📮 What Flint Does Differently Flint is an experimental linter. It intentionally revisits many of the core design decisions from other popular web linters. Please enjoy this medium dive how Flint's intentionally deviating from other linters and trying new things. ❤️‍🔥 www.flint.fyi/blog/what-fl...

✂️ Knip for Editors & Agents Couldn't be more excited and proud to introduce the brand new VS Code Extension and MCP Server. For humans and coding agents alike, Knip will help keep your codebases tidy. → Read the blog post:

JSHeroes is one of my *favorite* conferences of all time. Lovely people, high quality event, and the best desserts 🍩. I tried to resist the urge to submit but couldn't. Happy new year!

Today on the pod, we wrap up 2025 with Microsoft's JS/TS modernization agent, Next.js 16.1, Bun 1.3.5, and Standard Schema V1. Plus community tips on types vs interfaces! At the end, we read some of your listener feedback and reflect on our 50+ episodes 🎉 youtu.be/q9PYRBqLNgM?... #typescript

Introducing Flint: a fast, friendly linter. Flint is an experimental linter made to validate several hypotheses: hybrid linting, streamlined rich configuration, thorough docs & plugins, and tooling coordination. Expect to hear more about Flint over the next month. ❤️‍🔥 www.flint.fyi/blog/introdu...

I wish JavaScript had an interrobang-ish operator. Like ??, but inverse: only produce the right-hand side if the left-hand wasn't nullish. Before: a ? b : undefined After: a ?! b It looks silly at first but I often write ternaries over nullish values in code and feel like this'd help... just me?

This was a lovely conversation, thanks Rafael!

HUGE thanks to the AWS Open Source & AWS JS SDK teams for an INCREDIBLE $5,000 GitHub Sponsors end-of-year sponsorship! 🤯 This is the single biggest sponsorship intake I've ever received. It's about as much as I usually make on GitHub Sponsors in ~10 months. I am absolutely floored. 1/🧵

Ah, yes, the yearly "wrapped" feature slog where I get to see memories of my dead family members. Thank you, Google and Microsoft, for reminding me of these cherished (traumatic) memories. 🖕

we released the new @e18e.dev ESLint plugin today! 🎉 this comes with 3 categories of rules: modernisation, performance, replacements it also works with oxlint and most of the rules have auto-fixes 🛠️ try it out and let us know any feedback/rule suggestions in discord/bsky/github!

I'm back home from a lovely trip to Tel Aviv for NodeTLV 2025. Thanks so much to the conference organizers for having me on as a keynote speaker - it was a fantastic conference with a ton of bright people & companies to talk to!

One of my favorite conference talk props is putting “flexible slides” towards the end. If you’re short for time, you can cover them briefly and move on. If you have extra time, you can go deeper. Demos in particular are great for this! 🧠

What a week for tooling!

ESLint Plugin Perfectionist is an excellent plugin and @azat.io is a real MVP for all the work leading it! 🎉 Congrats Azat on the 5.0.0!

It's 3am local time, I'm giving a keynote at 9:20am tomorrow morning, and I can't sleep I'm so excited. yay.

I'm at React Next today and NodeTLV tomorrow. If you want to talk about the web, open source, or just chat, come find me! 🙌

bless you. you can tuna piano but you can't piano a tuna.

Someone sent an AI slop PR to @typescript-eslint.io with a description of almost 1,000 words and no backing issue. We told them to file a backing issue, to be more pithy, and avoid AI slop. They then filed an issue with _over_ 1,000 words, clearly written with AI slop. Absolutely ridiculous.

Made a site comparing the sizes of living things :) The great Julius Csotonyi spent 5 months painting over 60 illustrations for the site, no ai used > neal.fun/size-of-life/

Do you think it's confusing how linters and TypeScript both get the same red squiggly color by default in VS Code? But you don't want to downgrade lint reports all the way to orange? Please upvote my VS Code feature request to add a "danger" style between orange and red! github.com/microsoft/vs...

I feel the dilemma is, that I feel responsible for being friendly and welcoming to make the experience nicer for newcomers to OSS, who may not yet know the manner well. But with AI messing this up, it's really hard to tell if it's a human behind I should take care or just AI doing terrible work.

"By developers, for developers" please no? developers are awful, give me any other group of professionals please

I am four repositories deep into a "bump dependencies to latest" push and I don't remember the original reason why I started it.

We've got some updates on TypeScript 7! The new native port - can type-check any project - supports --build and --incremental - has rich editor features implemented - is still 10x faster and is ready for you to try today! devblogs.microsoft.com/typescript/p...

A status update on the TypeScript rewrite TL;DR - if you haven't tried it already, you should!

I always feel bad for people who spend a ton of time on a pull request that the project doesn’t want. You can avoid wasting a lot of time by first opening an issue describing what you’re thinking of doing to get feedback before you start coding.

Dimitri Mitropoulos recently ported Doom to TypeScript, a monumental, year-long effort. He joins @joshuakgoldberg.com to talk all about the project. softwareengineeringdaily.com/2025/11/25/r...

yeah, frankly i’m fine with vibecoding and the occasional fumble from the AI. I’m not ok with “here’s my untested code, figure it out” - ai or not

I'm streaming today! www.twitch.tv/giacomo_cava...

Why don't purist functional languages allow traditional for loops? Are their developers not smart enough to understand them?

@devtools.fm is a great time as a guest, would highly recommend!

Call for guests: Looking for people to interview for @devtools.fm Requirements: - we haven’t talked (or it’s been a long time) - you build a tool for devs

There are only 7 Blind Bird tickets left! 😱 Get yours before ticket prices go up $100 💸 cascadiajs.com/2026/tickets

Reproductions should be in as few files as possible. So much easier for the maintainer to grok the issue without having to jump between a bunch of different files.

At JsConf.jp @marcoippolito.dev is telling us about built-in TypeScript support in Node. Node's type-stripping is performed by SWC and was inspired by ts-blank-space bloomberg.github.io/ts-blank-spa...

Today I gave a talk at JSConf JP covering the implementation story of recent Node.js module loader changes (compile cache, require(esm) and synchronous loader customization hooks). Very lovely conference! Slides: github.com/joyeecheung/...

🤔 What if there were a conference without talks? Just hanging out with OSS maintainers & builders, seeing what they’re working on, and learning cool stuff by actually talking to people. 🤯 What if hallway track turned into the whole event! 💡 @tannerlinsley.com is exploring it. Interested? ⬇️

Aye or Nay? `<input type=emoji>` to trigger the native emoji-picker, allowing you to pick a single emoji.

Some people seem to think if some behavior is behind a flag, the team owning the product isn't responsible for making that behavior work well, be documented, play well with other flags, etc They never think this about actual existing flags, just the flags that they want added, of course

Thank you @camchenry.com for the long development of configuring type-aware rules! tsgolint alpha soon! github.com/oxc-project/...

Type stripping is now stable. Enjoy 🌞

tinyglobby is a great success, and has shown us how much we can improve perf for everyone. here's some of the story! big thanks to @superchupu.dev and @benmccann.com for putting so much work into this and the migrations/adoption. we're lucky to have both in the @e18e.dev community 💙
