From the guy that also brought us this, but also this.
Tom Vek is an English multi-instrumentalist, but you could just as well read the Wikipedia-article if you want to know that and more. If, instead, you’d prefer to hear what he sounds like, you can listen (and watch) below video of “Sherman (Animals in the Jungle)”;
Autoptimize comes with a “Add try-catch wrapping?”-option, which wraps every aggregated script in a try-catch-block, to avoid an error in one script to block the others.
I considered enabling this option by default, as it would prevent JS optimization occasionally breaking sites badly. I discussed this with a number of smart people and searched the web, eventually stumbling on this blogpost which offers an alternative for try-catch because;
So given this damning evidence of severe performance degradation, “try/catch wrapping” will not be enabled by default and although Ryan’s alternative approach has its merits, I’m weary of the caveats so I won’t include that (for now anyway). If your site breaks when enabling JS optimization in Autoptimize, you can enable try/catch wrapping as a quick workaround, but finding the offending script and excluding it from being optimized is clearly the better solution.

Especially love the acoustic version of Flying Lotus’ “Tea Leaf Dancers” at the 27th minute!
Although current versions of Autoptimize can already tackle Google PageSpeed Insights’ “Eliminate render-blocking CSS in above-the-fold content” tip, the next release will allow you to do so in an even better way. As from version 1.9 you’ll be able to combine the best of both “inline CSS” and “defer CSS” worlds. “Defer” effectively becomes “Inline and defer“, allowing you to specify the “above the fold CSS” which is then inlined in the head of your HTML, while your normal autoptimized CSS is deferred until the page has finished loading.
Other improvements in the upcoming Autoptimize 1.9.0 include:
- Inlined Base64-encoded background Images will now be cached as well and the threshold for inlining these images has been bumped up to 4096 bytes (from 2560).
- Separate cache-directories for CSS and JS in /wp-content/cache/autoptimize, which should result in faster cache pruning (and in some cases possibly faster serving of individual aggregated files).
- CSS is now added before the
-tag, JS before
