Generate schemas for Query operations #472
Description
I need the schemas not just for graphql inputs but also for graphql queries to be able to validate preloaded data from the database for a page. I can't just use withObjectType because it potentially contains more fields than the graphql query.
Example
GraphQL type:
type Author {
email: String!
name: String!
password: String!
}My GraphQL query operation:
query Author {
author {
email
}
}The zod schema I get:
export function AuthorSchema(): z.ZodObject<Properties<Author>> {
return z.object({
email: z.string(),
name: z.string(), // this field I don't want
password: z.string() // this field I don't want
})
}Instead I need a schema like this:
export function AuthorQuerySchema(): z.ZodObject<Properties<AuthorQuery>> {
return z.object({
email: z.string()
})
}

Curious if there's any plan to add this feature? Would be super helpful to have schema parsers for queries when the data is cached somewhere and needs to be parsed back.

@charlescrain No I don't have plan for query. I accept PR because there are too many patterns, but most recently I am not going to work on them

Fixed in #1423. Zod and Zod v4 now have withOperationType, which generates schemas from operation selection sets instead of the full object type.
