Dependency Lifecycle

The dependency lifecycle in Remy DI describes how services are registered, instantiated, and retrieved throughout your application’s execution.

Design Philosophy

Remy is designed to work seamlessly with your existing code without requiring any modifications to your types or constructors. Your raw types and constructors work as-is — no special interfaces to implement, no struct tags to add, and no wrapper types needed.

All dependency injection configuration happens only at registration time. This means:

✅ Your existing types and constructors remain unchanged
✅ No need to modify your business logic for dependency injection
✅ All injection setup is centralized in your registration code
✅ Easy to add or remove dependency injection without touching your core code

This approach keeps your codebase clean and maintainable, allowing you to adopt dependency injection incrementally without refactoring your entire application.
