Question

我正在使用React / Node和CSS模块实现服务器端渲染。

我引入了mini-css-extract-plugin从JS中提取CSS，并且该插件未在公共文件夹（或任何位置）中创建CSS文件。

/package.json

{

  "main": "webpack.config.js",
  "scripts": {
    "server": "babel-node ./src/server/index.js",
    "client": "webpack --watch --progress",
    "start": "yarn server & yarn client"
  },
  ...
  "devDependencies": {

    "webpack": "^4.29.6",
    "webpack-cli": "^3.3.0",
    "webpack-node-externals": "^1.7.2"
  }
}

/webpack.config.js

const path = require('path');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
  mode: 'production',
  entry: './src/client/index.js',
  target: 'node',
  output: {
    path: path.resolve(__dirname, 'public'),
    filename: 'build.js',
    publicPath: '/',
  },
  resolve: {extensions: ['.js', '.css']},
  watch: false,
  plugins: [new MiniCssExtractPlugin({filename: 'styles.css'})],
  module: {
    rules: [
      {
        test: /\.css$/,
        sideEffects: true,
        use: [{loader: MiniCssExtractPlugin.loader}, 'css-loader'],
      },
      {
        test: /\.js?$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
        options: {
          cacheDirectory: true
        }
      }
    ]
  }
}

/。babelrc

{
    "presets": ["@babel/env", "@babel/react"],
    "plugins": [
        "@babel/plugin-syntax-dynamic-import",
        "@babel/plugin-proposal-class-properties",
        ["css-modules-transform", {
          "generateScopedName": "[name]__[local]___[hash:base64:5]"
        }]
    ]
}

我希望看到在/public/styles.css中创建了以下文件，并且现在在该文件夹或其他任何位置都没有文件被创建。感谢您的帮助！

检查我的以下配置

const MiniCssExtractPlugin = require("mini-css-extract-plugin");

module.exports = {
    plugins: [
        new MiniCssExtractPlugin({
            filename: "[name].css",
            chunkFilename: "[id].css"
        }),
   ],
    module: {
        rules: [{
                test: /\.scss$/,
                use: [
                    'style-loader',
                    MiniCssExtractPlugin.loader,
                    {
                        loader: "css-loader",
                        options: {
                            minimize: true,
                            sourceMap: true
                        }
                    },
                    {
                        loader: "sass-loader"
                    }
                ]
            }
        ]
    }

如果您仍有问题，请告诉我

MiniCssExtractPlugin没有创建CSS文件
