# Nexus POS — Mobile App Build Guide

## Prerequisites
- Node.js 18+
- Android Studio (for Android)
- Xcode 15+ (for iOS, macOS only)

## Architecture

The Capacitor app loads the POS from the remote server at
`https://pos.nexusautoparts.com.mx/pos`. This means:
- The app requires internet on first load.
- The PWA service worker handles offline caching after that.
- No HTML/JS/CSS is bundled into the native binary.

## Android Build

```bash
cd /home/Autopartes/pos
npx cap sync android
npx cap open android
# In Android Studio: Build > Generate Signed APK
```

## iOS Build

```bash
cd /home/Autopartes/pos
npx cap sync ios
npx cap open ios
# In Xcode: Product > Archive
```

## Development

```bash
npx cap run android --livereload --external
npx cap run ios --livereload --external
```

## App Icons & Splash Screens

Place source images in `mobile/resources/`:
- `icon.png` — 1024x1024 app icon
- `splash.png` — 2732x2732 splash screen

Then generate platform assets:
```bash
npx @capacitor/assets generate
```
