基于vite6创建项目

pnpm create vue

vite已自动配置@路径，在.config.js  jsconfig.json 中

按需引用element-plus  官网中有

pnpm install element-plus

npm install -D unplugin-vue-components unplugin-auto-import

// vite.config.ts
import { defineConfig } from 'vite'
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'export default defineConfig({// ...plugins: [// ...AutoImport({resolvers: [ElementPlusResolver()],}),Components({resolvers: [ElementPlusResolver()],}),],
})

如果要自定义主题，方式如下

如果您的项目也使用了 SCSS，可以直接修改 Element Plus 的样式变量。 新建一个样式文件，例如 styles/element/index.scss：

pnpm i sass -D

index.css 代码定制

/* 只需要重写你需要的即可 */
@forward 'element-plus/theme-chalk/src/common/var.scss' with ($colors: ('primary': (// 主色'base': #27ba9b,),'success': (// 成功色'base': #1dc779,),'warning': (// 警告色'base': #ffb302,),'danger': (// 危险色'base': #e26237,),'error': (// 错误色'base': #cf4444,),)
)

样式重置common.scss

// 重置样式
* {box-sizing: border-box;
}html {height: 100%;font-size: 14px;
}
body {height: 100%;color: #333;min-width: 1240px;font: 1em/1.4 'Microsoft Yahei', 'PingFang SC', 'Avenir', 'Segoe UI','Hiragino Sans GB', 'STHeiti', 'Microsoft Sans Serif', 'WenQuanYi Micro Hei',sans-serif;
}

input[type='password'],
input[type='checkbox'] {padding: 0;outline: none;border: none;-webkit-appearance: none;&::placeholder {color: #ccc;}
}

}.fl {float: left;
}.fr {float: right;
}.clearfix:after {content: '.';display: block;visibility: hidden;height: 0;line-height: 0;clear: both;
}// reset element
.el-breadcrumb__inner.is-link {font-weight: 400 !important;
}

var.scss 定义变量

$xtxColor: #27ba9b;
$helpColor: #e26237;
$sucColor: #1dc779;
$warnColor: #ffb302;
$priceColor: #cf4444;

最后是config.js 文件指定配色相关，全代码都有注释

import { fileURLToPath, URL } from 'node:url'import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import vueDevTools from 'vite-plugin-vue-devtools'// element-plus 按需引入
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'// https://vite.dev/config/
export default defineConfig({plugins: [vue(),vueDevTools(),AutoImport({resolvers: [ElementPlusResolver()]}),Components({// 指定配色为sassresolvers: [ElementPlusResolver({ importStyle: 'sass' })]})],resolve: {alias: {// @ 实际转换为 src'@': fileURLToPath(new URL('./src', import.meta.url))}},css: {// 主题配色preprocessorOptions: {scss: {additionalData: `@use "@/styles/element/index.scss" as *;`}}},server: {port: 5600,open: true}
})

重启项目测试主题是否有用

pnpm i axios

封装它 代码要修改

// import loadingPlugin from "./plugins/loading/index.js";// 详细参考 todoproject ---web-coce 中
import axios from 'axios'
const TOKEN_KEY = '__TOKEN__'
const pendingMap = new Map()function getTokenAUTH() {return localStorage.getItem(TOKEN_KEY)
}/*** 生成唯一的每个请求的唯一key* @param {*} config* @returns*/
function getPendingKey(config) {let { url, method, params, data } = configif (typeof data === 'string') data = JSON.parse(data) // response里面返回的config.data是个字符串对象return [url, method, JSON.stringify(params), JSON.stringify(data)].join('&')
}/*** 储存每个请求的唯一cancel回调, 以此为标识* @param {*} config*/
function addPending(config) {const pendingKey = getPendingKey(config)config.cancelToken =config.cancelToken ||new axios.CancelToken((cancel) => {if (!pendingMap.has(pendingKey)) {pendingMap.set(pendingKey, cancel)}})
}/*** 删除重复的请求* @param {*} config*/
function removePending(config) {const pendingKey = getPendingKey(config)if (pendingMap.has(pendingKey)) {const cancelToken = pendingMap.get(pendingKey)cancelToken(pendingKey)pendingMap.delete(pendingKey)}
}/*** 关闭Loading层实例* @param {*} _options*/
function closeLoading(_options) {if (_options.loading && LoadingInstance._count > 0) LoadingInstance._count--if (LoadingInstance._count === 0) {if (LoadingInstance._target) {LoadingInstance._target.close()}LoadingInstance._target = null}
}const LoadingInstance = {_target: null,_count: 0
}// 添加loading
// const hideLoading = () => app.config.globalProperties.$smallLoading.hideLoading;
// const showLoading = () =>
//     app.config.globalProperties.$smallLoading.showLoading();
// let onProgress = () => app.config.globalProperties.$smallLoading.onProgress;export function __MyAxios__(axiosConfig, customOptions) {const service = axios.create({// baseURL: "", // 设置统一的请求前缀timeout: 30000, // 设置统一的超时时长responseType: 'json' // default})// 自定义配置let custom_options = {repeat_request_cancel: true, // 是否开启取消重复请求, 默认为 trueloading: false, // 是否开启loading层效果, 默认为falsereduct_data_format: true, // 是否开启简洁的数据结构响应, 默认为trueerror_message_show: true, // 是否开启接口错误信息展示,默认为truecode_message_show: false, // 是否开启code不为0时的信息提示, 默认为falsescroll_to_top: false, // 请求成功后滑动到页面顶部...customOptions}// 请求拦截service.interceptors.request.use((config) => {removePending(config)custom_options.repeat_request_cancel && addPending(config)// if (custom_options.loading) {//     LoadingInstance._count++;//     LoadingInstance._target = loadingPlugin();// }// 自动携带tokenif (getTokenAUTH() && typeof window !== 'undefined') {config.headers.Authorization = getTokenAUTH()}// 添加loading// showLoading();// config.onDownloadProgress = (progressEvent) => {//     let percentCompleted = Math.floor(//         (progressEvent.loaded * 100) / progressEvent?.total//     );//     onProgress()(percentCompleted);// };return config},(error) => {// hideLoading()();return Promise.reject(error)})// 响应拦截service.interceptors.response.use((response) => {removePending(response.config)if (custom_options.scroll_to_top) {window.scrollTo(0, 0)}closeLoading(custom_options)// loading// hideLoading()();return custom_options.reduct_data_format ? response.data : response},(error) => {if (custom_options.scroll_to_top) {window.scrollTo(0, 0)}error.config && removePending(error.config)closeLoading(custom_options)// loading// hideLoading()();// TODO:401const { status = 200 } = error.response || {}if (status === 401) {return window.location.replace('/login')}return Promise.reject(error) // 错误继续返回给到具体页面})return service(axiosConfig)
}

封装二 测试

//css

创建pinia 持久化存储

import { createPinia, defineStore } from 'pinia'
import piniaPluginPersistedstate from 'pinia-plugin-persistedstate'
import { ref } from 'vue'const pinia = createPinia()
pinia.use(piniaPluginPersistedstate)export const useStore = defineStore('store',() => {const profile = ref()const setProfile = (val) => {profile.value = valreturn profile.value}const clearProfile = () => {profile.value = undefined}return { setProfile, clearProfile, profile }},{persist: {
// 默认为true  自定义keykey: 'my--xtx-store'}}
)export default pinia

测试代码

import { useStore } from './stores'
const { setProfile, clearProfile } = useStore()
import { ref } from 'vue'const testProfile = ref('我是测试用户')const onSet = () => {setProfile(testProfile.value)console.log('🚀 ~ onSet ~ onSet:', testProfile.value)
}const onClear = () => {clearProfile()
}

vue-router

import { createRouter, createWebHistory } from 'vue-router'
import HomeView from '../views/HomeView.vue'import Home from '@/views/Home/index.vue'
import Layout from '@/views/Layout/index.vue'
import Login from '@/views/Login/index.vue'
import Category from '@/views/Category/index.vue'const router = createRouter({history: createWebHistory(import.meta.env.BASE_URL),routes: [{path: '/',name: 'layout',component: Layout,children: [{path: '',name: 'home',component: Home},{path: 'category',name: 'category',component: Category}]},{path: '/login',name: 'login',component: () => import('@/views/Login/index.vue')}]
})export default router

测试  在App.vue Layout.vue 中放入路由出口

<router-view />

切换不同路由  /category

导入main.js 中导入重置样式common.cscc

查看

index.html 

<link

rel="stylesheet"

href="//at.alicdn.com/t/font_2143783_iq6z4ey5vu.css"

/>

请求放在一起，目前请求还未封装完成  ToDo

吸顶效果

<script setup>
// 使用VueUse
import { useScroll } from '@vueuse/core'
const { y } = useScroll(window)
import { useHeaderStore } from '@/stores/Header.js'
const HeaderStore = useHeaderStore()
import HeaderCart from './HeaderCart.vue'
</script><template><div class="app-header-sticky" :class="{ show: y > 78 }"><div class="container"><RouterLink class="logo" to="/" /><!-- 导航区域 --><ul class="app-header-nav"><li class="home"><RouterLink to="/">首页</RouterLink></li><li class="home" v-for="item in HeaderStore.category" :key="item.key"><RouterLink :to="`/category/${item.id}`">{{ item.name }}</RouterLink></li></ul><div class="right"><RouterLink to="/">品牌</RouterLink><RouterLink to="/">专题</RouterLink></div><HeaderCart></HeaderCart></div></div>
</template><style scoped lang="scss">
.app-header-sticky {width: 100%;height: 80px;position: fixed;left: 0;top: 0;z-index: 999;background-color: #fff;border-bottom: 1px solid #e4e4e4;// 此处为关键样式!!!// 状态一：往上平移自身高度 + 完全透明transform: translateY(-100%);opacity: 0;// 状态二：移除平移 + 完全不透明&.show {transition: all 1s linear;transform: none;opacity: 1;}.container {display: flex;align-items: center;}.logo {width: 200px;height: 80px;background: url('@/assets/images/logo.png') no-repeat right 2px;background-size: 160px auto;}.right {width: 220px;display: flex;text-align: center;padding-left: 40px;border-left: 2px solid $xtxColor;a {width: 38px;margin-right: 40px;font-size: 16px;line-height: 1;&:hover {color: $xtxColor;}}}
}.app-header-nav {width: 820px;display: flex;padding-left: 40px;position: relative;z-index: 998;li {margin-right: 40px;width: 38px;text-align: center;a {font-size: 16px;line-height: 32px;height: 32px;display: inline-block;&:hover {color: $xtxColor;border-bottom: 1px solid $xtxColor;}}.active {color: $xtxColor;border-bottom: 1px solid $xtxColor;}}
}
</style>

之前方式对比 判断滚动距离监听是否添加class

head.js  调用一次就可以直接在其他组件使用其数据

import { ref } from 'vue'
import { defineStore } from 'pinia'
import {getCategoryAPI} from '@/api/user.js'
export const useHeaderStore = defineStore('Header', () => {const category = ref([])const getCategory= async ()=>{const res = await getCategoryAPI()// console.log(res.data.result);category.value = res.data.result
}return {category,getCategory }
})

图片懒加载  当图片进入视口区就开始加载

// 定义懒加载插件
import { useIntersectionObserver } from '@vueuse/core'
export const lazyPlugin = {install(app) {// 定义全局指令app.directive('img-lazy', {mounted(el, binding) {// el:绑定的元素// binding:指令的参数 binding-value:指令等于号后面绑定的表达式的值 图片url// console.log(el,binding.value);const { stop } = useIntersectionObserver(el, ([{ isIntersecting }]) => {// console.log(isIntersecting);if (isIntersecting) {// 图片懒加载el.src = binding.value// 成功加载后停止监听stop()}})}})}
}

激活模块

<RouterLink active-class="active" :to="`/category/${item.id}`">{{item.name}}</RouterLink>

列表无限加载

const disabled = ref(false)
const load = async () => {console.log('++++++++')reqDate.value.page++const res = await getSubCategoryAPI(reqDate.value)goodList.value = [...goodList.value, ...res.data.result.items]// 加载完毕 停止监听if (res.data.result.items.length === 0) {disabled.value = true}
}<divclass="body":infinite-scroll-disabled="disabled"v-infinite-scroll="load"style="overflow: auto"><GoodsItemv-for="item in goodList":key="item.id":good="item"></GoodsItem></div>
