# Run all tests npm test # Run tests with coverage npm run test:coverage # Run security tests npm run test:security # Run linting npm run lint

🐛 Troubleshooting

Common Issues

  1. Connection refused errors

    • Check ERPNext URL and credentials

    • Verify firewall rules

    • Check Redis connection

  2. Authentication failures

    • Verify API key/secret

    • Check token expiration

    • Review audit logs

  3. Performance issues

    • Monitor Redis cache hit rate

    • Check ERPNext server load

    • Review rate limiting settings

Debug Mode

Enable debug logging:

LOG_LEVEL=debug npm start

📈 Performance Optimization

  • Caching: Redis caching with 5-minute TTL

  • Connection Pooling: Reuse HTTP connections

  • Batch Operations: Support for bulk document operations

  • Compression: Gzip compression for API responses

  • CDN: Optional CloudFlare integration
