How to build efficient front-end applications through vue and Element-plus
With the continuous development of front-end technology, modern front-end application building tools and frameworks emerge in endlessly. As an efficient and flexible JavaScript framework, Vue.js has become the first choice for developers. Element-plus is a set of UI component libraries based on Vue.js. It provides many ready-made UI components to help us quickly build interfaces.
In this article, we will introduce how to use Vue.js and Element-plus to build efficient front-end applications. We will start from how to set up a development environment and then how to use Vue components and Element-plus components for development.
After installing Node.js, enter the following command on the command line to install Vue CLI:
npm install -g @vue/cli
After the installation is complete, use the following command to create a new Vue project:
vue create my-app
Then select "Manually select features" and press Enter. Next, press space to select functions such as “Babel”, “Router” and “Linter”.
After the installation is complete, run the following command in the project directory to install Element-plus:
npm install element-plus --save
Create a new folder layouts in the src directory and create a file MainLayout.vue in it. In this file, we will use Element-plus' components to build the layout:
<template> <div class="main-layout"> <el-container> <el-header> <!-- 顶部导航栏 --> </el-header> <el-container> <el-aside> <!-- 侧边栏 --> </el-aside> <el-main> <!-- 主要内容区域 --> <router-view></router-view> </el-main> </el-container> </el-container> </div> </template> <script> export default { name: 'MainLayout', } </script> <style scoped> .main-layout { height: 100vh; } </style>
Create a new folder router in the src directory and create a file index.js in it. In this file, we will use Vue Router for routing configuration:
import { createRouter, createWebHashHistory } from 'vue-router' import Home from '../views/Home.vue' const routes = [ { path: '/', name: 'Home', component: Home }, // 其他页面的路由配置... ] const router = createRouter({ history: createWebHashHistory(process.env.BASE_URL), routes }) export default router
Create a new folder views in the src directory and create a file Home.vue in it. In this file, we will use the components of Element-plus to build the page:
<template> <div class="home"> <el-card> <h2>Welcome to my App!</h2> </el-card> </div> </template> <script> export default { name: 'Home', } </script> <style scoped> .home { margin: 20px; } </style>
In the main.js file in the src directory, add the following code:
import { createApp } from 'vue' import App from './App.vue' import ElementPlus from 'element-plus' import 'element-plus/lib/theme-chalk/index.css' import router from './router' const app = createApp(App) app.use(ElementPlus) app.use(router) app.mount('#app')
At this point, we have completed a simple project built using Vue.js and Element-plus Front-end application. You can start the application by running the following command:
npm run serve
Summary:
Building efficient front-end applications with Vue.js and Element-plus is relatively simple. We only need to set up the development environment, create the basic layout and page components, and integrate them into the application. Element-plus's component library provides a rich set of UI components, allowing us to quickly build modern user interfaces. I hope this article can be helpful to you when building front-end applications using Vue.js and Element-plus.
