Reviews

Must have. Handles JS better than WP Rocket does alone.

Been a loyal WP Rocket user for years, and full JS optimization (minify/concat) has always been a thorny issue because it broke more sites than it worked on. (Disclaimer: this is, of course, without taking a lot of time to troubleshoot and exclude individual JS files from optimization, but who has the time for that?)

Even with the latest 2.10.4, WP Rocket has some trouble with this. However, dropping this plugin in and THEN activating Rocket’s JS minification works like a charm.

Please note that this plugin requires you to activate JS optimizations in WP Rocket in order to work. It basically takes over Rocket’s logic, and seems to do a better job of it.
