How to access localStorage in store, namely state, using Nuxt.js?

Question

Vue.js

I am trying to access localStorage in store, namely state.
I understand that there is no access to browser methods/objects in SSR.
I'm trying to do this:

export const state = () => {
  if (process.client) {
    return {
      isAuth: localStorage.getItem('isAuth')
    }
  }
}

The development console (Vuex) is empty, there is nothing.
And if so:

export const state = () => {
  if (process.client) {
    return {
      isAuth: localStorage.getItem('isAuth')
    }
  } else {
    return {
      isAuth: 'SomeData'
    }
  }
}

Then he sees server work and isAuth = 'SomeData'

How to get access to localStorage?

Answer 1

I solved this problem in the following way:
In the layout/default where the Nuxt component is located, in the mounted hook I do the dispatch:

setLocalStorage(state) {
    state.isAuth = localStorage.getItem('isAuth')
  },

If you know a better solution, I'd love to hear it.
