Hi everyone!

This week, the community continued to publish React-related Agent skills. React RSCs and Next.js are hit by another set of DoS vulnerabilities, and it’s recommended to upgrade immediately.

The React Native side is more exciting, with Expo SDK 55 in beta and upcoming support for new CSS features. We now have 2 distinct libraries implementing home screen widgets, and need to understand the trade-offs of each approach.

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.

Hi everyone! Kacper and Filip from Software Mansion here! 👋

It's not too late—we're finally back from our Christmas break, and the entire newsletter team wishes you a happy New Year!

The winter break brought a lot of great articles from the community. While for some, early January is a time for reflection, summaries, and reviews of 2025, others can’t stop shipping.

In the React space, we have a new version of Next.js 16.1, security fixes for React Router, and the announcement of Waku 1.0 alpha.

As for React Native, we have the release of Voltra, a new way to create Live Activities & Widgets, and a sneak peek of React Native 0.84 with Hermes v1 enabled by default.

Hi everyone! Filip and Krzysztof from Software Mansion here! 👋

It’s been another challenging week for the React ecosystem. Developers worldwide have been rushing to update their React versions to patch two new vulnerabilities. This serves as a good reminder for all of us to prioritize security during testing.

Fortunately, React Native remains mostly unaffected by these threats, as Server Components aren’t yet widely used in the mobile environment.

We are taking a well-deserved Christmas break 🎄 so this will be our last issue until January 14th.
Merry Christmas and a Happy New Year to everyone! Thank you for reading our newsletter throughout the year. See you in 2026! 👋

Hi everyone!

This week, it remains important for me to raise awareness about the React Server Components vulnerability, since an exploit is now widely available. Thankfully, we also have more positive React news!

It’s even hotter on the React Native side. We were patiently waiting for 0.83 to publish 😇 and it’s now out. You can now use <Activity> in React Native 🔥. Reanimated 4.2 is also out with Shared Elements Transition support 🔥.

It’s the survey season, don’t forget to answer the 2 most important ones that are currently open:

• State of React
• State of React Native

Hi everyone!

A major React 19 Server Functions vulnerability has just been disclosed. Make sure to upgrade your React 19 or meta-framework ASAP!

On the mobile side, we have more positive news: RNRepo should speed up our React Native builds even more, and Shared Elements Transitions are coming soon! (unlike React Native 1.0 😅)

Don’t forget to answer the State of React 2025 survey while it’s still open!

Hi everyone! Kacper and Tymek from Software Mansion here! 👋

This week, TanStack Pacer debuts in Beta, a new framework-agnostic library for controlling function timing with a dedicated React adapter. Lots of interesting articles featuring a 20,000x improvement in TanStack Router route matching algorithm speed, tips to speeding up Next.js on Kubernetes, and tutorial for React 19 Actions for better component responsiveness.

On the React Native side, we'd like to highlight an incredibly detailed blog post on Vercel's breakdown of building the v0 iOS app.

Enjoy the read!

Hi everyone, Seb here! 👋

It's been another quiet week in the ecosystem, probably because everyone was afraid to announce anything during the massive Cloudflare outage! By the way, this one was not caused by useEffect 😆!

We have a good variety of interesting links, but I’m not sure what could be the headline. The most important news was probably the announcement of the upcoming CSS grid support in Yoga and React Native, but it’s still a draft PR for now. Also excited by the TC39 proposals progressing.

Make sure to take the State of React 2025 survey, which just opened today!

Hi everyone, Seb here! 👋

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!

Hi everyone, Seb and Armand here! 👋

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.
