Authorization check in vuejs?

Question

JSON Web Token

Hello, I wrote this code:

router.beforeEach((to, from, next) => {
  if (to.matched.some(record => record.meta.requiresAuth)) {
    if (Store.getters.isLoggedIn) {
      next()
      return
    }
    next({ name: 'Feed' })
  } else if (to.matched.some(record => record.meta.guest)) {
    if (localStorage.getItem('access_token') == null) {
      next()
    } else {
      next({ name: 'Feed' })
    }
  } else {
    next()
  }
})

The problem is that if I remove the access_token from localStorage.getItem, then it does not throw me on /login, but a white screen appears. I will be glad to any advice.
