mongoose-error-handler

Simplifies the errors from mongoose's scheme validation with internacionalization (i18nex) support

Validation Error

Before

    message: "domain validation failed",
    name: "ValidationError",
    errors: {
      myField: {
        properties: {
          type: "required",
          message: "ERROR MESSAGE",
          path: "myField",
          value: ""
        },
        message: "ERROR MESSAGE",
        name: "ValidatorError",
        kind: "required",
        path: "myField",
        value: ""
      }

After

    errors: { 
        myField: "domain.domainRequired"
    }

Mongo Error

Before

    {
    driver: true,
    name: "MongoError",
    index: 0,
    code: 11000,
        errmsg: "E11000 duplicate key error collection: reportsService.service_5d272c4bf7b1cd009d593403 index: origin_id_1 dup key: { : \"TestOrigin\" }"
    }

After

    errors: { 
        MongoError: "E11000 duplicate key error collection: reportsService.service_5d272c4bf7b1cd009d593403 index: origin_id_1 dup key: { : \"TestOrigin\" }"
    }

Exemple 1 ( Without internacionalization )

 
// LOAD THE RESOURCES
mongoose = require('mongoose');
config = require('../config/general');
mongoose.connect(config.database);
 
// LOAD MODULE
mongooseErrorHandler = require('mongoose-error-handler');
 
// LOAD MODEL
var myModel = require('../models/myModel');
 
 
    var newModel = new myModel({
 
        myField: 'foo',
 
    });
 
var error = newModel.validateSync();
 
console.log(mongooseErrorHandler.set(error));
 

Exemple 2 - A Route in Node.js Express( With i18next internacionalization )

 
// LOAD THE RESOURCES
router = require('express').Router();
mongoose = require('mongoose');
config = require('../config/general');
mongoose.connect(config.database);
 
// LOAD MODULE
mongooseErrorHandler = require('mongoose-error-handler');
 
// LOAD MODEL
var myModel = require('../models/myModel');
 
router.post('/myroute', function(req, res, next) {
 
    var newModel = new myModel({
 
      myField: 'foo',
 
    });
 
    // save
    newModel.save(function(err) {
        
            if(err)
 
                // An Example of error handling
                res.status(400).json({success: false, msg: mongooseErrorHandler.set(error, req.t)});
                
            else
       			res.status(200).json({success: true, msg: req.t('myInternacionalizedString')});       
 
    });
 
});
 
module.exports = router;
 
 

Exemple 3 - A Route in Node.js Express( With i18next internacionalization and String Replacement )

 
// LOAD THE RESOURCES
router = require('express').Router();
mongoose = require('mongoose');
config = require('../config/general');
mongoose.connect(config.database);
 
// LOAD MODULE
mongooseErrorHandler = require('mongoose-error-handler');
 
// LOAD MODEL
var myModel = require('../models/myModel');
 
router.post('/myroute', function(req, res, next) {
 
    var newModel = new myModel({
 
      myField: 'foo',
 
    });
 
    // save
    newModel.save(function(err) {
        
            if(err)
 
                // An Example of error handling
                res.status(400).json({
                    success: false, 
                    msg: mongooseErrorHandler.set(error, req.t, {variable: 'stringForReplacement'})
                    });
                
            else
       			res.status(200).json({success: true, msg: req.t('myInternacionalizedString')});       
 
    });
 
});
 
module.exports = router;
