I think it's worth sharing the progress of my lottie compiler here: github.com/cometkim/ulo... You can test it on the demo page, which now has a live output preview in the breakdown section.

I'm going through a backlog of ~220 links to Design Systems things for the newsletter before the #HungarianGP. Seems I've written quite a bit since the last newsletter was sent out :lolsob: You can sign up to get the emails and check past issues here: https://news.design.systems 🙏🖤

Another great post by @joshwcomeau.com. I love that he didn't try to cover the whole API, but made a pragmatic decision to explain the most useful bits. As always, I learned a lot from this post. www.joshwcomeau.com/css/anchor-p... #css

If you make websites for a living, stop what you're doing and read this research by @tammyeverts.com; it shows what many of us have been saying for a long time: even if there is such a thing as "fast enough", it's generally *much* faster than you are targeting: embrace.io/blog/research-co…

If you are on the latest pnpm v11.10.0 (or v10.34.5), you can try out the pnpm v12 alpha via: pnpm self-update 12.0.0-alpha.5 It is fully in Rust! 🦀

Playing with `focusgroup` support in Chrome 150 and I like seeing the browser assign role based on the `focusgroup` token. Yes, you can override with explicit `role`, which will undoubtedly happen as devs choose kbd patterns that don’t match the role. But still neat. codepen.io/aardrian/pen...

Does your design system have a rulebook? Not just what was decided but why, and what was rejected. With AI working inside design systems, undocumented reasoning is a gap the model will fill on its own. Great piece by Kevin Muldoon on the three kinds of truth every system needs: hubs.li/Q04f6BFv0

npm increasingly feels like a zombie org under GitHub. As someone who's been around the JS ecosystem and part of multiple OSS orgs for years, what I'm seeing isn't just "big co moves slow." It's quiet neglect of critical infrastructure the entire JS world runs on. A short thread 🧵
