Archived: Unreliable

Note: If the domain is registered, but has no DNS server, domain-check will show it as available (and in this instance, there is now way to differenciate if it is available or not). domain-check uses DNS resolving to check whether a domain points to anywhere. Most commonly people have their domain automatically hooked up to their registrar's DNS servers. But in the case that it's registered but points to no where, it will show as available when it's actually taken...

Ultimately making this library unreliable.

domain-check

Check the availability of a domain or multiple through the command line tool or as a node module...

$ npm install -g domain-check

Usage

To use domain-check, you can either use the CLI tool, or use it in-script as a module. The CLI tool is good if you need to check a domain's status. The in-script module is good if you need to use it programmatically.

CLI

Usage
c [flags] <domain, domain, ...>

The CLI has a few flags:

• -s: Sort both taken and available into sections.
• -a: Only output available domains.
• -t: Only output taken domains.
• -n: No color.
• -i: Read from stdin stream,

Any argument that is not marked with a - is considered a domain and will be checked.

Also note that you can put multiple flags together in one group... e.g. c -isn

You can also pipe into domain-check if you have domains listed elsewhere, but you have to specify -i. Take this example, say we have a file full of domains that we want to check, we can use cat to read it, and then pipe it into domain-check:

$ cat domain_list.txt | c -is

Module

Simply require domain-check, and supply it with an array of domain names. Then use the callback argument to see the results:

const check = require('domain-check');

check(['example.com', 'google.com', 'foo.bar'], function(results){
  console.log(results);
});
// => { 'example.com':false, 'google.com':false, 'foo.bar': true }

In the results object, true represents that it's available, and false shows that it's taken.

You can use a for..in loop to get keys (domain names) if you need:

check(['example.com', 'google.com', 'foo.bar'], function(results){
  let available;
  for (for domain in results) {
    available = results[domain];
    console.log(domain + ': ' + available);
  };
});
// => example.com: false
// => google.com: false
// => foo.bar: true
