New Zod schema based on an existing one, with some fields having different validation rules?

Having some schema how I could re-use the schema and access some of its fields and change their validation to make up new schema.

const schema = z.object({
    details: z.object({
        name: z.string(),
        street: z.string(),
        coordinates: z.object({
            lat: z.string(),
            long: z.string(),
        }),
    }).partial().optional(),
    id: z.string().uuid(),
})

const schema = z.object({
    details: z.object({
        name: z.string(),
        street: z.string(),
        coordinates: z.object({
            lat: z.string(),
            long: z.string(),
        }),
    }).partial().optional(),
    id: z.string().uuid(),
})

Given this schema I would like the name field to be required/min length and have a new schema from this initial one with the rest fields being as is. In the inital schema only id would be required with the sub-schema id and name should be required rest optional

Solution:

what happens if you define a new schema with the fields you want to edit and then use merge? https://zod.dev/?id=merge

Well it seems to be working. Extend here seems better choice after playing with it as it need less z props through out. Thank you for suggestion ! ❤️
