JavaScript 剥离器:删除网页中未使用的函数/对象 [英] JavaScript stripper: remove functions/objects that are not used in a web page

问题描述

我所有的网页都使用 JavaScript 库，为了提高我的网页的性能，我会根据每个页面的需要从库中删除所有不必要的函数/对象.我正在寻找一种可以自动进行智能剥离的工具.

All of my web pages use a JavaScript library, to improve the performance of my web page, I'd remove all the unnecessary functions/objects from the library for each page according to what's needed for those individual pages. I'm looking for a tool that can do the intelligent stripping automatically.

或者相反的方向.它还需要一个工具来为特定页面从 JavaScript 库中仅提取真正需要的函数和对象.

Or in the opposite direction. it will do also to have a tool to extract only the really needed functions and objects from a JavaScript library for a particular page.

感谢您的帮助，

推荐答案

对我来说，这听起来像是非常不成熟的优化.您是否验证过您不使用的库函数的存在会导致性能问题?如果真是这样，我会感到非常惊讶.

This sounds like very premature optimization to me. Have you verified the mere presence of the library functions you aren't using are causing performance problems? I would be very surprised if that is truly the case.

一如既往，代码优先，只有在您发现性能问题、分析和隔离原因后才进行优化.

As always, code first, only optimize after you've recognized a performance problem, profiled and isolated the cause.
