##Usage in NodeJS

const getDomainUrl = require('get-domain-url');

This function expect two parameters

getDomainUrl(possibleDomain [,baseProtocol]);
possibleDomain - string, not required (always return null if missed);
baseProtocol - string, not required, default = 'http';

baseProtocol can accept all notations of protocol: 'http', 'http:', 'http://', but it doesn't check any whitelist of possible network protocols

Function return string with correct domain url if it possible, and null - if not

!!!Warning! It doesn't check if TLD domain zone is correct

getDomain('domain.incorrectDomainZone'); // 'http:/domain.incorrectDomainZone';

getDomainUrl('my-domain.com'); // 'http://domain.com'
getDomainUrl('https://domain.com'); // 'https://domain.com'
getDomainUrl('domain.com', 'https'); // 'https://domain.com'
getDomainUrl('domain.com/pa/th/?qu=ery#hash); // 'https://domain.com'

//should transform domain url to punycode format
getDomainUrl('тест.рф); // 'http://xn--e1aybc.xn--p1ai'

//should return null if input string can't quack like a domain
getDomainUrl('simplestring'); //null
getDomainUrl(); //null

// ...and if hostname is invalid
getDomainUrl('-domain.com') //null
getDomainUrl('domain-.com') //null
getDomainUrl('dom_in.com') //null
getDomainUrl('.dom-in.com') //null
