Package Phobia just hit 1000 stars 🌟 🤩 💫 github.com/styfle/package…

View Transitions just got simpler with Next.js 16.2. <𝙻𝚒𝚗𝚔> now has a 𝚝𝚛𝚊𝚗𝚜𝚒𝚝𝚒𝚘𝚗𝚃𝚢𝚙𝚎𝚜 prop. Tag your navigation with a type, and <𝚅𝚒𝚎𝚠𝚃𝚛𝚊𝚗𝚜𝚒𝚝𝚒𝚘𝚗> picks the right animation.

@mitchellh Glad to have you on board! 🎉 I'm a big fan and now bigger fan 🪭

Excited to share that I've joined Vercel's Board of Directors. Vercel is made up of builders and tastemakers that continually ship things that deeply impact how developers work: Next.js, AI SDK, v0, etc. I can't think of a more exciting place to be. Let's fucking ship. ▲ My relationship with Vercel goes back to the earliest days. HashiCorp was an early adopter of NextJS and Vercel (~10 years ago!) and it remains my default tech stack and deployment platform to this day. Ghostty's website is all on Vercel, too! Beyond that, I've been continually impressed with the teams relentless focus on shipping meaningful software. And importantly, software that has incredible taste. Now we are in the age of agentic software development. Vercel is building agentic infrastructure that I think every app and agent will need (I certainly need it!) and I can't think of a more exciting place to be. Huge thanks to @rauchg , Jeanne, Marten, @cramforce, @tomocchino and the entire Vercel team for the warm welcome. Time to work.

Next.js 16.2 • Up to ~60% faster rendering • Up to ~400% faster 𝚗𝚎𝚡𝚝 𝚍𝚎𝚟 startup • Server Function 𝚍𝚎𝚟 logging • Redesigned error page • Better hydration errors • 𝙴𝚛𝚛𝚘𝚛.𝚌𝚊𝚞𝚜𝚎 display in error overlay nextjs.org/blog/next-16-2

You can use AbortSignal.any() to combine multiple abort signals. For example, you might want a user-defined abort signal but you don't want to allow any longer than 5 seconds. developer.mozilla.org/en-US/docs/Web…

You can run Vercel's CDN in front of any app. We use it for our Discourse community. They back our forum, then the CDN gives us DDoS protection, bot management, and microfrontend support to build custom features and pages. Here's our setup ↓ vercel.com/blog/how-we-ru…

$7.99 standard .com domains through the weekend 👀 vercel.com/domains

Vercel CDN now has a dedicated dashboard experience. • Generate rules with AI prompts • Update routing rules without redeploying • View a live map of your global traffic • Purge cache by tag instantly Start building on Vercel with just a domain.

In 2019 i suggested using a temporal polyfill instead of date-fns so it’d be easier to swap after this landed The engineering lead just shook his head

@WebAppManifest @robpalmer2 There's a PR for it but it was never merged github.com/tc39/proposal-…

@robpalmer2 Perhaps, but as of today its official Github repo still shows it at Stage 0. 😀

Surely the TC39 proposal for adding enums to JavaScript should have reached Stage 1 by now. Stage 1 means problem space accepted. Enums are used in millions of lines of TypeScript code. What gives? Why is it largely being ignored?

I'm surprised that this workflow I made in 2020 is still used. At one point I thought it would get 1000 stars but it just stalled since github actions added a native cancel feature 😄 github.com/styfle/cancel-…

That was my assumption too until I did a microbenchmark. One of the reasons may be that V8 knows the input is immutable: With toSorted(), the engine guarantees the source array won't be modified during sorting. With sort(), the spec requires handling the case where a custom comparator could mutate the array mid-sort, so V8 has to be more defensive even with the default comparator.

@styfle @MozDevNet Do you know why is it so? I assumed .sort() would be faster

JavaScript now has non-mutating array methods ✨ `toSorted()`, `toReversed()`, `toSpliced()`, and `with()` return new arrays instead of modifying the original. No more [...arr].sort() to avoid side effects. Learn more 👇 developer.mozilla.org/en-US/docs/Web…

@skullface Whats the name of the band?

my bf’s band released their second single off their new album out at the end of the month and it’s on two spotify-curated playlists 🥹🥹🥹

This 2D → 3D map animation on @vercel's new CDN dashboard is absolutely magical ✨🤤

Shipped to the latest @nextjs canary: ImageResponse got 2x faster on basic images, up to 20x faster on complex ones. Plus inline CSS variables and a handful of QoL improvements.

@vercel Only found one tiny bug, cc @styfle

The new @vercel dashboard is so frigging amazing.

Vercel Queues is now in public beta. • Create queues and publish tasks • Control how work is consumed and retried • Get built-in durability and automatic scaling Built for apps and agents, Queues is the lower-level primitive powering Vercel Workflow. vercel.com/changelog/verc…

@robpalmer2 @bygregorr @jarredsumner @TC39 It’s definitely a bot posting that which is why it doesn’t make sense

@bygregorr @jarredsumner @TC39 ES has an incremental approach to ES updates, as does every JS engine. So I don't understand what this means.

ECMAScript excitement 😉 Congrats to @jarredsumner on shipping @TC39 Stage 3 Decorators in Bun v1.3.10 🎉 "one of the most requested features since 2023" It works universally - with `bun run` & `bun build` ⚠️ ES Decorators are different from legacy TS "experimentalDecorators"

You can now write chat bot logic once, and deploy across Slack, GitHub, Teams, and Discord. We're open-sourcing a new Chat SDK, a unified TypeScript library to build for many chat platforms with a single codebase. Now available in public beta. vercel.com/changelog/chat…

Agents can now make authenticated calls from Vercel Sandboxes without risking credential exposure. Safely inject HTTP headers into outbound requests, so sensitive data like API keys remain securely outside the VM boundary. vercel.com/changelog/safe…
