Domain Regex
A regular expression for matching valid domain names. This regex seeks to support all domains with TLDs listed on publicsuffix.org including IDNs.
In the near future this will be likely moved to https://github.com/regexps.
Installation
npm i --save domain-regex
Usage
var domain = require('domain-regex');
domain().test('example.aerodrome.aero') // => true
domain().test('a.sub.domain.org') // => true
domain().test('invalid_domain') // => false
IDN Support
This regex requires any Unicode character to be converted to its ASCII equivalent. This can be done with a library like punycode.js.
var domainRegex = require('domain-regex');
var punyCode = require('punycode');
domainRegex().test(punycode.toASCII('岡山.jp')) // => true
