Yesterday at TPAC I publicized my draft proposal for adding a declarative templating API to the DOM. github.com/justinfagnan... The repo has: 📖 Explainers for the templating API and DOM scheduler API 🏗️ Full prototype implementations ⚗️ a JSX transform ⚛️ a mini React-like framework

In order to move beyond our industry's recurring dependence on libraries built for yesterday's browsers, we need more standards-based alternatives to the many visually-compelling resources like reactbits.dev. The influence these resources have on decison-making design engineers right now is massive.

Watch @atila.io demonstrate SolidStart's features like "single-flight mutations" and unveils the SolidStart 2.0 roadmap, which involves a deeper integration with Vite's native APIs and a shift towards a more modular, primitive-based architecture Full video: youtu.be/L0w0bnwzjGg

Frontenders, I am *begging* you to earn whatever pride you take in your work. How? By testing what you make on the devices and networks most people have. It's not hard, doesn't take long, and there are great automations like webpagetest.org that can make it even simpler.

Lit is joining @openjsf.org! 🎉 Today at JSConf, The OpenJS Foundation announced Lit is officially joining as an Impact Project! We're beyond excited for this move and look forward to continuing our work to build the open web with OpenJS! Read more on our blog: lit.dev/blog/2025-10...

I'm going to have to write a blog post on this trampoline pattern. It's very fast, as I found out, but also it lets you have code that runs sync or async depending on the data and consumer, like generators do. The DX isn't as nice as generators, but for a small perf-critical core, it's not bad.

I wrote a post about testable, production-ready middleware for @astro.build . The same concepts can be used in most backend frameworks in JS/TS, Golang, Java, etc. The main idea is the port/adapter pattern. www.lorenstew.art/blog/product...

@mk.gg I am very interested in helping get Lit integration back in Astro. I've seen this page docs.astro.build/en/guides/in... and the link to the code here github.com/withastro/as... Might you or another maintainer be able to help me get started?

Hard to call this engineering, let alone overengineering, because engineering is the practice of designing solutions to problems for users under known constraints. GoFundMe, instead, pretended those constraints didn't exist, and produced bullshit as a result: infrequently.org/2024/11/if-not-r…

SvelteKit 3 will drop 17% of dependencies thanks to new APIs now available directly in Node. We could drop another 17% if Node were to add support for cookie parsing and serialization.

🥳 CSS functions have arrived*!!! 🥳 And they are *AWESOME* Now, you can do: @​function --alpha(--color, --opacity) { result: rgb(from var(--color) r g b / var(--opacity)); } div { background: --alpha(red, 80%); } Lean more: una.im/5-css-functi... (*arrived = in the latest stable Chrome)

This post is the culmination of my thinking about (and building) SPA-like apps w minimal JS for the last 2 yrs The ideas are informed in large part by the @infrequently.org blog posts and talks Thanks @htmx.bsky.social and @astro.build for building great tools. www.lorenstew.art/blog/progres...

we just released SvelteKit remote functions. feel like 'minor change' undersells it a little tbh ✅ await in components svelte.dev/docs/svelte/... ✅ remote functions svelte.dev/docs/kit/rem... 🔜 async SSR truly can't wait to ship the rest of this stuff

This essential post by @tammyeverts.com chimes with my experiences; teams I talk with don't understand that there are huge gains to be had when they finally get perf under thresholds that they think of as "impossible" with today's JS-laden stacks: speedcurve.com/blog/web-perform…

> Peak CPU performance was probably hit in 2017. With that perspective, you start... (ahem)... "rethinking best practices". @infrequently.org's @jsnation.gitnation.org talk is pretty worthwhile and digs into the CPU limitations of the main thread. gitnation.com/contents/pro...

The video for that talk is here: gitnation.com/contents/project… And a corresponding blog post about the clashing cultures I saw is here: infrequently.org/2025/06/conferen…

New post inspired by @infrequently.org 's JS Nation talk. I hope y'all find it helpful. www.lorenstew.art/blog/always-...

Apologies, this should have been stated more clearly. This plan will hike your monthly payments. But the average family would see their payments hiked nearly $5,000 *PER YEAR*

Shout out to all the finance bros who didn’t give a shit about democracy, human rights, racism, homophobia, misogyny, the future of the planet or basic human decency and voted for the conman they thought was gonna be good for the economy. You guys are geniuses.

@infrequently.org I’ve been digging into your work to put together some training for devs at my job. I want to be accurate, so I’m wondering if this statement is true: “Building your UI with JS rather than HTML is trading C++/Rust performance for JS performance.”

You should not be using React[1], but if you do, *absolutely* avoid Next.js: eduardoboucas.com/posts/2025-03-25… [1]: infrequently.org/2024/11/if-not-r…

Your wiki is not an SPA. If it comes with a copy of React served to every page, throw it out and start over.

So here’s something I totally missed: Cursor’s composer view has an “agent” mode, giving it more autonomy. Instead of being limited to the files you select, it can open other files, look up docs, run terminal commands, etc. I’ve been using it for a few days, and honestly, it’s pretty great. 😮
