Hi! Im doing Clean Architecture pattern in my app. Let’s say I have a

Product

item. Now, that

Product

must contain

category

and

subcategory

. Currently, the API only returns the

guid

of the category and subcategory. Now the question is. Should the mapping of getting the

category

and

subcategory

from the API and putting them inside the

Product

class be inside the

data

module? OR I can put it inside my

GetProductUseCase

? If I choose the latter. So my usecase would look something like this:

getProducts()
    .zip(repo.getCategory(), repo.getSubCategory())
    .flatMap { 
        product.category = category
        product.subcategory = subcategory
     }

What’s the best practice for this?

Use cases should deal only with domain entities. The fact that the API returns

guids

is an implementation detail of the API and should be dealt by the

ProductRepository

implementation that deals with it. If in the future the API changes and starts returning nested elements your use case should remain the same and only de repository should change

Makes sense. Thanks for the input @Eric Martori! 💯
