paddingRight}px]`);
    if (node.paddingTop) classes.push(`pt-[${node.paddingTop}px]`);
    if (node.paddingBottom) classes.push(`pb-[${node.paddingBottom}px]`);
  }
  
  // Flexbox
  if (node.layoutMode && node.layoutMode !== 'NONE') {
    classes.push('flex');
    classes.push(node.layoutMode === 'HORIZONTAL' ? 'flex-row' : 'flex-col');
    if (node.itemSpacing) classes.push(`gap-[${node.itemSpacing}px]`);
    
    const justifyMap: Record<string, string> = {
      'MIN': 'justify-start', 'CENTER': 'justify-center',
      'MAX': 'justify-end', 'SPACE_BETWEEN': 'justify-between'
    };
    const alignMap: Record<string, string> = {
      'MIN': 'items-start', 'CENTER': 'items-center', 'MAX': 'items-end'
    };
    if (node.primaryAxisAlignItems) classes.push(justifyMap[node.primaryAxisAlignItems]);
    if (node.counterAxisAlignItems) classes.push(alignMap[node.counterAxisAlignItems]);
  }
  
  return classes.join(' ');
}
```

### Extract All Components from File
```typescript
interface ComponentInfo {
  key: string;
  name: string;
  description: string;
  nodeId: string;
  thumbnailUrl?: string;
}

async function getAllComponents(fileKey: string): Promise<ComponentInfo[]> {
  const response = await fetch(
    `https://api.figma.com/v1/files/${fileKey}/components`,
    { headers: { 'X-Figma-Token': process.env.FIGMA_TOKEN! } }
  );
  const data = await response.json();
  
  return data.meta.components.map((comp: any) => ({
    key: comp.key,
    name: comp.name,
    description: comp.description || '',
    n
