Developing things on the web. Web performance engineer at Automattic. Clumsy maker.
It's been a while since my last blog post, so I made up for it with a wall of text 😅
This article looks at why JS-heavy web apps tend to miss their performance goals over time, what you can do to somewhat mitigate that, and ends with a plea for us to move back to the server, as an industry.

During the installation process, package managers run a bunch of semver comparisons. The semver library used in npm, yarn and pnpm can be made around 33x faster.
