Element Plus and other UI frameworks translate this sentence into English.

Element Plus and other UI frameworks provide Vue.js developers with a rich library of components and tools, significantly improving development efficiency and user experience. These frameworks not only encapsulate common interactive components but also support advanced features such as theme customization and internationalization, making them essential choices for modern web application development.

Core Features of Element Plus

Element Plus is a component library based on Vue 3, inheriting the design philosophy of Element UI while undergoing a comprehensive upgrade. Its core advantages include:

1. Component Richness: Offers over 55 high-quality components, including:

   • Form-related: Input, Select, DatePicker
   • Data display: Table, Tree, Tag
   • Feedback-related: Message, Notification, Dialog

2. TypeScript Support: Complete type definitions for safer development

import { ElButton } from 'element-plus'
// Clear props type hints
const buttonProps = defineProps<{
  size?: 'large' | 'default' | 'small'
}>()

3. Theme Customization System: Deep customization via SCSS variables

// Override theme variables
$--color-primary: #f56c6c;
@import "element-plus/theme-chalk/src/index";

Unique Advantages of Naive UI

// Naive UI offers more flexible on-demand importing
import { createDiscreteApi } from 'naive-ui'
const { message } = createDiscreteApi(['message'])

Advanced Usage Techniques

Dynamic Theme Switching Implementation

<template>
  <el-config-provider :locale="currentLocale">
    <app />
  </el-config-provider>
</template>

<script setup>
import zhCn from 'element-plus/es/locale/lang/zh-cn'
import en from 'element-plus/es/locale/lang/en'

const currentLocale = ref(zhCn)
const toggleLanguage = () => {
  currentLocale.value = currentLocale.value === zhCn ? en : zhCn
}
</script>

Table Performance Optimization

<el-table
  :data="tableData"
  :row-key="row => row.id"
  :virtual-scroll="true"
  height="500px"
>
  <el-table-column prop="date" label="Date" width="180" />
</el-table>

Common Problem Solutions

Deep Form Validation Integration

<el-form :model="form" :rules="rules" ref="formRef">
  <el-form-item prop="email" label="Email">
    <el-input v-model="form.email" />
  </el-form-item>
</el-form>

<script>
const rules = {
  email: [
    { type: 'email', message: 'Please enter a valid email', trigger: 'blur' }
  ]
}
</script>

Custom Component Extension

// Extending the Message component
import { ElMessage } from 'element-plus'

export function successMessage(options) {
  return ElMessage({
    type: 'success',
    duration: 3000,
    ...options
  })
}

Performance Optimization Practices

1. On-Demand Import Configuration

// vite.config.js
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'

export default {
  plugins: [
    Components({
      resolvers: [ElementPlusResolver()]
    })
  ]
}

2. Lazy Loading Components

<template>
  <el-dialog v-model="visible">
    <AsyncComponent />
  </el-dialog>
</template>

<script setup>
const AsyncComponent = defineAsyncComponent(() =>
  import('./Component.vue')
)
</script>

Enterprise-Level Application Adaptation

Permission Control Integration

<el-button v-permission="'user:create'">
  Create User
</el-button>

// Directive implementation
app.directive('permission', {
  mounted(el, binding) {
    if (!checkPermission(binding.value)) {
      el.parentNode?.removeChild(el)
    }
  }
})

Deep Integration with Multilingual Solutions

// Merging Element Plus and custom language packs
import elementLocale from 'element-plus/es/locale/lang/en'
import customLocale from './locales/en.json'

const i18n = createI18n({
  locale: 'en',
  messages: {
    en: { ...elementLocale, ...customLocale }
  }
})

Future Development Trends

1. Web Components Compatibility

// Experimental feature
import { defineCustomElement } from 'vue'
import ElButton from 'element-plus/es/components/button'

customElements.define('el-button', defineCustomElement(ElButton))

2. Exploration of Headless Component Patterns

<template>
  <el-select-v2
    :options="options"
    v-model="selected"
    :render-label="renderLabel"
  />
</template>

<script setup>
const renderLabel = ({ option }) => {
  return h('div', { class: 'custom-label' }, [
    h('span', { class: 'text' }, option.label),
    h('el-tag', { size: 'small' }, option.tag)
  ])
}
</script>
