/**
* Global state is injected by {@link import('~/plugins/state') state} plugin into our nuxt app (available as `$state`).
* You can still call `useGlobal` to receive the `$state` object and access the global state.
* If it's not available yet, a new global state object is created and injected into the nuxt app.
*
* Part of the state is stored in {@link WindowLocalStorage localStorage}, so it will be available even if the user closes the browser tab.
* Check the {@link StoredState StoredState} type for more information.
*
* @example
* ```js
* import { useNuxtApp } from '#app'
*
* const { $state } = useNuxtApp()
*
* const token = $state.token.value
* const user = $state.user.value
* ```
*
* @example
* ```js
* import { useGlobal } from '#imports'
*
* const globalState = useGlobal()
*
* cont token = globalState.token.value
* const user = globalState.user.value
*
* console.log(state.isLoading.value) // isLoading = true if any api request is still running
* ```
