npm install -g @vue/cli
vue create my-project cd my-project
npm install ant-design-vue
配置main.js
import Vue from 'vue' import App from './App.vue' import Antd from 'ant-design-vue'; import 'ant-design-vue/dist/antd.css'; // 引入样式 Vue.use(Antd); Vue.config.productionTip = false; new Vue({ render: h => h(App), }).$mount('#app');
mkdir src/components mkdir src/views
配置路由
修改router/index.js
:
import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld.vue' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'HelloWorld', component: HelloWorld } ] })
创建一个简单的Vue组件,例如HelloWorld.vue
:
<template> <div class="hello"> <h1>欢迎使用Ant Design Vue!</h1> </div> </template> <script> export default { name: 'HelloWorld', props: { msg: String } } </script> <style scoped> .hello { text-align: center; } </style>
在main.js
中引入并使用Ant Design-vue组件库,已经在前面的安装步骤中完成了。
创建Login.vue
组件:
<template> <div class="login-container"> <a-card title="登录表单"> <a-form-model :model="form" :rules="rules" ref="loginForm" @submit="onSubmit"> <a-form-model-item label="用户名" prop="username"> <a-input v-model="form.username" /> </a-form-model-item> <a-form-model-item label="密码" prop="password"> <a-input v-model="form.password" type="password" /> </a-form-model-item> <a-form-model-item> <a-button type="primary" html-type="submit" :loading="loading" @click="submitForm">登录</a-button> </a-form-model-item> </a-form-model> </a-card> </div> </template> <script> export default { name: 'Login', data() { return { form: { username: '', password: '' }, rules: { username: [ { required: true, message: '请输入用户名', trigger: 'blur' } ], password: [ { required: true, message: '请输入密码', trigger: 'blur' } ] }, loading: false } }, methods: { submitForm() { this.$refs.loginForm.validate(valid => { if (valid) { this.loading = true; setTimeout(() => { this.loading = false; this.$router.push('/'); }, 1000) } else { console.log('提交失败') return false } }) } } } </script> <style scoped> .login-container { width: 300px; margin: 100px auto; } </style>
修改router/index.js
,添加登录页面的路由:
import Vue from 'vue' import Router from 'vue-router' import HelloWorld from '@/components/HelloWorld.vue' import Login from '@/views/Login.vue' Vue.use(Router) export default new Router({ routes: [ { path: '/', name: 'HelloWorld', component: HelloWorld }, { path: '/login', name: 'Login', component: Login } ] })
在App.vue
中使用router-view
:
<template> <router-view></router-view> </template> <script> export default { name: 'App' } </script> <style> #app { font-family: 'Avenir', Helvetica, Arial, sans-serif; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; text-align: center; color: #2c3e50; margin-top: 60px; } </style>常见组件使用教程
Card组件用于展示内容,通常包含标题、正文和操作按钮等。
<template> <a-card title="卡片标题"> <p>卡片的内容</p> <a-button type="primary">操作按钮</a-button> </a-card> </template>
Row和Col组件用于布局,实现栅格化布局。
<template> <a-row> <a-col :span="12"> <a-card title="第一栏"> 这是第一栏的内容。 </a-card> </a-col> <a-col :span="12"> <a-card title="第二栏"> 这是第二栏的内容。 </a-card> </a-col> </a-row> </template>
Space组件用于在组件之间添加间隔。
<template> <a-space> <a-button type="primary">按钮1</a-button> <a-button type="primary">按钮2</a-button> <a-button type="primary">按钮3</a-button> </a-space> </template>
Form组件用于创建表单,可以包含多个输入项。
<template> <a-form-model :model="form" :rules="rules" ref="form" @submit="onSubmit"> <a-form-model-item label="用户名" prop="username"> <a-input v-model="form.username" /> </a-form-model-item> <a-form-model-item label="密码" prop="password"> <a-input v-model="form.password" type="password" /> </a-form-model-item> <a-form-model-item> <a-button type="primary" html-type="submit" @click="submitForm">提交</a-button> </a-form-model-item> </a-form-model> </template> <script> export default { data() { return { form: { username: '', password: '' }, rules: { username: [ { required: true, message: '请输入用户名', trigger: 'blur' } ], password: [ { required: true, message: '请输入密码', trigger: 'blur' } ] } } }, methods: { submitForm() { this.$refs.form.validate(valid => { if (valid) { alert('提交成功!') } else { console.log('提交失败') return false } }) } } } </script>

[Vue warn]: Unknown custom element: <a-button> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
解决方案:
确保在主组件中正确注册了Ant Design-vue组件库:
import Antd from 'ant-design-vue'; import 'ant-design-vue/dist/antd.css'; Vue.use(Antd);
样式看起来不对或未加载
解决方案:
确保正确引入了Ant Design-vue的CSS文件:
import 'ant-design-vue/dist/antd.css';
尽量减少DOM操作,使用虚拟DOM的机制来优化性能。
<template> <div v-if="show">显示内容</div> <div v-else>隐藏内容</div> </template> <script> export default { data() { return { show: true } }, methods: { toggle() { this.show = !this.show; } } } </script>
异步组件的加载可以提高应用的启动速度。
import {defineAsyncComponent} from 'vue'; const AsyncComponent = defineAsyncComponent(() => import('./Component.vue')); <template> <component :is="AsyncComponent"></component> </template>
安装Vue Devtools
插件,用于Vue应用的调试。
npm install --save-dev vue-devtools
使用jest
和vue-test-utils
进行单元测试。
npm install --save-dev jest vue-test-utils
// example.spec.js import { shallowMount } from '@vue/test-utils'; import MyComponent from '@/components/MyComponent.vue'; describe('MyComponent.vue', () => { it('renders correctly', () => { const wrapper = shallowMount(MyComponent); expect(wrapper.element).toMatchSnapshot(); }); });项目部署与发布
使用npm run build
命令打包项目,然后将生成的dist
文件夹的内容发布到服务器上。
npm run build
配置Nginx服务器以部署Vue应用。以下是Nginx的配置文件示例:
server { listen 80; server_name example.com; root /var/www/html; index index.html index.htm; location / { try_files $uri $uri/ /index.html; } }
将静态资源发布到CDN,加快访问速度。
