1.安装webpack-bundle-analyzer
2.config/index.js文件中

module.exports = {
  build: {
  ...
    // Run the build command with an extra argument to
    // View the bundle analyzer report after build finishes:
    // `npm run build --report`
    // Set to `true` or `false` to always turn it on or off
    bundleAnalyzerReport: process.env.npm_config_report
  }
  ...
}

3.webpack生产环境中 build/webpack.prod.conf.js文件中

if (config.build.bundleAnalyzerReport) {
  var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
  webpackConfig.plugins.push(new BundleAnalyzerPlugin())
}

5.npm run build --report
等待构建完成后，在浏览器中输入localhost:8888打开分析结果
