Wrote an article about how React Server Components integrate with a bundler. It's a deep dive into how code splitting works, how RSCs eliminate network waterfalls, how environment directives like "use client" work, CSS loading, etc. Check it out! devongovett.me/blog/parcel-...

perf: memorize exclude function in webpack config by SyMind · Pull Request #81525 · vercel/next.js During JavaScript profiling, I identified repeated calls to the exclude function in the webpack configuration and implemented caching to optimize it. I tested the performance using the chakra-ui-d...

An awesome contribution for those still stuck on webpack.

Next.js 15.4 Next.js 15.4 includes updates to performance, stability, and Turbopack compatibility.

Next.js 15.4

• Turbopack Builds: 100% integration test compatibility for next build --turbopack
• General stability and performance improvements
• A preview of what's coming in Next 16

nextjs.org/blog/next-15-4

Over the past two months, next-rspack has become more stable and now passes 98% of the next build integration tests. After reaching 100%, we will focus on improving its performance.

Yikes. One major difference between Turbopack and webpack is that Turbopack uses a stricter parser (lightningcss) that errors on broken css that would be silently ignored in webpack.

The new behavior is better, but the migration can be painful.

I'd love to hear if you figure out the issue here.

I ran cargo-shear on Turbopack's codebase. It worked really well! github.com/vercel/next....

Thanks for creating such an awesome little tool, @boshen.github.io!

Help wanted: An engineering manager who can tolerate my antics during stand-up.

If you love devtools, performance, and want to help us roll our Turbopack everywhere, please apply or reach out!

You're right. We don't recommend it for anything mission-critical yet, but we also want to get some feedback from early adopters. We've been using it for internal tools where client performance or SEO isn't critical.

Turbopack for Dev workflows is stable, and we do recommend that you try that out!

I made a website. It's called "one million chessboards." It has a million chessboards on it.

moving a piece moves it for everyone, instantly. No turns. You can move between boards.

that's it. Have fun!

Happy Easter!

Excited to bring you the first version of "next build --turbopack"!

Looking forward to seeing the results and iterating quickly towards stability. If you have feedback, let us know!

Rspack v1.2.7 is out!

🚀 up to 20% faster on macOS
🚀 20% less HMR memory usage
🐛 14 bug fixes

Compared to Next.js 15.1 (just a few months ago) we've seen customers report that the latest version of Turbopack is up to 57.6% faster. And it consumes about 30% less memory.

The whole team spent many weeks focused on profiling and finding tons of incremental wins!

Turbopack is incredible - just tested out the latest Next.js canary in the @payload.dev monorepo and our compile times + memory usage have improved significantly:

Webpack Postgres: Out-Of-Memory
Turbo Postgres: 5.4s

Webpack Mongo: 19.3s
Turbo Mongo: 6.3s

That's a 3x speed improvement 🎉

`sonda` just hit 10k weekly downloads on npm! Huge thanks to everyone using it and supporting the project 🙏

If you haven’t tried it yet and want to see what’s inside your JS & CSS bundles, check it out here: sonda.dev

👀
Now try the Next.js 15.2 Canary release... It's even faster!

@kdy1.bsky.social is the 🐐! This makes all bundlers using SWC that much faster, so the ecosystem impact is huge!

If you don't like ghostty, iTerm is always a solid option. It uses native widgets (like ghostty). It's faster and has more features than the default app.

The built-in terminal app is very slow to support new features (e.g. 24 bit color, synchronized output to prevent tearing, extended underlines, sixel for graphics/images) and tends to be buggy creating a support burden for TUIs trying to support it (e.g. github.com/neovim/neovi...).

[Turbopack] Implement support for webpack’s `stats.json` by wbinnssmith · Pull Request #70996 · vercel/next.js This allows bundle analyzer tools to visualize and explore the output of Next.js apps built with Turbopack.

Turbopack does have experimental/undocumented support for the webpack stats.json format: github.com/vercel/next....

It doesn't make much sense to use yet as we still don't support production builds with Turbopack. Right now we're just using it to debug our own work towards production builds.

Turbopack Dev is Now Stable It's been a long road, but we are happy to announce that `next dev --turbo` is now stable and ready to speed up your development experience.

It's not on by default because we don't support production builds yet, and because it can be a breaking/incompatible change for some codebases.

You can read about what the "stable" designation means here: nextjs.org/blog/turbopa...

We will make it default with a future major release number.

We end up testing Turbopack on ARM Windows because the team has MacBooks, and it's the easiest version of Windows for us to test against 🫠
