There were some big announcements and updates in May. Let’s dive into it!
The new major version of Lighthouse has been released. TADAAM! Lighthouse is one of the most popular tools to measure web performance. In the link above you’ll find what’s changed and why the score is different now. There is also a new version of Lighthouse CI available and we updated the docker image that we use to run tests continuously on pixboost.com.
Google did a GOODle and released a new set of metrics that impacts users the most. They called them Web Vitals. The core set includes just 3 items that you are measuring on the real users opposed to synthetic metrics from tools like Lighthouse. I really love an idea of simplifying the web performance and making it accessible for everyone: “Site owners should not have to be performance gurus in order to understand the quality of experience they are delivering to their users. The Web Vitals initiative aims to simplify the landscape, and help sites focus on the metrics that matter most, the Core Web Vitals.”. If you are interested in the story behind the metrics then you’ll find this link interesting.
@hdjirdeh and @addyosmani wrote about optimising First Input Delay (FID) metric. Worth to mention that it’s one of the metrics from Core Web Vitals. You’ll find good advice on how to tame JS execution on your web pages.
Chromium launched a new way of blocking ads that consumes too much resources on your device. This will eventually land on Chrome around August. I think this is a good step forward to make the Internet a better place.
That’s it for today. Stay safe and load fast!
