推荐一款vue3 按需加载神器 unplugin-vue-components

今天给大家推荐一款vue3 按需加载神器 unplugin-vue-components，该插件可以自动导入ui库,还内置了大多数流行库解析器

1、安装

npm install unplugin-vue-components -D

2、使用

Vite配置

// vite.config.js
import { defineConfig } from 'vite'
import Components from 'unplugin-vue-components/vite'
import {
  ElementPlusResolver,
  AntDesignvueResolver,
  VantResolver,
  HeadlessUiResolver,
  ElementUiResolver
} from 'unplugin-vue-components/resolvers'

export default defineConfig({
  plugins: [
    Components({
      // ui库解析器，也可以自定义
      resolvers: [
        ElementPlusResolver(),
        AntDesignvueResolver(),
        VantResolver(),
        HeadlessUiResolver(),
        ElementUiResolver()
      ]
    })
  ]
})

Webpack配置

// webpack.config.js
const components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver,AntDesignvueResolver,VantResolver,HeadlessUiResolver,ElementUiResolver } = require('unplugin-vue-components/resolvers')

module.exports =
  plugins: [
    Components({
      resolvers: [
         AntDesignvueResolver(),
         ElementPlusResolver(),
         VantResolver(),
         HeadlessUiResolver(),
         ElementUiResolver()
      ]
    })
  ]
}

插件会生成一个ui库组件以及指令路径components.d.ts文件

// components.d.ts

// generated by unplugin-vue-components
// We suggest you to commit this file into source control

declare module 'vue' {
  export interface GlobalComponents {
    ElAside: typeof import('element-plus/es')['ElAside']
    ElButton: typeof import('element-plus/es')['ElButton']
    ElContainer: typeof import('element-plus/es')['ElContainer']
    ElDropdown: typeof import('element-plus/es')['ElDropdown']
    ElDropdownItem: typeof import('element-plus/es')['ElDropdownItem']
    ElDropdownMenu: typeof import('element-plus/es')['ElDropdownMenu']
    ElHeader: typeof import('element-plus/es')['ElHeader']
    ElIcon: typeof import('element-plus/es')['ElIcon']
    ElMain: typeof import('element-plus/es')['ElMain']
    ElMenu: typeof import('element-plus/es')['ElMenu']
    ElMenuItem: typeof import('element-plus/es')['ElMenuItem']
    ElResult: typeof import('element-plus/es')['ElResult']
  }
}

export { }
