Splits an url into sub-domain, domain and top-level-domain.
Since domains are handled differently across different countries and organizations, splitting an url into sub-domain, domain and top-level-domain is not a simple regexp. parse-domain uses a large list of known tlds (borrowed from http://publicsuffix.org) to recognize different parts of the domain.
var parseDomain = require("parse-domain");
expect(parseDomain("some.subdomain.example.co.uk")).to.eql({
subdomain: "some.subdomain",
domain: "example",
tld: "co.uk"
});
expect(parseDomain("https://user:[email protected]:8080/some/path?and&query#hash")).to.eql({
subdomain: "",
domain: "example",
tld: "co.uk"
});
expect(parseDomain("unknown.tld.kk")).to.equal(null);
expect(parseDomain("invalid url")).to.equal(null);
expect(parseDomain({})).to.equal(null);
Returns null if url has an unknown tld or if it's not a valid url.

tld: String,
domain: String,
subdomain: String
