1. Eject the project

npm run eject

2. Add multiple entry to webpack.config.dev.js

entry: {  
    index: [
      require.resolve('react-dev-utils/webpackHotDevClient'),
      require.resolve('./polyfills'),
      require.resolve('react-error-overlay'),
      paths.appIndexJs,
    ],
    admin:[
      require.resolve('react-dev-utils/webpackHotDevClient'),
      require.resolve('./polyfills'),
      require.resolve('react-error-overlay'),
      paths.appSrc + "/admin.js",
      ]
  },
  output: {
    path: paths.appBuild,
    pathinfo: true,
    filename: 'static/js/[name].bundle.js',
    chunkFilename: 'static/js/[name].chunk.js',
    publicPath: publicPath,
    devtoolModuleFilenameTemplate: info =>
      path.resolve(info.absoluteResourcePath),
  },

3. Modify HtmlWebpackPlugin 
add a new plugin node:

    new HtmlWebpackPlugin({
      inject: true,
      chunks: ["index"],
      template: paths.appHtml,
    }),
    new HtmlWebpackPlugin({
      inject: true,
      chunks: ["admin"],
      template: paths.appHtml,
      filename: 'admin.html',
    }),

4. webpack Dev Server 
rewrite urls

/config/webpackDevServer.config.js:

    historyApiFallback: {
      disableDotRule: true,
      // 指明哪些路径映射到哪个html
      rewrites: [
        { from: /^/admin.html/, to: '/build/admin.html' },
      ]
    }
