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
