Architecture

Backend: Node.js + Express
Frontend: Pure HTML/CSS/JS (no frameworks)
Data Source: openclaw sessions list --json + openclaw cron list --json
Caching: In-memory cache with 30-second TTL
- Pre-warmed on server startup
- Async background refresh when expired
- Stale-while-revalidate pattern for optimal UX
Refresh: Client-side polling (60s interval)

Performance

Without cache: - API response time: ~15 seconds (blocking) - Problem: Each request blocks Node.js event loop

With cache: - Cache hit: <100ms (~365x faster) - Cache miss: ~15s (first request only) - Stale cache: <100ms while refreshing in background - Cache TTL: 30 seconds

The caching system ensures: - Lightning-fast responses for most requests - No blocking of concurrent requests - Graceful degradation when cache expires
