💡 UUID Best Practices
- Use version 4 UUIDs when you need random identifiers
- For ordered IDs, consider version 1 UUIDs or ULIDs
- Store UUIDs as binary(16) in databases for better performance
- Consider UUID v7 (time-sorted) for database indexes
- Validate UUIDs with regex
/^[0-9a-f]{8}-[0-9a-f]{4}-4[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/i
