Adds an admin-driven sweep on top of the existing 24h auto-expire so
operators can see and reap abandoned `.tus/` sessions without waiting.
- storageJanitor: extract `walkTusDir(predicate)` helper, add
`getStaleTusInfo` + `cleanupStaleTusSessions(thresholdMs, dryRun)`;
refactor `cleanupTusStragglers` to delegate while preserving its
janitor-tick `{ removed }` contract.
- StorageStats gains `staleTusSessions` + `staleTusSize` (fixed 1h
display threshold).
- New `POST /api/admin/storage/cleanup-tus` route with
`maxAgeHours` validation (positive finite number, default 1) and
`dryRun` support; admin-gated.
- StoragePanel: 6th overview card "Stale Uploads" + new cleanup
subsection mirroring the media-cleanup pattern (preview-then-clean
with shared result panel styling).
- Tests: 8 new janitor tests covering empty dir, threshold filtering,
dry-run vs live, oldest-mtime tracking, subdir skipping, and the
override path on the existing straggler sweep. New
`routes/admin.test.ts` covers auth/admin gates, validation (zero,
negative, NaN), default `maxAgeHours`, dry-run vs live unlink.
- Docs: `uploads.md` §Janitor expanded to the full lifecycle (cancel
DELETE, discard DELETE, auto-expire, straggler sweep, admin route);
`admin.md` Storage Management updated with the new endpoint and
StorageStats fields.

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
