export default {
  setup() {
    // tracks mouse position
    const { x, y } = useMouse()

    // is user prefers dark theme
    const isDark = usePreferredDark()

    // persist state in localStorage
    const store = useLocalStorage(
      'my-storage', 
      {
        name: 'Apple',
        color: 'red',
      },
    )
