我正在尝试制作一个我正在开发的同构 React 应用程序。中的一个这样做的已知问题 https://reactjsnews.com/isomorphic-react-in-real-lifewebpack 加载器允许import/require非 JavaScript 资源（例如 CSS 文件）。例如
// ExampleComponent.jsx
import Select from 'react-select';
import 'react-select/dist/react-select.css';
如果使用 Express 构建应用程序，那么节点将进行此导入并失败，因为它无法处理 CSS 文件，它只需要 javascript（并且感谢babel-register JSX).
解决这个问题的方法之一是使用target: 'node'构建服务器应用程序（包括所有公共部分，例如组件，因为它是同构应用程序）时，webpack 中的选项来构建服务器端代码。这应该会导致server.js正在构建，然后可以由节点运行。
注意：我知道还有其他方法可以解决这个特定问题（例如不使用import/require包含任何不是 javascript 的内容，但在此应用程序的开发阶段不切实际。

问题是样式加载器利用window这显然在node环境中不存在。
$ node dist/server.js
/Users/dpwrussell/Checkout/ExampleApp/dist/server.js:25925
return /msie [6-9]\b/.test(window.navigator.userAgent.toLowerCase());
^
ReferenceError: window is not defined
From here https://github.com/webpack/style-loader/blob/master/addStyles.js#L14在样式加载器中。
感觉我已经非常接近完成这项工作了，所以任何想法都会受到欢迎。
