vite+naiveui+vue3+pinia+vue-router搭建简单后台管理系统 - vite - 前端 - 技术设计

构建工具使用 vue3 推荐的 vite；
状态管理使用 pinia，该库的作者也是 vuex 的核心成员；
UI 组件库使用尤大推荐的 naiveui。欢迎各位大神指导。话不多说，直接开撸。

# 一、初始化 vite 模板

国内使用最好将 yarn 切换到淘宝源：

	yarn config set registry https://registry.npmmirror.com/

	yarn create @vitejs/app

之后会让你输入项目名称，选择框架等。这里我们输入名称为 jianshu，框架选择 vue，回车
然后进入项目中，输入 yarn 回车，安装依赖

cd jianshu && yarn

安装完成之后，使用 yarn dev 命令启动开发服务。
打开 localhost:3000 地址，可以看到 vite 默认的欢迎页面。

# 二、安装插件

axios：网络请求；
sass：css 预处理；
js-md5：登录密码使用 md5 加密，如果不需要则可以不用安装；
pinia：状态管理；
moment：时间格式化；
naive-ui：UI 组件库；
vfonts：naiveui 的字体库；
@vicons/antd：图标库，可自行选择；
vue-router：路由；
unplugin-auto-import：自动导入 composition api；
unplugin-vue-components：自动注册组件；

yarn add axios sass js-md5 pinia moment naive-ui vfonts @vicons/antd vue-router unplugin-auto-import unplugin-vue-components

全部安装完成后，删除 components 下默认的页面和 assets 下的 logo.png，然后进行项目的配置

# 三、项目配置

# 1. unplugin-auto-import，unplugin-vue-components，naive-ui：

打开 vite.config.js 文件，引入组件

	import AutoImport from 'unplugin-auto-import/vite';
	import Components from 'unplugin-vue-components/vite';
	import { NaiveUiResolver } from 'unplugin-vue-components/resolvers';

然后在 plugins 内添加配置

	export default defineConfig({
	plugins: [
	vue(),
	AutoImport({
	imports: ['vue']
	}),
	Components({
	resolvers: [NaiveUiResolver()]
	})
	]
	});

这里 naiveui 使用的是按需自动引入，具体可参考官方文档：按需引入（Tree Shaking） - Naive UI 添加了一些打包的配置，不需要可以忽略。配置完成后的样子：

	import { defineConfig } from 'vite';
	import vue from '@vitejs/plugin-vue';
	import AutoImport from 'unplugin-auto-import/vite';
	import Components from 'unplugin-vue-components/vite';
	import { NaiveUiResolver } from 'unplugin-vue-components/resolvers';

	// 获取当前时间戳
	const timeStamp = new Date().getTime();

	export default defineConfig({
	plugins: [
	vue(),
	AutoImport({
	imports: ['vue']
	}),
	Components({
	resolvers: [NaiveUiResolver()]
	})
	],
	// 自定义端口号，默认为 3000
	server: {
	port: 3001
	},
	// 打包配置
	build: {
	// 文件夹名称
	outDir: 'dist',
	// 去掉 console 语句
	terserOptions: {
	compress: {
	drop_console: true
	}
	},
	compress: {
	drop_console: true,
	drop_debugger: true
	},
	// 文件名
	rollupOptions: {
	output: {
	entryFileNames: `assets/[name].${timeStamp}.js`,
	chunkFileNames: `assets/[name].${timeStamp}.js`,
	assetFileNames: `assets/[name].${timeStamp}.[ext]`
	}
	}
	}
	});

# 2. 配置 pinia：

在 src 目录下新建 plugins 文件夹，然后新建 pinia.js：

	import { createPinia } from 'pinia';

	const pinia = createPinia();

	export default pinia;

到 src 目录下新建 store 目录，然后新建 user.js：

	import { defineStore } from 'pinia';

	export const useUserStore = defineStore('user', {
	state: () => ({
	userInfo: JSON.parse(localStorage.getItem('userInfo')),
	token: localStorage.getItem('token')
	}),
	actions: {
	LoginIn(data) {
	this.token = data.token;
	this.userInfo = data;
	localStorage.setItem('userInfo', JSON.stringify(data));
	localStorage.setItem('token', data.token);
	localStorage.setItem('expire', data.expire);
	},
	LoginOut() {
	localStorage.removeItem('userInfo');
	localStorage.removeItem('token');
	localStorage.removeItem('expire');
	location.href = '/';
	}
	}
	});

user.js 里面添加了一些基本的用户信息和登录操作
pinia 和 vuex 的用法不一样，具体可以参考官方文档：Home | Pinia

# 3. 配置 axios：

在 plugins 下新建 axios.js 文件：

	import axios from 'axios';
	import pinia from './pinia';
	import { useUserStore } from '../store/user';

	const user = useUserStore(pinia);

	// api
	const apiHost = ''; // 接口地址

	let http = axios.create({
	// 当前环境为线上时，自动使用 production 环境变量里的 VITE_API_BASEURL 线上接口地址
	baseURL: import.meta.env.MODE === 'production' ? import.meta.env.VITE_API_BASEURL : apiHost,
	timeout: 60000,
	headers: {
	'Content-Type': 'application/json;charset=UTF-8;'
	}
	});

	// 参数配置
	let needLoading = true, // 是否需要 loading
	needErrorNotify = true, // 是否需要错误提示
	requestCount = 0; // 请求数量，用于 loading 控制，避免多个接口并发时重复 loading

	//loading 操作
	const ShowLoading = () => {
	if (requestCount === 0) {
	$uiMsg.loading('加载中');
	}
	requestCount++;
	};
	const HideLoading = () => {
	requestCount--;
	if (requestCount <= 0) {
	requestCount = 0;
	$uiMsg.removeMessage();
	}
	};

	http.interceptors.request.use(config => {
	// 切换组件时，取消还未完成的请求
	config.cancelToken = new axios.CancelToken(cancel => {
	window.__axiosPromiseArr.push({
	url: config.url,
	cancel
	});
	});
	needLoading && ShowLoading();
	if (user.token) {
	config.headers.Authorization = 'Bearer ' + user.token;
	}
	return config;
	});
	http.interceptors.response.use(
	response => {
	if (needLoading) {
	HideLoading();
	}
	// 换 token 时报错，退出登录
	if (response.config.url.indexOf('/token') !== -1 && response.data.code !== 200) {
	HideLoading();
	$uiMsg.error('登录已过期，请重新登录', () => {
	user.LoginOut();
	});
	return;
	}
	return response.data;
	},
	error => {
	HideLoading();
	if (error.response && error.response.status === 401) {
	//token 过期访问刷新 token 的接口
	return http
	.post('/token', JSON.stringify(user.token))
	.then(res => {
	if (res.code !== 200) {
	$uiMsg.error(res.msg);
	return;
	}
	// 更新 pinia 里的数据
	user.LoginIn(res.body);
	// 刷新 token 后重新请求之前的接口
	const config = error.response.config;
	config.headers.Authorization = 'Bearer ' + res.body.token;
	return http(config);
	})
	.catch(error => {
	$uiMsg.error(error.msg);
	});
	} else {
	$uiMsg.error('网络错误，请稍后再试');
	return Promise.reject(error);
	}
	}
	);

	const get = (url, params, _needLoading = true, _needErrorNotify = true) => {
	needLoading = _needLoading;
	needErrorNotify = _needErrorNotify;
	return new Promise((resolve, reject) => {
	let _timestamp = new Date().getTime();
	http
	.get(url, { params })
	.then(res => {
	if (new Date().getTime() - _timestamp < 200) {
	setTimeout(() => {
	if (res?.code === 200) {
	resolve(res);
	} else {
	needErrorNotify && res && res.msg && $uiMsg.error(res.msg);
	reject(res);
	}
	}, 200);
	} else {
	if (res?.code === 200) {
	resolve(res);
	} else {
	needErrorNotify && res && res.msg && $uiMsg.error(res.msg);
	reject(res);
	}
	}
	})
	.catch(error => {
	reject(error);
	});
	});
	};

	const post = (url, params, _needLoading = true, _needErrorNotify = true) => {
	needLoading = _needLoading;
	needErrorNotify = _needErrorNotify;
	return new Promise((resolve, reject) => {
	let _timestamp = new Date().getTime();
	http
	.post(url, params)
	.then(res => {
	if (new Date().getTime() - _timestamp < 200) {
	setTimeout(() => {
	if (res?.code === 200) {
	resolve(res);
	} else {
	needErrorNotify && res && res.msg && $uiMsg.error(res.msg);
	reject(res);
	}
	}, 200);
	} else {
	if (res?.code === 200) {
	resolve(res);
	} else {
	needErrorNotify && res && res.msg && $uiMsg.error(res.msg);
	reject(res);
	}
	}
	})
	.catch(error => {
	reject(error);
	});
	});
	};

	export { get, post };

这里使用了环境变量来自动选择 api 接口地址，在 src 同级目录下新建.env.production 文件：

	NODE_ENV = production

	# 线上接口请求地址
	VITE_API_BASEURL = ''

项目打包后会自动使用 production 环境变量里的 VITE_API_BASEURL

# 3. 配置 vue-router：

在 plugins 下新建 router.js：

	import { createRouter, createWebHistory } from 'vue-router';
	import pinia from './pinia';
	import { useUserStore } from '../store/user';

	const user = useUserStore(pinia);

	// 不需要权限的页面
	const constantRoutes = [
	{
	// 登录
	path: '/login',
	name: 'login',
	component: () => import('../views/login/index.vue')
	},
	{
	// 404
	path: '/:pathMatch(.*)',
	name: 'notFound',
	component: () => import('../views/error/notFound.vue')
	},
	{
	// 无权限
	path: '/noPermission',
	name: 'noPermission',
	component: () => import('../views/error/noPermission.vue')
	}
	];

	const asyncRoutes = {
	path: '/',
	name: 'main',
	component: () => import('../views/mainPage.vue'),
	children: [
	{
	// 首页
	path: '/',
	name: 'home',
	component: () => import('../views/home/index.vue')
	},
	{
	// 用户管理
	path: '/settingUser',
	name: 'settingUser',
	component: () => import('../views/setting/user.vue')
	}
	]
	};

	const router = createRouter({
	history: createWebHistory('/'),
	routes: constantRoutes
	});

	router.addRoute(asyncRoutes);

	router.beforeEach((to, from, next) => {
	// 切换 router 时，取消 pending 中的请求
	if (window.__axiosPromiseArr) {
	window.__axiosPromiseArr.forEach((ele, ind) => {
	ele.cancel();
	delete window.__axiosPromiseArr[ind];
	});
	}
	//token 过期
	if (localStorage.getItem('expires') && (new Date().getTime() - localStorage.getItem('expires')) / 1000 > 1) {
	$uiMsg.error('登录失效，请重新登录', () => {
	localStorage.removeItem('userInfon');
	localStorage.removeItem('token');
	localStorage.removeItem('expires');
	location.href = '/login';
	});
	return;
	}
	// 登录判断
	if (user.token) {
	if (to.path === '/login') {
	next({ path: '/' });
	} else {
	// 权限判断
	next();
	}
	} else {
	if (to.path === '/login') {
	next();
	} else {
	next({ name: 'login' });
	}
	}
	});

	// 跳转完成后，将滚动条位置重置
	router.afterEach(to => {
	window.scrollTo(0, 0);
	});

	export default router;

router 中引入了一些默认页面，我们来创建一些简单的页面组件：

/src/views/error/notFound.vue

	<div class="not-found">

	export default {

	methods: {
	GoHome() {
	this.$router.replace('/');
	}
	}
	}

/src/views/mainPage.vue

	<template>
	<n-layout has-sider>
	<n-layout-sider class="ui-menu" width="200">
	<Menu />
	</n-layout-sider>
	<n-layout>
	<n-layout-header class="ui-header">
	<Header />
	</n-layout-header>
	<n-layout-content class="ui-main">
	<router-view></router-view>
	</n-layout-content>
	</n-layout>
	</n-layout>
	</template>

	<script setup>
	import Header from '../components/layout/Header.vue';
	import Menu from '../components/layout/Menu.vue';
	</script>

	<style lang="scss" scoped>
	.ui-menu {
	min-height: 100vh;
	background-color: #001428;
	color: #fff;
	}
	.ui-header {
	height: 50px;
	border-bottom: 1px solid #ddd;
	}
	.main-page-box {
	height: calc(100vh - 50px);
	overflow: auto;
	}
	.ui-main{
	padding: 10px;
	}
	</style>

mainPage 中引入了两个组件，下面公共组件的时候会讲到。
/src/views/home/index.vue

	<template> 我是首页 </template>

	<script setup></script>

	<style lang="scss" scoped></style>
	/src/views/login/index.vue
	<template>
	<n-button @click="Login">我要登录</n-button>
	</template>

	<script setup>
	import { useUserStore } from '../../store/user';
	const user = useUserStore();

	const Login = () => {
	user.LoginIn({
	expire: 3600,
	loginName: 'admin',
	staffId: 1,
	token: 'test',
	trueName: '管理员'
	});
	$uiMsg.success('登录成功', async () => {
	$router.push('/');
	});
	};
	</script>

可以看到 axios 和 router 中都使用了 pinia，需要注意的是，这里不能像组件中直接引入，需要将 pinia 单独配置成一个 js，然后使用的时候引入。

组件中的写法：

	import { useUserStore } from '../store/user';

	const user = useUserStore();

axios 和 router 中的写法：

	import pinia from './pinia';
	import { useUserStore } from '../store/user';

	const user = useUserStore(pinia);

# 4. main.js 配置

引入我们刚刚配置好的插件，挂载全局变量。打开 main.js ：

	import { createApp } from 'vue';
	import App from './App.vue';
	import './style/index.css';
	import { uiCopy, uiDownloadImg } from './utils';
	import { get, post } from './plugins/axios';
	import moment from 'moment';
	import pinia from './plugins/pinia';
	import router from './plugins/router';

	const app = createApp(App);

	app.use(pinia);
	app.use(router);

	if (import.meta.env.MODE === 'production') {
	app.config.devtools = false;
	} else {
	app.config.devtools = true;
	}

	// 请求队列
	window.__axiosPromiseArr = [];

	// 挂载全局变量
	app.config.globalProperties.$get = get;
	app.config.globalProperties.$post = post;
	app.config.globalProperties.$moment = moment;
	app.config.globalProperties.$uiCopy = uiCopy;
	app.config.globalProperties.$uiDownloadImg = uiDownloadImg;

	app.mount('#app');
	./style/index.css`是使用了reset.css重置了浏览器的默认样式 `index.css
	html, body, div, span, applet, object, iframe,
	h1, h2, h3, h4, h5, h6, p, blockquote, pre,
	a, abbr, acronym, address, big, cite, code,
	del, dfn, em, img, ins, kbd, q, s, samp,
	small, strike, strong, sub, sup, tt, var,
	b, u, i, center,
	dl, dt, dd, ol, ul, li,
	fieldset, form, label, legend,
	table, caption, tbody, tfoot, thead, tr, th, td,
	article, aside, canvas, details, embed,
	figure, figcaption, footer, header, hgroup,
	menu, nav, output, ruby, section, summary,
	time, mark, audio, video {
	margin: 0;
	padding: 0;
	border: 0;
	font-size: 100%;
	font: inherit;
	}
	/* HTML5 display-role reset for older browsers */
	article, aside, details, figcaption, figure,
	footer, header, hgroup, menu, nav, section {
	display: block;
	}
	body {
	line-height: 1;
	}
	ol, ul {
	list-style: none;
	}
	blockquote, q {
	quotes: none;
	}
	blockquote:before, blockquote:after,
	q:before, q:after {
	content: '';
	content: none;
	}
	table {
	border-collapse: collapse;
	border-spacing: 0;
	}

utils 内是常用的一些工具函数，具体可以看下面。不需要则可以忽略

# 5. 其他配置

# Utils

src 目录下新建 utils 文件夹，创建 index.js

	// 公共复制剪贴板
	const uiCopy = str => {
	let copyDom = document.createElement('div');
	copyDom.innerText = str;
	copyDom.style.position = 'absolute';
	copyDom.style.top = '0px';
	copyDom.style.right = '-9999px';
	document.body.appendChild(copyDom);
	// 创建选中范围
	let range = document.createRange();
	range.selectNode(copyDom);
	// 移除剪切板中内容
	window.getSelection().removeAllRanges();
	// 添加新的内容到剪切板
	window.getSelection().addRange(range);
	// 复制
	let successful = document.execCommand('copy');
	copyDom.parentNode.removeChild(copyDom);
	try {
	uiMsg(successful ? '复制成功!' : '复制失败，请手动复制内容', null, successful ? 'success' : 'error');
	} catch (err) {}
	};

	// 下载 base64 格式的图片
	const uiDownloadImg = (data, fileName) => {
	var link = document.createElement('a');
	link.href = data;
	link.download = fileName;
	link.click();
	};

	export { uiCopy, uiDownloadImg };

# 全局的消息提示和 naiveui 的主题配置

naiveui 的 message 组件需要在 n-message-provider 内部并且使用 useMessage 去获取 API。在 components 中新建 provider 文件夹，然后新建 index.vue：

	<template>
	<n-config-provider :locale="zhCN" :date-locale="dateZhCN" :theme-overrides="themeOverrides">
	<n-message-provider>
	<Message />
	<slot></slot>
	</n-message-provider>
	</n-config-provider>
	</template>

	<script setup>
	import { NMessageProvider, NConfigProvider, NGlobalStyle } from 'naive-ui';
	import { zhCN, dateZhCN } from 'naive-ui';
	import Message from './Message.vue';

	const themeOverrides = reactive({
	common: {
	primaryColor: '#009688'
	},
	Menu: {
	itemTextColor: '#aaa',
	itemTextColorHover: '#fff',
	itemTextColorActive: '#fff',
	itemTextColorActiveHover: '#fff',
	itemTextColorChildActive: '#fff',
	itemTextColorChildActiveHover: '#fff',

	itemIconColor: '#aaa',
	itemIconColorHover: '#fff',
	itemIconColorActive: '#fff',
	itemIconColorChildActive: '#fff',
	itemIconColorActiveHover: '#fff',
	itemIconColorChildActiveHover: '#fff',

	itemColorHover: '#009688',
	itemColorActive: '#009688',
	itemColorActiveHover: '#009688',

	arrowColor: '#aaa',
	arrowColorHover: '#fff',
	arrowColorActive: '#fff',
	arrowColorChildActive: '#fff',
	arrowColorChildActiveHover: '#fff'
	}
	});
	</script>

这里笔者配置了菜单的颜色和默认语言为中文。如果不需要颜色配置则可以忽略 Menu。
下面来配置全局的消息提示：在 index.vue 同级新建 Message.vue 文件：

	<template></template>

	<script setup>
	import { useMessage } from 'naive-ui';

	const NMessage = useMessage();

	let loadingMessage = null;

	class Message {
	removeMessage() {
	if (loadingMessage) {
	loadingMessage.destroy();
	loadingMessage = null;
	}
	}

	showMessage(type, content, option = {}) {
	if (loadingMessage) {
	loadingMessage.destroy();
	loadingMessage = null;
	}
	loadingMessage = NMessage[type](content, { ...option, duration: option.duration !== undefined ? option.duration : 1500 });
	}

	loading(content) {
	this.showMessage('loading', content, { duration: 0 });
	}

	success(content, callback = () => {}) {
	this.showMessage('success', content, {
	onLeave: () => {
	callback();
	}
	});
	}

	error(content, callback = () => {}) {
	this.showMessage('error', content, {
	onLeave: () => {
	callback();
	}
	});
	}

	info(content, callback) {
	this.showMessage('info', content, {
	onAfterLeave: () => {
	callback && callback();
	}
	});
	}

	warning(content, callback) {
	this.showMessage('warning', content, {
	onAfterLeave: () => {
	callback && callback();
	}
	});
	}
	}

	window['$uiMsg'] = new Message();
	</script>

配置完成后需要到 App.vue 组件中引入 Provider：

	<template>
	<Provider>
	<router-view></router-view>
	</Provider>
	</template>

	<script setup>
	import Provider from './components/provider/index.vue';
	</script>

	<style lang="scss">
	.ui-flex {
	display: flex;
	.flex-1 {
	flex: 1;
	}
	&.align-start {
	align-items: flex-start;
	}
	&.align-center {
	align-items: center;
	}
	&.align-end {
	align-items: flex-end;
	}
	&.justify-center {
	justify-content: center;
	}
	&.justify-between {
	justify-content: space-between;
	}
	&.justify-around {
	justify-content: space-around;
	}
	&.justify-start {
	justify-content: flex-start;
	}
	&.justify-end {
	justify-content: flex-end;
	}
	&.flex-wrap {
	flex-wrap: wrap;
	}
	}
	</style>

这里配置好后，就可以使用 $uiMsg.success('成功') 来调用消息提示的组件了；
类型有 loading，success，error，info，warning ，可以根据需要增减。
笔者在这里还加入了全局 css 样式，不需要可以去掉。

# 6. 头部和左侧菜单组件

做完以上的配置之后项目大体结构已经搭建完毕，下面我们来编写公共的头部和左侧菜单组件。
在 components 文件夹下新建 layout 文件夹，新建 Header.vue 和 Menu.vue。

# 公共头部：

	<template>
	<div class="ui-flex align-center justify-end">
	<n-dropdown trigger="hover" :options="options" @select="Select">
	<n-button text type="info">
	（）<n-icon> <DownOutlined /></n-icon>
	</n-button>
	</n-dropdown>
	</div>
	</template>

	<script setup>
	import { DownOutlined } from '@vicons/antd';
	import { useUserStore } from '../../store/user';
	const user = useUserStore();
	const { trueName, loginName } = user.userInfo;

	const options = ref([
	{
	label: '退出登录',
	key: 'loginout'
	}
	]);
	const Select = key => {
	if (key === 'loginout') {
	user.LoginOut();
	}
	};
	</script>

	<style lang="scss" scoped>
	.ui-flex {
	height: 100%;
	padding-right: 10px;
	}
	</style>

# 公共左侧菜单：

	<template>
	<a href="./" class="logo"></a>
	<n-menu ref="menuRef" :options="menuOptions" v-model:value="selectedKey" />
	</template>

	<script setup>
	import { NIcon } from 'naive-ui';
	import { FileTextOutlined, SettingOutlined } from '@vicons/antd';
	import { RouterLink } from 'vue-router';

	const { $router } = getCurrentInstance().appContext.config.globalProperties;

	const menuOptions = [
	{
	label: () =>
	h(
	RouterLink,
	{
	to: {
	name: 'noPermission'
	}
	},
	{ default: () => '无权限' }
	),
	key: 'noPermission',
	icon: () => h(NIcon, null, { default: () => h(FileTextOutlined) })
	}
	];

	const menuRef = ref(null),
	selectedKey = ref('');
	onMounted(() => {
	let currentPath = $router.currentRoute.value.name;
	menuRef.value?.showOption(currentPath);
	selectedKey.value = currentPath;
	});
	</script>
	<style lang="scss" scoped>
	.logo {
	display: block;
	width: 200px;
	height: 50px;
	background: url('https://fakeimg.pl/200x50') no-repeat center center/200px 50px;
	}
	</style>
