vue实际运用之vuex持久化详解

import Vue from 'vue'
import Vuex from 'vuex'
//引入
import persistedState from 'vuex-persistedstate'
Vue.use(Vuex)
export default new Vuex.Store({
  state: {
    num: null,
    name: null
  },
  mutations: {
    getNum(state, val) {
      state.num = val
    },
    getName(state, val) {
      state.name = val
    }
  },
  //配置
  plugins: [
    persistedState({
    	//默认使用localStorage来固化数据，也可使用sessionStorage，配置一样
      storage: window.localStorage,
      reducer(val) {
        return {
        // 只储存state中的值
          num: val.num,
          name: val.name
        }
      }
    })
  ]
})

created(){
    this.$store.commit('getNum',3)
    this.$store.commit('getName','胡歌')
  },

<template>
  <div>
      {{$store.state.num}}
      {{$store.state.name}}
  </div>
