Adds a native desktop application shell in electron/ that wraps the
existing Docker-based NOMAD stack in an Electron BrowserWindow.
Architecture:
- Single instance lock prevents multiple app copies from running
- Main process manages the full Docker Compose lifecycle (up/stop)
- Health-check polling (GET /api/health) with 3-minute timeout before
loading the NOMAD web UI in the BrowserWindow
- System tray stays alive when the window is closed, with menu items
for Show/Hide, Open in Browser, Restart, Stop, and Quit
- Retry button on the loading screen re-runs the launch sequence
without needing to restart the app
Files:
electron/package.json - Electron 34 + electron-builder config
Targets: AppImage/deb (Linux), DMG (Mac),
NSIS (Windows); supports x64 + arm64
electron/tsconfig.json - CommonJS/ES2020 TypeScript for main process
electron/src/main.ts - Main process: window, tray, Docker helpers,
startup state machine, IPC handlers
electron/src/preload.ts - contextBridge: exposes onStatus / retryLaunch
to loading screen without full nodeIntegration
electron/src/loading.html - Branded startup screen with animated progress
bar, status messages, and error retry button
electron/assets/README.md - Icon file guide (512px PNG, tray 32px PNG,
ICNS for Mac, ICO for Windows)
Root scripts added:
npm run electron:install - install electron deps
npm run electron:build - compile TypeScript
npm run electron:dev - build + launch in dev mode
npm run electron📦* - package for linux/mac/win
