# Domain Regex

[![Build Status](https://travis-ci.org/johnotander/domain-regex.svg?branch=master)](https://travis-ci.org/johnotander/domain-regex)

A regular expression for matching valid domain names. This regex seeks to support all

domains with TLDs listed on

[publicsuffix.org](https://publicsuffix.org/list/effective_tld_names.dat) including

[IDNs](http://en.wikipedia.org/wiki/Internationalized_domain_name).

In the near future this will be likely moved to .

## Installation

```

npm i --save domain-regex

```

## Usage

```javascript

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](https://github.com/bestiejs/punycode.js).

```javascript

var domainRegex = require('domain-regex');

var punyCode = require('punycode');

domainRegex().test(punycode.toASCII('岡山.jp')) // => true

```
