Dependency injection in Go with Uber-go/fx

Agree. I really can only imagine this being useful for an organization that publishes dozens of different libraries that a "product team" needs to use such as logging, database access, secret managers, etc. At that point, speaking the common language of a DI framework might be easier.

For example, rather than have to read the GoDoc for every single constructor i'm supposed to use, I can just see how to use my DI framework to set up this client library and move on with my life.

That being said, DI always strikes me as a layer of abstraction that I don't need in my day to day. But I don't work somewhere at Google/Uber scale so YMMV.

There's nothing special about DI frameworks there. If a client library has some sane defaults preferred by the devs, then call a constructor that sets the defaults for you. You don't need DI for that.

IME at tech megacorps, DI just obfuscates and distracts, shifting the focus onto understanding the accidental complexity it introduces instead of dealing with the intrinsic complexity of the dependency relationships.
