submodule-go

What problem does it solve?

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.

Core Features & Use Cases

• Type-safe registration with Make, Resolve, Value, Group, and CreateScope to model service graphs.
• Lazy initialization and per-scope singletons to ensure deterministic behavior and easy testing.
• Testability via isolated scopes, mock overrides, and structural wiring (submodule.In, submodule.Self) with minimal boilerplate.
• Supports dependency overrides and substitution to mock services in tests without changing production code.

Quick Start

Create a scope, register dependencies with Make, and Resolve a type to obtain a ready-to-use instance.
