It also describes Swift-to-WebAssembly progress and a Cloudflare full-stack demo using shared message types. ### Source excerpt Welcome to "What's new in Swift," a curated digest of releases, videos, and discussions in the Swift project and community. Here's an update from guest contributor Simon Leeb on Swift's progress as a language for web scenarios: Hi, Simon here! I am the creator of the elementary-swift project, a collection of packages born from a simple wish: I want to build web UIs in Swift and ultimately help Swift become a first-class choice for the web. This journey began after I started using Swift for backend services. The web frontend, however, still lived in a separate ecosystem, and I really wanted it to feel as ergonomic, safe, and efficient as the Swift I was writing everywhere else. That led to the creation of Elementary: a modern and efficient HTML rendering library with a familiar declarative API, built for the web. It integrates easily with frameworks like Vapor and Hummingbird, and has become a practical option for server-rendered web UIs. Around that same time, years of community work in the swift-wasm project made compiling Swift to WebAssembly increasingly viable, while Embedded Swift was taking its first experimental steps. This made me wonder: "How hard can it be to use Embedded Swift and build a state-driven web UI framework that produces tiny WebAssembly binaries?" Turns out: quite hard, actually! But it was too late. Despite my better judgment, I was in the middle of creating what is now known as ElementaryUI. Where Elementary renders HTML on the server, ElementaryUI runs in the browser itself. You can watch my talk at Swift@FOSDEM 2026 if you want to know more about the why, what, and how. To showcase where the project is heading, I recently posted a small Full-Stack Swift on Cloudflare demo. It features Swift in the browser communicating with a Swift backend on an edge worker through shared message types. I hope it gives people a concrete sense of how much the core technologies and the surrounding tooling have advanced. ElementaryUI is still young, with plen ## How Turbopack chunks your JavaScript DevFeed: [How Turbopack chunks your JavaScript]() Original publisher: [Read original article]() Author: Sam Poder Published: 2026-09-03T16:00:00Z Content type: article Language: en Sources: [Next.js Blog]() Topics: [modern web development](), [Web Development](), [web applications]() Tags: [cache](), [code](), [compression](), [http](), [javascript](), [next-js]() ### AI overview The article explains how Turbopack groups JavaScript into chunks for Next.js applications.

It centralizes Shopify API utilities, cart state, and server-side integrations while supporting frameworks including React, Next.js, Nuxt, and Svelte. ### Source excerpt Hydrogen made headless storefronts easy to ship, but not portable. At Vercel Ship 26 in New York, we announced that we are working with Shopify to rebuild it from the ground up, a shared bet on a more open web. The new version is open source and runtime agnostic, meaning it can run anywhere JavaScript does. You can build with Svelte, Nuxt, Next.js or even bring your own custom framework. Our strategy includes three layers: core, client and server. The core Core is the JavaScript we all used to write for the Shopify API, and never shared. Now it lives in one place. Take formatMoney. The open web already solved most of this with Intl.NumberFormat. But the Shopify API doesn't hand you a number. It responds with a custom type, MoneyV2, and the amount is a signed decimal number serialized as a string. The result is the same, but you're not writing or maintaining the glue code anymore. When the API changes, the upgrade is trivial. Centralize the core and you fix each bug once, ship improvements to everyone, and get back to building. The client Rendering what the core returns involves the same repeated decisions. Cart state is the obvious one. Anyone who's built a commerce app has written a version of this. Different code every time, all chasing the same things. With Hydrogen, the client layer now handles the cart. State management becomes one import. Centralize this and you get the best practices for free, so you can spend your time on the parts that are actually yours to build. It's available for React today on the Hydrogen preview branch, with more frameworks coming. The server Developers need full-stack access to build storefronts that scale without sacrificing performance. Static content should serve instantly from a CDN while dynamic data like inventory streams in. The open-source community solved this with frameworks like Next.js, Nuxt, and SvelteKit: full-stack capabilities with no lock-in to a proprietary runtime. Say your storefront caches product queries with on ## Modern CSS theming with light-dark(), contrast-color(), and style queries DevFeed: [Modern CSS theming with light-dark(), contrast-color(), and style queries]() Original publisher: [Read original article]() Published: 2026-06-22T00:00:00Z Content type: tutorial Language: en Sources: [Una Kravets]() Topics: [CSS](), [modern web development](), [color](), [Media Queries]() Tags: [color](), [css](), [dark-mode](), [dynamic-theming](), [media](), [scheme](), [support](), [themes]() ### AI overview This tutorial explains how to combine light-dark(), contrast-color(), style queries, custom properties, and related CSS color features to create adaptive themed components.
