Improve performance when serving /api/state in mock mode by optimizing
alert handling and JSON serialization.
Changes:
- Add UpdateAlertSnapshots() to cache alerts without blocking
- Use lazy population of alert snapshots to avoid lock contention
- Switch to json.Marshal for better performance with large payloads
- Add debug logging to track /api/state performance
- Simplify GetState() logic in mock mode
Performance improvements:
- Eliminates alert manager lock during /api/state requests
- Reduces JSON encoding overhead for large mock datasets
- Ensures sub-second response times even with 7 nodes and 90+ guests
Testing:
- Mock mode returns state instantly without blocking
- Alert snapshots populate correctly on first request
- Debug logs confirm fast execution path
- Update screenshot tool to use MacBook Air resolution (2560x1600)
- Remove empty side borders from screenshots
- Use mock data for all screenshots for privacy
- Fix mobile alert buttons overflowing viewport
- Exempt localhost from API rate limiting for better dev experience
- Update documentation to showcase all features with screenshots
- Reorganize README visual tour into feature sections
- Add high-quality screenshots with 3x device scale factor for crisp text
- Implement mock alert history generator spanning 90 days
- Update documentation with detailed screenshot descriptions
- Add visual tour section to README with key screenshots
- Fix mock mode to properly separate from production data
- Clean up screenshot script to use actual mock data instead of DOM injection
- Enhance FAQ and webhooks docs with relevant screenshots
