Question

我已经和这个人转了一圈了，我认为是时候寻求帮助了。

我有一个奇怪的用例，我需要将打字稿转换成一个单独的包，将.css打包成一个文件，还复制所有不是.js，.ts或.css的其他文件。这些文件最终被保存到服务器，我们用于表单的软件将使用该服务器。它们不能包含.html，因此我在网上找到的大多数资源在我的用例中都无法使用。

无论出于何种原因，我都遇到了错误，而且我真的不知道从这里去哪里。

我的devDependencies如下：

"extract-text-webpack-plugin": "^3.0.2",
"ts-loader": "^6.2.1",
"typescript": "^3.7.2",
"webpack": "^4.41.2",
"webpack-cli": "^3.3.10",

我的webpack.config.js看起来像这样：

const path = require('path');
const glob = require('glob');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const combineLoaders = require('webpack-combine-loaders');

module.exports = {
  entry: glob.sync('./forms/**/index.ts').reduce((acc, path) => {
    const entry = path.replace('/index.ts', '')
    acc[entry] = path
    return acc
}, {}),
  devtool: 'inline-source-map',
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: [
          {
            loader: 'ts-loader',
            options: {
              transpileOnly: true,
              experimentalWatchApi: true,
            }
          }
        ],
        exclude: /node_modules/,
      },
      {
        test: /\.css$/,
        loader: ExtractTextPlugin.extract(
          'style-loader',
          combineLoaders([{
            loader: 'css-loader',
            query: {
              modules: true,
              localIdentName: '[name]__[local]___[hash:base64:5]'
            }
          }])
        )
      }
    ]
  },
  resolve: {
    extensions: [ '.tsx', '.ts', '.js' ],
  },
  output: {
    filename: './[name]/customBundle.js',
    path: path.resolve(__dirname, './public')
  },
  plugins: [
    new ExtractTextPlugin('styles.css')
  ]
};

这是我得到的错误：

更新：主要在工作。现在，我只需要能够处理.scss。

const path = require('path');
const glob = require('glob');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  plugins: [
    new MiniCssExtractPlugin({
      filename: './[name]/customBundle.css',
      chunkFilename: '[id].css',
      ignoreOrder: false
    })
  ],
  entry: glob.sync('./forms/**/index.ts').reduce((acc, path) => {
    const entry = path.replace('/index.ts', '');
    acc[entry] = path;
    return acc;
  }, {}),
  devtool: 'inline-source-map',
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: [
          {
            loader: 'ts-loader',
            options: {
              transpileOnly: true,
              experimentalWatchApi: true
            }
          }
        ],
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        use: [
          {
            loader: MiniCssExtractPlugin.loader,
            options: {
              hmr: process.env.NODE_ENV === 'development'
            }
          },
          'css-loader'
        ]
      }
    ]
  },
  resolve: {
    extensions: ['.tsx', '.ts', '.js']
  },
  output: {
    filename: './[name]/customBundle.js',
    path: path.resolve(__dirname, './public')
  }
};

这很可能与在Webpack 4中使用ExtractTextPlugin有关：

https://github.com/webpack-contrib/extract-text-webpack-plugin#usage

将您的配置迁移到https://github.com/webpack-contrib/mini-css-extract-plugin

使用Webpack将.ts和.css捆绑为单个文件
