⚠️ Security releases are now available for the 25.x, 24.x, 22.x, 20.x Node.js release lines. Please see the blog post for additional details: https://nodejs.org/en/blog/vulnerability/march-2026-security-releases

It’s here. github.com/vitejs/vite/...

JavaScript quiz: what is the output of this code? (code in the alt text for copy&pasting)

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

It seems we can now customize the select element, right? right?! Demo: codepen.io/t_afif/pen/P... via @codepen.io

It's sad that on I get to download 72k of .jpg instead of the 11k of .avif that Jake uploaded. Their was so much effort in greeting better image format, but as soon as you leave your own code you can't use them. Today I created a business profile on Google maps, .wepb was not allowed 😞

Given `const obj = { set a(v: string) {} };` What is the inferred type for obj?

I can't believe that using GPT 5.2 directly on GH to ask question about a specific repo is so badly implemented, the AI answer with completely hallucinated code that doesn't match anything from the codebase

ESLint v10 ships with a Node.js version requirement that necessitates `require(esm)`, yet the package remains CJS only. Why?

It's been more than 3 years since I started using bun as package manager. It feels like what I wanted yarn 1 to evolve in: KISS but make it fast. Sadly I've not been able to use it for my work project because not having dedupe is a nightmare in the long run. github.com/oven-sh/bun/...

Working on a page that you can search vite plugins. I'm planning to allow plugins to add metadata for that page via a field in package.json. I wonder if it's a good idea to use a generic name like `compatiblePackages`. registry.vite.dev/guide/extend...

Did you know it's better to use .map((it): Type => ({})) than [].map<Type>((it) => ({})) ? It's because of excess property checking. (TS Playground: www.typescriptlang.org/play/#code/C...) And the Prettier formatting for this will be more consistant in next release 🎉 github.com/prettier/pre...

It's probably two different groups, but I find it funny that in my feed I see both people saying AI can implement complex things and people saying we need to fund Tailwind, when in fact the usage people do of Tailwind is not that difficult to implement.

@rel1cx.bsky.social is the first person I know who is building rules for tsl and he makes me realize I don't use enough the power of rules as functions: core rules don't even have JS doc on them 🙈

After doing #20, I was wondering: What is the benefit of using Symbol.for for map keys over pure strings? And my I tried the latest version of 4 LLMs and they are so wrong. Can a human provide me with an answer that make sense?

It makes me nuts how bad TanStack router is for React HMR. Try it youself on their Stackblitz example: stackblitz.com/edit/tanstac... 🧵

Does Dan Abramov have unusual constraint, is creating his own framework or is just learning React? I'm happy the wording did change a bit, but I'm still surprised building a small SPA is still considered an edge case for the React team. github.com/gaearon/rsce... react.dev/blog/2025/02...

@andarist.bsky.social do you know why issue TS #9998 doesn't behave the same for callbacks and async/await? Is this something that could be changed behind a flag or it's considered impossible? www.typescriptlang.org/play/?ts=5.9...

Got it fixed via a custom tsl rule 🎉 github.com/ArnaudBarre/...

Vite 7.2 is out! ⚡️ 🗃️ `build.license` option 🔌 proxy + HTTP2 support 💜 and more features and fixes Don't forget to check the complete changelog at github.com/vitejs/vite/...

It took me less than 5 minutes to be annoyed at JSON configs 😮‍💨

I re-gave the React compiler a try Rolldown build time went from 1.5s to 17s 😭 Main bundle went from 1M to 1.3M 😱 I'm diffing the bundle and one reason seems to be that the compiler rewrite calls to my classNames util 🤦‍♂️ playground.react.dev#N4Igzg9grgTg...

We raised a $12.5M Series A round, led by Accel. In this next stage, VoidZero is accelerating development on both our open-source projects and Vite+, the unified JavaScript toolchain. This is only the beginning! → voidzero.dev/posts/announ...

I am looking for a full-time job. Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me. If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

Cursor 2.0: still no suggestions when renaming a variable or a file. And when asking the agent, it does it with grep and not the LSP. Do vibe coders really use an agent to rename things or they just don't care and keep bad names?

Wow just got a production bug because <> doesn't typecheck correctly when using `react-jsx`, so TS didn't catch a property changed from a string to an object github.com/microsoft/Ty...

Mac OS process isolation is bad apparently. The Notion app doesn't have any special permissions but was allowed to detect I opened a google meet link

I love esbuild.github.io/analyze/ so much that I made a hacky plugin to convert a rolldown bundle to a partial but valid esbuild metafile gist.github.com/ArnaudBarre/...

The React team once again lacking communication with the community. I'm suggesting some help to avoid bloat in the dependencies of the ESLint plugin v6, starting with a dead simple PR, no answer in 3 weeks... github.com/facebook/rea...

One less flag to enable in TS 6.0 🥳 Thanks @searyanc.dev github.com/microsoft/Ty...

It's sad that ESLint decided to not support TS config files with native node support because it would be a breaking change in case you use enums in your config 🤦‍♂️ github.com/eslint/eslin...

Is that uncommon to use @sentry/node without telemetry? `import { init } of "@sentry/node"` gives you 1.6mb when bundled with esbuild, but after some patching, I went done to <200kb

Not a fan of @bun.sh "adding" flags to tsconfig bun.sh/blog/bun-v1....

ESLint concurrency on my work codebase: ~1k files, ~160 rules, TS parser, no type-aware rules (done via tsl), no import rules I'm surprised to not get better than 1.71x and sad to see this won't improve the CI timing on GH M1 10 cores / GH runner

Funny to look back on the blog posts from AI CEO’s (This is from 6 months ago) www.businessinsider.com/anthropic-ce...

Because tsl is just a tsc extension, supporting a new TS version is trivial 🚀 github.com/ArnaudBarre/...

ECMAScript excitement 😉 Congrats to Dan Minor @mozilla.org on advancing the Upsert proposal to Stage 3 at TC39 this week 🎉 let map = new Map(); map.getOrInsert(key, defaultVal); It lets you set a default value on a map key without overwriting an existing value 👍

Let's go @daishikato.com 😂

📚 Whenever I see useCallback, I wonder: why do we need it here? And a lot of the times, when I look deeper, I see that it actually doesn’t do anything. I think a lot of code-bases would be better of just not memoizing at all - and then let the compiler do it for you:

We finally found a way to unpublish a package with 3 downloads/week

🚨 npm phishing alert! Attackers are sending emails from spoofed [email protected] addresses linking to a typosquatted clone site (npnjs.com) to steal credentials. This attack is designed to hijack npm accounts. Careful with those email links: socket.dev/blog/npm-phi... #nodejs #JavaScript

Happy to have @voidzero.dev round up my sponsorship from $250 to $256 per month ✨

Landed support for proxies in Node.js http/https builtins github.com/nodejs/node/... To enable proxies configured from *_PROXY env vars: use NODE_USE_ENV_PROXY=1. This was already implemented for fetch and released in 24 github.com/nodejs/node/... - soon the old builtins will also support it.

I made a quiz about the JS Date parser is. It's very easy and you will score very high. jsdate.wtf

Of all current TS linters, this one comes closest to the "rules as functions" design philosophy This means you can define, document, export, import, hover, jump to definition, and deprecate custom rules (and their options) just like ordinary JavaScript functions with types and JSDoc

Introducing tsl, an extension of tsc for type-aware linting! Want to speed up your ESLint time without losing the great type-aware rules from @typescript-eslint.io? Run `bunx tsl --migrate` to try it out! github.com/ArnaudBarre/...

Node excitement 😉 Node v24.3 has improved support for type-stripping 🎉 🔷 Removes noisy warning 🔷 Better compatibility The feature is almost ready to be called done. The next (and final) maturity step is to designate it as officially "stable". nodejs.org/en/blog/rele...

After running "oxc-parser" against almost 200k files I had on my laptop and reporting tens of issues that have been closed one after the other, you can now use OXC to speedup Prettier 🚀 Thanks @boshen.github.io & many others, it was a fun project!
