Introducing Preact Signals: a reactive state primitive that is fast by default. ✅ feels like using plain values 🥳 automatic updates when values change ⏱ updates DOM directly (fast!) 🥹 no dependencies arrays https://t.co/p4PIxThcEW

Type performance optimization will always be under appreciated because it’s not the problem people think exists It’s very important for complex type library as it can choke language server At the certain complexity point, your library will not be usual at all if not careful

I'm pretty loyal to Claude for a lot of stuff but this is the first time it feels like it's gotten noticeably less useful in an update. It makes the Claude app's chat modality feel like "we have Claude Code at home".

Claude app with skills is unusable. So slow, hyper sensitive to client device network blips, constantly falling into painful and useless tool call loops that achieve nothing ....

Claude's RSC data seems to include some not-supposed-to-be-public info. Notable things they seem to be working on: - publish artifacts as real apps ( https://t.co/nd7Vf4T3dY) - expose local MCP Servers to the web

Every tool has a "holding it wrong" factor. Comparing the impact of "holding it wrong" can be valuable in understanding DX/perf extremities. Just needs to be framed as that, not as an apples-to-apples comparison.

to paraphrase: "This example in Framework A that specifically goes against its best practises is slower than the same thing coded in Framework B by the authors of Framework B. Framework B must be better!"

It was brought to my attention that the React folks attempted to do a comparison between their compiler and signals recently, but for some reason chose to compare to... a whole different framework? and then not follow that framework's best practises. Bizarre.

Oxlint Custom JS Plugins achieved internally. In this example, I wrote a custom JS plugin that detects debugger statements, which was then detected by this JS plugin. 🌀 I see no performance regression when running through 10k+ files. And don't forget all the core components

@boshen_c For those asking about perf and interop, I'll be giving a talk about how it works at ViteConf in Oct. You should all come!
⚡ Speaker highlight: Jim Dummet, Core Team at @OxcProject As a JS Developer, every tool seems to be rewritten in Rust. But If our tools migrate to a different language, will we lose the ability to customize them? @overlook_motel explains how Oxc is aiming to "square the circle"

Preact-iso now has it's URL pattern matching logic ported to multiple languages! You can now preload JS and CSS for your app from Python, Go, PHP or Ruby.
What if client side routers URL pattern matching logic was available in multiple languages? Non-JS servers could figure out which client route matches for a request and add preload tags to preload assets (CSS, JS, images, icons) instead of just serving the app shell.

Fresh 2 has graduated to beta releases - essentially release candidates before a stable release. Fresh can now act as a Vite plugin, opening the door to HMR, faster boot times, and Cloudflare deployments. https://t.co/VcAtYmS3i3

Did you know that @preactjs is the third most use frontend framework? (According to @ChromeUXReport by number of origins.) We spoke about what Preact is, and how it's different from React with @_rschristian, Preact core member, on @JSJabber:

gotta love that the code sample introducing GitHub Spark is a typical unruly horror of hooks mess. Using AI to generate this shit doesn't make it less shit. Use something better.
