UPD
app.js

import Vue from 'vue'
import store from './store/store.js'
import mapState from 'vuex'

new Vue({
    computed: {
        ...mapState({
            userStore: state => state.userStore
        })
    }
});

store.js

import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex);

const state = {
    alo: false
}

const mutations = {
    change_bool (state, value) {
        state.alo = value;
    }
}

const action = {
    changeState: ({commit}, value) => {
        commit('change_bool', value);
    }
}

export default {
    state, mutations, action
}
