🚀 Want to improve your maps in #ReactNative app? Add markers clustering with react-native-maps for a smooth experience. Let's dive into how to set it up in your app! ⬇️🧵

[Jan Koziński @jan_kozinski]

Wow I didn’t know the difference can be so tremendous! Definitely wanna find some time after 0.74 is out to see how it goes with the react-native-maps

[brent @notbrent]

i'm playing around with @reactnative new architecture examples using [email protected] and [email protected], and it's pretty cool to see automatic batching with native event handlers in action.

Can't believe it. I've been trying to bring seamless native API access to React Native for 5+ years, and just tackled the final boss.

We just called an arbitrary UIKit API from JS, on the UI thread, with no native code – thanks to NativeScript, Node-API, and Reanimated. 🥹🚀

[JP ✨ @JPoliachik]

Great example how React Native apps are actually native iOS & Android apps:
I exported a Unity project for Android, dropped the files in /android dir, and can show a <UnityView/> in my React Native app
Anything a native project can do, RN can do - because it _is_ a native project

Hope you’re coming guys, there’s some good stuff to be heard here 🔥 I’m HYPED

[React Native Connection @ReactNativeConn]

If you’re reading this, you’re likely already using tools that are created or maintained by @BWidlarz or @WidlarzGroup, such react-native-video or react-native-maps.
Time for you to thank them with a drink in Paris!

react-native-maps are ready 🫡 make some noise for @lkosmaty for the contribution! 🔥

[React Native @reactnative]

Now is the time to verify New Architecture compatibility in your libraries!

We recommend starting with the Interop Layer, which makes it possible to use your existing library code. It's enabled by default in 0.74

@tomekzaw_ Works pretty well whenever I need to use it. However every time I open it by accident, by computer slows down so much. Is there some AI that detects unintentional clicks to troll the dev even more? 🤣

[Jan Koziński @jan_kozinski]

@AcetyldNL @DanStepanov Camping map is a bit tricky because the library is a wrapper over a google / apple maps. If your camp is shown on google maps than answer is yes. But if it isn't then it's not a best fit for you. You can experiment with custom map overlay, but it's not straightforward

[Jan Koziński @jan_kozinski]

@gabimoncha @DanStepanov @swmansion @expo actually expo recommends using react-native-maps in their docs ;) https://t.co/9frTqyMv2h

@devadam88 Hit the gym, supplement magnesium, don’t sleep more than you need🫡 I’ve been sleeping for 12 hours a day and that made me soo cloggy.

[Jan Koziński @jan_kozinski]

@LinusTech I dunno, he looks kinda sus to me

[Jan Koziński @jan_kozinski]

Flipper brakes builds on iOS 17.4 so don’t update your Xcode if you wanna use it

[Daniel Williams @Danny_H_W]

Of course xcode 15.3 would break one of the react native libraries, never install xcode via the app store, always update it intentionally.

[Oskar @o_kwasniewski]

React Native brownfield integrations on iOS just got way easier! ✨

Introducing `RCTRootViewFactory`, which encapsulates the logic of creating RN root views into a factory pattern.

It's my biggest contribution to React Native, thanks to @CipolleschiR for reviewing 🙏
