使用ng build --prod剥离所有注释和console.logs，可能吗? [英] Stripping all comments and console.logs with ng build --prod, possible?

问题描述

我正在使用MEAN，Angular 2，Node/Express，Angular-CLI和ng build --prod来构建我的应用程序，并且我在整个应用程序中都有大量注释掉的废弃代码和十亿个调试console.log语句.有没有一种方法可以让构建过程在构建时删除所有注释和console.log语句?手动执行此操作的想法很可怕！

I am using MEAN, Angular 2, Node/Express, Angular-CLI and ng build --prod to build my app and I have a travesty of commented out throwaway code and a billion debugging console.log statements throughout my app. Is there a way to have the build process remove all comments and console.log statements when it builds? The thought of doing it manually is scary!

推荐答案

我有一个简单的解决方法.将此代码放入main.ts

I have simple fix. Put this code in main.ts

if(env === 'prod') { // assuming you have env variable configured
  // check if window exists, if you render backend window will not be available 
  if(window){
      window.console.log = function(){};
   }
}
