• Promisify mongoose functions

Declaration example

Schema :

'use strict';
 
const Joi = require('joi');
 
module.exports = Joi.object({
    firstName       : Joi.string().required(),
    lastName        : Joi.string().required(),
    age             : Joi.number().integer(),
    emailAddress    : Joi.string().email().required(),
    login           : Joi.string().required(),
    password        : Joi.string().required()
});

Model :

'use strict';
 
const jsonToMongoose    = require('json-mongoose');
const async             = require('async');
const bcrypt            = require('bcrypt');
const mongoose          = require('mongoose');
 
module.exports = jsonToMongoose({
    mongoose    : mongoose,
    collection  : 'user',
    schema      : require('../schemas/user'),
    autoinc     : {
        field : '_id'
    },
    pre         : {
        save : (doc, next) => {
            async.parallel({
                password : done => {
                    bcrypt.hash(doc.password, 10, (err, hash) => {
                        if (err) {
                            return next(err);
                        }
                        doc.password = hash;
                        done();
                    });
                }
            }, next);
        }

    schemaUpdate : (schema) => {
        schema.login.unique         = true;
        schema.emailAddress.unique  = true;
 
        return schema;
    },
    transform : (doc, ret, options) => {
        delete ret.password;
