Dependency injection and graceful shutdown in a Go application are managed using uber-go/fx, which provides a reflection-based DI container and lifecycle hooks for seamless component integration and state management.

The best way to structure modular Go services is using uber-go/fx Module composition, which enables modular design and maintainable codebases by organizing dependencies and lifecycle hooks into cohesive, reusable application blocks.

Yes, you can use uber-go/fx for long-running Go workers, HTTP servers, and daemons where managing boot order, modular composition, and graceful shutdown are crucial for application stability.

Setting up uber-go/fx requires the go.uber.org/fx and go.uber.org/dig libraries to automate the wiring and lifecycle management of your Go application's dependency injection container.

Lifecycle management in Golang with uber-go/fx works by providing lifecycle hooks that facilitate graceful shutdown and state management, ensuring long-running services start and stop in the correct boot order.

You should avoid using a reflection-based DI container like uber-go/fx for simple, short-lived Go scripts where the overhead of modular composition, lifecycle management, and dependency wiring provides no structural benefit.
