zod validation in javaScript

December 21, 2023

export type ResetPassword = {
  password: string
  confirmPassword: string
}

export const resetPasswordSchema: ZodType<ResetPassword> = z.object({
  password: z.string().refine((value) => value !== '', {
    message: 'Password is required'
  }),
  confirmPassword: z.string().refine((value) => value !== '', {
    message: 'Password is required'
  }).refine((data) => data.password === data.confirmPassword, {
    message: "Passwords don't match",
    path: ["confirmPassword"], // path of error
  })
})

i’m trying to use zod validation to check if the confirm password matches the password and i got this error!

Property ‘password’ does not exist on type ‘string’.
Property ‘confirmPassword’ does not exist on type ‘string’.

in this line

  }).refine((data) => data.password === data.confirmPassword, {

>Solution :

You will need to put the refine method on the end of the schema to get access to all the properties like this:

export const resetPasswordSchema: ZodType<ResetPassword> = z.object({
  password: z.string().refine((value) => value !== '', {
    message: 'Password is required'
  }),
  confirmPassword: z.string().refine((value) => value !== '', {
    message: 'Password is required'
  })
})
.refine((data) => data.password === data.confirmPassword, {
    message: "Passwords don't match",
    path: ["confirmPassword"], // path of error
})
