Use in Components + +```typescript +// components/FileViewer.tsx +import { useState, useEffect } from 'react'; +import { figmaClient } from '@/lib/figma-api'; + +export function FileViewer({ fileKey }: { fileKey: string }) { + const [file, setFile] = useState(null); + const [loading, setLoading] = useState(true); + const [error, setError] = useState(null); + + useEffect(() => { + const fetchFile = async () => { + try { + setLoading(true); + const response = await figmaClient.getFile(fileKey); + setFile(response.data.file); + } catch (err) { + setError(err.message); + } finally { + setLoading(false); + } + }; + + fetchFile(); + }, [fileKey]); + + if (loading) return

Loading...
; + if (error) return
Error: {error.message}
; + + return
{data.data.file.name}
; +} +``` + +## OAuth Flow + +### Step 1: Initiate OAuth + +```typescript +function initiateOAuth() { + const clientId = process.env.REACT_APP_FIGMA_CLIENT_ID; + const redirectUri = `${window.location.origin}/auth/callback`; + const scope = 'files:read,webhooks:write'; + const state = generateRandomString(32); + + // Store state for verification + localStorage.setItem('oauth_state', state); + + const authUrl = new URL('https://www.figma.com/oauth'); + authUrl.searchParams.append('client_id', clientId); + authUrl.searchParams.append('redirect_uri', redirectUri); + authUrl.searchParams.append('scope', scope); + authUrl.searchParams.append('state', state); + authUrl.searchParams.append('response_type', 'code'); + + window.location.href = authUrl.toString(); +} +``` + +### Step 2: Handle Callback + +```typescript +// pages/auth/callback.tsx +import { useEffect, useRef } from 'react'; +import { useNavigate, useSearchParams } from 'react-router-dom'; + +export function AuthCallback() { + const navigate = useNavigate(); + const [searchParams] = useSearchParams(); + const processingRef = useRef(false); + + useEffect(() => { + if (processingRef.current) return; + processingRef.current = true; + + const processCallback = async () => { + const code = searchParams.get('code'); + const state = searchParams.get('state'); + + // Verify state + const savedState = localStorage.getItem('oauth_state'); + if (state !== savedState) { + throw new Error('State mismatch - possible CSRF attack'); + } + localStorage.removeItem('oauth_state'); + + // Exchange code for token + const response = await fetch('/api/auth/token', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ + code, + clientId: process.env.REACT_APP_FIGMA_CLIENT_ID, + clientSecret: process.env.REACT_APP_FIGMA_CLIENT_SECRET, + }), + }); + + const { token } = await response.json(); + + // Store token + localStorage.setItem('figma_token', token); + figmaClient.setApiKey(token); + + // Redirect to dashboard + navigate('/dashboard'); + }; + + processCallback(); + }, [searchParams, navigate]); + + return
Authenticating...
; +} +``` + +### Step 3: Store & Refresh Token + +```typescript +// lib/token-manager.ts +export class TokenManager { + private tokenKey = 'figma_token'; + private refreshKey = 'figma_refresh_token'; + + setToken(token: string, refreshToken?: string) { + localStorage.setItem(this.tokenKey, token); + if (refreshToken) { + localStorage.setItem(this.refreshKey, refreshToken); + } + } + + getToken() { + return localStorage.getItem(this.tokenKey); + } + + async refreshToken() { + const refreshToken = localStorage.getItem(this.refreshKey); + if (!refreshToken) throw new Error('No refresh token'); + + const response = await fetch('/api/auth/refresh', { + method: 'POST', + headers: { 'Content-Type': 'application/json' }, + body: JSON.stringify({ refreshToken }), + }); + + const { token } = await response.json(); + this.setToken(token); + return token; + } + + logout() { + localStorage.removeItem(this.tokenKey); + localStorage.removeItem(this.refreshKey); + } +} + +export const tokenManager = new TokenManager(); +``` + +## Common Use Cases + +### Use Case 1: Display Figma File Preview + +```typescript +export function FilePreviewCard({ fileKey }: { fileKey: string }) { + const { data: file } = useFile(fileKey); + + return ( +
+

{file?.data?.file?.name}

+

{file?.data?.file?.lastModified}

+ + Open in Figma + +
+ ); +} +``` + +### Use Case 2: List Components + +```typescript +export function ComponentLibrary({ fileKey }: { fileKey: string }) { + const [components, setComponents] = useState([]); + + useEffect(() => { + figmaClient.getFileComponents(fileKey).then((res) => { + setComponents(res.data.components); + }); + }, [fileKey]); + + return ( +
+ {components.map((component) => ( +
+ {component.name} +

{component.name}

+
+ ))} +
+ ); +} +``` + +### Use Case 3: Export Designs + +```typescript +export function ExportButton({ fileKey, nodeId }: { fileKey: string; nodeId: string }) { + const [loading, setLoading] = useState(false); + const [url, setUrl] = useState(null); + + const handleExport = async () => { + setLoading(true); + try { + const response = await figmaClient.exportNode(fileKey, nodeId, 'PNG'); + setUrl(response.data.url); + } finally { + setLoading(false); + } + }; + + return ( +
+ + {url && ( + + Download + + )} +
+ ); +} +``` + +### Use Case 4: Search Components + +```typescript +export function ComponentSearch() { + const [query, setQuery] = useState(''); + const [results, setResults] = useState([]); + + const handleSearch = async (e: React.FormEvent) => { + e.preventDefault(); + const response = await figmaClient.searchComponents(query); + setResults(response.data.components); + }; + + return ( +
+ setQuery(e.target.value)} + placeholder="Search components..." + /> + + +
    + {results.map((component) => ( +
  • {component.name}
    • + ))} +
+
+ ); +} +``` + +### Use Case 5: Sync Updates + +```typescript +export function FileSyncStatus() { + const [status, setStatus] = useState(null); + + useEffect(() => { + // Poll every 10 seconds + const interval = setInterval(async () => { + const response = await fetch('/api/sync/status', { + headers: { + Authorization: `Bearer ${localStorage.getItem('figma_token')}`, + }, + }); + const data = await response.json(); + setStatus(data.data); + }, 10000); + + return () => clearInterval(interval); + }, []); + + return ( +
+

Last sync: {status?.lastSync}

+

Pending events: {status?.pendingEvents}

+

Status: {status?.status}

+
+ ); +} +``` + +## Error Handling + +### Error Types + +```typescript +enum ErrorCode { + UNAUTHORIZED = 'UNAUTHORIZED', + RATE_LIMIT = 'RATE_LIMIT_EXCEEDED', + NOT_FOUND = 'NOT_FOUND', + VALIDATION_ERROR = 'VALIDATION_ERROR', + SERVER_ERROR = 'SERVER_ERROR', +} + +interface APIError { + code: ErrorCode; + message: string; + statusCode: number; + retryAfter?: number; +} +``` + +### Retry Logic + +```typescript +export async function retryWithBackoff( + fn: () => Promise, + maxRetries = 3, + initialDelay = 1000, +): Promise { + let lastError: Error;

+``` + +## Testing Integration + +### Unit Tests + +```typescript +// __tests__/figma-api.test.ts +import { FigmaAPIClient } from '@/lib/figma-api'; +import { vi } from 'vitest'; + +describe('FigmaAPIClient', () => { + let client: FigmaAPIClient;
