  exportToPDF,
  importFromJSON 
} from './utils/exportHelpers'

// Export diagram
exportToJSON(diagramData, 'my-diagram')
exportToPNG(elementRef.current, 'my-diagram')

// Import diagram
const data = await importFromJSON()

State Access

import useStore from './store/useStore'

function MyComponent() {
  const { 
    activeCanvas, 
    setActiveCanvas,
    theme,
    toggleTheme 
  } = useStore()
