Vuex persistence

Vuex: refresh the browser, and the state in vuex will return to its original state

Solution:

Use the vuex-persistedstate plug-in (which is actually automatically stored in local storage)

Install npm I-S vuex-persistedstate

Introduction and configuration: in index.js under store

Import Vue from 'vue'import Vuex from' vuex'// introduces 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}} / / configure plugins: [persistedState ({/ / localStorage is used by default to solidify data You can also use sessionStorage to configure the same storage: window.localStorage, reducer (val) {return {/ / only store the values in state num: val.num, name: val.name}})]}))

I assign values to variables in state in vuex in the Home component

Created () {this.$store.commit ('getNum',3) this.$store.commit (' getName',' Hu GE')}

Reference in the H component

{{$store.state.num}} {{$store.state.name}}

If you refresh the H component in this way, the variables in $store.state will not change. In fact, they will automatically be stored in the local storage.
