Web Performance News, July 2020

Google released a statement about updates to its search ranking. It all goes back to Core Web Vitals and how they affect user experience. The other thing to note you won’t need the AMP version of your page to be featured in mobile’s search “Top Stories” feature which is a step forward in my mind!

We covered Core Web Vitals last time, and it’s getting more popular with more tooling becoming available. There is a Chrome plugin now that could give you instant scores for the page. There is also a new article about how you can measure core web vitals for your site right now.

@dev_starikov wrote an impressive piece on CSS animations and how some time you’d need to decide between visual and performance.

@DebugBear did fantastic research on Chrome Extensions and how they contribute to the Web performance. Have a look and think of replacing the slow ones! What I also found is you could disable auto load for some of the extensions, so you would need to click on it to activate it. For instance, I could do that for LastPass.

Apple released a beta version of Safari 14 with some significant features added. For me, WebP and HTTP/3 support are the most remarkable. But there are many more here.

Houssein Djirdeh made an outstanding web app called “Perf Track”, which shows how different web frameworks perform. The app could be a great input for your new project when you can’t decide what framework to use :)

Native images lazy loading gets some improvements in the latest Chrome release. So far we were still recommending using intersection observer with JS for lazy loading but looks like this is going to change soon.

Stay safe, Pixboost Team.
