What problem does it solve?

Dependency injection in Go projects can become boilerplate-prone and hard to test; this skill provides a structured approach using samber/do/v2 to compose services, manage lifecycles, and enable clean testing.

Core Features & Use Cases

• Type-safe DI container at the composition root with clear lifecycle management (lazy, eager, transient, value)
• Support for scoped containers, named services, and implicit/explicit aliasing
• Built-in testing patterns: container cloning and overrides for isolated tests
• Health checks and graceful shutdown hooks integrated with the DI container
• Encourages modular package organization via do.Package for infrastructure, domain, and transport layers

Quick Start

Create a root injector with do.New(), register services with do.Provide or do.ProvideValue, and resolve them with do.MustInvoke.
