long-running operations + +## Support + +For API issues or questions: +- Check logs: `capturecrafy.log` +- View database: `capturecrafy.db` +- Enable debug logging: `LOG_LEVEL=debug` diff --git

+

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

+

+ + 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;

+``` + +## 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;
