安装

yarn add pinia-plugin-persistedstate
or
npm i  pinia-plugin-persistedstate

使用插件 在main.ts中注册

import { createApp } from "vue";
import App from "./App.vue";
import piniaPluginPersistedstate from 'pinia-plugin-persistedstate'

const pinia = createPinia();
pinia.use(piniaPluginPersistedstate);
createApp(App).use(pinia);

路由代码

// import {createRouter, createWebHistory, createWebHashHistory} from "vue-router";

// // 1. 配置路由
// const routes: ({ redirect: string; path: string } | { path: string; component: () => Promise<any> } | { path: string; component: () => Promise<any>; children: ({ path: string; components: { son2: () => Promise<any> } } | { path: string; components: { son3: () => Promise<any> } })[] } | { path: string; components: { son1: () => Promise<any> }; name: string; props: { son1: boolean } })[] = [
//     {path: '/', redirect: '/login'},
//     {path: '/login', component: () => import('../views/login.vue')},
//     {
//         path: '/home',
//         component: () => import('../views/home/home.vue'),

//         props: { son1: true }
//     }
//
// ];
// // 2.返回一个 router 实列，为函数，配置 history 模式
// const router = createRouter({
//     history: createWebHashHistory(),
//     routes,
// });
//
//
// // 3.导出路由   去 main.ts 注册 router.ts
//
// export default router

import { createRouter, createWebHistory } from 'vue-router'

const router = createRouter({
    history: createWebHistory(),
    routes: [
            {path: '/', redirect: '/login'},

export default router

我把代码放git上了，有需要的自行拉取
