How to access async store data in vue-router for usage in beforeEnter hook?

Question

How is it possible to access store data in beforeEnter which is retrieved asynchronously via the store action?

import store from \'./vuex/store\';

store.dis

I've solved this issue by using store.watch() for no initial value and return the latest value when already initialized.

Here is my sample code

async function redirectIfNotAuth (to, from, next) {
  const user = await getUserState()
  if (user === null) {
    next({ name: 'auth' })
  } else {
    next()
  }
}

function getUserState () {
  return new Promise((resolve, reject) => {
    if (store.state.user === undefined) {
      const unwatch = store.watch(
        () => store.state.user,
        (value) => {
          unwatch()
          resolve(value)
        }
      )
    } else {
      resolve(store.state.user)
    }
  })
}


/* STORE */
const store = new Vuex.Store({
  state: {
    user: undefined
  }
})

/* ROUTER */
new Router({
  routes: [
    {
      path: '',
      name: 'home',
      component: Home,
      beforeEnter: redirectIfNotAuth
    },
    {
      path: '/signin',
      name: 'auth',
      component: Auth,
    }
  ]
})
