I'm biased, but Stricli really is a great choice if you're in the market for a TypeScript-y CLI framework.

#stricli 1.3.0 is out now, featuring "integrations" bloomberg.github.io/stricli/blog...

This is an excellent (unofficial) explainer of the long-term value of Turbopack. It takes a lot of vision and commitment to advance generic OSS infrastructure like this.

process.getBuiltinModule() is SO underrated! Before this API, conditionally using Node.js built-ins in universal libraries was dodgy.

If you're looking for Igalians on BlueSky, there is a starter pack... go.bsky.app/LDZPFo4

Anyone using --use-largepages in real-world deployments? Just opened an issue about possibly deprecating it (if nobody is using it) to reduce the maintenance churn github.com/nodejs/node/...

I've spent a lot of time in the last 5 years building tools for writers. Anyone remember Verb, or Foam? Here's the latest -- and by far the best -- iteration: Marker!

This is a really big deal. For us at Vanta, the speedup was a bit less than the highest values some teams have seen (3–5×), but let me tell you: 3–5× is still a very big deal for our CI times, and the improvement to editor performance is night and day.

the "claude ported bun to #rustlang" post is finally up bun.com/blog/bun-in-...

TypeScript 7.0 is officially out, and it's much faster! Up to 16x faster with increased type-checking parallelization

Really excited that this is out the door! Super proud of the work the team has done in the past year to get this complete. Excited for the future; API stuff is in full swing, more perf improvements, and more. Please give it a try!!!

TypeScript 7.0 is out 🎉 It's the 10x faster Go-based port 🔥 🔷 `tsc6` is for side-by-side API access 🔷 --checkers sets checker thread count 🔷 --singleThreaded keeps parsing/emit/checking together 🔷 TS 6.0 deprecations are hard errors 🔷 API access is planned for TS 7.1

Nub's package manager is now 5.5x faster than Bun on our warm install benchmark!

Landed a few improvements to the error reporting for require(esm) with top-level await (behind --experimental-print-required-tla for now): - No longer need to run the code to collect the TLA locations, so it can be enabled by default soon - Added require stack and location metadata to the error

OMG, @jddalton.bsky.social has a wild proposal for Rspack's native binding: - size: 38.4 MiB -> 13.8 MiB (-64%) - first load: 853ms -> 615ms (-28%)

Excited to share Nav262, our experimental IDE for navigating ECMA-262 algorithms, implemented by @albertotontoni.bsky.social at the University of Bergen. Repo: github.com/bldl/nav262

I've been experimenting with having `ts-blank-space` use the (unstable) TypeScript-go JS API. At first it was ~60% slower than using the TS 6 API, but with a bit of investigation, a bug fix, and a small refactor to use different API calls it is now ~24% faster! Draft PR: github.com/bloomberg/ts...

Today a number of my Investec friends ran, walked and jogged from the City of London all the way to Twickenham and I got to see everyone! It was an absolutely beautiful and kind gesture - they are amazing ❤️

An enjoyable evening with super talented people hosted by @sylwia.bsky.social & @willow.sh Lots of insightful conversation around the future of JS package management.

Thanks a ton AG Grid and @sylwia.bsky.social for hosting us! We felt all the care. Cheers for future meetups together 🤍

TypeScript 7.0 RC is out 🎉 It's the 10x faster Go-based port 🔥 🔷 `tsc6` is for side-by-side comparison 🔷 --checkers sets checker thread count 🔷 --singleThreaded keeps parsing/emit/checking together 🔷 TS 6.0 deprecations are hard errors 🔷 API access is planned for TS 7.1

Nub is a new frontend for Node by @colinhacks.com ✨ 🦀 A Rust CLI 🧱 Bundler-style JS/TS/JSX transpilation ⚡️ Fast script execution 📦 A new package manager based on Aube 🔢 Node version management The name is similar to Bun. github.com/nubjs/nub

This week I'm in A Coruña, Galicia, attending the @webengineshackfest.org 👩‍💻 where we are discussing the future of web engines and standards. Given the potential impact on future web development, I thought it would be helpful to share some of my personal notes from the event. ✍️👇

. @danielroe.dev and @patak.cat presenting at @webengineshackfest.org abou npmx.. great stuff about community in here

👉 @danielroe.dev and @patak.cat gave a fantastic talk about the @npmx.dev project. They talked about how it started, its history, community and engineering culture around it. 👉 e18e.dev is a project aimed at unite individuals to enhancing the JS ecosystem's performance.

Time for the best conference of the year webengineshackfest.org

We'll be in London next week! Come hang out with us 🤍

Today I gave a talk JSNation about the life cycle of ESM in Node.js, how it differs in other environments and the new features that will affect these stages. Slides: github.com/joyeecheung/...

Today on the pod: VoidZero joins Cloudflare, npm 12 security defaults, Angular 22 release, plus community highlights on TS tips, numpy-ts optimization & more. share.transistor.fm/s/a5575d5c #typescript

Rspack keeps pushing forward with support for the latest language features. After `import defer`, we're now adding `import source` for Wasm, following the TC39 Source Phase Imports proposal. It lets you import a compiled Wasm module directly. Thanks to @magic_akari for the contribution!

Fast declarations for monorepos⚡️ Rslib isolated declarations make `rslib build` daily type emits much faster, while `rslint --type-check` keeps full validation where you need it, such as CI. Less waiting in builds. Same type safety gate.

Jarred Sumner experiments with multi-threaded JavaScript 🧪 Filip Pizlo's "wild thought experiment" from 2017 is brought to life 🔥 Unlike existing approaches (workers, SharedArrayBuffer) this shares the JS heap. It means threads directly access the same JS objects. github.com/oven-sh/WebK...

Safari and Bun are getting a spec-compliant module loader thanks to @heimskr.io 👏 This resolves the primary ecosystem blocker that has held back Top Level Await 🎉 And positions WebKit to adopt new features such as @tc39.es Stage 3 Import Defer 👍 bsky.app/profile/robp...

Type-stripping (used in Node's *.ts support) continues to pay dividends 👍 Masaki Hara found some type syntax that was unexpectedly not erasable: adding type assertions changed the precedence of the underlying JS code 😮 Anders on the TypeScript team universally fixed it in TS 7.0 via new errors 🎉

VoidZero, the team behind Vite, Vitest, Rolldown, Oxc, and Vite+, is joining Cloudflare. Vite stays open source, vendor-agnostic, and built for everyone. https://cfl.re/4dR0LYA

Today, VoidZero joins Cloudflare. Vite remains MIT, vendor-neutral, and stewarded by the same wider team. The same goes for Vitest, Rolldown, and Oxc. Cloudflare is also committing $1M to an OSS fund to support independent development in the Vite ecosystem.

We've been working with folks from Cloudflare for a long time, and I've seen how important Vite is to them. It's telling that their first move is a $1M fund for maintainers in the ecosystem. Together with Vite's OC funds, this is a ton of support for independent devs. Massive waves ahead.

VoidZero is joining Cloudflare. Our mission stays the same: to make JavaScript developers more productive than ever before. Vite, Vitest, Rolldown, Oxc, and Vite+ remain MIT-licensed. Evan and the VoidZero team will continue leading them.

delighted to see another framework with multi-bundler support @nuxt.com 🤝 @tanstack.com

🌲Rspack's tree shaking just got smarter 🦀 Two recent optimizations remove more unused code: 1. Inlined booleans can make branch-local dependencies inactive 2. Namespace default re-exports now preserve property-level usage More precise bundles, less dead code

ECMAScript gratitude 😉 Huge thanks to @dmitrymakhnev.bsky.social for arranging to host this week's @tc39.es meeting in Amsterdam at @jetbrains.com 🙏 Dmitry was super thoughtful about all the details and an excellent communicator throughout.
