Packer

BundleTransformer.Packer contains one minifier-adapter for minification of JS code - EdwardsJsMinifier. EdwardsJsMinifier is based on the Dean Edwards' Packer version 3.0.

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
• 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/packer/jsEngine configuration element in the Web.config file.

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