🌐 Read Online Hi everyone! Filip and Krzysztof from Software Mansion here! πŸ‘‹ 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...

🌐 Read Online 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 content to check with Fate, TanStack Alpha, React Grab, and more. It’s even hotter on the React Native side. We were patiently waiting for 0.83 to publish πŸ˜‡ and it’s now out. You can now use <Activity> in React Native πŸ”₯. Reanimated 4.2 is also out with Shared Elements...

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 πŸ˜…) Don’t forget to answer the State of React 2025 survey while it’s still open! As always, thanks for supporting us on your favorite platform: πŸ¦‹ Bluesky βœ–οΈ X...

🌐 Read Online Hi everyone, Seb here! πŸ‘‹ 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 πŸ˜†! 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...

🌐 Read Online Hi everyone! Filip and Krzysztof from Software Mansion here! πŸ‘‹ 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 🀞 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...

🌐 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. Let’s also welcome a new co-author of this...

🌐 Read Online Hi everyone! Krzysztof and Kacper from Software Mansion here! πŸ‘‹ We don't know about you, but we're still living and breathing the news from last week's React conf. In the previous issue, we covered the first day of React Conf, but when it comes to React Native, many announcements took place on the second day, including VirtualView and the sneak peek into React Native 0.83. Aside from React conf announcements, Next.js 16 has been released in beta, and Remix 3 has been introduced....
