Tips and News from the World of Speed vol. 2

This time, we will delve into the world of Next.js and evaluate HTTP/3. The folks at Wolt have devised a plugin called BlurHash, so we will dissect its usefulness and mark the month of May in red for next year.

Next.js conf#

At the Next.js conference, the new version 10 of this popular React framework was unveiled, bringing several intriguing updates. The first of these are custom performance metrics, collectively referred to as RES - real experience score.

The second significant update is the Image component, designed to address all common image-related issues. On the flip side, developers criticize it as a “black box” without control. We delve into the details in the video below.

HTTP/3#

Google has implemented the third version of the protocol powering our websites. Data throughput and latency are expected to improve. Conversely, there's been a shift away from resource prioritization.

BlurHash#

If, like the designers at Wolt, you're tired of dull grey loading screens, you might want to try their latest BlurHash plugin. However, be mindful of the overall decoding time BlurHash consumes.

Core Web Vitals as a Search Ranking Parameter#

May 2021 should be carefully marked in our diaries. Google announced that from this date, it will incorporate Core Web Vitals as a parameter for search ranking. Developers thus have the last six months to fine-tune website speed.

We thoroughly discussed all these topics in our livestream "Speed Matters", from which we bring you an edited recording.
