Email address helpers Build Status

Regular expressions ensuring the given input is a valid address.

This module ensure that we use the same approach for validating a given email address across all our services. It was originally lifted from the debitoor-app source/util-folder into its own module.

Overview

Helper functions

Two helper functions, isValid and isMultipleValid, are exposed. isValid is basically a wrapper calling .single.test from the regex section on the input, and isMultipleValid splits a string on commas (,), and verify that every item is a valid email address.

Usage:

var email = require('email-address');
email.isValid('joe@example.com'); // true
email.isValid('foo bar'); // false
email.isMultipleValid('john.doe@example.com,jane.doe@example.com'); // true
email.isMultipleValid('john.doe@example.com,jane.doe@example..com'); // false

Regexes

The following regexes are exposed:

  • .single the string is a valid email address.
  • .multiple the string is a comma seperated list of valid email addresses. Whitespace are allowed between the email addresses.
  • .optional the string is a valid email address or an empty string.

Usage:

var email = require('email-address');
 
// input is a vaild email address
email.single.test('joe@example.com'); // true
 
// input is a comma seperated list of valid email addresses
email.multiple.test('joe@example.com, jane@example.com'); // true
 
// input is a valid email address, or an empty string
email.optional.test('jane@example.com'); // true
email.optional.test(''); // true
