UglifyJS - Taritsyn/BundleTransformer GitHub Wiki

BundleTransformer.UglifyJs contains one minifier-adapter for minification of JS code - UglifyJsMinifier. UglifyJsMinifier is based on the Mihai Bazon's UglifyJS version 2.8.29.

As a JS engine is used the JavaScript Engine Switcher library. For correct working of this module, you need to install one of the following NuGet packages:

• JavaScriptEngineSwitcher.ChakraCore
• JavaScriptEngineSwitcher.Jint
• JavaScriptEngineSwitcher.Msie (only in the Chakra modes)
• JavaScriptEngineSwitcher.V8

After package is installed and JS engine is registered, need set a name of JS engine (for example, MsieJsEngine) to the name attribute of /configuration/bundleTransformer/uglify/jsEngine configuration element in the Web.config file.

To make UglifyJsMinifier is the default JS minifier, you need to make changes to the Web.config file. In the defaultMinifier attribute of /configuration/bundleTransformer/core/js element must be set value equal to UglifyJsMinifier.
