Question

当使用带有快速服务器的webpack-dev-middle时，我想使用webpack-hot-middleware对提取的css文件进行工作（热重载）。

它适用于webpack-dev-server。但是我想用快递来使用它。

server.js

＆＃13;

const express = require('express');
const webpack = require('webpack');
const webpackDevMiddleware = require('webpack-dev-middleware');

const app = express();
const config = require('./webpack.config.js');
const compiler = webpack(config);

app.set('view engine', 'pug')

// Tell express to use the webpack-dev-middleware and use the webpack.config.js
// configuration file as a base.
app.use(webpackDevMiddleware(compiler, {
  publicPath: config.output.publicPath
}));
// HMR
app.use(require("webpack-hot-middleware")(compiler, {
  log: console.log,
  path: '/__webpack_hmr',
  heartbeat: 10 * 1000
}));
// Render/serve HTML
app.get('/', (req, res) => {
  res.render('layout')
})

// Serve the files on port 3000.
app.listen(3000, function() {
  console.log('Example app listening on port 3000!\n');
});

＆＃13;

webpack.config.js

＆＃13;

const path = require('path')
const webpack = require('webpack')
const webpackHotMiddleware = require('webpack-hot-middleware')
const hotMidConf = 'webpack-hot-middleware/client?path=/__webpack_hmr&timeout=20000'

module.exports = {
  mode: 'development',
  entry: {
    bundle: [hotMidConf, './src/index.js'],
    style: [hotMidConf, './src/style.scss']
  }, 
  output: {
    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'),
    publicPath: '/'
  },
  devtool: 'inline-source-map',
  module: {
    rules: [
      {
        test: /\.js$/,
        use: 'babel-loader'
      },
      {
        test: /\.scss$/,
        use: [
          {
            loader: 'file-loader',
            options: {
              name: 'style.css'
            }
          },
          {
            loader: 'extract-loader',
            options: {
              publicPath: './'
            }
          },
          {loader: 'css-loader'},
          {
            loader: 'sass-loader',
            options: {
              includePaths: [path.resolve(__dirname, 'node_modules')]
            } 
          }
        ]
      },
    ]
  },
  plugins: [
    new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin()
  ]
}

其他所有工作，当我构建时，我从scss获取css文件。我相信style-loader是什么让它在没有被提取时起作用，但当我尝试使用它时似乎没有做任何事情。

我使用extract-text-webpack-plugin找到了很多答案，但据我所知，这对webpack 4不起作用......所以我使用了带文件加载器的extract-loader。
