Adobe Experience Manager Sites & More

Hello, everyone!

I'm trying to change the JS compiler from Yui to GCC (to use ES6 in our project), I have read the official document ( Change the minification engine for client libraries in AEM ), but for some reason the GCC is not working.

What we have tried:

Changing in http://localhost:4502/system/console/configMgr -> Adobe Granite HTML Library Manager -> JS Processor Default Configs -> Change min:yui to min:gcc (and tried with min:gcc;languageIn=ECMASCRIPT6).

This doesn't work.

Adding the jsProcessor inside the clientLibraryFolder like this:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
    jcr:primaryType="cq:ClientLibraryFolder"
    allowProxy="{Boolean}true"
    embed="[project.components]"
    categories="project.all"
    jsProcessor="[default:none,min:gcc;languageIn=ECMASCRIPT6]"/>

This doesn't work either.

If we turn it back to min:yui on the configMgr, it works again, but just minfies the ES5 functions, if we use arrow functions or let/const, it doesn't transform into ES5 (the main reason why we're changing to GCC).

Could you guys please help us?

Thank you!

Cust Care found a ticket related to this and says this doc not valid for 6.4. I recommend opening a ticket so this can be dealt with.

Hi there,

I set up an OSGI config file called com.adobe.granite.ui.clientlibs.impl.HtmlLibraryManagerImpl.xml with these contents and gcc seems to work o.k.
for JS with some caveats.
I still get some files failing minification because of "strict" errors which I couldn't seem to get around with configuration options in this file.
In the end, I had to fix the errors in the files to get the gcc to minimize them.
