JavaScript压缩 [英] JavaScript compression

问题描述

我寻找可以压缩JavaScript源代码的工具。我发现一些只删除空白字符的网络工具？但也许存在更好的工具，可以压缩用户的函数名称，字段名称，删除未使用的字段，其他。

解决方案

通常用于压缩JS代码的工具是
$ b

$ b

   -  nomunge 
仅限缩小。不要模糊局部符号。 
  

它应该能够做你想要的。

这里是一篇关于它的文章：介绍YUI Compressor 。

引用该文章：

它从分析源代码
JavaScript文件开始，以了解它如何构造
。然后它打印出
令牌流，用1（或2或3）字母
符号替换所有本地
符号，只要这样的替换是
适当

作为sidenote：不要忘记gzip您的JS / CSS文件，当从您的网络服务器提供：

例如，如果您使用Apache，请查看 mod_deflate 。

I look for tool which can compress JavaScript source code. I found some web tools which only deletes whitespace chars? But maybe exist better tool which can compress user's function names, field name, deletes unused fields, others.

解决方案

A tool often used to compress JS code is the YUI Compressor.

Considering there is this option :

--nomunge
    Minify only. Do not obfuscate local symbols.

It should be able to do what you asked.

And here is an article about it : Introducing the YUI Compressor.

Quoting that article :

It starts by analyzing the source JavaScript file to understand how it is structured. It then prints out the token stream, replacing all local symbols by a 1 (or 2, or 3) letter symbol wherever such a substitution is appropriate

As a sidenote : don't forget to gzip your JS/CSS files, when serving them from your webserver : this will reduce the size of data that goes through the network quite a lot !

For instance, if you are using Apache, take a look at mod_deflate.
