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.

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

This edition is special for at least four reasons:

1. It's a very rounded anniversary edition - issue 256 - let's hope our counter can hold more than 8 bits 🤞
2. This is the first newsletter issue for Filip, who is improving React Native DX by developing Radon IDE.
3. It was a great week, with a lot of excellent content emerging from the Next.js conf in the React world.
4. React Native isn't far behind, as this week saw some cool stuff released, including updates for React Navigation, Uniwind, React Native Screens, and more.

That's more than enough reasons to jump straight into the content - enjoy the reading!

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 cricitisms 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 newsletter: Armand Petit helped me on the React Native section.

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

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.

Also check our partner conf 🇬🇧 React Native London on 13-14 Nov, and make sure to claim a 10% discount with our usual code "TWIR".

Let’s go!

Hi everyone!

This week is a big one: we barely had time to recover from last week's React 19.2 release, and now React Conf is happening live with another bunch of exclusive announcements!

I'll let you discover it all for yourselves below, enjoy!👌

Hi everyone!

Wondering why the newsletter is late this week?
Well, we had good reasons!

React v19.2 has just been released with the highly anticipated <Activity> component, useEffectEvent hook, and more!

React Native also had exciting updates, notably an OS from Amazon with first-class React Native support, and upcoming solutions to integrate even more tightly with native platforms.

Don't forget that React Conf starts next week, on October 7. The schedule is online, full of interesting talks, and we can expect more exciting announcements!
