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

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:

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):

FUSION_SERVER_URL=http://192.168.1.50:5173 pnpm mobile:dev:android

Building for Production

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:

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.

Chat and Quick Chat mobile scroll/readability behavior

• Chat and Quick Chat must keep scrolling container-scoped (.chat-messages / .quick-chat-panel-messages) and must not switch to page-level scroll APIs (including scrollIntoView()) to avoid mobile Safari viewport drift.
• Both surfaces now pause live-tail autoscroll when the user scrolls away from bottom, show a temporary Latest jump control, and resume tail-follow only after jumping back.
• Mobile bubble widths are intentionally slightly wider for readability, but safe-area padding, full-screen Quick Chat bounds, and compact mobile tool-call summaries must remain intact.

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):

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
