Redirect POC – Demo

A small demo repo to test HTTP redirect behavior across platforms: a server redirects /file to an image URL; web, React Native, and Android clients load the image and can open the URL.

Useful for checking how each stack handles redirects (e.g. for file previews or auth flows).

What’s in here

Part	Tech	Purpose
server	Node + Express	Serves GET /file → 302 redirect to an image (e.g. picsum).
next-test	Next.js	Web client: shows image from server, “Open File” button.
react-native-test	Expo / React Native	Mobile client: same behavior.
android	Kotlin + Jetpack Compose	Native Android client: same behavior.

Quick start

1. Start the server (required for all clients):

   cd server
   npm install   # once
   node server.js

   Server runs at http://localhost:4000. You should see: Server is running on port 4000.

2. Run any client:

   • Web (Next.js):
     cd next-test && npm install && npm run dev
     Open http://localhost:3000.

   • React Native (Expo):
     cd react-native-test && npm install && npx expo start

     • iOS Simulator: keep LOCAL_IP = "localhost" in App.js.
     • Android emulator: use LOCAL_IP = "10.0.2.2".
     • Real device: set LOCAL_IP to your machine’s local IP (same Wi‑Fi).

   • Android (native):
     Open android/ in Android Studio, run on emulator.
     Emulator uses 10.0.2.2 to reach the host; for a real device you’d change the host in MainActivity.kt to your machine’s IP.
