Signals, the push-pull based algorithm — Willy Brauner
We have been using Signals in production for years via several modern front-end frameworks like Solid, Vue, and others, but few of us are able to explain how they work internally. I wanted to dig into it, especially diving deep into the push-pull based algorithm, the core mechanism behind their reactivity. The subject is fascinating. The state of the world Imagine an application as a world where w
Scroll Restoration | TanStack Router Docs
Hash/Top-of-Page Scrolling# Out of the box, TanStack Router supports both hash scrolling and top-of-page scrolling without any additional configuration. Scroll-to-top & Nested Scrollable Areas# By default, scroll-to-top mimics the behavior of the browser, which means only the window itself is scrolled to the top after successful navigation. For many apps however, it's common for the main scrollabl
ArrowJS — The first UI framework for the agentic era
The first UI framework for the agentic era A tiny, blazing-fast, zero dependency, type-safe framework with no build step required. ArrowJS ships with the ability to isolate component logic inside Web Assembly sandboxes while rendering full inline DOM directly in your app — no iframes, no pre-defined UI components. Use it to build fast, maintainable applications — or to ship safe, flexible, on-dema
GitHub - chenglou/pretext
Pure JavaScript/TypeScript library for multiline text measurement & layout. Fast, accurate & supports all the languages you didn't even know about. Allows rendering to DOM, Canvas, SVG and soon, server-side. Pretext side-steps the need for DOM measurements (e.g. getBoundingClientRect, offsetHeight), which trigger layout reflow, one of the most expensive operations in the browser. It implements its

External import maps, today! • Lea Verou
A few weeks ago, I posted Web dependencies are broken. Can we fix them?. Today’s post is a little less gloomy: Turns out that the major limitation that would allow centralized set-it-and-forget-it import map management can be lifted today, with excellent browser support! The core idea is that you can use DOM methods to inject an import map dynamically, by literally creating an <script type="import
Temporal: The 9-Year Journey to Fix Time in JavaScript
Welcome to our blog! I'm Jason Williams, a senior software engineer on Bloomberg's JavaScript Infrastructure and Terminal Experience team. Today the Bloomberg Terminal runs a lot of JavaScript. Our team provides a JavaScript environment to engineers across the company. Bloomberg may not be the first company you think of when discussing JavaScript. It certainly wasn't for me in 2018 before I worked

Release v2.0.0 Beta - The <Suspense> is Over · solidjs/solid
I know you all probably weren't expecting this announcement next. But after reviewing the roadmap, we spent so long iterating in the Experimental phase, most of the goalposts within Alpha don't appear relevant enough to warrant their own phase. Instead, I'm happy to announce today that Solid 2.0 effort enters the beta stage. There will be bugs and rough edges we need to work through with the ecosy
Oxfmt Beta
We are excited to announce that Oxfmt has reached beta. Oxfmt is a Rust-powered, Prettier-compatible code formatter built for the JavaScript ecosystem. It is designed to deliver full compatibility with modern tooling while dramatically improving performance. In benchmarks, Oxfmt is more than 30× faster than Prettier and 3× faster than Biome on an initial run without caching. See the full benchmark
Writing Good Unit Tests
In my first job as a software engineer the project I was working on grew out of control. As often happens, use cases were added without proper refactoring and with more users we were drowning in support tickets and nothing seemed to work. It was clear we needed to push for quality so we started adding unit tests. The tech lead at the time mandated high test coverage. But here's the reality: writin
