Working on something very exciting! I’ve rebuilt the whole thing from scratch three or four times already. It has now been extracted to a new RFC, and I’m aligning it with the specs all over again. Getting close to the final implementation. Wish me luck!

Today @kane.tw told me that unwasm has issues parsing some opcodes. It wasn’t the first time with this issue. Now the parser is replaced with a tiny one that extracts only what unwasm needs. A few more changes, the install size is down to 38.7kB/329kB from 417kB/2.44 MB 🚀

The latest version of VS Code (1.129) has a new experimental Modern UI (the one on the right) with rounded corners everywhere. I am enabling it in Coderaft to try! How do you like it?

New hook in H3: onDispose(event, cb). Fires when a request is truly done: response finished, client disconnected, or the stream errored. Works identically on all runtimes!

🔥 SRVX IS FAST 🔥 * benchmarks are just an indicator

Did you know that even a simple console.log() per request can hugely hurt performance? The built-in logger in the next h3/srvx release batches writes and caches the timestamp (Intl), cutting logging overhead ~60–85%.

Did you know that H3 has a built-in `writeEarlyHints` utility that sends early hints? (Thanks to the initial contribution from @danielroe.dev, we’ve had it since the early days!)

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

🍦 unjs/unctx v3: - Zero dependencies, with optional transformer - Faster transformers (thnx @thealexlichter.com) - Uses oxc parser for transform - AsyncLocalStorage doesn't needs to be polyfilled - Fixes memory leak with resources like timers in context

Had a fun pair-programming session with @rihan.dev today. And guess what? We got to write a few lines of code by HAND!

nowadays i work on multiple projects, in multiple branch worktrees, across multiple sessions all in parallel. zigpty has a built-in attention detection system that tells me when an agent is done. and i can close my laptop and pick up sessions from my phone while cooking!

Generating OG images with Nitro and Takumi. Instant and beautiful!

srvx 0.11.22: - New `trustProxy` option to respect x-forwarded-* headers in req.url (works with Node, Deno and Bun) - New `mtls` plugin to request client certificate during the handshake (thnx @sandros94.com) - Complete AWS streaming docs (thnx @oskarlebuda.bsky.social)

Nitro’s routeRules engine will be 9–110× faster in the next release (over 250x when new security guards kick-in). This is powered by a new complex pattern-overlapping analyzer in rou3, enabling route rules to be pre-merged at compile time. And that’s not all 😜

Figured it might be better to think more about designing the right `defineQueryHandler` API. As the first step, the essentials, types + .query() support and spec-compliant utils (`requireContentType` and `appendAcceptQuery`) have landed.

I noticed code-server hasn’t published a new npm version in the past three months! although their GitHub releases still include tarballs. Coderaft is now upgraded to the latest VS Code (127). It’s my primary (in-container) IDE for almost everything and I’m really happy with it!

Working on first-class QUERY support in H3 (RFC 10008). Feedbacks on the ergonomics are welcome!

This took around 20 hours of focused work, alongside a bunch of other projects. With Sonnet 5 for discovery, Opus for execution, Fable as the brain, and pspace as my custom dev environment, this moved insanely fast. In the old days, this probably would’ve taken more than a week of focused work.

🌟unjs/ocache 0.2 is packed with fixes for 30+ long-standing issues. Landing soon in the next Nitro v3 beta.

314M 💛

/loop until either my Fable usage runs out or it’s 4:20 AM

In crossws 0.4.9: - App-level ping/pong hooks - Manual subprotocol negotiation - ws() plugin now works out of the box in srvx and h3 + caches resolution for speed - Universal idleTimeout (30s default) to help prevent memory leaks

webpack-dev-server, http-proxy-middleware and @rspack.dev are now using modernized unjs/httpxy 😃🔥

🌳 In h3/rou3 v0.9.0: 🔧 routeToRegExp() is now PCRE2-compatible 🔁 new regExpToRoute() to map proxy regexes back to rou3 patterns (URLPattern-ish) ✨ routesOverlap() / findOverlappingRoutes() built to handle complex logic like overlapping route rules in Nitro

What a fabulous day! Only my brain is officially fried from all the context switching 😵‍💫

Latest h3/srvx release is out with 3 fixes, (thanks to Fable 5), plus a new universal maxRequestBodySize option. This helps harden server security against clients sending large request bodies, especially when running without a CDN.

In crossws 0.4.8: - Proxy works out of the box with Unix socket targets. - WebSocket client is fully consistent across node/ws, Bun, and Deno. Set headers or use ws+socket:// targets without worrying about runtime inconsistencies. crossws.h3.dev/guide/client

/burning Fable tokens (CC Max) for some critical h3 tasks 🔥

It started while I was trying to improve my security hygiene. Now everything I do runs in disposable background containers with regular updates, keychain integration, and security audits. No more Homebrew, yay, or even VS Code on my systems!

My dev environment is now custom-built with Nitro, CrossWS, Zigpty, Coderaft, and other in-house goodies from the UnJS, Nitro, H3, and PiThings. It’s so lovely to build with the same tools I’m improving every day. Can’t wait to share more!

In h3/crossws 0.4.7: - Backpressure control API - Proxy with async targets - Several fixes for Deno compat - Sync backplane: pubsub / chat rooms over Redis, Postgres, BroadcastChannel, or Node cluster workers (will be availble soon in Nitro v3!)

Latest unjs/nypm now supports Nub by @colinhacks.com 🎉 It also respects devEngines.packageManager alongside the existing packageManager field in package.json. github.com/unjs/nypm/re...

unjs/exsolve v1.1.0 is out 🚀 - More stable cache store ~10% faster with default conditions, thanks to @thealexlichter.com - Synced ESM resolver with latest Node.js upstream now #/ subpath imports work! github.com/unjs/exsolve...

500 ok 👍 by @ns.nl

The latest version of unjs/nypm now auto-detects Aube (by @jdx.dev). 🌈 nypm can be used for automated tasks while respecting the user's package manager. npm, pnpm, Yarn, Bun, Deno, and Aube are now all supported through a unified/compact API. - github.com/unjs/nypm - aube.jdx.dev

Nitro v3 260610 has a couple of nice improvements to Vite and prerendering support. It’s getting closer to RC (and Nuxt v5!). github.com/nitrojs/nitr...

ocache now supports .expire() on cached functions and handlers 🕰️ (available in Nitro v3!) Unlike .invalidate(), it marks the entry stale without evicting it. The cached value keeps being served while a fresh one is fetched in the background. Cool idea by @atinux.com

unjs/env-runner now supports virtual modules across all supported runtimes! No bundler required. This unlocks some exciting new possibilities for Nitro.

Used to be a Vampire couple of years ago… cronotype.vercel.app/pi0

Hear me out: What if, instead of spamming GitHub with AI-generated BS, there was a platform to donate AI credits (to orgs, projects, or even a single issue)? Maintainers could use them however they see fit and credit donors back.

TIL i am watching 856! github respos and my inbox is empty. I have a bot that dismisses lots of noise but this should be lower... github.com/watching

👀 If I were a hacker, I would: 1. Sit on zero-days. They are increaing , while more people starting to delay or disable auto-updates. What could go wrong?

Back on maintenance. Had to make first user ban for spamming AI-generated PRs in UnJS. TBH, some were not bad, but digging through dozens of PRs and then burning more tokens to make them mergeable is not just worth it. 🧠 The human mind is, the only truly valuable resource.

As part of locking things down, I’ve made a 3rd GitHub account: pi0x. It’s me.

🚧 I am a little bit slower than usual at triaging issues and PRs in unjs, h3, and Nitro. Making my maintenance workflows more automated and secure. Please privately ping me if anything is real blocker.

IPFS is wildly underrated.

NODE.js 20 IS 🪦EOL. YOU SHOULD EITHER UPGRADE IT OR NOT TOUCH YOUR DEPENDENCIES AT ALL, AT THE RISK OF RUNNING VULNERABLE, BROKEN STUFF IN YOUR PRODUCTION ENVIRONMENT. INSTEAD OF PUSHING MAINTAINERS FOR LEGACY SUPPORT, PUSH YOURSELF, YOUR VENDOR, AND YOUR OPS GUY TO UPGRADE!

After my last post about my article on live coding inside slides, I kept thinking about making this experience even smoother 🧘🏼‍♂️ I built a Slidev addon to embed a real IDE directly in your presentations 🤯 Powered by CodeRaft by @pi0.io ⚙️ Give it a try and let me know! 👉🏼

Recently rented an office to work outside of home. Most of the times i am the last one leaving the building and locking the doors. Reminds me of university life. Boy i love what i do but also sometimes feel what if grown as a farmer. Perhaps more useful to humanity too.

Remix 3 is so cool. But it's not made for bundling. I wired it through @nitro.build and @vite.dev 📦 163 MB → 295 KB dist (565× smaller) 📁 2,891 → 25 files ⚡ 389ms → 59ms startup 🚀 deploys to anywhere nitro does. Zero config.
