Figma API Integration

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

Quick Start

Authentication

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

// 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

  }
}

Component Code Generation

Figma Node to React Component

interface FigmaNode {
  id: string;
  name: string;

  characters?: string;
  style?: TextStyle;
}

async function getComponentCode(fileKey: string, nodeId: string): Promise<string> {

    `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);
