Go applications often suffer from tangled wiring and hard-to-test dependencies. submodule-go provides a type-safe DI framework that registers factories and resolves dependencies lazily within scopes, improving testability and maintainability.
Create a scope, register dependencies with Make, and Resolve a type to obtain a ready-to-use instance.

Type-safe dependency injection in Go is achieved by registering factories and resolving dependencies lazily within isolated scopes. This approach ensures predictable lifecycles, deterministic behavior, and compile-time safety for struct field injection.
Mocking dependencies in Go tests is handled through dependency overrides and substitution within isolated scopes. You can inject mock services directly during resolution, ensuring testability without altering the production codebase's structural wiring.
Managing service lifecycles in Go applications is done using per-scope singletons and lazy initialization. By creating isolated scopes, you ensure deterministic behavior and prevent shared state leakage across distinct request boundaries.
Lazy wiring for dependency resolution in Go applications defers instantiation until a type is explicitly resolved. This minimizes unnecessary initialization overhead and ensures resources are only allocated when the specific dependency is required.
Explicit error propagation during struct field injection is fully supported during the dependency resolution process. Errors from factory functions are safely propagated back to the caller, ensuring predictable failure modes when resolving complex service graphs.
