Introducing tsrs: a Rust port of the TypeScript compiler 🦀 We are not forking TypeScript! ◆ In close collab with the TypeScript team ◆ Up to 8x faster than TS 7.0 & ~70% less memory ◆ Runs in WASM (works in your browser & workers) ◆ Soon part of Oxc npx tsrs blog.cloudflare.com/typescript-r...

Neat browser-native build by Jakub Chmura at Software Mansion! 🖼️🔍⚡ They ported EmbeddingGemma 2 to ruNNtime (TypeScript WebGPU engine on TypeGPU) to search a local photo gallery in natural language 100% on the browser GPU. Repo: https://github.com/software-mansion/runntime

My thoughts on the current state of AI driven software development, why I'm no longer concerned about a runaway intelligence explosion, and what I think is a far worse outcome we could be walking into maevyn.codes/decoherence

Firefox 158 landed today! For web devs: 🎉 JPEG XL support, including full progressive rendering. 🎉 'navigate' on notifications, so they can go to a URL without firing events. 🎉 WebGPU's float32-blendable 🎉 WebGL's EXT_polygon_offset_clamp And more! developer.mozilla.org/en-US/docs/M...

With MSW 3.0 released this week, I want to try something new to make the project financially sustainable. I wrote an open letter about the project, its history, and impact on the ecosystem. I ask for five minutes of your time to read it. Thank you. mswjs.io/sponsor

ECMAScript excitement 😉 Congrats to @ashley-c.bsky.social from TechAtBloomberg on advancing the Composites proposal to Stage 2 at @tc39.es today 🎉 Composites are objects that are compared by value instead of identity. They are an evolution of Record & Tuple proposal.

I'm excited to announce MSW v3.0! 🥳 - Leaner dependency graph and smaller size; - ESM-only; - Granular entrypoints; - GraphQL subscriptions; - Socket-based network interception in Node.js; - And much more! mswjs.io/blog/introd...

Vite+ 1.0 is here 🚀 A single `vp` CLI for managing your Node.js runtime, package manager, and frontend toolchain. Built on top of Vite, Vitest, Rolldown, Oxc, and tsdown. All with a single config. Free and open source under the MIT license. Start with `vp create` or migrate with `vp migrate`.

This is such a silly mistake and yet I see you making it all the time in your tests. ❌ Do NOT run cleanup after assertions ✅ Schedule the cleanup via hooks or use Disposable Objects A seemingly tiny change that'll have tremendous impact on your tests, especially memory-wise.

It's been a while... Introducing Devframe v1.0 🚀 The framework for building DevTools that can run everywhere, for any meta-framework, for both humans and agents. Check out the announcement post and join our Discord 👇

💡 OpaqueRange is nice This inspired me this universal syntax highlighter that works with a gpu model to highlight a <textarea> The fun part is that you can mix multiple languages within the same <textarea> 🤪 github.com/slorber/gpu-...

For the last 2 years I have been tracking a generational change in the nature of software development, and I think I've finally decided where all of this turmoil is going to end up. It's good news, but not for everybody. https://seldo.com/posts/we-are-all-product-engineers-now/

gpu-lexer : coloration syntaxique expérimentale via WebGPU, sans grammaire par langage. Un modèle devine le type de chaque token selon le contexte, même sur du code inédit. Bundle de 27.5KB, 90,2% d'accord avec Shiki. ⬇️ https://gpu-lexer.vercel.app/ 📬 Recevoir ma veille

I wrote about what I've been up to with my new programming language! Zena targets WebAssembly GC, with a TypeScript-like syntax, sound type system, and lots of cool features like pattern matching, async cancellation, borrow checking, WASI integration, and more! justinfagnani.com/2026/09/09/z...

Vitest 5 is here! 🎉 - Big performance improvements (vm pools up to 53% faster, ~18% boost across the board including Browser Mode) - New builtin Trace View in Browser Mode - Nested projects support - New benchmarking API - New `vi.when` API - Better defaults - And a lot of bug fixes!

For those looking for more details after the release announcement here they are. Solid's approach to Async is one of kind. And more than that it has real implications. www.solidjs.com/blog/async-s...

If you’re not stalking TypeScript PRs, you might be surprised how much you can do with the API in nightlies (and even in 7.0 stable), so here’s a tiny demo that I think hits some of the highlights. 🧵

🚨 Solid 2.0 has reached Release Candidate! 🎉🥳 Async is first-class — computations return promises, the graph suspends and resumes itself. Plus optimistic mutations and a reactive core rebuilt from scratch. The Big Reveal 👇 www.solidjs.com/blog/solid-2... 1/3

New demo: Animated CSS Grid Layout. codepen.io/bramus/pen/o... Here’s the thing: No View Transitions. No JS at all. Instead, it uses Anchor Positioning to anchor the cell contents to the cell. Then, CSS transitions are used to animate the contents to their new location as the grid re-layouts.

ECMAScript Euphoria! 🎉 We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4. Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌

🎉 I'm so excited that scoped custom element registries is landing in Chrome and Edge! 🥳 This solves one of the biggest complaints with the web components APIs: the global tag name namespace. Standards is a long game though: I first proposed this in 2017! 😲 developer.chrome.com/blog/scoped-...
