Redux Form sync validation but get constant rules from server

I have read the documentation how to use sync validation.

const validate = values => {
  const errors = {}

  ....

  if (!values.age) {
    errors.age = 'Required'
  } else if (isNaN(Number(values.age))) {
    errors.age = 'Must be a number'
  } else if (Number(values.age) < 18) {
    errors.age = 'Sorry, you must be at least 18 years old'
  }
  return errors
}

My need is I want the number '18' is retrieved from server? I need to setup all constants of the validation on server, and read it on page load only then used in this validation section.

Any help would be appreicated. thank you

I don't know if I understand the question correctly.
why don't you initiate validate method on page load after you fetch all constants from server.

validateConstants.js

export const validateConstants = fetch()

validation.js

import { validateConstants } from 'validateConstants'
const validate = values => {
  const errors = {}

  ....

  if (!values.age) {
    errors.age = 'Required'
  } else if (isNaN(Number(values.age))) {
    errors.age = 'Must be a number'
  } else if (Number(values.age) < validateConstants.age) {
    errors.age = 'Sorry, you must be at least 18 years old'
  }
  return errors
}
