- AudioInputSection now subscribes to AudioManager.onResumed and bumps an audioCtxGen state on each 'running' transition. Mic-level meter and resolved-default hint effects depend on it, so opening Settings before joining voice and then joining voice activates the meter without needing to remount the panel. Footer copy updated to match the new behavior. - SectionShell and DropdownItem extracted to settingsPanels/_shared/SettingsPickerPrimitives.tsx so Task 6 (AudioOutputSection) can import them instead of triplicating the markup. The _shared/ folder keeps these settings-internal primitives out of the broader ui/ namespace. - Deliberate scope choice: VideoSection.tsx still has its own DropdownItem copy. Unifying all three is left to a follow-up; touching VideoSection here would expand scope beyond the audio-device-ux branch.

Quick Start with Docker
# Clone the repository
git clone https://github.com/your-username/backspace.git
cd backspace
# Create environment file
cp .env.example .env
# Generate a JWT secret
echo "JWT_SECRET=$(openssl rand -hex 32)" >> .env
# Start Backspace
docker compose up -d
Open http://localhost:3000 in your browser. A default server "Backspace" is created automatically.
Default admin account: admin / admin123 (change this after first login).
Development Setup
Prerequisites
- Node.js 20+
- pnpm 8+
Install
pnpm install
Configure
cp .env.example .env
# Edit .env with your settings (generate a JWT_SECRET)
Run
# Start both server and web dev server
pnpm dev
# Or start individually
pnpm dev:server # API server on :3005
pnpm dev:web # Vite dev server on :5173
Build
pnpm build
This builds the shared types, server, and web frontend. The server serves the built frontend in production mode.

Voice & Video
Voice and video requires a LiveKit server. Set these in your .env:
LIVEKIT_URL=wss://your-livekit-server
LIVEKIT_API_KEY=your-api-key
LIVEKIT_API_SECRET=your-api-secret
Without LiveKit configured, text chat works fully but voice/video channels will not connect.
API
The server exposes a REST API and WebSocket endpoint:
- REST API:
http://localhost:3000/api/* - WebSocket:
ws://localhost:3000/ws - Health check:
GET /api/health
See CLAUDE.md for the full API reference.
Desktop App
The Electron desktop app wraps the web UI and adds system tray, notifications, and native window controls.
cd packages/desktop
pnpm build:ts # Compile TypeScript
pnpm dev # Run in development
pnpm build # Package for distribution
