Now I’m using YUI Compressor for my project and when I decided to make an experiment with Googles’ software it was just because I’d like to gain loading savings. In the project I’m working on I use two famous JavaScript libraries: jQuery and OpenLayers, and the result was really good. The compiled code was smaller than the YUI compressed source and the savings where more than 50% for non-gzipped requests.

The problem is that the resulting code, even successfully compiled after what Google said, was producing errors on the site and wasn’t working correctly. That why I’m leaving the title as a question and I’ll continue my experiments with this approach until I get any good results.

Giving an extream power to use the user interface on it’s limits, with functionalities as drag and drop, resize, select, sort, etc.

This subset of the JQuery library can be used with very small code includes, and that makes the ease of use even more. Actually I think that library is really more easy to use than any other as SPRY, YUI, etc.

I recommend it!
