Project Description

BundlingTweaks plugs into the Bundling/Minification pipeline in ASP.NET MVC 4 Beta and tries to find non-minimized JS and CSS files while bundling so you can see the actual, non-minified, JavaScript and CSS you wrote in the first place.

This only happens during debugging (using an #if DEBUG in the startup code), so you don't have to worry about compromising your release code's minification.

BundlingTweaks tries 2 things to find replacements for any ".js/.css"file:
  • Remove ".min"
  • Add ".debug"
(e.g. "Foo.min.css" => "Foo.css", "Bar.js" => "Bar.debug.js")


If you so desire, you can add other custom replacements, like ".release" -> ".debug" by adding them to a static dictionary:

TweakSettings.ExtensionReplacements.Add(".minified", string.Empty);
TweakSettings.ExtensionReplacements.Add(string.Empty, ".pretty");
TweakSettings.ExtensionReplacements.Add(".release, ".debug");


You can also enable Trace output like this:
TweakSettings.EnableTraceOutput = true;
