Impressive, comprehensive

I’ll start by saying I initially passed over this plugin due to the sort of odd name—felt a bit over-specific.

But eventually I was searching to replace Mozilla’s abandoned Offline Content plugin and noticed this plugin includes a Service Worker…lo and behold it actually covers almost every major aspect of performance tuning for a site! It minifies, it defers and async loads javascript and CSS, it has a Service Worker and even HTTP/2 Push events.

This is the best ServiceWorker plugin I’ve found and honestly the only one that really properly allows me to do what I need to make a proper offline-ready app that caches my most popular content. If you want your site to have an App-style UX on mobile I strongly recommend this.

In addition, I found it better than Autoptimize (which I uninstalled) since it defers Javascript and CSS in a way that leaves filenames intact, which is more cache-friendly since with autoptimize pages may use a separate “bundled” CSS/js that havent’ been cached by my ServiceWorker.

Regarding the 1 star reviews, yes, this IS a plugin that will break your site if you use it wrong; this is an advanced plugin that, necessarily, alters how your site distributes critical resources. You should have a good understanding of what you’re doing and be able to dedicate a little time to get things absolutely right if you’re going to use this.
