Note: Performance results are based on files containing actual dates. Files without dates are processed much faster but extract 0 dates.
Real-World Performance: Tested with actual data up to 10MB (practical limit: 1MB warning, 5MB error threshold)
Performance Monitoring: Built-in real-time tracking with configurable thresholds
Full Metrics: docs/PERFORMANCE.md • Test Environment: macOS, Bun 1.2.22, Node 22.x
For detailed information, see Performance Monitoring.
🔧 Troubleshooting
Not detecting dates?
Ensure file is saved with supported extension (.json, .yaml, .csv, .xml, .log, .html, .js, .ts)
Large files slow?
Files over 5MB may take longer. Consider splitting into smaller chunks
Need help?
Check Issues or enable logging: dates-le.telemetryEnabled: true
