具有最少文件数的 Angular ng 构建？ (仅支持 Chrome 也可以)

Question

当我构建我的 angular 项目时，我看到
main-es5.js和 main-es2015.js两个文件。我只想支持 Chrome 浏览器如何关闭构建旧的 js 文件我希望 Build.js 上的文件数量最少。

自从我升级到 8 以来，我的 Build 也运行了两次

笔记

Build time has significantly increased and i get the warning WARNING in budgets, maximum exceeded for initial.

这是我的 Angular.json 文件

      "optimization": true,
      "outputHashing": "none",
      "sourceMap": true,
      "extractCss": false,
      "namedChunks": false,
      "showCircularDependencies": false,
      "aot": true,
      "extractLicenses": false,
      "statsJson": false,
      "progress": true,
      "vendorChunk": false,
      "buildOptimizer": true,
