asp.net mvc - Javascript bundle obfuscation and Bundletransformer -

i trying obfuscate output of our javascript bundles on fly , came across bundletransformer (a bundling extension uses yui compressor), had no success implementing it! far reading provided documentation i've written following code in registerbundles method:

        var nullbuilder = new nullbuilder();                    var csstransformer = new csstransformer();          var yuisettings = new bundletransformer.yui.configuration.yuisettings();         yuisettings.jsminifier.obfuscatejavascript = true;          var jstransformer = new jstransformer();          var nullorderer = new nullorderer();          var scriptbundle = new customscriptbundle("~/jscbundle/").include(                       "~/assets/scripts/jquery.js",                       "~/assets/scripts/jquery-ui.js");          scriptbundle.builder = nullbuilder;         scriptbundle.orderer = nullorderer;           scriptbundle.transforms.add(jstransformer);          bundles.add(scriptbundle); 

and following code in web.config :

<bundletransformer xmlns="http://tempuri.org/bundletransformer.configuration.xsd"> <core>   <css>     <minifiers>       <add name="nullminifier" type="bundletransformer.core.minifiers.nullminifier, bundletransformer.core" />       <add name="yuicssminifier" type="bundletransformer.yui.minifiers.yuicssminifier, bundletransformer.yui"  />     </minifiers>     <translators>       <add name="nulltranslator" type="bundletransformer.core.translators.nulltranslator, bundletransformer.core" enabled="false" />     </translators>   </css>   <js defaultminifier="yuijsminifier" usepreminifiedfiles="true">     <minifiers>       <add name="nullminifier" type="bundletransformer.core.minifiers.nullminifier, bundletransformer.core" />       <add name="yuijsminifier" type="bundletransformer.yui.minifiers.yuijsminifier, bundletransformer.yui" />     </minifiers>     <translators>       <add name="nulltranslator" type="bundletransformer.core.translators.nulltranslator, bundletransformer.core" enabled="false" />     </translators>   </js> </core> <yui>   <css compressiontype="standard" removecomments="true" linebreakposition="-1" />   <js compressiontype="standard" obfuscatejavascript="true" preserveallsemicolons="false" disableoptimizations="false" ignoreeval="false" severity="0" linebreakposition="-1" encoding="utf8" threadculture="en-us" /> </yui> 

judging bundle output can infer not it's not obfuscated compression not taking effect @ all! not find samples online , tried changing few settings here , there no luck! i'm pretty clueless , solutions or suggestions appreciated. in advance!

bahador,

actually, need simple code:

namespace testyui {     using system.web.optimization;      using bundletransformer.core.bundles;     using bundletransformer.core.orderers;      public class bundleconfig     {         public static void registerbundles(bundlecollection bundles)         {             var nullorderer = new nullorderer();              var scriptbundle = new customscriptbundle("~/jscbundle/");             scriptbundle.include(                 "~/assets/scripts/jquery.js",                 "~/assets/scripts/jquery-ui.js");             scriptbundle.orderer = nullorderer;              bundles.add(scriptbundle);         }     } } 

and settings in web.config file:

<configuration>     …     <bundletransformer xmlns="http://tempuri.org/bundletransformer.configuration.xsd">         <core>             <css>                 <minifiers>                     <add name="nullminifier" type="bundletransformer.core.minifiers.nullminifier, bundletransformer.core" />                     <add name="yuicssminifier" type="bundletransformer.yui.minifiers.yuicssminifier, bundletransformer.yui" />                 </minifiers>                 <translators>                     <add name="nulltranslator" type="bundletransformer.core.translators.nulltranslator, bundletransformer.core" enabled="false" />                 </translators>             </css>             <js defaultminifier="yuijsminifier">                 <minifiers>                     <add name="nullminifier" type="bundletransformer.core.minifiers.nullminifier, bundletransformer.core" />                     <add name="yuijsminifier" type="bundletransformer.yui.minifiers.yuijsminifier, bundletransformer.yui" />                 </minifiers>                 <translators>                     <add name="nulltranslator" type="bundletransformer.core.translators.nulltranslator, bundletransformer.core" enabled="false" />                 </translators>             </js>         </core>     </bundletransformer>     … </configuration> 

rather, problem caused fact, web application run in debug mode.

switch web application release mode using following settings in web.config file:

<configuration>   …   <system.web>     <compilation debug="false"  … />     …   </system.web>   … </configuration> 

or add app_start\bundleconfig.cs file following code:

bundletable.enableoptimizations = true; 

before read documentation bundle transformer, recommend read chapter “bundling , minification” of asp.net mvc 4 tutorial.
