How to extend or replace a rule?

[chepe263]

In spanish, the string for mixed.notType is a little odd

[field] debe ser un "number" Tipo, Pero el valor final fue: NaN (Eche el valor "".)

To replace just one rule, I imported the es locale, de-estructured it, modified it and exported it again

// custom-es-locale.js
import * as yupLocales from 'yup-locales';
const {array, boolean, date, mixed, number, object, string} = yupLocales.es

const new_mixed = Object.assign({}, mixed, {
  notType: ({path}) => {
    return `${path} no es válido`
  }
})

export default {
  array, boolean, date, mixed: new_mixed, number, object, string
}

Then proceed as the example

// your-main.js
import { custom_es } from './custom-es-locale.js';
import { setLocale } from 'yup';
setLocale( custom_es );

Is there a better way?

I don't see any other way right now...

Maybe shortening custom-es-locale.js:

// custom-es-locale.js
import { es } from 'yup-locales';
es.mixed.notType = ({path}) => `${path} no es válido`
export default es
