We've merged and released an initial turbopack support for next-yak 🎉🎉
All features work out of the box aside from imports in .yak.ts files.
It also tackles long standing issues and should work generally better than the webpack version.

If you don't see this, you're limiting the experience of your users.
Understandable. In the end what matters is that a static CSS file served with a hashed filename and `Cache-Control: Immutable` is served to end users, with the only remaining runtime logic being what `className` attributes to use to decide styling, and the occasional custom property override 💖

Type stripping is enabled by default 🔥🔥🔥🔥
You can just run `node file.ts` without `--experimental-strip-types` flag.
This is a huge milestone

Node.js 22.18.0 is out and enables type stripping by default – that’s right, Node.js LTS can now run TypeScript files. Shout out to @marcoippolito.dev for championing that effort! Download links and full changelog available at nodejs.org/en/blog/rele...
Node.js — Node.js v22.18.0 (LTS)
Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts.

If you find an OSS issue that calls your attention, go for it. You don't need to ask permission to start working or have it assigned to you. If someone else sends a PR before you, that's great. You can use your knowledge of the issue to help review the PR, add tests, and validate the approach.

I went from RSC lover to RSC sceptic and today as I'm unsure what to think of it, this incredible post dropped. I like it way better than the first post of dan, but I'm still not sure if the benefits of RSCs outweight the costs in all cases. The complexity and also the number of bugs is just huge.

Styled components has officially moved into maintenance-only mode: https://opencollective.com/styled-components/updates/thank-you
That's the bell I think, the era of runtime css-in-js libraries is now definitively over. So long and thanks for all the divs.

We've migrated from styled-components to next-yak at our company (galaxus.ch) and we saw ~12% decrease in INP and ~15-20% decrease in LCP due to better latency on the server. Build times didn't go up drastically and moving forward we bet fully on it.

I got it working 🥳 Had to specify explicitely that my swc plugin (wasm) should be included. The loading of the wasm is super slow (~10s), but I'm happy that it runs. Next up: optimize the loading time. @kdy1.bsky.social any hints?
Maybe I have more luck here 😅:
Does anybody have some experience running SWC as a standalone tool in a vercel function? I want to provide a playground for our SWC plugin, but that has to run on the server. It runs perfectly fine locally, but vercel has some issues with path mapping and binary sizes
