A new free BigQuery dataset of anonymized real user Core Web Vitals from 10,000 large Cloudflare-fronted sites, updated daily and covering Safari/WebKit as well as Chrome. The post covers some of the initial findings, including how downloads are usually the smallest part of a slow LCP.
Nolan, a big Web platform advocate, casts a thoughtful look at the common alternative, exploring why we often rebuild things platforms already give us in JavaScript and CSS.
The online travel company moved its biggest React SSR service from pm2’s process-based cluster approach to Platformatic’s Watt and worker threads, then tuned load balancing and V8’s GC to get noteworthy gains.
A proposed diagram notation for React apps that shows both where each element ends up (the parent tree) and which component created it (the owner tree), with marks for context, Suspense, memo, error boundaries and RSC. There's also a playground that draws trees from code you paste in.
Meta had delayed the release of Muse for months due to safety concerns. However, the success of an AI agent created by a startup called Instinct led Mark Zuckerberg to push for a launch due to fear of losing a competitive edge. The launch was successful and has given Meta an early lead with agents. The agent has only had a few safety hiccups, like when it gave out a user's address to a seller on Facebook Marketplace without permission.
The big news is Cache Components is now recommended, and enabled by default if you use create-next-app. Agentic tooling gets some upgrades, and there are smaller improvements for all apps.

Chrome 155, released yesterday, introduced support for JPEG XL (.jxl) images. They can offer 30-50% better compression than JPEG, HDR support, and more.
An open-source, clean-room reimplementation of Microsoft Word in pure Rust
Six years after the road to Preact 11 began, the latest version of the popular "alternative to React with the same modern API" is here, with improved hydration, automatic ref forwarding, and an ESM-only package. The upgrade guide covers the changes.
A more substantial minor release than usual with a new --process-timeout flag that ends a process after a set time (even mid-busy-loop), node:sqlite gets virtual table support, Buffer.stringLength(), and Alpine (x64) is promoted to tier 2 support.
Apple is set to unveil new smart home products tomorrow. The centerpiece will be a smart home hub called the HomeView that essentially serves as the Siri command center for an Apple-powered household. There will be a countertop model with a metal base and a wall-mounted version with a flat, square base that sits against the wall beneath the display. The HomeView will only support a limited selection of Apple applications, and there will be no App Store for downloading additional software.
Almost a decade after creating React Charts, Tanner returns with a rethink: charts composed from typed marks and scales, rendered with SVG or Canvas, with a React adapter. The example catalog shows off its range, along with code samples.
Devographics’ annual look at how we use HTML, forms, web components and browser APIs is back, and should take 10-15 minutes. Browser vendors use the results to prioritize their roadmaps, so your answers help decide what ships next.
An agent skill for creating detailed, interactive isometric illustrations of real-world machines and complex systems. Generates polished SVGs with optional WebGL shaders and 3D effects.
A meaty release for the full-stack Vue framework with a server layer that no longer ties you to Nitro (pure Vite server builds are now an experimental option), built-in sessions, Vue Vapor support, and a new CLI (Nuxt CLI 4.0).
In V8, objects created with { __proto__: null } or Object.create(null) start off in a slower ‘dictionary mode’. Creating a plain object and nulling the prototype afterwards keeps it fast, as Matteo shows.
Digs into the React Compiler’s output, then prototypes extra compiler passes like inlining, blocks and selector inference to see how much faster React could get.
Shenzhen opened access for nighttime deliveries by driverless vehicles in March. Night operations make otherwise idle vehicles and infrastructure productive. It also means quieter roads, reduced pedestrian traffic, and lower congestion. Driverless vehicles eliminate the cost of a human: they don't need night shift wages, they don't get tired, and they don't need to be paid extra for driving in the rain.
The new TanStack charting library is officially stable. Small bundles, fast updates, composable, type-safe. Similar to other TanStack libraries, it comes with a framework-agnostic core and a React Adapter.
✈️ Airline Sites are Slow, but They Don’t Have to Be — Some interesting analysis of the performance of over 100 different airline websites using real-user metrics. A massive ~95% fail the Core Web Vitals test on mobile.
GridCraft: an open-source, clean-room spreadsheet (Microsoft Excel-style) in pure Rust. By ArtCraft.
Claude Code has just added support for Mods, a way to extend the agentic coding harness with JavaScript so you can watch events, change behavior, and draw custom UI. Addy builds a mod here in ~80 lines that shows a live 'forecast' of your context window.
How do fetch wrappers like Ky, ofetch, and Wretch behave if you abort mid-retry? The author of ffetch tested eleven options and found five still attempt retries after cancellation.
React Aria has a new swipeable Sheet component, and Devon explains how it works. Rather than handle touch events in JavaScript, it uses an oversized scroll container with CSS scroll snapping and view timelines to get native momentum, rubber-banding, gesture-synced animations, and more.
Borrowing an idea from one research discipline to solve a problem in another is an age-old scientific trick. However, such clever leaps are rare because researchers don't tend to spend their time researching fields outside of their expertise. AI can easily hop between fields. BootLoops is a harness that can spot and solve problems in seemingly unrelated fields that share the same mathematical structures at massive scale.
Speaking of TanStack, see also 𝕏 TanStack Markdown + Highlight 1.0: a tiny, fast Markdown renderer for docs and AI streams, with its companion syntax highlighter. Framework-agnostic, comes with a <Markdown> component.
Matt takes a look at CSS Anchor Positioning, namely anchor-name and position-anchor, and how to use them to build tooltips and dropdowns that hold their position through window resizes and page scrolls.
CADCraft: computer-aided design and drafting — an open-source, clean-room AutoCAD-style app in pure Rust
David felt good about Deno in 2021, but has now returned to Node and is surprised by how much has improved. He ported his site generator back with barely any changes, and doesn't hold back on where he thinks Deno went wrong.
A comprehensive library for generating docx files. 9.8 recently added support for charts, shapes and watermarks, and 9.9 adds a way to lay out documents the way Word itself does. Homepage.
Not learning to use AI at this point is detrimental to your career. The tastes and desires in the employment market have changed. Teams that aren't working with AI will be replaced with workers who use AI. The job market might look tough, but it's much easier for workers who have been investing in themselves.

A minimal HTTP framework best known for powering Nitro and Nuxt’s server layer. v2 is a rewrite around standard Request and Response, so one app runs on Node, Bun, Deno and Workers, with URLPattern-style routing and (event, next) middleware. More info here.
