Zod, Valibot and validator

TypeScript schemas

nusaindex/zod and nusaindex/valibot export the same factories. Zod (^4) and Valibot (^1) are optional peer dependencies: install the one you use.

Factory	Accepts	Output
`nik()`	A NIK	The input string, unchanged
`npwp()`	A 15-digit, 16-digit NPWP or NITKU	The input string, unchanged
`phone()`	A phone number	The input string, unchanged
`nip()`	A NIP	The input string, unchanged
`nisn()`	A NISN	The input string, unchanged
`plate()`	A vehicle plate	The input string, unchanged
`rupiah()`	Rupiah text such as `Rp 25.000,-`	A `number` in rupiah

Identifier schemas validate without transforming, so you decide whether to store the original or a normalized value (nik.format, phone.format). Every factory takes { message }. The error message never contains the input. Zod issues carry the NusaIndex error code in params.nusaindex.

Zod
Valibot

import { z } from "zod";
import * as id from "nusaindex/zod";

const Customer = z.object({
  nik: id.nik({ message: "NIK tidak valid" }),
  phone: id.phone(),
  deposit: id.rupiah(),
});

const result = Customer.safeParse(form);

import * as v from "valibot";
import * as id from "nusaindex/valibot";

const Customer = v.object({
  nik: id.nik({ message: "NIK tidak valid" }),
  phone: id.phone(),
  deposit: id.rupiah(),
});

const result = v.safeParse(Customer, form);

Go: go-playground/validator

NusaIndex does not depend on any validation library. Register the Valid functions you need:

validate := validator.New()
_ = validate.RegisterValidation("nik", func(fl validator.FieldLevel) bool {
  return nik.Valid(fl.Field().String())
})
_ = validate.RegisterValidation("phone_id", func(fl validator.FieldLevel) bool {
  return phone.Valid(fl.Field().String())
})

type Customer struct {
  NIK   string `validate:"required,nik"`
  Phone string `validate:"required,phone_id"`
}
