Jazmin, the JavaScript Source-Compressor

Jazmin is a console-based utility and an MSBuild task that filters JavaScript by removing comments and unnecessary whitespace. It typically reduces the size of the script by half, resulting in faster downloads. It also encourages a more expressive programming style because it eliminates the download cost of clean, literate self-documentation. Jazmin does not modify the behavior of the original JavaScript source in any way.

Jazmin is a straight C# port of JavaScript Minifier that was originally written by Douglas Crockford in C. Jazmin behaves identically to JSMin so all the documentation on JSMin also applies to Jazmin.

Download

Download Jazmin v1.0 (build 8417) . It includes C# source code as well as binaries compiled in debug and release configurations.

Note: Jazmin's MSBuild task is also available as part of the open source MSBuild Community Tasks Project (see the JSCompress task) as of version 1.2. The version provided in the download here is a stand-alone assembly of the same MSBuild task. The MSBuild Community Tasks Project does not, however, include the command-line version.

Usage

The command-line version of Jazmin reads the source from the standard input and produces the compressed version on the standard output. To compress a single file, pipe through Jazmin like this on Windows Command Prompt:

$ type some.js | jazmin > comp\some.js

To source-compress several files in a single run, consider using FOR like this:

$ for %i in (*.js) do type %i | jazmin > comp\%i

Requirements

The command-line tool requires Microsoft .NET Framework 1.1 to run and supports the same set of operating systems as the runtime.
The MSBuild task requires Microsoft .NET Framework 2.0 to run and supports the same set of operating systems as the runtime.
