Vuejs tutorial add example for route guard

[jpmeijers]

Following the Vue Router docs on adding a route guard to prevent un-authenticated users from viewing any routes and get redirected to /login (https://router.vuejs.org/guide/advanced/navigation-guards.html#global-before-guards).

I tried the following index.js for the router component:

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'
import {useAuth0} from "@auth0/auth0-vue";

const routes = [
  {
    path: '/',
    name: 'home',
    component: HomeView
  },
  {
    path: '/login',
    name: 'login',
    component: () => import(/* webpackChunkName: "about" */ '../views/LoginView.vue')
  }
]

const router = createRouter({
  history: createWebHistory(process.env.BASE_URL),
  routes
})

router.beforeEach(async (to) => {
  const isAuthenticated = useAuth0().isAuthenticated;
  if (!isAuthenticated && to.name !== 'login') {
    return { name: 'login' }
  }
})

export default router

The problem is useAuth0() is undefined, also when I do const { isAuthenticated } = useAuth0();.

Please add an example how to correctly do this.
