How to obfuscate/compress javascript on the fly?

Question

Data compression

CMS Prestashop in php, Smarty templating engine.
For Smarty, there is a smarty_outputfilter_trimwhitespace plugin, it compresses HTML, but does not touch Javascript.
I would like to do the same for JS, but there was no direct solution. Advise?

Yes, it seems to compress:
If the scripts are connected separately, then just use the compressed version, for example, I use netbeans and the plugin plugins.netbeans.org/plugin/49666/js-css-minify-co...

Answer 2

Have you tried Grunt/Gulp?
