Pre requisites

You must have a definition json like this:

{
  "fields": [
    {
      "name": "name",
      "type": "text",
      "min-length": 3
    },
    {
      "name": "password",
      "type": "number",
      "max-length": 4,
      "min-length": 4,
      "required": true
    },
    {
      "name": "description",
      "type": "text-area"
    },
    {
      "name": "quantity",
      "type": "select",
      "values": {
        "0": "value_3",
        "1": "value_6",
        "2": "value_9"
      }
    },
    {
      "name": "themeColor",
      "type": "color"
    },
    {
      "name": "birthDay",
      "type": "date"
    },
    {
      "name": "arrival",
      "type": "time"
    }
  ]
}

This definition must have all the fields and the validations.

And you must have the data to be validated:

{
  "password": "1232",
  "description": "A great fidelity card",
  "quantity": "0"
}

Usage

First, you need to configure the language (m-validate uses i18n-2) passing a config object and the language you want your response.

i18n-2 will create the language files as they are needed, but you can set all translations using this base file.

var MValidate = require('../m-validate');
// The object is a i18n-2 config object. The second parameter is the locale
var validator = new MValidate({
  locales: [
    'en-US',
    'pt-BR'
  ],
  directory: './locales',
  extension: '.json'
},
 'pt-BR');

var fs = require('fs');

// Get the definition json here
var definitionPath = 'form.json';
var definitionContent = fs.readFileSync(definitionPath, 'utf8');
var definition = JSON.parse(definitionContent);
var definitionFields = definition.fields;

// Assuming the data comes from a post
var content = req.body;

// Response variable will have the result
var response = validator.validate(content, mobletDefinitionFields);

The validation response will be an object with two items: a boolean and an object.

The boolean is called "error" and will be true if any of the validations did not pass.

The object is called "result" and will have all the validated fields as an object. If any validation failed, this object will have the translated validation type and the result, for instance:

{
  error: true,
  response: {
    name: {},
    password: {
      required: 'field_is_required',
      'max-length': 'must_be_more_than_chars: 4'
    },
    description: {},
    quantity: {},
    position: {},
    color: {},
    themeColor: {
      type: 'not_a_color'
    },
    birthDay: {},
    arrival: {},
    email: {},
    siteaddress: {
      type: 'not_an_url'
    },
    phone: {
      type: 'not_a_tel'
    },
    cell: {}
  }
}
