Default scalar type for client generation from schema with many scalars

[linjmeyer]

When using client code generation from a schema with a lot of scalers the typeMapping option gets very cumbersome. Here is an example mapping a large amount of Gitlab GraphQL Id fields. Gitlab resources all have a scaler Id of a custom type. For example User.Id is type UserId which is really just a string that looks something like gib://Users/{number}. Mapping that to a string is fine for my use case.

To get code generation working on all these, I need:

typeMapping = [

Am I missing something, is there a more automatic way of doing this?

Unfortunately this is the only way to handle custom scalars since the codegen plugin does not have a way of knowing what to map it to otherwise.
