AEM 6.4/ AEM 6.5 Clientlib specific Preprocessors

AEM allows for pluggable preprocessors and ships with support for YUI Compressor for CSS and JavaScript and Google Closure Compiler (GCC) for JavaScript with YUI set as AEM's default preprocessor.

By default, AEM uses the YUI Compressor. Switching to GCC compressor for particular clientlibs may solve some issues observed when using YUI.

You can choose to configure the preprocessors configuration per client library or system-wide.

• Add the multivalue properties cssProcessor and jsProcessor on the clientlibrary node
• Or define the system default configuration via the HTML Library Manager OSGi configuration

A preprocessor configuration on the clientlib node takes precedence over the OSGI configuration.

cssProcessor: ["default:none", "min:yui"]
jsProcessor: ["default:none", "min:gcc;compilationLevel=advanced"]
