从角度构建中删除代码

Question

我想知道如何提高angular2 +开发的效率。目前，我有一份登记表。此注册表单模型在开发期间填充了实际数据，并在构建之前手动删除。

如果你在prod模式下编译，是不是有办法告诉'编译器'，只是忽略它！某种类似这种伪代码的预处理器代码：

let rdata = {id:null, pass:null}
@@ignoreprod_start
  rdata.id = 2766;
  rdata.pass = "@(F-§44$A_NG%%p";
@@ignoreprod_end

Answer 1

我在Angular 4和5中工作过，我们有angular-cli.json，这个文件有apps.environments属性，你可以在其中指定编译器。附加我的文件只是为了参考，这只是一个指针而不是一个完整的答案，你需要亲自看看你能做什么，但请问我有什么说明，这个文件environment.prod.ts和environment.ts在环境中定义文件夹，它取决于您使用的角度版本
