🦄 Fx

Fx is a dependency injection system for Go.

Benefits

Eliminate globals: Fx helps you remove global state from your application. No more init() or global variables. Use Fx-managed singletons.
Code reuse: Fx lets teams within your organization build loosely-coupled and well-integrated shareable components.
Battle tested: Fx is the backbone of nearly all Go services at Uber.
