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
