This is a very simple module that will enable you generate as many domains as you want without having to type all of the different domains.

USAGE

var dg = require('domain-genetator');

var tld, domainlist, domain;
tld = [ '.com','...write other tld here...'];
domain = 'example.com';

//now generate the domains

domainlist = dg.dg(domain, tld, function(err){
    if (err) throw err;
}

console.log(domainlist);

Enjoy...!!!
