Mongoose - validate email syntax

Question

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?

Answer 1

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']     } }); 

Answer 2

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.
