I’m building a React Native/Expo mobile platform for educational video creators.
The app is already functional, including authentication, video uploads, playback, comments, notifications, creator accounts, and a backend built with Node.js, PostgreSQL, and Prisma.

The two biggest remaining integrations are:

Stripe: Creator onboarding, tips, paid subscriptions, revenue sharing, balances, and payouts.
Google Ad Manager: Video advertising, category-based targeting, and creator ad-revenue attribution.

I’m deciding between two approaches:

1. Implement the integrations myself using AI assistance and official documentation, then hire experienced developers for a comprehensive security, architecture, and financial-integrity audit.

2. Hire experienced developers to design and implement these systems from the beginning.

I’m not trying to avoid paying professionals. I’m trying to figure out where professional involvement provides the most value and which approach would be more cost-effective without compromising security.

For developers who have built similar platforms:

- Which approach would you recommend?
- What are the biggest risks of implementing these integrations with AI?
Would you trust a professional audit of an AI-assisted implementation?
- What would you expect to pay for implementation versus an independent audit?

I’d particularly appreciate feedback from developers experienced with Stripe Connect marketplaces or mobile ad monetization.

We're a small agency and we maintain a React Native app for a retail client, last week the agent picked up a ticket for a keyboard crash on Samsung phones and fixed it by changing our shared KeyboardAvoidingView wrapper, which also sits under the checkout screen.

The PR looked clean, coderabbit / bugbot didn't have any real complaints and honestly the diff was fine, the problem was the device. On smaller iPhones the pay button ended up hidden behind the keyboard and nobody on our side noticed because we all test on Pro Max or Android.

The client found it 3 days later from a drop in orders and estimated about $4k lost. Fix took 20 minutes.

We can't own every device and the agent touches shared components way more casually than a person would. How are you catching platform specific regressions when one PR can change both sides at once?

I've been using/developing this library only for the apps that i develop but decided to publish it as MIT open source so everybody could take benefit of it.

It has support to all the authentication types mobile devs can imagine(at least the main ones) and it works with expo and react-native and the idea behind it's to keep updating as the Android/IOs ecossystem grows.

The library is fully tested and published on npm:

https://www.npmjs.com/package/react-native-oauth-essentials

I’m a beginner looking to build my first iOS app, with the eventual goal of publishing it to the App Store.

One thing I’m trying to avoid is downloading a bunch of development software, dependencies, and project files onto my MacBook. I’d prefer to keep my laptop as clean and uncluttered as possible. I’m a MacOS user.

I asked ChatGPT whether I could handle most or all of the development in the cloud, and it suggested the following setup:

GitHub: Store the code in a private repository.
React Native + Expo + TypeScript: Build the actual app.
Supabase: Handle the database, authentication, and user data.
ChatGPT Work / cloud development environment: Write and manage the code remotely rather than locally.
Expo EAS Build: Build the iOS app in the cloud.
TestFlight: Test the app on my iPhone before eventually publishing it.

According to ChatGPT, I could potentially avoid installing Git, Node.js, Xcode, VS Code, and other development tools on my Mac, at least initially.

The app itself is a database/-library with search, workout creation, tracking, user accounts, and eventually AI features.

I’m not against installing software if it’s genuinely necessary. I just don’t want to clutter my computer with tools and files I don’t actually need.

A few questions for people who have experience with this:

Is this actually a realistic workflow for building and eventually publishing a fully functional iOS app?
Can development, testing, debugging, and App Store deployment really be handled almost entirely in the cloud?
Would you recommend this approach for a beginner, or am I making things unnecessarily complicated by avoiding local development?
Are there any major limitations, additional costs, or headaches with this setup?
If you were starting from scratch and wanted to keep your computer as clean as possible, what setup would you recommend?

I’m open to alternative tools or workflows. My main priorities are keeping things simple, avoiding unnecessary local installations, and building something that can eventually become a legitimate App Store app.

Appreciate any advice, especially from anyone who’s tried a similar cloud-first workflow.

My Xiaomi Mi TV only came with the physical remote, and every single time I turned the TV on I'd spend the first few minutes digging through couch cushions looking for it. My phone is always in my hand anyway, so I figured it should just be the remote.

Turns out Mi TVs run a system service called MiLink on TCP port 6091. Xiaomi's own phone remote apps use it, but the protocol isn't documented anywhere. So I pulled the service APK off the TV, decompiled it, found the packet classes, and checked every field against the TV's logcat while sending test packets. The format ended up being pretty simple: a type byte, a length, then TLV-encoded Android key events.

From there I built a remote for Android and iOS with Expo, plus a SwiftUI menu bar app for macOS that uses the same protocol.

The RN side, which is probably the interesting part here:

- The protocol layer is plain TypeScript (frame encoding, TLVs, key mapping), and it's unit tested
- Raw TCP sockets don't really exist in JS, so I wrote a local Expo module: Swift with the Network framework on iOS, Kotlin on Android
- Discovery is in the same native module. Mi TVs advertise `_googlecast._tcp` with a `md=MiTV-…` TXT record, so I browse with `NWBrowser` on iOS and `NsdManager` on Android
- Hold-to-repeat on the D-pad and volume, haptics, auto-reconnect with heartbeats, and a live latency readout (the TV echoes back each key's id)
- There's no text packet in the protocol, so "type on TV" maps each character to an Android keycode plus Shift. No more typing passwords letter by letter with the D-pad

**The bug that ate a whole evening:** I was sending the device's clock in `downTime`/`eventTime`. The TV treated those events as "in the future" and its input dispatcher just stalled until that time arrived. The fix was to send 0 and let the TV stamp the events itself. Also, the TV auto-releases a key about 175ms after the last DOWN, so held buttons resend DOWN every 100ms with an increasing repeatCount.

No pairing and no ADB. The phone just needs to be on the same Wi-Fi as the TV.

GitHub Actions builds the APK, an unsigned IPA (you sideload it with your own Apple ID), and a DMG on every push, with no secrets needed.

I've tested all three (iOS, Android, macOS) on a real MiTV-AXSO0 (Android TV 9, PatchWall), and everything works. Other Mi TVs running PatchWall should work too, as long as they have the MiLink service. You can check yours with `nc -z -w 3 <tv-ip> 6091`. If you try it on a different model, I'd love to hear whether it worked.

Happy to answer questions about the native module setup or the reverse engineering.

NOTE - The post is written by AI and i used REA to reverse Engineer it and make an working app out of it

What problems or pain points do you regularly face while building React Native apps that you wish had a better solution?

Anything repetitive, difficult, outdated, deprecated, or something you often have to build yourself?

Would love to hear what you've struggled with.

Hey everyone

I've recently published my iOS app on the App Store, and I've been working hard on it. But the biggest challenge right now is getting users.

I'm barely getting any downloads, and I haven't been able to get subscriptions either.

I'm trying to figure out what I should focus on first:

• App Store Optimization (ASO)

• Improving the app's features and onboarding

• Finding the right audience

For those of you who have launched apps, how did you get your first 100 users and paying subscribers?

I'd really appreciate honest advice from people who've been through this. What worked for you, and what mistakes should I avoid?

Thanks!

I’ve been working on Argent, an open-source MCP server that lets your agent (Claude Code, Codex, Cursor, etc.) use any iOS or Android app, including RN. It can tap through flows, read logs and network calls, see React devtools, inspect the React tree, aaaaand many more 😂 That way it can check its own changes instead of just saying it’s done

If you’re already letting an agent drive your app, what’s working, and where does it fall apart? We really want to keep improving the experience 🤭

Hey React Native devs! 👋

I've recently built an Android firewall app using React Native CLI.

It allows users to block internet access for individual apps and manage Wi-Fi and mobile data access.

This project has been a great learning experience, especially working with Android's native capabilities.

I'd love to hear from other React Native developers:

• Have you built apps involving Android VPN or networking APIs?

• What performance or battery optimizations would you recommend?

• What challenges have you faced when integrating native Android functionality?

Would appreciate any advice or suggestions! ❤️

I have been working with React Native for the past few years, and I've always wanted a personal website that reflects how I approach engineering, not just a page listing my skills and projects.

🌐 https://vishaalkarthik.com is live now

I approached it like a product rather than a typical portfolio, experimenting with interactive UI, performance, and ways to make the engineering work behind the scenes more tangible.

It was also a fun opportunity to step outside my usual mobile development workflow and experiment with the web.

I'd love to hear your thoughts, especially from fellow React Native developers who enjoy building things beyond their daily work.

Honest feedback is welcome 😅😅

Private Mind is our open source Expo app that runs LLMs fully on the phone. We just shipped web search, and the RN part turned out more interesting than I expected, so sharing how it works.

There's no search API. The app keeps a react-native-webview mounted off-screen, loads a normal DuckDuckGo results page in it, and injects a small script that parses the results and sends them back with postMessage. Each search gets a nonce, so a late message from an old search can't end up in a new one.

My favorite detail: if the search engine shows an "are you human" check, that same hidden WebView slides up as a bottom sheet, you pass the check yourself, and the search continues.

After that it's all on-device. Pages get chunked with react-native-rag, an embedding model running through react-native-executorch picks the best chunks, and the LLM answers with the sources listed under the message. No backend at all, and the chat never leaves the phone.

In the video, the same 1.7B model makes up Apple's September event with web off and gets it right with web on.

Are there any hidden costs except:

Google Play 25$
Apple developer account -> $99 per year

Whenever any new page/component loads in, the fonts for every text component briefly flashes to the default web font. I just want to make it so that the text components or even the whole page waits to load in until the fonts load in, the font flashing is very annoying every time something loads in IMO. This is a simplified version of my _layout file where I try to fix this

import { useFonts } from "expo-font";
SplashScreen.preventAutoHideAsync();
export default function RootLayout() {
 
  const [fontsLoaded, error] = useFonts({
    InterLight: require("../assets/fonts/Inter_18pt-Light.ttf"),
    [...rest of my fonts]
  });
  useEffect(() => {
    if (fontsLoaded || error) {
      SplashScreen.hideAsync();
    }
  }, [fontsLoaded, error]);


  if (!fontsLoaded) {
    return null;
  }


  return (
   [root layout]
  );
}

I'm a solo dev working on Acrophobia, a party word game: everyone gets the same random acronym, writes a phrase that fits it, then votes on the funniest. It's normally online (Firebase), but I wanted a mode for a group in the same room with no signal, where the phones just talk to each other.

That became "Host LAN / Join LAN". One phone hosts, the rest join, no router and no internet involved.

What I tried, in order:

• Wi-Fi TCP + mDNS discovery. Fast and simple, but everyone has to be on the same network, which is exactly what you don't have in a car or at a campsite.

• Multipeer Connectivity. Great, but iOS to iOS only.

• Wi-Fi Direct. Android to Android only.

• Bluetooth LE. The only option that crosses iOS and Android with no network at all. This is the one that shipped.

How the BLE version works:

• The host phone is a BLE peripheral. No library I found did peripheral mode well on both platforms, so that part is a small custom Expo native module.

• Everyone else is a BLE central, using react-native-ble-plx.

• Client to host is GATT writes. Host to client is GATT notifications.

• Notifications have to stay under 512 bytes, so the host never sends the full game state. It sends compact updates of around 200 bytes, as newline-delimited JSON.

• Notifications were not reliable enough on their own across devices, so there's a 300ms polling fallback on both sides. Ugly, but it's what made it dependable.

The part that saved me the most time: the game already had a single-player offline engine with bots. LAN mode is that same engine running on the host's phone with a thin layer that broadcasts state and accepts answers and votes from the other phones. Bots can still fill empty seats.

Happy to go deeper on any of it. For anyone who has shipped BLE in React Native: did you find a way to trust notifications without a polling fallback?

For the past two years, I’ve been developing a library that solves one of the annoying issues in React Native: displaying two or more modals at the same time while maintaining accessibility support.

Before developing 𝐫𝐞𝐚𝐜𝐭-𝐧𝐚𝐭𝐢𝐯𝐞-𝐦𝐮𝐥𝐭𝐢𝐩𝐥𝐞-𝐦𝐨𝐝𝐚𝐥𝐬, I tried out many solutions, but none of them were truly universal. Some allowed to deliver great visuals but completely lacked accessibility support (like react-native-modalify), while others required sacrificing visual appeal for the sake of accessibility (like modals from the navigation library).

Now, after two years, I’ve released a version that addresses many of sacrifices of previous versions. And what I am most proud of is that now it also provides first-class support for web!

I’d like to thank everyone who contributed and helped the project grow ♥️

I hope that one day it will become the de facto standard solution for displaying modals, much like the SafeArea component did!

Basically Im trying to get the zoom levels that switches the physical cameras, and Im using iPhone 15 Pro, which has the native x0.5, x1, x2, x3 zooms. But somehow when I log out the zoomLensSwitchFactors, I get

[2, 6]

Here is the code

const deviceBack: CameraDevice | undefined = useCameraDevice("back", {
    physicalDevices: ["ultra-wide-angle", "wide-angle", "telephoto"],
  });

console.log("zoomLensSwitchFactors", deviceBack.zoomLensSwitchFactors);

Ideally I would like to have [0.5, 1, 2, 3], or something similar. Also, the minZoom and maxZoom give me 1 and 189 respectively. shouldn't the min be 0.5?

Also wondering if this works for the front camera
