Joi18nz

Internacionlization(i18n) error messages for Joi

Getting Started

For using Joi18nz is very simple:

'use strict';
const Joi = require('joi18nz')(require('joi'), __dirname + '/locale');

You must send to joi18nz an intance of Joi and the directory of the translation files.

After, initializing the module, you have the instance of Joi, and you can use that like you use Joi.

You can translate your messages, simple adding an extra option in your validate function.

let schema = {
  name: Joi.string().required()
};
 
let value = {};
 
Joi.validate(value, schema, {i18n: 'pt_BR'}, function (err, data) {
  console.log(err, data);
});
// output
/*
{ [ValidationError: falha em "name", pois ["name" é obrigatório]]
  isJoi: true,
  name: 'ValidationError',
  details: 
   [ { message: '"name" é obrigatório',
       path: 'name',
       type: 'any.required',
       context: [Object] } ],
  _object: {},
  annotate: [Function] } {}
*/

For more information about how translate the tokens, you can see the pt_BR translation inside the i18n directory in this project.

NOTE: If you specify an invalid path to your folders we just use the default english version for the errors or the translations default in the i18n directory in this project.

After all, you just have a Joi instance, you can use that like you use Joi in your project, no incompatibilities with an existing implementation.
