In my audits, reading the Performance profile is where people get stuck: the flame chart and waterfall look like noise at first I built an interactive guide to make them click, every figure is interactive, plus LCP, CLS, INP and the Insights panel perf.reviews/profile-guide #WebPerf #DevTools

An interactive field guide to the Chrome DevTools Performance panel: waterfall, flame chart, LCP, CLS, INP, and the Insights panel.

My second ever application to a conference got accepted 🎉 I'm beyond words, how much I'm looking forward to this. Presenting about a topic I care about and connecting with new people is always something I love to do 🎡

Really nice spin on the RSC concept with client-first. This way the mental model of developers can still be useful, even in the RSC era. I see why others didn't do that, as composition is a bit harder and doesn't feel as natural compared to the server-first approach. I'm looking forward to try it.

Finally, TanStack Start now supports React Server Components! Start's RSCs are a truly fetchable, cacheable and composable primitive that work with your favorite tools instead of dictating your entire architecture. Oh, and one more thing... "Composite Components" 😉 tanstack.com/blog/react-s...

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.

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...

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.
