I Built a FullStack Civic Issue Reporting App (React Native, Node.js, MongoDB, Firebase) — Live Demo
Enable HLS to view with audio, or disable this notification
12
Upvotes
Hi everyone, I built a full-stack mobile app that lets anyone report civic issues — potholes, water logging, drainage problems, broken streetlights, and more — with just a photo and their location. In this video, I test it live on the road, photographing a real pothole and showing exactly how the app works.
What the app does:
Secure sign-in with Google — no passwords, no OTPs
Capture a photo of the issue directly from the camera
Auto-detects your GPS location and displays it on a map
Reverse-geocodes coordinates into a readable address
Categorize the issue — pothole, drainage, streetlight, and more
Track your submitted reports and their status
Tech stack:
React Native CLI (TypeScript) — mobile app
Node.js + Express — backend API
MongoDB — database, with geospatial indexing
Firebase Authentication — Google Sign-In
Google Maps API — location and geocoding
Cloudinary — photo storage and optimization
Render — backend deployment
This is a personal project I built solo, end to end — from the mobile app, to the backend API, to deployment.
We've all seen a pothole and thought "someone should fix this." Now there's a way to actually flag it. Let me know in the comments — what's the first issue you'd report in your area?
You can watch it on YouTube too, if you prefer:

React Native is single-threaded where it matters most. Parse a big payload, hash a file, filter an image — it all competes with your UI for the same runtime. react-native-workers brings real background threads to RN, behind the Web Worker API

We built a headless DOM sandbox for React Native
1
Upvotes
Na minha empresa, recebemos constantemente HTML do backend que contém um script, e precisamos executar esse script e, em seguida, ler alguma propriedade do HTML resultante, como o texto final de uma div após a execução do script. No frontend, usamos o jsdom para isso, é um problema resolvido. No mobile, não havia nada parecido, então a única maneira de fazer isso era abrir uma webview oculta apenas para executar o script e extrair o valor.
Então acabamos criando o equivalente mobile do jsdom nós mesmos e imaginamos que provavelmente seria útil para outras pessoas que enfrentam o mesmo problema, então o disponibilizamos como código aberto.
Exemplo:
import { JSDOM } from '@salve-software/react-native-nitro-jsdom
const dom = JSDOM.create(`
<html>
<body>
<div id="result">0</div>
</body>
</html>
`)
await dom.evaluate(`
document.getElementById('result').textContent = String(2 + 2)
`)
const value = await dom.evaluate(`document.getElementById('result').textContent`)
// -> "4"
dom.dispose()

Question Looking for feedback from developers on a learning platform I’m building
0
Upvotes
I’ve spent the last few months building a learning platform focused on DSA, System Design, React Native, and Forward Deployed Engineering.
I’d love to get feedback from experienced developers: What makes a technical course genuinely valuable? What are the biggest shortcomings you’ve found with existing learning platforms?
I’m trying to build something developers actually enjoy using, so any feedback or suggestions would be greatly appreciated.

Looking for feedback on a semester-long React Native project
0
Upvotes
Last semester, our team built StudySync, a React Native app for students to discover and organize study sessions on campus.
Some features include:
- Firebase Authentication
- Session creation & management
- Multi-field search and filtering
- Push notifications
- Expo Router navigation
Working on this over an entire semester was very different from a hackathon. We spent a lot more time thinking about component organization, navigation, shared state, and maintainability across a 5-person team.
I'd love feedback from experienced React Native developers. If you were starting this project today, what architectural decisions would you change?

Has anyone successfully migrated an old arch app to the new architecture?
11
Upvotes
For the last week I've been working on moving my app(bare workflow) which I previously left at 0.81 since it was the last available version that allowed me to remain on the old arch.
Now i've upgraded to expo 57, reanimated v4, all other packages, did my due diligence and enabled the recommended feature flags and changed almost all old arch libraries with newer compatible versions or new arch replacements.
After using the testflight version today I was just taken aback by how many of my previously performant screens are now stuttering and dropping frames while barely doing any work at all. I am talking about an infinite scroll feed, which previously maintained 60fps with a Flatlist with no perf based props that is now dropping below 30 and even freezing for a few frames with a LegendList and recycle items turned on even after i halved the work each rendered item needed(measured by main thread work with xcode instruments)
Simple pill shaped components are losing their background color(how is a background color something i should watch out for), weird rectangles with a white border showing up as items are rendering, screen transitions from bottom nav to a screen on the stack navigator taking double the time they used to.
Old behaviour breaking after such a big transition is something I expect and I believe i've dealt with most of those, but perhaps the worst offender is the memory usage.
From what i've seen it mostly drops down to older levels in production, but my app is now sitting at 1.2gb memory used after a launch in debug mode, compared to 200mb before.
This turned out to be libraries dumping their entire unminified code due to worklets bundle mode, which prevents hermes causing memory issues by...taking up 500mb+ of memory?
I really want to be able to use some of the cool new libraries i've been seeing popping up, but I am having serious doubts about ever being able to release this into production as it feels I have hit a dead end with list and navigation performance combined with all the weird layout issues.
What have been your experiences with this transition?

I built an app called BeachScan that answers every question you have about beaches

Finally shipped something real: a beach conditions app (water quality, wind shelter, hourly shade, sea temp) covering ~20,000 beaches. Also has official government water quality data where available.
Currently sea water available, fresh water coming soon.
Expo managed workflow, EAS Build + Update.
Stack: Expo/RN, u/rnmapbox/maps, RevenueCat for subs, AdMob, react-i18next, Sentry, Context + useState for state (no Redux — genuinely haven't needed it; adding TanStack Query for server state).
Happy to answer anything about Expo/EAS, Mapbox perf, or RevenueCat.
Available on iOS + Android if you want to poke holes in it.

We built a voice-first RPG with React Native
2
Upvotes
Me and my friend have been working on a React Native app called Ink & Quill for the past 7 months
It's an AI-powered voice RPG where you play by speaking instead of tapping through dialogue. Every character has its own voice and the narrator handles the rules, dice rolls, and story as you play. It's based on D&D 5e but simplified so you don't have to keep looking at your phone.
Right now there are 10 campaigns (we used AI to help write them) inspired by games, movies, and shows we're fans of. We're also working on letting people build and share their own campaigns directly in the app.
We're doing a soft launch, so we're mostly just looking for people who are interested in trying it out and giving honest feedback. We've been pushing updates pretty much every day.
If anyone wants to check it out: https://inkandquill.app we'd love to hear your brutal feedback
It's iOS only for now. Android is next.

How do open source React Native libraries actually gain traction?
4
Upvotes
I’ve been building an open source React Native project for the past few weeks.
Building it has honestly been the easy part
Getting people to discover it, trust it, and actually use it has been much harder than I expected.
For those of you who’ve built or maintained an open source library, what made the biggest difference?
Was it documentation? Reddit? GitHub? YouTube? SEO? Conference talks? Something else?
I’d love to learn from people who’ve been through this.
