Go: How to resolve dependency for structs passing between two packages as params?

Don’t know what’s the best practice to structure this so I don’t have cyclic dependency, I have a user package which exposes UserService which takes a store because it needs to access database, but it also has some structs

package user

type UserParams struct {
    Client             util.HTTPExecutor
    Store              store.Store
    ...
}

func NewUserService(params *UserServiceParams) *UserService {...}


type User struct {
	ID               int32        `db:"id" json:"id"`
	Name             string       `db:"name" json:"name"`
}

At the same time I have a store package which has an interface takes some user structs and save into the database.

package store

type Store interface {
  UpdateUser(ctx context.Context, u *user.User) error
}

Does it make more sense to

1. Move User struct into store package (latter might end up a lot of those structs for different product components)
2. Move User struct into a separate common package so both packages have access to it
3. Move User struct into a package userstruct under user package

Thank you!

First of all, this question is slightly subjective because it depends largely on your project and how your project lays out. That being said, here is what I would do if I were you.

Consider adding a types package. A types package would rarely be dependent on anything else, but everything would be dependent on the types package. Then both your store and services packages could import the types package without any concern for cyclical dependencies.

Arrows denote a dependency/import
