Joi Persian Validators

A set of persion validations built on top of Joi object validator. This idea came to my mind when I had to rewrite the same validator over and over again. Feel free to open an issue to ask for more validation rules.

Demo

⚓️ Installation

Install the package using yarn or npm

npm i joi joi-persian-validators

// or

yarn add joi joi-persian-validators

📜 How to use it

This library is a set of extenstions of top of Joi validator, thus you can use it with react-hook-forms or formik. Feel free to take a look at examples. Using this lib is fairly simple, first you need to import the lib;

import joi from 'joi';
import persianJoi from 'joi-persian-validators';

then you have to add persian extenstions to your joi instance.

// Add custom validators to a single joi instance
const pJoi = joi.extend(...persianJoi);

// Then create your custom schema
const schema = pJoi.object({
  mobile: pJoi.mobile(),
  id: pJoi.idNumber()
});

// commonjs
const Joi = require('joi').extend(...require('joi-persian-validators'));

// Then create your custom schema
const schema = Joi.object({
  mobile: Joi.mobile(),
  id: Joi.idNumber()
});

Example

To see how it works with react-hook-forms see this Example

import joi from 'joi';
import extensions from 'joi-persian-validators';

const phoneNumber = '09123334433';
// Also you can use persian characters, the value will be returned with english characters
const testId = '۴۳۱۱۰۲۰۴۶۵';

const pJoi = joi.extend(...extensions);

const schema = custom.object({
  phone: pJoi.phone(),
  id: pJoi.idNumber(),
});

const { value } = schema.validate({ phone: phoneNumber, id: testId });
// value = { phone: '09123334433', id: '4311020465' }

💬 Displaying custom messages

const schema = pJoi.object({

    'mobile.irancell': 'شماره ای که وارد کردید حتما باید ایرانسل باشد',

});

/*
  Valid Data
*/
const phoneNumber = '09332221122';
const id = '۴۳۱۱۰۲۰۴۶۵';

const { value } = schema.validate({ phone: phoneNumber, id });

// value = 
// { phone: '09332221122', id: '4311020465' }

/*
  Invalid Data
*/
const phoneNumber = '00332221122';
const id = '۴۳۱۱۰۲۰۴۶۵';

const { value, error } = schema.validate({ phone: phoneNumber, id });

// error =
/*
