npm install --save tldtsUsage
Using the command-line interface:
$ npx tldts 'http://www.writethedocs.org/conf/eu/2017/'
{
"domain": "writethedocs.org",
"domainWithoutSuffix": "writethedocs",
"hostname": "www.writethedocs.org",
"isIcann": true,
"isIp": false,
"isPrivate": false,
"publicSuffix": "org",
"subdomain": "www"
}Or from the command-line in batch:
$ echo "http://www.writethedocs.org/\nhttps://example.com" | npx tldts
{
"domain": "writethedocs.org",
"domainWithoutSuffix": "writethedocs",
"hostname": "www.writethedocs.org",
"isIcann": true,
"isIp": false,
"isPrivate": false,
"publicSuffix": "org",
"subdomain": "www"
}
{
"domain": "example.com",
"domainWithoutSuffix": "example",
"hostname": "example.com",
"isIcann": true,
"isIp": false,
"isPrivate": false,
"publicSuffix": "com",
"subdomain": ""
}Programmatically:
const { parse } = require('tldts');
// Retrieving hostname related informations of a given URL
parse('http://www.writethedocs.org/conf/eu/2017/');
// { domain: 'writethedocs.org',
// domainWithoutSuffix: 'writethedocs',
// hostname: 'www.writethedocs.org',
// isIcann: true,
// isIp: false,
// isPrivate: false,
// publicSuffix: 'org',
// subdomain: 'www' }Modern ES6 modules import is also supported:
import { parse } from 'tldts';Alternatively, you can try it directly in your browser here: https://npm.runkit.com/tldts

Contributors
tldts is based upon the excellent tld.js library and would not exist without
the many contributors who worked on the project.
This project would not be possible without the amazing Mozilla's public suffix list either. Thank you for your hard work!
