Is there a .NET library for minifying Javascript?
提问by Hairgami_Master
I'm programatically creating javascript files from a .NET web app, and would like to minify it before passing it on to the user? Is there a library or technique for doing this on the fly?
我正在以编程方式从 .NET Web 应用程序创建 javascript 文件，并且想在将其传递给用户之前将其缩小？是否有库或技术可以即时执行此操作？
Thank
谢谢

If you simply want to be able to minify a javascript string in C# before saving it to a file, I would use either the MS Ajax Minifieror the YUI compressor for .net. Both of these expose an API that allows you to do this. Here is a sample using the ajax minifier:
如果您只是希望能够在将 C# 中的 javascript 字符串保存到文件之前对其进行缩小，我将使用MS Ajax Minifier或用于 .net的YUI 压缩器。这两者都公开了一个允许您执行此操作的 API。这是一个使用 ajax minifier 的示例：
var minifier = new Microsoft.Ajax.Utilities.Minifier();
var minifiedString = minifier.MinifyJavaScript(unMinifiedString);
Using the YUI Compressor for .net:
使用 .net 的 YUI 压缩器：
var minifiedString = JavaScriptCompressor.Compress(unMinifiedString);
Both the ajax minifier and and YUI Compressor libraries are available via Nuget.
ajax minifier 和 YUI Compressor 库都可以通过 Nuget 获得。

Why not to use javascript-written minifier directly in .NET (try if it works as JScript code). Uglify.js comes to mind...
为什么不直接在 .NET 中使用 javascript 编写的 minifier（尝试它是否作为 JScript 代码工作）。想到了 Uglify.js...

We use the C# port of JSMIN: http://www.koders.com/csharp/fidC8F76D32D2FB3B213046C30CD8B362820FFFD604.aspx?s=file#L15
我们使用JSMIN的C#端口：http: //www.koders.com/csharp/fidC8F76D32D2FB3B213046C30CD8B362820FFFD604.aspx?s =file#L15
It works pretty well.
它工作得很好。

i compact the files, upload, then undo the pack so i have the source code intact. i pack production code only.
我压缩文件，上传，然后撤消包，所以我有完整的源代码。我只打包生产代码。

You can use the Closure Compiler, but I wouldn't recommend you minifying files everytime a user visits your website. It's much better to build all the files before deploying new commits. Take a look at this article about tools.
您可以使用Closure Compiler，但我不建议您在每次用户访问您的网站时都缩小文件。在部署新提交之前构建所有文件要好得多。看看这篇关于工具的文章。

Well, I would think there are three things you need to do to minifya script file:
好吧，我认为您需要做三件事来缩小脚本文件：
- Shorten long variables
- Remove comments
- Remove needless whitespaces (tabs, spaces, carriage returns)
- 缩短长变量
- 删除评论
- 删除不必要的空格（制表符、空格、回车）
Those are all relatively simple to replace at runtime, but will take a bit of code writing. For the variable shortening, find like variables in their scope that are longer than, say 2 letters. Then abbreviate and have that follow through in the code block (the scope of the variable).
在运行时替换这些都相对简单，但需要编写一些代码。对于变量缩短，在其范围内找到比 2 个字母长的变量。然后缩写并在代码块（变量的范围）中进行。
Removing comments will be simple. Removing whitespaces are also easy. For singleline, find //and delete until a carriage return/newline feed. Whitespaces, replace tabs with a space, multiple spaces with a space, and carriage returns/newline feeds with a space.
删除评论很简单。删除空格也很容易。对于单行，查找//并删除直到出现回车/换行符。空格，用空格替换制表符，用空格替换多个空格，用空格替换回车/换行符。
