Environment

@mizdra/graphql-codegen-typescript-fabbrica version: 0.3.2 typescript version (optional): @graphql-codegen/cli version (optional): @graphql-codegen/typescript version (optional):

Summary

I would expect a type error to be reported when an unknown field is passed to defaultFields, but it is not.

type Book {
  title: String!
}

import { defineBookFactory } from '../__generated__/fabbrica';

const BookFactory = defineBookFactory({
  defaultFields: {
    title: 'Yuyushiki',
    // @ts-expect-error I expect a type error to be reported, but it is not.
    unknownField: 'hello',
  },
});

Additional comments

It may be necessary to assign a dedicated type parameter for each field.

It may be a good idea to provide a lint rule. https://github.com/johnsoncodehk/typescript-linter would be useful for it.
