vuex如何實現數據持久化，刷新頁面存儲的值還存在

1.安裝:

npm install vuex-persistedstate  --save

2.找到store/index.js

import Vue from 'vue'
import Vuex from 'vuex'
import VuexPersistense from 'vuex-persistedstate'
Vue.use(vuex)

import app from './modules/app'
import getters from './getters'

const vuexLocal = new VuexPersistense({
  storage: localStorage,
  reducer: val => {
    return {
      //引入app模板，對象里面可配置需要持久化的status
      app: {
        sidebar: val.app.sidebar,
        device: val.app.device
      }
    }
  }
})

const store = new Vuex.Store({
  modules: {
    app    
  },
  getters,
  plugins: [vuexLocal]
})

export default store
