Project Description

Bundle Transformer - a modular extension for System.Web.Optimization (also known as the Microsoft ASP.NET Web Optimization Framework). Classes StyleTransformer and ScriptTransformer, included in the core of Bundle Transformer and implement interface IBundleTransform. They are intended to replace the standard classes CssMinify and JsMinify.

The main differences of StyleTransformer and ScriptTransformer classes from a standard implementations: ability to exclude unnecessary assets when adding assets from a directory, does not produce the re-minification of pre-minified assets, support automatic transformation of relative paths to absolute in CSS-code (by using UrlRewritingCssPostProcessor), etc. These classes do not produce the minification of code in runtime, but this feature can be added by installing of minifier-modules (now available modules based on Microsoft Ajax Minifier, YUI Compressor for .NET, Google Closure Compiler, Douglas Crockford's JSMin, Dean Edwards' Packer, Mihai Bazon's UglifyJS, Sergey Kryzhanovsky's CSSO (CSS Optimizer), WebGrease and Clean-css). In addition, you can also install translator-modules that implement the translation of code on intermediate languages (LESS, Sass, SCSS, CoffeeScript, TypeScript, Mustache (by using Hogan) and Handlebars). Apart from this, in the Bundle Transformer there is a third type of modules - postprocessors. Postprocessors runs after translators and before minifiers. Now available following postprocessors: URL rewriting CSS-postprocessor (included in core) and postprocessor-module based on the Andrey Sitnik's Autoprefixer.

This extension will help your web applications successfully pass a most part of the tests in YSlow.
