vite项目 router使用 pinia使用

router使用

安装

yarn add vue-router || yarn i vue-router


在src内部创建 router文件夹（router.js, index.js）

main.js:

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import { createPinia } from 'pinia'
import router from './router'
createApp(App).use(router).mount('#app')

router.js:

const login = import(/* webpackChunkName: "loginjs" */"../views/login.vue")
let routes = [
    { path: "/", component: login },
    {
        path:'/home',
        name:'home',
        component:()=>import('../views/home.vue')
    }
    
]
export default routes

index.js:

import routes from './router'
//createWebHistory路由模式路径不带#号：
//createWebHashHistory路由模式路径带#号：
import { createRouter, createWebHistory } from "vue-router";
const router = createRouter({
    history:createWebHistory(),
    routes
})
export default router

app.vue

<div>
  <router-view></router-view>
</div>

常用 跳转方法

//标签
<router-link to="login"> 去登陆</router-link>
//js
import { useRoute, useRouter } from 'vue-router';
const route = useRoute()
const router = useRouter()
//不传参
router.push('/login')
//传参
router.push({path:'/login',query:{id:1,type:2}})
//接受参数 route.query.xxx
alert('id === '+route.query.id)

pinia使用

安装

yarn add pinia

和

yarn add pinia-plugin-persist


yarn add pinia-plugin-persist 数据持久化插件

main.js:

import { createPinia } from 'pinia'
import piniaPersist from 'pinia-plugin-persist'
const pinia = createPinia()
pinia.use(piniaPersist)
createApp(App).use(router).use(pinia).mount('#app')

tsconfig.json 在

compilerOptions

对象里加

"types": ["pinia-plugin-persist-uni"]


新建store文件夹 建index.js

import { defineStore } from 'pinia'
import Cookies from 'js-cookie'//如果需要存到cookie里面的话 需要 npm i js-cookie|| yarn add js-cookie

//存cookie方法
const cookiesStorage = {
    setItem (key, state) {
        return Cookies.set('info', state, { expires: 3 });
    },
    getItem (key) {
        return Cookies.get('info')
    },
  }
// 定义并导出容器，第一个参数是容器id，必须唯一，用来将所有的容器
// 挂载到根容器上
export const userInfo = defineStore('user', {
    // 定义state，用来存储状态的
    state: () => {
        return {
            info: {
                token: '',
                userName: '',
                userId: ''
            },
        }
    },
//使用yarn add pinia-plugin-persist需要以下
    persist: {
        enabled: true, //开启存储
        // storage:sessionStorage/localStorage,还可以自定义存入对应的如下
        //不写以下也可以 默认是sessionStorage
        strategies: [
            { storage: cookiesStorage, paths: ['info'] }
            //{ storage: localStorage, paths: ['info'] }
            //{ storage: sessionStorage, paths: ['info'] }
        ],
    },
    // 定义getters，类似于computed，具有缓存g功能
    getters: {},
    // 定义actions，类似于methods，用来修改state，做一些业务逻辑
    actions: {}
})

存取数据

// 任意页面
import { userInfo } from '../store/index.js'

//存
import { ref, reactive, toRefs } from "vue";
let info = reactive({
  token: "xxx123xxx456xxx789",
  userId: "168",
  userName: "张三",
});
useuserInfo.info = info
//取
console.log(useuserInfo.info)
