vue——按需引入elementUI(以时间选择器为例)

参考:https://www.jianshu.com/p/40da0ba35ac1

1.  安装

npm install babel-plugin-component –D

2.  修改.babelrc

原babelrc:

{
  "presets": [
    ["env", {
      "modules": false,
      "targets": {
        "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
      }
    }],
    "stage-2"
  ],
  "plugins": ["transform-vue-jsx", "transform-runtime",]
}

修改后:

{
  "presets": [
    ["env", {
      "modules": false,
      "targets": {
        "browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
      }
    }],
    "stage-2"
  ],
  "plugins": ["transform-vue-jsx", "transform-runtime",
    ["component",{      // <==     "libraryName":"element-ui",// <==     "styleLibraryName":"theme-chalk" // <==     }
    ]
  ] }

3.  按需引入组件

main.js:

import Vue from 'vue';
import App from './App';
import { DatePicker } from 'element-ui';

Vue.use(DatePicker);

需要用到elementUI的组件:

<style scoped>
  @import 'https://unpkg.com/element-ui@2.3.7/lib/theme-chalk/index.css';
</style>
