windows performance analyzer is a fantastic tool. i usually don't expect such high polish on a developer-oriented tool, but the team has certainly knocked it out of the park. cc @us.graphics :)

Slides done for one of my two upcoming tc39 agenda items. Composites comparator choice: docs.google.com/presentation... (Yet to be finalised) agenda here: github.com/tc39/agendas...

Calling all web developers! Browsers are all meeting up next week (www.w3.org/events/tpac/...). I want your voice to be heard! Tell me your biggest problems, and tell me what you want to see from the platform. What problems are tough to solve, but could be easier?

A V8 use-case gets 4000% faster 🔥

ECMAScript excitement 😉 Congrats to @manishearth.bsky.social on unflagging TC39 Stage 3 Temporal in V8 today. Heading for Chrome 144 🎉 By many metrics this new date-time API is the single biggest change to JS ever 🔥 V8 uses Boa's temporal_rs by @jason-williams.co.uk Kevin Ness & Manish 👍

My child's school's third-party online learning platform has been enhanced with AI. It offers to explain terms in detail, e.g. what are variables and constants. If you choose this, the child is first asked if they wish to pay for premium, or they can "Ask my parents" to pay.

here's what the @e18e.dev community has been upto for the last couple of months! huge thanks to everyone involved 🎉 much more to come very soon, and we have a roadmap of some super useful tools in the works

Thanks @mmocny.com for the container timing shoutout and stealing my low effort diagram 😂 Great talk @ #perfnow

Golden hiring opp.

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...

Proud to be in this list of 22 open source projects receiving grants from the CEO of Vercel. It’s great that he also brought attention to these projects. I’m especially glad to see @e18e.dev there. They’re systematically speeding up the Node.js ecosystem for years. rauchg-oss-grants.vercel.app

I'm pleased that this year's GitHub survey acknowledges that untyped & typed JavaScript deserve to be counted as part of the same ecosystem. 🔶 New repos (last 12 months): JS 9.3M, Python 9.3M, TS 5.4M 🔶 Contributor delta (last 12 months): TS +1.1M, Python +0.9M, JS +0.4M 🔶 Contributor count chart

Big news in this year's GitHub Octoverse report: TypeScript is now the most-used language on GitHub! We are thrilled and grateful to see the TypeScript and JavaScript community continue to grow and thrive. 🚀 Read up more at github.blog/news-insight...

Something rare is happening. We're opening up a position in the @storybook.js.org team! Not only that, but it's fully remote, in Central European Time! If you want to maintain OSS, love the JS ecosystem and enjoys tinkering with the details that makes it all work behind the scenes, check it out!

TC39 Stage 3 Import Defer is steadily progressing in Chrome V8 due to Caio Lima at @igalia.com together with reviewers. Parsing support was merged in upstream V8 on Thursday. chromium-review.googlesource.com/c/v8/v8/+/70...

Hot off the press! 6.8 released with some big features 🎉 ⚡@vite.dev by default 🕚 Compatible with libraries from 8+ years ago* ✨ New APIs: renderComponent, additional reactive data structures 🤝 No more hbs by default (strict: true) Read more here: blog.emberjs.com/ember-releas...

We are still looking for feedback on tsgo, but it is worth calling out we expect some type-checking changes that you may need to adapt to. The native previews are easy to grab from npm, and are published nightly to try out! www.npmjs.com/package/@typ...

📝 Importing vs fetching JSON JSON imports are now supported cross-browser, but when would you use them rather than fetch()? jakearchibald.com/2025/importi...

ECMAScript excitement 😉 Congrats to @ahabhgk.bsky.social on shipping experimental support for TC39 Stage 3 Import Defer in Rspack 🎉 Like webpack, this is opt-in and excludes supports for dynamic import.defer() github.com/web-infra-de...

Today on the pod: Node 25 V8 perf updates, Remix V3 will use Preact, TypeScript in SpacetimeDB, Map upsert proposals and 15 npm packages you can ditch for native Node features! share.transistor.fm/s/1ee81010 #typescript

Built-in HTTP proxies are now on v22 😇 (Going to update the version mentions in a WIP guide on using Node.js in enterprise network environments)

Big up to new #oxc contributor @arsh.sh, who showed up out of nowhere and is tearing through our issue list! He's just implemented support for all the comment-based APIs in Oxlint JS plugins. github.com/oxc-project/...

An implementation of TC39 Stage 3 Import Defer is being worked on in Chrome's V8 engine by Caio Lima at @igalia.com sponsored by TechAtBloomberg 🎉 This is a performance feature that enables lazy execution of JS modules ⚡️ chromium-review.googlesource.com/c/v8/v8/+/70...

An implementation of TC39 Stage 3 Import Defer is being worked on in @rspack.dev by @ahabhgk.bsky.social 🎉 This is a performance feature that enables lazy execution of JS modules ⚡ webpack already has (partial) support, so it makes sense for Rspack to achieve parity. github.com/web-infra-de...

A blog post on Vite+ and the future of web tooling 📜 🔶 A new CLI that combines Vite, Vitest, Oxlint, Oxfmt 🔶 Centralized simple config 🔶 Adds easy monorepo tooling 🔶 Free for individuals, OSS, & small companies 🔶 Existing tools remain independent & assertively MIT

This matches my experience in a Waymo. After a week of using them as a ride-sharing replacement in April 2025, my initially-terrified family did not want to use anything else. It felt like a premium service and aroma but did not cost more.

For that reason, someone at @viteconf.org jokingly said Vite is the United Nations of JavaScript ⚡️

This week's @viteconf.org was a LOT of fun. It rekindled some of the neutrality/plurality magic from the old JSConfEUs. Like Switzerland. Bridging communities & frameworks. Folk cheering each other on, celebrating collaboration 🎉 TechAtBloomberg folk showed up in force - 7 of us!

What an excellent group 🙌 Best part of meetups and conferences @viteconf.org

. @viteconf.org was the first in-person conference I've been to and it set the bar high! Excellent talks and really welcoming atmosphere. Amsterdam is a fantastic city. Thanks to everyone for the geeky JS chats.

Future of the Web panel at @viteconf.org were asked about the most exciting upcoming web standards: 🔶 AsyncContext (@ryansolid.bsky.social) github.com/tc39/proposa... 🔶 import defer (@evanyou.me) github.com/tc39/proposa... 🔶 Module Declarations (@ryansolid.bsky.social) github.com/tc39/proposa...

Igalia is honored to have been awarded a commission from the Sovereign Tech Fund to advance the @servo.org web engine. STF’s support will advance a multi-pronged effort focused on improving Servo’s accessibility, WebView API support, and project maintenance. Details: www.igalia.com/2025/10/09/I...

With declaration emit thanks to isolated declarations 😅

Just talked about Vite+ at @viteconf.org - check out more at viteplus.dev :) More detailed announcement on Monday!

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most. So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion. interop-rank.jakearchibald.com

Vite+ now has a website. Licensing for existing projects remain MIT. Whereas Vite+ will be "source-available" and free for open source, non-commercial usage. viteplus.dev
