Go Web Service Refactoring with Uber FX

The source is a technical article explaining the process of refactoring a monolithic Go web service built using the Gin framework into a modular and maintainable application by integrating Uber FX. The author outlines how Uber FX facilitates dependency injection and lifecycle management, solving the problems of hardcoded logic and poor testability present in the original structure. Key steps detailed include replacing the original entry point with an FX composition using fx.Provide to declare dependencies and fx.Invoke to wire application behavior, implementing lifecycle hooks for graceful startup and shutdown, and establishing a config-driven design for flexible settings. Ultimately, the refactoring results in a more robust and testable architecture, supported by behavioral testing that validates real endpoint interactions. https://medium.com/@mobinshaterian/refactoring-a-go-web-service-with-uber-fx-from-monolith-to-modular-elegance-2789a9ac8ec5
