Developers: don’t make Gutenberg go Badass-enberg on my frontend!

Over the past couple of months, since the release of WordPress 5.0 which includes Gutenberg, the new JavaScript-based block editor, I have seen many sites loading a significant amount of extra JavaScript from wp-includes/js/dist on the frontend due to plugins doing it wrong.

So dear plugin-developer-friends; when adding Gutenberg blocks please differentiate between editor access and visitor access, only enqueue JS/ CSS if needed to display your blocks and when registering for front-end please please frigging please don’t declare wp-blocks, wp-element, … and all of those other editor goodies as dependencies unless your 100% sure this is needed (which will almost never be the case).

The performance optimization crowd will thank you for being considerate and -more likely- will curse you if you are not!

Autoptimize 2.5 almost ready, last call for testers!

Autoptimize 2.5 is almost ready! It features a new “Images”-tab to house all Image optimization options, including support for lazy-loading images and WebP (the only next-gen image format that really matters, no?);

So download the beta and test lazy-loading and WebP (and all of the other changes) and let me know of any issue you might find!

Google PageSpeed Insights; the great Defer unused CSS mystery to be resolved?

You know that frustrating Google PageSpeed Insights opportunity “Defer unused CSS”? Well, it’s going to be renamed soon (in Lighthouse first, so GPSI should follow) as per this Github merged pull request;

The full text will read;

Remove unused CSS
Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity.

WP YouTube Lyte: 20K active installs and a new release

It took a lot of time for WP YouTube Lyte to get there, but we finally got to 20 000 active installs, and to celebrate that occasion I release a long overdue update (1.7.6), with the following improvements;

  • extra parameters for shortcode (start, showinfo, stepsize and hqthumb).
  • also turn youtube-nocookie.com iframes into LYTE’s as proposed by Maxim.
  • also remove cached thumbnails when clearing cache.
  • also set image in noscript tag to local hosted thumbnail if that option is active.

And in case you’re wonder, this how a LYTE video looks like;

Autoptimize 2.5 beta: image lazy loading

2018 is end of life and 2019 will be released soon. Autoptimize 2.5 is not at that point yet, but I just pushed a version to GitHub which adds image lazy loading to Autoptimize;

The actual lazy-loading is implemented by the integrated lazysizes JS lazy loader which has a lot of options some of which I will experiment with and bring to Autoptimize to the default improve user experience.

If you want you can download the beta (2.5.0-beta2) now from Github (disable 2.4.4 before activating the beta) and start using the new functionality immediately. And if you have feedback; shoot, I’ll be happy to take your remarks with me to bring AO 2.5 ready for release (I’m targeting March, but we’ll see).

Enjoy the celebrations and have a great 2019!
