This week has been relatively calm in the ecosystem. We have a good variety of community blog posts, releases, and weak signals. I'm not sure what to highlight, so I'll just let you enjoy reading it!
As always, thanks for supporting us on your favorite platform:
A collection shouldn't dictate what data loads: Your queries should. This concept is now implemented in TanStack DB with a new syncMode: βeagerβ | βon-demandβ | βprogressiveβ option. This moves the library closer to how GraphQL clients like Apollo/Relay work, where components declare their data dependency, and the client figures out how to load and maintain that data. This can be adapted to work on top of any existing backend API, as long as you provide code to map the query predicates into actual API calls.
π£ Both Bun and Vercel announced TanStack Start support, leveraging the Nitro Vite plugin.
π Next.js PR - New config.experimental.transitionIndicator option: This turns on an experimental React Transition Indicator feature to trigger your browser's native spinner during pending React transitions. Itβs still early, and should only work in Chromium, but Iβm excited to give it a try asap!

π React 19 Error Boundary Behaves Differently: Explains a subtle Error Boundary behavior change that came with React 19, implementing a fail-fast behavior that bails out on the first error instead of aggregating errors.
π Dead Framework Theory: New frameworks are dead on arrival in a world where React has become the platform. LLMs output React code by default and/or due to hardcoded system prompts, creating a self-reinforcing loop that hinders innovation.
π Vercel: The anti-vendor-lock-in cloud: Vercel argues that a framework-defined infrastructure creates more portable code and less lock-in. Next.js adapters formalize the framework-platform contract.
π Don't Blindly Use useTransition Everywhere: An interactive blog post explains that the UX of a React docs example is not ideal (switching tabs with expensive content), and suggests an improvement.
π Error Handling in React with react-error-boundary: The lib provides a declarative error boundary component for rendering errors, and you can also use useErrorBoundary() to trigger it imperatively.
π¦ ImGui React Runtime: Hermes maintainer created a custom runtime and React renderer for Dear ImGui (C++ GUI lib). Experimental, but clearly shows Static Hermes' ability to mix typed and untyped JS in a single project, while enabling direct, zero-cost FFI bindings to the underlying C++ lib.
No more switching between your terminal and browser dev tools. Console Ninja brings your runtime logs, errors, and variable values right into VS Code, Cursor, Windsurf (and other VS Code editors), exactly where they happen in your code.
See live console.log output right next to your source code, filter messages, and instantly spot issues without breaking your flow. Works seamlessly with Vite, Next.js 16, React Native (iOS and Android), Astro, and more. Upgrade your AI agent π€ with real-time runtime insights for smarter debugging.
Snapchat released a beta version of the cross-platform UI framework they've used in production apps for the last 8 years. Itβs not based on React, but also uses a similar declarative model and relies on the Yoga layout engine. TypeScript components are compiled directly to native iOS, Android, and macOS views.
π¦ Szymon Rybczak on the recent React Native CLI DevServer vulnerability: This remote code execution vulnerability was unfortunately not disclosed responsibly. It only impacts 0.80/81, for which the security fix has been backported as soon as possible. Make sure to upgrade!
π Read Online Hi everyone, Seb and Armand here! π This week, we found various interesting React releases and links about directives, Partial Pre-Rendering, performance, micro-frontends, i18n, among other things. On the React Native side, we had 2 major releases and various interesting weak signals. Beware of the RN Dev Server vulnerability, and make sure to upgrade if needed.

π Read Online Hi everyone! Filip and Krzysztof from Software Mansion here! π This edition is special for at least four reasons: It's a very rounded anniversary edition - issue 256 - let's hope our counter can hold more than 8 bits π€ This is the first newsletter issue for Filip, who is improving React Native DX by developing Radon IDE. It was a great week, with a lot of excellent content emerging from the Next.js conf in the React world. React Native isn't far behind, as this week saw some...
π Read Online Hi everyone! This week, we have a lot of interesting content about Next.js, with a new major release dropping just before their flagship conf. But also fair criticisms showing that not everyone is satisfied with the framework. On the mobile side, React Native developers will enjoy improved support for iOS 26 and the ability to provide native iOS header items. BottomTabs is now v1, and Solito v5 dropped with a paradigm change. Letβs also welcome a new co-author of this...
