Using localStorage in Vue. Where do I need to use it?

Question

I want to use localStorage so that the data is saved when the page reloads.

I use Vuex to track whether a person is registered. And hopefully when the page loads, the person is already registered.

My Vuex code is as follows:

export default {
    state:{
        isRegistered:false
    },
    actions:{
        registrate({commit}) {
            commit("login")
        },
        exit({commit}) {
            commit("logout")
        }
    },
    mutations:{
        login(state) {
            state.isRegistered=true;
        },
        logout(state) {
            state.isRegistered=false
        }
    },
    getters:{
        IS_REGISTERED(state){
            return state.isRegistered
        }
    }
}

Links in my Vue.js

<template>
    <header class="hat">
        <div class="header__buttons">
          
    
            <div v-if="IS_REGISTERED" id="exit--tittle">
                <button @click="exitFromSystem">Exit from system</button>
            </div>
    
            <router-link :to="{name:'registration'}">
                <button id="registration" v-if="!IS_REGISTERED">Registration</button>
            </router-link>
        </div>
    </header>
</template>


<script>
    methods: {
        ...mapActions(["exit"]),
        exitFromSystem() {
            this.exit() // Look in Vuex
        },
    },
</script>

 Where is the best place to use localStorage to save IS_REGISTERED when reloading the page?

Translation: I solved this problem myself, // npm-> npm install vuex-persistedstate // OR // yarn-> yarn add vuex-persistedstate

In my store, required Add it like this:

import Vue from "vue"
import Vuex from "vuex"
import createPersistedState from "vuex-persistedstate";

export default new Vuex.Store({
   modules:{
       // 
   },
   plugins:[createPersistedState()]
}
