node.js - React + Webpack + Material UI 样式在生产中的突破

Question

我正在尝试使用 Material UI 创建一个可重用的 React 组件，并将其 npm link 到另一个应用程序。组件和应用程序使用 webpack 进行捆绑。该应用程序在开发中很好地渲染了组件，但是当我捆绑该应用程序时，该组件开始破坏 Material-ui 样式。

我尝试过的一些解决方案包括:

• https://material-ui.com/getting-started/faq/#why-arent-my-components-rendering-correctly-in-production-builds
• https://reactjs.org/warnings/invalid-hook-call-warning.html

我认为在 peerDependency 中定义 @material/core 可以解决这个问题，但每次我使用 Material-UI 组件时，应用程序都会抛出 Invalid Hook Call Warning .

似乎没什么作用☹️

组件的package.json:

组件的webpack.config.js

const path = require('path');

module.exports = {
  entry: './src/index.jsx',
  mode: 'production',
  output: {
    path: path.resolve(__dirname, 'build'),
    filename: 'index.js',
    libraryTarget: 'commonjs2',
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        include: path.resolve(__dirname, 'src'),
        exclude: /(node_modules|bower_components|build)/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/env'],
          },
        },
      },
    ],
  },
  resolve: { extensions: ['*', '.js', '.jsx'] },
  externals: {
    react: 'react',
  },
  optimization: {
    minimize: true,
  },
};

任何帮助将不胜感激!提前致谢。

如果您查看 npm link 上的文档，这实际上非常有意义。 :

First, npm link in a package folder will create a symlink in the global folder {prefix}/lib/node_modules/ that links to the package where the npm link command was executed.

请注意，该命令仅在本地创建符号链接(symbolic link)，因此当您构建/部署时，它在逻辑上会遵循无法找到的包。

我的建议是创建一个 scoped package为您的自定义组件。创建一个 npm 帐户，上传您的包，然后将其添加到您的项目中，如下所示:

npm install @brettoberg/reusable-component

现在，webpack 和任何其他系统应该能够找到它，因为它已发布。
