Simple validations with redux-form

import React from 'react'
import { FormattedMessage } from 'react-intl'
import { regFormat } from './helpers'

export var REG_EMAIL = /^[a-z0-9!#$%&\'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&\'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?$/i

// To be extracted by react-intl
let EMAIL_ERROR = (<FormattedMessage id="form.errors.email" defaultMessage="is not a valid email" />)

// Uses "format" internally which is already memoized
let email = function (options) {
  options = Object.assign({}, options)
  return regFormat(options, REG_EMAIL, EMAIL_ERROR)
}

export default email
