mongoose-error-handler

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

Validation Error

Before

``json
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

`json
errors: {
myField: "domain.domainRequired"
}
`

Mongo Error

`json
{
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

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

Exemple 1 ( Without internacionalization )

`javascript

// 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 )

`javascript

// 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 )

`javascript

// 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;
