捕捉/监听函数的执行 [英] Catch / Listen to function's execution

问题描述

我想添加到模块记录器中的所有功能.我想记录该功能的开始"时间和结束"时间.这样一来，我可以获得每个函数(同步函数)的执行时间.

I want to add to all functions in module logger. I want to log "start" time of the function and "end" time. So that's way I can get performance time of every function (sync functions).

但是我不知道如何使它工作..=( 我不想以某种动态的方式重写函数-我想在将来调试它们.所以需要保留原始代码-我需要找到某种方式来包装每个函数...

But I can't get how to make it work.. =( I don't want to rewrite functions in some dynamic way - I want to debug them in the future..So need to keep original code - I need to find some way to wrap every function...

让我们看一些例子:

module.exports = {
   someVar: "12345string",

   operation1: function(){
      alert("operation1");
   },

   operation2: function(){
      alert("operation2");
   }
};

一旦模块的功能被执行，我们需要运行一些"pre"和"post"执行脚本...

Once module's function executed, we need to run some "pre" and "post" execution script...

我该怎么做?请帮忙... 我有很多模块和功能... =(

How can I do this? Help please... I have a lot of modules and functions... =(

推荐答案

好！因此，我使用了 meld 软件包，效果很好！

OK! So I used meld package and that's works great!

正如吉姆·加里森(Jim Garrison)在评论中所说-每个AOP软件包/库都可以帮助解决该问题.

As Jim Garrison said in the comment - every AOP package/lib can help to solve that problem.

我发现Meld非常简单&清除.

I found meld as very simple & clear.
