In AEM6.2 and later versions, you can set properties on cq:ClientLibraryFolder nodes that let you swap out yui engine with GCC (Google Clojure Compiler https://github.com/google/closure-compiler-js).
For example, see these client library nodes that use GCC for js:
In addition, if you want to implement your own custom script processor, then you would implement this java interface:
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
- a property on the cq:ClientLibraryFolder node allows you to define which processor to use
- These extra multivalue properties can be set on the cq:ClientLibraryFolder node: cssProcessor and jsProcessor.
- The default ScriptProcessors options can be set via the HTML Library Manager OSGi configuration (in the /system/console/configMgr UI).
For example, to use YUI compressor for css minification and Google Closure Compiler for JS set these properties on the cq:ClientLibraryFolder node:
cssProcessor: ["default:none", "min:yui"]
jsProcessor: ["default:none", "min:gcc;compilationLevel=advanced"]
use typescript to preprocess, then gcc to minify and obfuscate:
the format is:
config:= mode ":" processorName options*;
mode:= "default" | "min";
processorName := "none" | ;
options := ";" option;
option := name "=" value;
