# babel-plugin-externals

将es module中的import语句代码编译为引用全局变量，如下示例所示，配置的externals选项为

```js
# externals
const options = {vue: 'Vue', react: 'React', 'react-dom': 'ReactDOM'}
```

```js
import {renderList as _renderList, Fragment as _Fragment} from "vue"

console.log(_renderList, _Fragment)

// 不在externals排除选项中，跳过
import {defineConfig} from "vite"

console.log(defineConfig)

import * as VUE from "vue"

console.log(VUE)

import Vue, {Abc as abc} from "vue"

console.log(Vue, abc)
```

转换后

```js
const {
    renderList: _renderList,
    Fragment: _Fragment
} = Vue;
console.log(_renderList, _Fragment);
import {defineConfig} from "vite";

console.log(defineConfig);
const VUE = Vue;
console.log(VUE);
const Vue = Vue;
const {
    Abc: abc
} = Vue;
console.log(Vue, abc);
```
