Dependency injection in a modular Go application is set up by creating a root container with do.New(), registering services using do.Provide, and retrieving them with do.Invoke. This enables type-safe wiring and predictable initialization at the composition root.

The best way to manage service lifecycles in Go DI is by using providers, lazy, eager, and transient initialization options. This allows flexible control over when services are instantiated and how long they persist within application scopes.

Yes, you can use scopes to organize dependencies across large Go modules. Scopes help establish clear lifecycle boundaries and modularize service wiring, making complex application architectures easier to maintain and test.

Yes, this dependency injection approach supports graceful shutdown and health checks for production-grade applications. These features ensure your services terminate safely and allow monitoring of dependency availability during runtime.

Struct injection works by automatically populating struct fields with resolved dependencies from the container. This simplifies wiring by directly injecting required services into struct instances without manual retrieval calls.
