Hi everyone, Seb and Jan here 👋!
This week, RedwoodSDK 1.0 dropped, and other meta-frameworks improved their SSR performance. A bunch of content related to Async React and the TanStack too!
On the React Native side, Expo UI support for Jetpack Compose is quite exciting. A new animation library could also be an interesting alternative to Reanimated CSS transitions.
Temporal has finally reached stage 4! We also have great announcements from the Vue.js conf that remain relevant for React developers, notably Vite 8.
Let's dive in!

⚛️ React
The former RedwoodJS meta-framework has pivoted to RedwoodSDK, and it now has its first stable release. This time, it bets on Vite, React Server Components, and Cloudflare (using Durable Objects for its useSyncedState() realtime feature). It promises explicit APIs for clarity (no convention, no magic behavior) through composable web-based primitives.
The choice of being tightly coupled to Cloudflare might surprise you, but they explain it in this article. They are building abstractions on top of Cloudflare Bindings and Durable Objects to become service-agnostic while remaining platform-optimized. Similarly, Evan You has recently announced Void.cloud – a Vite-native deployment platform based on Cloudflare – and explained that “the lock-in is what makes the DX possible”. Time will tell how this story compares to Next.js and OpenNext 🤪.

- 📜 Why we banned React's useEffect - The Factory team chose to forbid direct usage of
useEffect()through an ESLint rule, reducing bugs and complexity. Its usage often compensates for something React already gives better primitives for. - 📜 Two React Design Choices Developers Don’t Like—But Can’t Avoid - Ryan Carniato explains why React defers state updates and has an effect dependency array. While designing Solid 2.0, he realized that the Async world has constraints that even signal-based frameworks need to take into consideration.

Make your logs queryable, not just readable
console.log("here")doesn't cut it in production. Structured logs do.
Use this tutorial to connect LogTape + Sentry and make every log searchable, queryable, and connected to your traces. When something breaks, you'll get the full picture: log events, error context, and Session Replay, all linked by trace ID.
- Filter by user ID, order ID, or any custom field
- Attach context once, inherit it everywhere
- Alert when log patterns spike before users notice

Expo UI in SDK 55 - Jetpack Compose now available
Expo SDK 55 brings major updates to Expo UI, moving Jetpack Compose support to beta and refining SwiftUI APIs to match Apple's official conventions more closely. Instead of reimplementing native components in JavaScript, Expo UI exposes the native UI frameworks directly to React Native.
-
Jetpack Compose support: now includes enough Material Design 3 components (like
LazyColumn,ModalBottomSheet, andDockedSearchBar) to build complete apps, which was validated by building a full Wikipedia clone. -
SwiftUI: now it feels like SwiftUI: renamed and restructured SwiftUI components to match their SwiftUI counterparts.
DateTimePickeris nowDatePicker,Switchis nowToggle, andCircularProgressis nowProgressView. -
Familiar API surface: It uses React's compound component pattern (e.g.,
ListItem.Leading) to express Compose's composable lambdas in JSX, and aligns the modifier system so it works consistently across platforms. - AI-Friendly: Because the APIs intentionally mirror native Compose and SwiftUI documentation, AI assistants can easily generate correct Expo UI code relying on their existing native training data.
React Native Ease - Lightweight declarative animations powered by platform APIs
New animation library designed to handle simple transitions with maximum performance. While Reanimated is incredibly flexible, it runs JS on every frame on the UI thread, which can be overkill and cause flickering if the thread lags. react-native-ease solves this by leveraging Core Animation on iOS and Animator on Android directly, resulting in zero JS overhead.
-
CSS-like API: Offers a highly simplified, declarative API inspired by CSS transitions. You simply wrap elements in an
<EaseView>component and pass ananimateprop. - Built for the basics: Perfect for non-layout properties like opacity, transforms, background color, and border radius. It prevents the need to create hundreds of shared values just for simple press animations in lists.
-
AI Migration Skill: It includes an AI agent skill that can automatically scan your codebase, identify simple Animated/Reanimated implementations, and migrate them over to
react-native-ease.
- 💸 Make React apps fast where it actually matters. Learn how to diagnose real bottlenecks and fix slow, janky React apps using modern React 19 patterns.
- 📜 The next generation of Expo APIs: MediaLibrary and Contacts - Following the Filesystem update, Contacts and Media Library are getting the new object-oriented API treatment. The use of Shared Objects and Shared Refs offers better performance and simpler querying through deeper native module integration.
- 📜 Handling Navigation in React Native Brownfield Apps - Navigation for brownfield apps can be tricky.
@callstack/brownfield-navigationaims to simplify this process by wiring navigation in a clean, typed, and maintainable way. - 📦 Keyboard Controller 1.2 - Chat Scroll View - Tackles layout thrashing during keyboard animations. This related article explains why Flutter and React Native suffer from the same keyboard animation stutter.
- 📦 Fast Flow Transform - Strip Flow types 20x faster than with Babel - This tool might help remove Babel entirely from your React Native pipeline and adopt a full Rust-based toolchain. Note that SWC is also working on Flow types stripping.
- 📦 React Native Sandbox 0.5 - Now supports Android - Allows you to run multiple, isolated React Native instances within a single application
- 📦 Agent Device 0.8.4 - Screenshot diff support - CLI tool for pixel-level image comparison.
