Sonamu is designed with developer experience as the top priority.

​
HMR (Hot Module Replacement)

When you modify code, it’s instantly reflected without server restart. Whether you modify Entity, Model, or API, 2 seconds is all you need. 
# Traditional approach: Modify Entity β†’ Restart server β†’ Wait 30 seconds
# Sonamu approach: Modify Entity β†’ Save β†’ Reflected in 2 seconds βœ…

# Console output example
πŸ”„ Invalidated:
- src/application/user/user.model.ts (with 8 APIs)

βœ… All files are synced!
If you make 50 modifications a day? Traditional approach wastes 25 minutes, Sonamu takes only 1.7 minutes.
