Build a scalable Go dependency injection container by creating a root injector with do.New(), registering services using do.Provide or do.ProvideValue, and resolving them at startup via do.MustInvoke to wire services with type safety.

Manage per-service lifecycles in a Go DI container by defining explicit providers with lazy, eager, transient, or value scopes. This structured approach handles initialization timing and integrates graceful shutdown hooks for each service.

Override dependencies for isolated testing in Golang by cloning your DI container and applying explicit service overrides. This test-ready pattern allows swapping mock implementations without altering the root injector's production providers.

Yes, you can use scoped containers and named services for modular Go architecture. The DI container supports implicit and explicit aliasing, while do.Package encourages separating infrastructure, domain, and transport layers.

Handle graceful shutdown and health checks with dependency injection by integrating built-in hooks directly into your DI container. This structure manages per-service lifecycles and cleanly orchestrates shutdown procedures across wired services.
