A simple (but correct) library for validating email addresses. Supports mail addresses as defined in rfc5322 as well as the new Internationalized Mail Address standards (rfc653x). Based on https://github.com/jstedfast/EmailValidation
npm i is-mail-fine
bower i is-mail-fine
import isMailFine from 'is-mail-fine';
// global
isMailFine(
email, // the email address to check
allowInternational // true/false, will allow international addresses (e.g cyrillic or chinese),
allowTopLevelDomains // true/false, will allow top level domains
);A few tests can be found here: http://jsfiddle.net/coder13/arL3hq26/
