in a modern web app there are many potential causes of a performance problem: third-party JavaScript, overburdened servers, bloated assets, missing database indexes - a list as long as your arm. But decades of building for the web told me that this was a frontend problem. I could just smell it. The page looked janky while loading. And despite being the least-bad approach for web frontends today, the React ecosystem is lousy with ways for a codebase to get tangled, slow, and fishy.

The web is full of AI assistants that appear to understand application UIs, user data, and intent. In practice, however, most of these systems operate outside the application itself. When you try to build one from scratch, you quickly run into a core limitation: large language models have no native understanding of your React state, component hierarchy, or business logic.

Hi everyone! This week, we saw a lot of activity on X about the new AI skills system. Personally, what excited me most is the new Firefox release that unlocks interesting things for React developers. The React Native ecosystem is also super active, with many interesting releases. And I'm sure Expo 55 beta will drop just after we send our email 😅, so make sure to check their blog because it's coming soon. Don't miss the next email! As always, thanks for supporting us on your favorite platform:

How does generation work? (Does it generate source code?)Generated UIs must be secure, reusable and cacheable. As such, syntux does not generate source code. It generates a schema for the UI, known as a "React Interface Schema" (RIS). See the question below to get a better understanding. This schema is tailored to the value that you provide. It is then hydrated by syntux and rendered.

Apple's Liquid Glass UI for iOS 26 is getting a lot of attention. Beyond the visual hype, it is also raising questions about accessibility and usability. Developers, however, are already trying to recreate the effect for the web and mobile interfaces. On iOS, Liquid Glass is backed by a rendering engine designed to generate high-fidelity, physics-like glass patterns efficiently. Web browsers do not expose this kind of native abstraction, but we do have SVG filters, which are powerful enough to approximate the same effect.

At React Advanced 2025, Aurora Scharff presented Building Interactive Async UI with React 19 and Ariakit and shared how ARIAKit, an open-source accessibility library, enables developers to build custom UI components that meet WCAG standards without requiring deep accessibility expertise. The presentation showcased a practical approach to combining ARIAKit's unstyled primitives with modern React patterns to create production-ready, accessible interfaces.

Build an AI assistant with Vercel AI Elements, which provides pre-built React components specifically designed for AI applications.

Vitest, by introducing its Browser Mode, allows tests to run in an actual browser context, enhancing reliability and realism in UI testing.

Goldfish Ads, established for 9 years, has developed a unique planning tool for Media Agencies and Brands to run Digital Out-of-Home campaigns.

The WebSocket protocol offers persistent, real-time, full-duplex communication between the client and the server over a single TCP socket connection.
