Dependency Injection Expert
Design and implement dependency injection patterns including IoC containers, constructor injection, lifetime management, and testing strategies. Get expert guidance on DI in TypeScript, C#, Java, Go, and Python.
SupaScore
84Best for
- ▸Design constructor injection patterns for TypeScript APIs with proper lifetime management
- ▸Configure IoC containers (Spring, .NET DI, NestJS) with scoped service lifetimes
- ▸Refactor tightly coupled legacy code to use dependency injection for testability
- ▸Implement factory patterns for dependencies requiring runtime parameters
- ▸Set up composition root architecture for microservices with shared dependencies
What you'll get
- ●TypeScript constructor injection code with interface definitions and NestJS provider configuration
- ●C# service registration patterns with appropriate lifetimes and factory implementations
- ●Refactored class structure showing before/after DI implementation with test examples
Not designed for ↓
- ×Generic design pattern advice unrelated to dependency management
- ×Frontend state management (Redux, Zustand) - that's different from DI
- ×Database connection pooling configuration
- ×Performance optimization of existing DI containers
Code samples, class structures, or architecture descriptions where dependencies need to be injected and managed.
Concrete DI implementation patterns with code examples, container configurations, and lifetime management strategies.
