I've been mostly working on remote servers as my "sandbox" via vscode remote ssh for a while, as local containers don't offer the build power I need. Two tricks that made it easier for me:

Taking minutes at 6am and neither my brain, nor my ear, nor my hands are working 🫠

I chatted with @duswnchl.bsky.social , based in South Korea, who works at the open-source consultancy, and worker-owned cooperative, @igalia.com. We covered her experience over the last 15 years working on WebKit and Chromium. There is no paywall; give it a read! theconsensus.dev/p/2026/05/20...

Sometimes I forget how inefficient public healthcare is in Spain that I make an appointment right before lunch time, then wait for two hours without seeing the doctor and looks like it might take another two hours. Maybe it’s better to forget about the doctor and feed my immune system instead..

Do you use Node.js on Alpine Linux? We are looking for volunteers to help us bring Alpine to "Tier 2" where it would be built and released through the normal CI process. If you can help, let us know: https://bit.ly/4v03NiW

Lately I've found myself repeating the same explanations to different people about how Node.js and V8 build/test/stay in sync with each other. To reduce the parroting, here's a blog post about the workflows, challenges I see, and some hands-on tips joyeecheung.github.io/blog/2026/05...

Walked into the kitchen to finish cooking with the marinated ingredients, found someone sent by the city council to repair the building facade standing right outside my window on a scaffold, looking at my messy counter 😅

Node.js 26.1.0 is out, with a new `node:ffi` module, `crypto.randomUUIDv7()`, and many more features and bug fixes. Full changelog and download links at nodejs.org/en/blog/rele...

Landed a set of LLDB & GDB plugins in V8 to help inspect JS states in a live process/coredump together with native states ✨ The initial implementation just supports JS stack trace annotations in bt; support for object inspection is coming up! chromium.googlesource.com/v8/v8.git/+/...

For those who build or redistribute Node.js - as the V8 implementation of temporal depends on temporal_rs, this also means starting from v26 building Node.js fully requires a Rust toolchain. See github.com/nodejs/node/...

Node.js v26.0.0 is out 💚 Temporal API enabled by default, V8 14.6, Undici 8, and key deprecations as we keep modernizing the platform. Check it out nodejs.org/en/blog/rele...

The 2026 Node.js London Collaboration Summit trip report is officially live! 🚀 We gathered 50+ contributors to discuss the biggest technical shifts coming to the runtime. Big thanks to Bloomberg for hosting! 🇬🇧 Check out the full recap and recordings here: https://bit.ly/3OHPLmz

Every time my Internet seems off

I'm happy to announce Thales, a TypeScript compiler and JS engine in Lean. Thales compiles a subset of TypeScript to Lean via a shallow embedding. Thales is a bridge for TS programmers into Lean's program verification toolset. Check out github.com/jessealama/t... to get started.

Node excitement 😉 Congrats to @targos.dev on landing the V8 14.6 upgrade in upstream Node, heading for Node v26 which will be released very soon 🎉 This is the first version of V8 in Node to support unflagged Temporal 👍 github.com/nodejs/node/...

Had a blast in London! Thanks @tchetwin.bsky.social, @legendecas.bsky.social and many volunteering Bloombergers for organising a great Node.js collab summit 😇 This was one of the most attended summits I’ve been to, so didn’t get to say hi to everyone, but very happy to see many new faces!

🤌

RFC: I have a new proposal to add new vm Module primitives and a SourceTextModuleLoader API to bring the `--experimental-vm-modules` out of experiments! github.com/nodejs/node/...

TFW you have a meet up next week and you even have a session to facilitate but your tonsils are acting up and your voice is now broken 😅

Just landed in London and planning to go to the GitHub social club in London this afternoon. Wondering if anyone here is joining too, happy to go say hi there!

30 minutes into sleep and I got woken up by iPhone’s bed time alert and I couldn’t fall asleep again. This must have been the most stupid feature ever…

Spring has arrived in Galicia!

A few days in and I think my brain is gradually getting used to it. It’s amazing how a color scheme (or the familiarity of a particular one) can affect your speed of comprehension of the code but it’s useful to force yourself not to get locked into a specific set of schemes…

Finally landed this PR that has been delayed for all sorts of reasons.. Hopefully this will help get rid of the "VSCode remote SSH getting stuck connecting to my server" problem caused by the WebAssembly memory allocation issue for most people when it flows into LTS! github.com/nodejs/node/...

Just updated vscode and now I am not sure if I should just get used to the new default color scheme or set it back to the old one...

This must've been one of the most challenging things I've worked on in a while. Thanks Bloomberg for sponsoring my work on this, and everyone who helped shipping a fix in time!

Wrote a blog post about how this works: joyeecheung.github.io/blog/2026/03...

new post on my personal blog. i think these three areas often go unexplained, so hopefully this explains why some of these packages exist. these are fine to exist but the majority of developers shouldn't have to pay the cost for them.

Oh no ran into this again: thought my trackpad is broken because it was acting weird, turned out I just forgot to turn off my bluetooth mouse that was in my bag

This probably never gets old! Now it's time to think if there's a better way to make it less of a chore...

I will be speaking at #JSNation about the current lifecycle of ESM in Node.js, and the recent changes! Check out my #JSNation badge: gitnation.com/badges/jsnat.... Register via the badge and watch the stream for FREE! See you on June 11 & 15.

⚠️ Security release pre-alert: We will release new versions of 20, 22, 24, 25 release lines on or shortly after 24th March, 2026 in order to address: * 2 high severity issues * 5 medium severity issues * 2 low severity issues nodejs.org/en/blog/vuln...

This must’ve been the biggest (in size) PR I’ve ever reviewed 😬 thanks for bearing with my insistence in hooking into the module loader & intercepting in fs internals, hopefully this would make a class of monkey patching in the wild obsolete and we will have a much more robust public API for this!

I am very excited to announce our partnership @eurosky.social with @igalia.com! The partnership will accelerate the development of independent, European-operated infrastructure for the open social web, enabling developers, organizations, & communities to build new applications. cc @xanlopez.xyz

ECMAScript EXTRA-SPECIAL excitement 😉 🚨🚨🚨 IT'S ABOUT TIME! 🚨🚨🚨 Congrats to @ptomato.name on advancing Temporal to Stage 4 at @tc39.es today 🎉 Temporal is the replacement for the JavaScript Date API 👍

Node.js is moving to one major release per year starting with Node 27! 🚀 ✅ Simpler: Every release becomes LTS. ✅ Predictable: Version numbers now align with the year. ✅ New: A 6-month Alpha channel for early testing. https://bit.ly/4rnosLg

This will work with "useCodeCache": true in the next semver-minor release github.com/nodejs/node/...

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/...

Failed catastrophically at the “don’t look at GitHub” weekend challenge. But on the bright side…

Started iteration on ESM support in the Node.js embedder API with new overloads that likely will be less prone to ABI breakages as more features are added.. github.com/nodejs/node/... Initial support has released in 25.6.0 nodejs.org/en/blog/rele...

This was fun to hack on - a gdb unwinder for V8 JIT-compiled frames on x64. chromium-review.googlesource.com/c/v8/v8/+/75... Also interesting to learn this trick from the gdb source: caller's rsp before call = callee's rbp + 16, and this seems to be a conventional CFA in debuggers

I think I figured out what's going on. Here is another blog post about tinkering with Node.js Core on ARM64 Windows (and tips about reducing the wait time on Windows) joyeecheung.github.io/blog/2026/01...

New blog post on the journey of the new --build-sea flag and how SEA injection works joyeecheung.github.io/blog/2026/01...

This just landed! Thanks @addaleax.bsky.social and @legendecas.bsky.social for the reviews! It will be out in the next semver-minor release of 25, and likely backportable to older LTS - the new workflow is a compatible improvement to the existing postject-based SEA building workflows from v18.x.

Good read. A submission to the European Commission's call for evidence on Towards European Open Digital Ecosystems (importance of OSS for EU tech sovereignty, security and competitiveness). It ends with: > If you work in OSS, consider adding your voice. The feedback period ends February 3, 2026.

Now is the time to realize I have been compiling with host arch = x64 the whole time because for whatever reason I have been using x64 python the whole time to run the configure script 😅

This release contains a bunch of PRs I recently submitted to mark features I contributed to as stable/release candidate. Here is a thread about them 🧵:

This is a mitigation, not a guarantee. Stack space exhaustion recovery is NOT specified by ECMAScript. V8 does it on a best-effort basis. If the recursion depth can be controlled by attackers, explicitly limit the depth. This is what the React and Next.js teams fixed in vercel.com/kb/bulletin/....

We appreciate your patience and understanding as we work to deliver a secure and reliable release. Updates are now available for the 25.x, 24.x, 22.x, 20.x Node.js release lines to address: - 3 high severity issues - 4 medium severity issues - 1 low severity issue nodejs.org/en/blog/vuln...
