How to build efficient front-end applications with vue and Element-plus

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.

1. Building a development environment
   To use Vue.js and Element-plus, you first need to install Node.js. Node.js is a server-side running environment based on the Chrome V8 JavaScript engine, which includes the npm package management tool.

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

2. Create a basic layout
   Next, we will create a basic layout, Contains a top navigation bar and a sidebar.

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>

3. Create a routing configuration
   Next, we need to create a routing configuration to define the different pages of the application .

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

4. Create a page component
   For demonstration, we will create a simple Home page.

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 id="Welcome-to-my-App">Welcome to my App!</h2>
    </el-card>
  </div>
</template>

<script>
export default {
  name: 'Home',
}
</script>

<style scoped>
.home {
  margin: 20px;
}
</style>

5. Integrating the components and routing configuration into the application
   Finally, we need to combine the previously created components with Route configuration is integrated into the application.

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.
