🚀 tsdown 0.21.4 just dropped. CSS Modules are now supported.
Also, the `tsdown-migrate` skill lets your agent auto-migrate from tsup to tsdown.
❯ npx skills add rolldown/tsdown --skill tsdown-migrate

tsdown v0.21 is going to be a big one 🚀
What's new:
✦ Full CSS pipeline (Sass/Less/Stylus + Lightning CSS)
✦ Cross-platform executable builds via @tsdown/exe
✦ Dep options moved to deps namespace
✦ Node.js < 22.18.0 deprecated
Try the beta: npm add tsdown@beta -D
github.com/rolldown/tsd...
I've always wanted to rewrite the `semver` package on npm — until I found that the Deno team already rewrote it in TypeScript on JSR.
So I ported it to npm instead. No more excuses not to use Deno's std library in the npm ecosystem.

👀 Turborepo is using tsdown!

🚀 tsdown v0.21 is released now!
github.com/rolldown/tsd...
🚀 Coming in the next version of tsdown: built-in Node.js SEA (Single Executable Applications) support!
Now you can bundle your JS apps into a standalone executable with a single command:
tsdown --exe
🎉 cac v7 just dropped — after 3.5 years!
✦ CJS build gone. Now pure ESM!
✦ No more Node.js APIs — runs in any JS runtime, even browsers
✦ Deno? It's on JSR now
✦ Repo refreshed with Vitest / tsdown / npmx
Thanks @egoist.dev for passing the torch 🙌

Followed up with a separate RFC at e18e to discuss the `inlinedDependencies` field as a broader ecosystem standard — naming, shape, and adoption — since it's relevant beyond npmx itself.
If you're interested in the standard side of things, come join the discussion there: github.com/e18e/ecosyst...
Wrote a RFC for @npmx.dev
The idea: surface packages that are silently bundled inside other packages' tarballs — and show their "implied downloads".
Would love feedback 👇

Also applied to @e18e.dev
Summary
Migrates all TypeScript package bundling from tsup to tsdown. tsdown is built on Rolldown and provides faster builds while maintaining compatibility with tsup's configuration patterns.

Landed initial support for ESM in Node.js SEA: github.com/nodejs/node/...
Similar to CJS entrypoints, it only supports importing builtins, so generally require bundling. @nodeland.dev is working on support for VFS in SEA that will unlock loading other modules within SEA github.com/nodejs/node/...

This uses the new StartExecutionCallbackWithModule embedder API added in #61548 to support ESM entrypoint in SEA via a new configuration field "mainFormat". The behavior currently aligns ...
