webpack - webpack-dev-server 看起来与 webpack 构建不同

Question

我有这两个脚本：

"start": "webpack-dev-server --mode development --open --hot",
"build": "webpack --mode none",

yarn build结果是：

虽然yarn start结果是：

差异很小，但构建版本 Material UI Drawer 明显没有服务器版本那么宽，并且像素宽度也存在差异。

// webpack.config.js

const Dotenv = require('dotenv-webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ESLintPlugin = require('eslint-webpack-plugin');
const path = require('path');

module.exports = {
  devtool: 'eval-cheap-source-map',
  entry: './src/index.tsx',
  resolve: {
    alias: {
      Components: path.resolve(__dirname, 'src/components/'),
      Helpers: path.resolve(__dirname, 'src/helpers/'),
      Src: path.resolve(__dirname, 'src/'),
      Assets: path.resolve(__dirname, 'src/assets/'),
    },
    extensions: ['.ts', '.tsx', '.js'],
  },
  output: {
    path: __dirname + '/dist',
    publicPath: '/',
    filename: 'bundle.js',
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        loader: 'ts-loader',
      },
      {
        test: /\.(png|jpe?g|gif|svg)$/i,
        use: [
          {
            loader: 'file-loader',
          },
        ],
      },
    ],
  },
  devServer: {
    historyApiFallback: {
      index: '/',
    },
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './src/index.html',
    }),
    new Dotenv(),
    new ESLintPlugin(),
  ],
};

任何人都知道为什么服务器和构建版本之间存在视觉差异？
