# Mobile Development Guide
Fusion mobile builds package the dashboard web client into Capacitor shells via `packages/mobile/`.
## Prerequisites
- **Node.js** 22+
- **pnpm** 10+
- **Xcode** (iOS builds)
- **Android Studio** (Android SDK + emulator tooling)
- **Java JDK** 17+ (Android Gradle builds)
## Quick Start
```bash
pnpm install
pnpm mobile:build
pnpm mobile:ios # open iOS project in Xcode
# or
pnpm mobile:android # open Android project in Android Studio
```
## Development with Live Reload
Use the live-reload helpers in `packages/mobile/scripts/live-reload.ts`:
```bash
pnpm mobile:dev:ios
pnpm mobile:dev:android
```
These commands automatically set:
- `FUSION_LIVE_RELOAD=true`
- `FUSION_SERVER_URL=http://localhost:5173` (default)
To target a different dev server URL, set `FUSION_SERVER_URL` before running (or pass `--server-url` directly to the script):
```bash
FUSION_SERVER_URL=http://192.168.1.50:5173 pnpm mobile:dev:android
```
## Building for Production
```bash
pnpm mobile:build
```
This runs:
1. `pnpm --filter @fusion/dashboard build`
2. `pnpm --filter @fusion/mobile cap sync`
After sync, open native projects for release signing/distribution:
```bash
pnpm mobile:ios
pnpm mobile:android
```
## PWA Installation
The dashboard includes a PWA manifest (`packages/dashboard/app/public/manifest.json`) and service worker (`packages/dashboard/app/public/sw.js`).
### Standalone iOS home-indicator spacing
- Installed standalone mode sets `--standalone-bottom-gap` via `@media (display-mode: standalone) { :root { ... } }`.
- Bottom spacing must stay scoped to layout/component rules (for example mobile content padding and footer/nav offsets), not global `#root` padding.
- Keep standalone spacing additive with existing safe-area handling (`env(safe-area-inset-bottom, 0px)`).
Install from browser:
- **Chrome**: three-dot menu → **Install app**
- **Safari (iOS)**: **Share****Add to Home Screen**
> Service workers require **HTTPS** (or `localhost`). PWA install/offline behavior will not work on plain HTTP origins.
## Mobile UX Behavior
### Native shell onboarding and connection profiles
- First launch in the mobile shell enters a shell-level remote connection onboarding flow before dashboard model onboarding.
- Connection setup supports QR scan and manual URL entry, with optional auth token.
- Saved remote profiles are persisted in shell-local mobile storage and managed through `window.fusionShell` connection APIs.
- Shell connection persistence is intentionally separate from Fusion project/global settings.
### Planning Mode
Planning Mode opens directly into the composer pane on mobile when no planning sessions exist, avoiding an empty-sidebar dead end. On desktop/tablet the split view is unaffected. Once sessions are saved, mobile shows the session list as usual and the user can navigate between list and detail panes.
## CI/CD Pipeline
Mobile CI is defined in `.github/workflows/mobile.yml`.
- Trigger manually via **GitHub Actions → Mobile Builds → Run workflow**
- Also runs on push to `main` when files under `packages/mobile/**` or `packages/dashboard/**` change
- Jobs:
- `build-web` (build dashboard and upload `dist/client`)
- `build-ios` (sync/build iOS when `packages/mobile/ios/` exists)
- `build-android` (sync/build Android when `packages/mobile/android/` exists)
Artifacts are retained for 30 days.
## Replacing PWA Icons
Current icons are placeholders:
- `packages/dashboard/app/public/icons/icon-192.png`
- `packages/dashboard/app/public/icons/icon-512.png`
Generate production icons from `logo.svg` (example with sharp-cli):
```bash
npx sharp-cli -i packages/dashboard/app/public/logo.svg -o packages/dashboard/app/public/icons/icon-192.png resize 192 192
npx sharp-cli -i packages/dashboard/app/public/logo.svg -o packages/dashboard/app/public/icons/icon-512.png resize 512 512
```
You can also use ImageMagick if preferred.
## Troubleshooting
### `cap sync` fails
- Confirm dependencies are installed: `pnpm install`
- Ensure platform projects have been added (`packages/mobile/ios` / `packages/mobile/android`)
- Re-run: `pnpm mobile:sync`
### iOS build fails
- Verify Xcode version/toolchain compatibility
- Open `packages/mobile/ios/App/App.xcworkspace` in Xcode and resolve signing settings
### Android build fails
- Verify Java 17+ (`java -version`)
- Confirm Android SDK and Gradle tooling are installed via Android Studio
### PWA does not install
- Verify HTTPS (or localhost)
- Confirm `manifest.json` and `sw.js` are served from the built app
- Clear old service worker/cache and reload
