Hi everyone!

Huge thanks ❤️ — we just hit #1 resource on the State of React 2025 survey. Wild.

This week leans heavily into TanStack and Next.js content, plus a few notable releases worth your time.

On mobile, Hermes is clearly ramping up, and ByteDance just lowered the barrier to building Lynx apps.

Let’s dive in.

Hi everyone!

This week, we have a good variety of React content, with great community articles and various releases. Many generative UI solutions are emerging, and I’m curious to better understand how they differ from one another.

React Native 0.84 just dropped, and Gesture Handler 3 is in beta. Expo SDK 55 should also be out soon.

Hi everyone!

You’ll have to get used to it: yet another week filled with AI content. From MCPs to Agent Skills to AI-specific CLIs, we don’t know where to turn anymore.

We’re delighted to be ranked once again among the top 5 newsletters in the State of JavaScript 2025 survey. Thanks for your trust!

By the way, we’d love your feedback — what do you like about the newsletter, and how could we make it better in 2026?

Just hit reply and let us know! ❤️

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!
