upm.sh has become my new npm package inspector! It’s fast, reliable, and does everything in the browser! And building it was easy just use the upm API haha!

unjs/obuild now supports minifyLibs and compressLibs options Selectively minify bundled deps or compress them inline into self-extracting ES modules, for when disk size matters. undici: 906 kB → 541 kB (min) → 146 kB (compressed /~5ms to extract on demand)

📦 upm 1.3: - Faster - Better hoisting - Consumes less resources on large repos - Minimal CLI progress bar + an onProgress API - Matches native-scores in independent @vltpkg benchmarks* (3.4ms/pkg => 2ms/pkg on average) *Benchmark results vary by hardware and scenario. upm is by far the smallest.

PSA: H3 Stable and Nitro RC are imminent. Closing the last-minute gaps. Sorry for all the delays, but every single one was worth it. Nitro is becoming a MINIMAL, FAST, UNOPINIONATED/AGNOSTIC Swiss Army knife for building any web app. Your agents are gonna LOVE it.

I remember when yarn was born. It was cool and fast and fancy. then it got more complex up to a point that users couldn't keep up. Now pnpm is the star. It is getting more complex requirements to be setup "as intended" and honestly i am worried. sigh... just random thoughts.

📦 jup 0.5.6 Now respects the pnpm version set in pnpm-lock.yaml with devEngines ranges like pnpm@^12 Also fixes IPC channels for Bun and Deno. Getting closer to mass adoption 🤞

There’s a Persian saying: "The potter drinks water from a broken jug." I use changelogen for literally all releases i make, yet it has had bugs over a year, but I’ve never found the time to properly fix them. Spending part of this evening on it!

I tried SIEVE a long time ago, handwritten in rou3. It wasn't that impressive, but now, for H3's route rules engine, it is effective!

New @unjs.io drop 🍕 jup: It provides shims for package managers and runtimes and automatically selects the right one from package.json. It is a full Corepack rewrite, but smaller, faster, and nicer. It supports ^ ranges, pnpm 12, Bun, Deno, Node.js, Aube, Nub. Give it a try!

🎊 srvx has reached v1.0 🎊 Two years ago, I went on an ambitious quest. My dream was to make export default { fetch } a universal consistent format for servers. srvx has been adopted and battle-tested by Nitro, H3, Elysia, TanStack, and many others projects 🖤

🏎️ perf tip of the day: If your ESM package uses "type": "module" and ships .js files, Node.js must find, read, and parse package.json to determine their format. Shipping .mjs avoids all this runtime cost. That’s why UnJS toolchain (obuild) has always shipped .mjs.

Best vacation ever! I’ve been building lots of things lately, and I should start releasing them soon... The final steps always take A LOT longer than the building itself. Releasing at least one cool project today 😁

Horrible finding: npm downloads ALL OPTIONAL PEER DEPS of packages just to resolve their metadata, then throws all away 🗑️ Fortunately, pnpm and friends don’t do this. But since many users rely on npm, we need to find work around in UnJS/Nitro packages...

Experimenting with a new library audit workflow. A script bundles the core logic (treeshaken) into a temporary directory, then spawns multiple agents to audit it. This removes a lot of bias from comments, docs, etc. Already really helped in H3.

Recently I’ve noticed Claude using strange keywords like “seam” and “chrome.” It’s getting worse. It writes great code and understands its own language well, but they’re becoming barely human-readable. I hope it’s just a glitch, but it looks suspiciously like vendor lock-in.

Side quest of the day: 🧹mermaid-compact Mermaid is great for diagrams… until noticed this cute thing, pulls in 100+ dependencies (140 MB install), and Vite emits 100+ chunks from the mermaid.esm.min import 😅 No more! The whole thing now bundles into a single ~2.7 MB chunk.
