Change the minification engine for client libraries in AEM
This article addresses the Adobe Experience Manager issue where you want use a different minification library for AEM client libraries other than the default YUI Compressor library. You may use the Google Closure Compiler (GCC); see through the client library nodes that use GCC for JS below.

Issue/Symptoms
How to use a different minification library for AEM client libraries than the default YUI Compressor library?
Resolution resolution
In AEM, you can swap out the YUI engine with GCC (Google Closure Compiler https://github.com/google/closure-compiler-js).
For example, see these client library nodes that use GCC for JS:
/libs/granite/contexthub/dependencies/coralui
/etc/clientlibs/granite/coralui3
/etc/clientlibs/granite/coralui2
/libs/dam/gui/coral/components/admin/adhocassetshare/clientlibs/adhocassetshare
/libs/dam/gui/components/admin/adhocassetshare/clientlibs/shareembedded
/etc/clientlibs/screens/player/shared
/etc/clientlibs/screens/player/firmware
/libs/dam/gui/components/admin/adhocassetshare/clientlibs/shareembeddedpreview
/apps/geometrixx-instore/clientlibs
Note: If you want to implement your own custom script processor, then you would implement this Java interface:com.adobe.granite.ui.clientlibs.script.ScriptProcessor
RELATED JAVADOC:
This allows you to define ScriptProcessors that can modify script sources:
- the processors are configurable with options
- the processor can be used for minification but also for non-minified cases
CONFIGURATION:
- The default
ScriptProcessorsoptions can be set via the HTML Library Manager OSGi configuration (in the/system/console/configMgrUI).
OPTIONS FOR GCC ARE:
failOnWarning(defaults to false)languageIn(defaults to ECMASCRIPT5)languageOut(defaults to ECMASCRIPT5)compilationLevel(defaults to simple) (can be whitespace, simple, advanced)
