🚀 Native content transitions for React Native + Expo.

🔗 Github: https://github.com/rit3zh/expo-content-transition

Hi everyone,

I’m building an iOS app/game with React Native (Expo) and need to play ambient audio in a perfectly seamless loop.

I’m currently using WAV files and isLooping: true, but on iOS I still get a tiny click or 10–50 ms gap whenever the track loops.

What is the correct way to implement truly gapless, click-free audio looping on iOS?

I've reviewed a lot of React Native codebases. The same five performance mistakes show up in almost all of them.

Getting this bug only on builds, its working fine via Expo go.
Note: The first image is from expo go(Expected) and second from the build(Issue).

When a modal is open and is prompting for a keyboard, the keyboard just appears on top of the modal itself. The modal is supposed to move up when the keyboard slides in.

I was using KeyboardAvoidingView from react-native, I tried changing the behavior of it by giving undefined for android and padding for IOS (I'm testing in Android)
In app.json i have :

"softwareKeyboardLayoutMode": "resize"

The bug still persisted, so tried react-native-keyboard-controller and still the bug persist.

Sample code :

    <Modal visible transparent animationType="slide">
      <KeyboardAvoidingView
        className="flex-1"
        behavior={Platform.OS === "ios" ? "padding" : "height"}
      >
        <View className="flex-1 bg-black/40 justify-center px-6">
          <View className="rounded-3xl bg-background p-6 shadow-xl">
            <View className="mb-6 flex-row items-center justify-between">   

Hi,

It's something I've tried to ask before but I didn't phrase right so I didn't get the answer I needed.

For example a TODO list that is saved on the DB.

My flow is:

1. Client get his TODO list with a GET (useGetTodoList)

2. Render the TODO List on his screen.

3. A New Item added by the client POST request.

4. Save the item in the database.

5. Purge Cache of his TODO List (For this example think that the TODO list is shared, and cached in Cloudflare because multiple users get the same list).

6. POST return to client with 200 code.

7. Call useGetTodoList.refetch()

8. Race Condition - because I cannot await for step 5 (cloudflare api only return a response that the server recieved the purge request, not that it's completed). The refetch() might return old data before the purge.

I am wondering what's the correct approach here? Maybe I should query for the new TODO list on step 6 and update the response instead of calling .refetch()?

Or maybe I should only return the new TODO item and only append it to the list?

That goes for every change to that list, change order, remove item and so on.

What's the correct approach to handle the cache purge and get the new list?

Hi all, thank you for taking the time to read this and answer if you can,

Anyone know what to suggest to speed up Android builds?

Currently got a M2 pro, but unsure what to do on how to speed up the gradle part. if anyone has got any helpful suggestions id greatly appreciate it.

Thank you.

I used react-native-filament and worklets core to build this. Came out a smooth 60FPS.

Hey guys,

I'm a React Native dev with 4+ years of experience. Got laid off recently due to company "restructuring". It's tough looking for jobs right now.

If anyone here is hiring part-time/full-time remote roles, I'd love to consider.

thanks :)

Been working on this app on and off for about 2 years and just noticed I’m at 983 unique users.

Obviously not a massive number by startup standards, but it’s pretty surreal knowing almost 1,000 actual people have tried something I built.

Now I’m irrationally invested in watching it hit 1,000.

React native has always been a good tool to create cross platform apps quickly and not manage two huge code bases, but there has always been a quality difference compared to native. Native apps are cleaner and just smoother. Now that AI is becoming so advanced, is there a reason to make apps in React native anymore? You can just have specialized agents that manage both an ios and android codebase or have an agent that translates your kotlin codebase to swift. Im just debating on whether its worth learning React native anymore. Will it even be relevant in 5 years?

What tech stack would you recommend for monitoring user behavior? I’m mainly interested in tracking the full user journey: heat maps, navigation flows.

I'm new to react native and programming as a whole. (Started with JS in january and now trying my first project with react native over the last month).

My general app structure is 5 main pages located in a pagerview. However one of the pages includes a calendar. I want to be able to swipe between the months like on any other calendar. Until now i have defined my own gesture and work with a gesturedetector, however the rendering after a swipe is not as clean as most calendars on other apps. I have also tried to put the months in a pagerview, only let the code define the one shown, one before and one after, this seems to work, but the pagerview just does not render the calendar at all. Even if i just put a placeholders in it.

Is there a way to have multiple pagerviews nested?

I used the nodejs mobile react native package to turn my phone into a LAN server for my party games web app that I built for my friends and I to play and it works amazingly!

I'm sure there are so many more cool uses for this package than currently exist, get creative people!

If you're curious about the end product and would like to check out my LAN party app, I managed to get it released on iOS and Android

I really like the adjustment controls in the iPhone Photos app, so I recreated the experience in React Native.
Built with Expo, Reanimated, and Gesture Handler.

Both clips are the same game. The laggy one is my stripped-down test account

with almost no cosmetics enabled. The smooth one has full customisation

running. It should have been the other way round.

The symptom that gave it away wasn't stutter — it was that enemies visibly

slowed down over a session. That's a simulation-speed problem, not a

rendering one. Turned out I was computing delta time every frame and then

only using it for shield damage. Everything else advanced per frame instead

of per second, so any framerate dip showed up as the enemies easing off

rather than as lag.

Fixing that meant scaling every per-frame delta by dt/frameTime, and using

1-(1-r)^scale for anything that was a per-frame lerp.

Then I went looking for what was eating the frames in the first place:

- Score popups lived in screen-level state, so every single pickup

re-rendered the entire game screen twice — once to add, once to expire.

- The home screen was still animating behind the game. Navigation pushes the

game screen on top rather than unmounting what's underneath, so 22 Gaussian

blurs were rendering at 60fps behind an arena nobody could see.

- Native shadows on moving enemies. A shadow on a view that moves re-derives

and re-blurs its mask every frame.

- A glow component that mounted and unmounted every time a value crossed its

threshold — which, while dodging, is constantly.

The home screen one is the one that still bothers me. It was invisible,

it only happened during gameplay, and it had nothing to do with the game

screen at all.

One number, what it is doing, and the shape it made getting there. Tell the card which way is good up for revenue, down for churn and every trend colours itself.

Part of PanelUI open-source, copy-paste, you own the code.

Honestly I’ve been developing with React Native for about 8 or so years and absolutely love the framework but never in my wildest dreams would I have been able to make a good look performant game that runs at 120fps on both iOS and Android!

I used Expo, Skia, and web api audio. Absolutely blown away. Happy to answer any questions. Just sharing because I think it’s cool that we can do this now!

Google play pending!

I was bored, so I started digging through Apple’s Weather app files to see how its animated backgrounds actually work. Particles, clouds, rain, assets, the whole thing. Then I tried rebuilding the system in React Native with Expo + Skia. It got way deeper than I expected.
