General Purpose Struct to Reduce Dependency injection In Golang

General Purpose Struct to Reduce Dependency injection In Golang

Dependency injection but if you need more, you would have a big struct and messy code to work with. You might have other services do the same thing but for different repository classes. General purpose struct to reduce dependency injection in Golang.

Assume that you have a service class that depends on two database repository classes. This will require you to store both of them in the service struct. This is ok for small amount of dependencies but if you need more, you would have a big struct and messy code to work with. You might have other services do the same thing but for different repository classes. Finally you have a lot of duplicates all over the place. The solution to this problem is simple. We are going to create a main repository struct which will store all the other/sub repository interfaces in it. We than just use the main repository where we need. This will allow us to access all the embedded repositories form it. A bit like a strategy pattern.
