It’ll take a bit before it’s widely usable but I look forward to cleaning up config file boilerplate. 🎉

Got inspired by @kentcdodds.com to play around with MCP UI in Angular. Definitely rough around the edges but it's really neat to see this all come together. 🌈

It's been really fun to explore how API design and system prompt can come together to make code generation a lot more reliable over the past few weeks. And now anybody can! 🎉

Today’s first: Published my first security advisory write up! If you’re running Angular SSR in production, this may apply to you: github.com/angular/angu...

Had some fun getting my @storybook.js.org to correctly simulate a streaming genkit LLM response (using msw and/or fetch-mock). For future reference: gist.github.com/jkrems/ce62b... #storybook #genkit

Presenting the BRAND-NEW season - @dimension20.bsky.social On a Bus! 🚌 DM'd by Katie Marovitch, and as players: Aabria Iyengar, Brennan Lee Mulligan, Jasmine Bhullar, and Mark Mercer!

New blog post on serializing promises in React. Learn how RSC serializes data between the server and client. twofoldframework.com/blog/you-can...

That’s so sad and just doesn’t make any sense. ☹️ Adam’s an amazing voice for the web and its users.

Dark mode toggles should be a per-site browser preference, just like zoom. Why are we still reinventing the wheel with JavaScript? Let's make dark mode a browser-native feature. bit.ly/dark-mode-is...

Our toddler discovered “Rock around the clock” tonight and I’m afraid he’s taking the lyrics a bit too literally.

Just released Node.js v23.8.0. It includes an initial implementation of URLPattern, an new flag to load system certificates, zstd, and more! nodejs.org/en/blog/rele...

TIL: it’s easier to implement web sockets from scratch* than to teach various Java clients that bidirectional streaming over HTTP is possible.

I remember @seldo.com showing download stats as “share of registry” which removed some of the general ecosystem growth noise from the stats. Is there some site that offers those numbers today? Raw download counts are super hard to interpret correctly. :(

@soldair.bsky.social I knew it’s been a while since mana burn was removed. Didn’t realize it was in 2009 (!)…

Now just give me string concat in calc and I think we can call the web “done”. 🎉

The race is on: Will I get all post-holiday access issues resolved before the first meeting of the day? I’ll know in about 5 minutes.

I'm starting to think that the hard part will be to turn this back into JS... Maybe something higher level than a generic loop node would be better after all.

TIL: Just by multiplying safe integers, you can reach NaN. Stupid floats.

Ecma just approved the 1st edition of the new "Source map format" standard, ECMA-426! 🎉 tc39.es/ecma426/2024/

A follow-up meeting was just scheduled for “next year” (January) and I’m not sure how I feel about that.

My talk from this year's We Love Speed is on YouTube! 👇 In "Tight Mode: how browsers REALLY load web pages", I take a very deep/very nerdy dive into why browsers sometimes intentionally delay loading resources, why they all do it differently, and why they should *stop clowning around* 🤡 #webperf

🚨 @analogjs.org 1.10 is out! ⚡️ Big performance improvements for @vitest.dev ✍️ Introduced Form Server Actions 🤝 Support for #Angular v19 👀 Route debugging page Release notes: github.com/analogjs/ana...

“Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.” I figured it out. @littledan.dev is in every standards group and GitHub issue because there’s an army of clones: the “little dans”. Big Dan only delegates.

A two story office/library 📚 to die for

Woah, had to do a double-take to realize this was talking about key outside of loops. Makes sense in retrospect but never considered this behavior!

📢 TypeScript 5.7 is here! Now with ✅ Better checks for uninitialized variables ✅ Smarter tsconfig lookup in editors ✅ Improved startup time ✅ Stricter checks for JSON imports ✅ Extension rewrites for relative imports and more! Try it today! devblogs.microsoft.com/typescript/a...

I just realized that my talk with @thepunderwoman.com on #Angular #SSR is finally public. We've already made great progress on some of these pieces, but if you missed it and are interested to see where we're going, take a look! www.youtube.com/watch?v=FVCk...

Finally made it to this office early enough to try out the piano before people start working.

I’m beyond excited to live in an age where people think that adding methods to the Array or Date prototype is a new idea because they don’t see it done in commonly used libraries. www.reddit.com/r/javascript...

Extension rewriting is huge. There’s some really nice dev/publish flows unlocked by this. Looking forward to some awesome publishing tools making use of this.
