Using CSS Custom Properties for better UX in Frontend and Gutenberg

September 30, 2019

It’s been a while since I have posted on my blog. In fact almost 2 years now. But it’s been even longer since I have significantly touched the foundation of my website; other than the regular updates, adding a small plugin here or there, my website had been using the same infrastructure and theme since 2019. A lot of it even already existed the same way in 2018. My website had gotten really out of date, in terms of both content and technology. Some of the blocks I had implemented years ago were no longer working, so part of me was even afraid to open the block editor.

A few weeks ago, I finally decided to change that and modernize my website. But it didn’t just came out of nowhere. Specifically, I wanted to update my website to use a block theme. I had been excited about them since they were in the exploration stage already in 2019, pretty much as far back as when I was rebuilding my website, “the old way”. The opportunities for enhancing performance due to the new block theme paradigm seemed extremely promising to me.

Now that we’ve already had 3 major WordPress releases to establish and refine the new infrastructure, I decided to really give it a try. In this post I’ll share my experiences with you as well as the outcome and how it is impacting performance.

Native Lazy-Loading for WordPress

September 5, 2019

A few weeks ago, it was announced that Google Chrome started supporting the new loading attribute, which allows websites to have their images and iframes lazy-loaded without any custom JavaScript. Support for the feature will most likely be extended to further browsers soon, but you can already use it today without any negative impact for browsers where it isn’t supported yet.

If you have a WordPress site, our team at Google has just released a new plugin “Native Lazyload” which you can install, activate, and your site will support native lazy-loading instantly.

Customizing Google Analytics Configuration in the Site Kit Plugin

August 15, 2019

The Site Kit plugin by Google makes it trivial to integrate your WordPress site with various publisher-facing Google services such as Google Analytics. In addition to exposing key insights from these services directly in your WordPress dashboard, it also automatically places the necessary code snippets on your page to ensure these metrics can be gathered properly.

In this post we will look at Google Analytics specifically and how you can customize its behavior in the Site Kit plugin. While the default configuration already gives you access to many valuable metrics, Google Analytics becomes really powerful when you have tailored it to your specific use-cases. With Site Kit currently still in Beta, the user-facing configuration options for Google Analytics are minimal. While we are exploring how we can expose more customization opportunities through the plugin’s settings UI, it may be a while until these improvements are included in a new plugin’s release. Since its beta 1.0.4 release though, the plugin includes filters to modify the Google Analytics configuration, so as a developer you can tweak it in almost any way you like already today.

Exploring Sitewide Gutenberg Usage Today

July 10, 2019

Phase 2 of Gutenberg is all about taking the compelling capabilities of the block editor to the site level. WordPress 5.0 introduced it as the new editor for post content, but that was only the beginning. Blocks are a powerful tool and inspired by the learnings of various other formats of editing that WordPress and other platforms have been using over the years, so it makes sense for them to provide a unified approach to reusable content. The difference between shortcodes and widgets for example has pretty much been non-existent, and it felt weird to create a certain UI component only for one of the two, or having to write some duplicate code to address both layers. With Gutenberg being expanded to become the editor for your entire WordPress site, beyond the post content bubble, this problem will be solved. Furthermore, it will bring the new editor much closer to being able to fully compete with existing layout builders.

Each of the steps to get there (e.g. migrating widgets, menus, and possibly even other elements fully controlled by the theme today) poses several challenges, so it might still be some time until we get to experience all this functionality in its proper implementation. Therefore, inspired by a conversation with Morten at WordCamp Europe a few weeks ago, I wrote a tiny experimental plugin that allows you to use blocks on a sitewide level and explore what the theming of tomorrow could look like already today.

Leveraging the Power of Custom Elements in Gutenberg

July 3, 2019

This is essentially a written version of the talk of the same name that I gave at WordCamp Europe 2019 (see the related slide deck).

As I’m sure we can all confirm, WordPress provides a strong toolset for creating awesome content. Particularly with the availability of the Gutenberg editor, publishers can now implement more interesting layouts and take their content quality to the next level. However, while the content itself is certainly the most important part of a website, there are a few other supporting pillars to ensure delightful content experiences for users consuming that content. Websites should be:

For more details on these four pillars, see the “Progressive WordPress Themes” talk by my colleagues Alberto Medina and Thierry Muller.

Unfortunately, satisfying each of these four requirements is anything but trivial. You might already know that just installing a performance or a security plugin is not actually going to magically solve these respective points.

Technologies and best practices on the web are constantly evolving: Regularly new APIs are introduced, new standards being established, former best practices being overruled. Add in all the popular frameworks that have come and gone over the years, and it becomes even more evident: Even the most senior rockstar full-stack developer cannot keep up with this technology complexity on their own.

In addition, even in the scope of a single website or application, maintaining a good overview of the different pieces can present a huge cognitive challenge. HTML, CSS, JavaScript, code for different areas shed across everywhere, with possible incompatibilities in functionality as well as in appearance with all thiese pieces being used in combination. This is what we can refer to as content complexity.

Fortunately, there are ways to reduce and work around both of these complexities. In this post we will look at a component-based approach and a relatively new technology called “Custom Elements” and how they address the aforementioned problems.
