Mongoose - validate email syntax

mongoose email validation
mongoose validate unique email
email regex
mongoose enum
mongoose validation error
mongoose schema
npm validator
mongoose async validation

I have a mongoose schema for users (UserSchema) and I'd like to validate whether the email has the right syntax. The validation that I currently use is the following:

UserSchema.path('email').validate(function (email) {
  return email.length
}, 'The e-mail field cannot be empty.')

However, this only checks if the field is empty or not, and not for the syntax.

Does something already exist that I could re-use or would I have to come up with my own method and call that inside the validate function?

You can use a regex. Take a look at this question: Validate email address in JavaScript?

I've used this in the past.

UserSchema.path('email').validate(function (email) {
   var emailRegex = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
   return emailRegex.test(email.text); // Assuming email has a text attribute
}, 'The e-mail field cannot be empty.')

you could also use the match or the validate property for validation in the schema

example

var validateEmail = function(email) {
    var re = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
    return re.test(email)
};

var EmailSchema = new Schema({
    email: {
        type: String,
        trim: true,
        lowercase: true,
        unique: true,
        required: 'Email address is required',
        validate: [validateEmail, 'Please fill a valid email address'],
        match: [/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/, 'Please fill a valid email address']
    }
});

I use validator for my input sanitation, and it can be used in a pretty cool way.

Install it, and then use it like so:

import { isEmail } from 'validator';
// ... 

const EmailSchema = new Schema({
    email: { 
        //... other setup
        validate: [ isEmail, 'invalid email' ]
    }
});

works a treat, and reads nicely.

The validator dosn't play well with mongoose to get rid of the warning set isAsync to false

const validator = require('validator');

Mongoose v5.9.27: Validation, Some thoughts on validating data according to a Mongoose Schema. var UserSchema = new Schema({ email: { type: String, validate:� UserSchema.path('email').validate(function (email) { return email.length }, 'The e-mail field cannot be empty.') cependant, cela ne vérifie que si le champ est vide ou non, et pas pour la syntaxe. Existe-t-il déjà quelque chose que je pourrais réutiliser ou devrais-je inventer ma propre méthode et l'appeler à l'intérieur de la fonction

For some reason validate: [ isEmail, 'Invalid email.'] doesn't play well with validate() tests.

const user = new User({ email: 'invalid' });
try {
  const isValid = await user.validate();
} catch(error) {
  expect(error.errors.email).to.exist; // ... it never gets to that point.
}

But mongoose 4.x (it might work for older versions too) has other alternative options which work hand in hand with Unit tests.

Single validator:

email: {
  type: String,
  validate: {
    validator: function(value) {
      return value === 'correct@example.com';
    },
    message: 'Invalid email.',
  },
},

Multiple validators:

email: {
  type: String,
  validate: [
    { validator: function(value) { return value === 'handsome@example.com'; }, msg: 'Email is not handsome.' },
    { validator: function(value) { return value === 'awesome@example.com'; }, msg: 'Email is not awesome.' },
  ],
},

How to validate email:

My recommendation: Leave that to experts who have invested hundreds of hours into building proper validation tools. (already answered in here as well)

npm install --save-dev validator

import { isEmail } from 'validator';
...
validate: { validator: isEmail , message: 'Invalid email.' }

Comments
  • Awesome! I didn't know about the test() method either.
  • You should define the regex outside of the function for better performance.
  • This regex fails to validate some valid emails, such as those include the plus sign on the lefthand side.
  • can't help but notice the end part, is that any word between 2-4 chars long? does this mean an email like info@company.london will not work? the regex is probably wrong.
  • @Val these TLDs didn't exist back in 2013. Take a look at this answer for an up-to-date regex
  • nice solution. but only problem is it's not passing eslint regex rule. could you please update?
  • What's difference between validate and match?
  • @Anatoly validate specifies a function to be called for validation (doesn't need to use regexes), match specifies a validation regex directly.
  • for ES5 :) , const validator = require('validator'); validate: [validator.isEmail, 'invalid email'],
  • const wasn't available in ES5 unfortunately.
  • smaller chuck with import isEmail from 'validator/lib/isEmail';
  • without isAsync: false , validation was not working in my case, i was using mongoose with promise. mongoose version 5.2.13
  • do NOT recommend such an approach. As you are defining User schema and you are using User.findOne before schema was declared.
