@Daniel Khoroshko的回答解决了我的统计问题。作为参考，webpack可以（至少）有四种方法处理stats：

将stats当作常规webpack选项https://webpack.js.org/configuration/stats/
如果使用devServer，则必须将其放置在该对象中（请参见上面链接中的注意事项）
如果使用Node API，则必须在回调函数中使用https://webpack.js.org/api/node/#stats-object
如Daniel所指出，webpack-dev-middleware会覆盖stats，因此对象必须在其中https://github.com/webpack/webpack-dev-middleware#stats

================================================

我正在尝试抑制我得到的数百万条extract-text-webpack-plugin日志，使用webpack 3.10。

我们正在使用webpack Node API。在我们的node入口点server.js中，我们有如下内容：

// server.js

const app = express();

if (environment.isLocal) {
  require('./webpackConfig')(app);
} else {
  app.use(compression());
}
// other stuff

我们在哪里使用带有Node的webpack:

// webpackConfig.js

const webpack = require('webpack');
const config = require('../webpack.config.dev');

module.exports = (app) => {
  const compiler = webpack(config, (err, stats) => {
    stats.toJson("none"); // none for brevity, but not working
  });

  app.use(require('webpack-dev-middleware')(compiler, {
    noInfo: true,
    publicPath: config.output.publicPath
  }));

  app.use(require('webpack-hot-middleware')(compiler));
};

最后，整个配置

// webpack.config.dev.js

module.exports = {
  devtool: 'cheap-module-source-map',
  entry: {
    app: [
      'eventsource-polyfill',
      'webpack-hot-middleware/client?reload=true',
      './src/index'
    ]
  },
  target: 'web',
  output: {
    path: __dirname + '/dist',
    publicPath: '/',
    filename: '[name].js'
  },
  devServer: {
    contentBase: './src'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
    new ExtractTextPlugin('[name]-[hash].css'),
    new HtmlWebpackPlugin({
      title: 'annoying webpack', 
      template: './src/index.html', 
      alwaysWriteToDisk: true,
      inject: false
    }),
    new HtmlWebpackHarddiskPlugin()
  ],
  module: {
    rules: [
      {
        test: /\.js$/,
        enforce: 'pre',
        loader: require.resolve('eslint-loader'),
        options: {
          failOnWarning: false,
          failOnError: false
        },
        exclude: /node_modules|dist/
      },
      {
        test: /\.js$/,
        include: [path.join(__dirname, 'src')]
        loader: 'babel-loader'
      }
    ]
  }
};

在控制台中输出

关于统计选项，webpack-dev-middleware和webpack-dev-server都有自己的统计设置，我认为这会覆盖 webpack 自己的设置。建议尝试这样做。

  app.use(require('webpack-dev-middleware')(compiler, {
    noInfo: true,
    publicPath: config.output.publicPath,
    stats: 'errors-only'
  }));
