PrismaSelect - better typescript support

[skworden]

I'd like a way to pass our own defaultOptions type for PrismaSelect defaultOptions.

The select function is any, and the object keys are generic string.

For reference, here's an example that is fully typed for nexus autogenerated types. Nexus autogenerated types are dynamic nested objects.

import { NexusGenFieldTypes } from "/my/nexus-types.generated";

// Can be the current default option
type AllowedNexusTypes = Partial<
  Omit<NexusGenFieldTypes, "Mutation" | "Query">
>;

type DefaultFields<T = AllowedNexusTypes> = Required<{
  [K in keyof T]:
    | Partial<{ [P in keyof Required<T>[K]]: boolean }>
    | ((select: Required<T>[K]) => Record<string, boolean>);
}>;


const defaultFields: TDefaultFields = {
  Category: { id: true }, // key and options are typed
  Page: (select) => ({ // key, options, and select are typed
    id: true,
    categoryId: !!select.category,
  }),
  Tag: { id: true },
}
