webpack-dev-server+react 编译完成后浏览器里没有文件？

Question

"webpack": "^4.41.2",
"webpack-cli": "^3.3.9",
"webpack-dev-server": "^3.9.0"
我在终端用webpack-dev-server命令
控制台显示的是成功了，也没有报错
但是打开浏览器之后发现根本就没有打包好的文件

我尝试过iframe模式，frame里面src="javascript:;"也没有文件的连接
不知道打包的文件都打包到哪里去了
配置如下

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const webpack = require('webpack');

module.exports = {
  entry: {
    devpage: './devpage/index.jsx',
    querypage: './querypage/index.jsx',
  },

    filename: '[name].js',
    path: path.resolve(__dirname, 'dist'),

  resolve: {
    extensions: ['.wasm', '.mjs', '.js', '.jsx', '.json'],

  module: {
    rules: [
      {
        test: /\.css$/,
        use: [

          'css-loader',
        ],
      },
      {
        test: /\.jsx$/,
        exclude: /(node_modules|bower_components)/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env', '@babel/preset-react'],
            plugins: [],
          },
        },
      },
      {
        enforce: 'pre',
        test: /\.jsx$/,
        exclude: /node_modules/,
        loader: 'eslint-loader',
        options: {
        // eslint options (if necessary)
        },
      },
    ],
  },
  plugins: [
    new CleanWebpackPlugin(),
    new HtmlWebpackPlugin({

  },

  devtool: 'inline-source-map',
  devServer: {
    hot: true,
    contentBase: path.resolve(__dirname, 'dist'),
    progress: true,
    inline: true,

  },
};
