# Webpack 知识点回顾
* `webpack` 构建 `production` 环境下代码时，会自动 `tree shaking` 清理无用多余的代码。但是检查不到函数和 `scope(块)`内部，无法 `tree shaking`。
```js
import lodash from 'lodash-es';
const sync = function () {
console.log('Sync')
}
const isArray = function (args) { // 此函数没有调用过，按理 tree shaking 会把 lodash、isArray 去除，但并没有
console.log(lodash.isArray(args))
}
export {
sync,
isArray
}
```
* 启用 `CSS modules`，根据文件夹为一个模块，在外面通过 module.test 的方式使用
