Install

npm install validator-magic

Usage:

var validator = require('validator-magic');

var myobject = {
    username: 'Elao',
    email:    'contact@elao.com',
};

var rules = {
    username: {required: true},
    email:    {required: true, isEmail: true},
    website:  {required: true, isUrl: true}
};

validator.ObjectValidator(rules).validate(myobject)
         .then(function() { /** Validation succeed **/ })
         .catch(function(e) {
            /** Validation failed **/
         })

=> Nested objects validation

=> Global validators

=> Post validator

=> Customize field label and errors messages

=> Getting validation errors as a flat object

=> Available Asserts:

required: ...

isEmail: ...

=> Using the validation groups :

Exemple:

var rules = {
    username: {
        isRequired: {
            value: true,
            group: ['create']
        }
    },
    email: {
        isRequired: {
            value: true,
            group: ['create']
        },
        isEmail: true
    }
}

=> Using the custom validator :

Exemple with boolean validation:

    var rules = {
        username: {
            custom: function(fieldValue, ruleValue, data) { return isItValid ? true : false }
        }
    }

Exemple with promise validator:

    var rules = {
        username: {
            custom: function(fieldValue, ruleValue, data) { return new Promise(function(resolve, reject) { return isItValid ? resolve() : reject() }) }
        }
    }

=> Adding custom validator (to reuse validator) - or overwrite existing

var validator = require('validator-magic');

var newValidatorTypes = {
    myNewValidatorType: function(fieldValue, ruleValue, data) {
        return new Promise(function(resolve, reject) {
            if (ruleValue.)
        });
    }
}
