Zod Validations

Some things to know with refine and superRefine

• Checkings in refine and superRefine will only run only if there are not invalid type error anymore on the base schema level.

  // example
  import { z } from 'zod'
   
  const formSchema = z
    .object({
      name: z.string(),
      identity_type: z.enum(['ID_CARD', 'PASSPORT']),
      is_married: z.boolean(),
      spouse_name: z.string(),
    })
    .refine((data) => data.is_married && data.spouse_name, {
      path: ['spouse_name'],
      message: 'Spouse Name must be filled',
    })

  The refine checking will only run if identity_type is one of ID_CARD or PASSPORT. It will not run if identity_type is still empty or undefined (invalid_type error).
