What are tldts-core's main functionalities?

Extract Root Domain

This feature allows you to extract the root domain from a given URL. In the example, the root domain 'example.co.uk' is extracted from the URL 'https://www.example.co.uk'.

const tldts = require('tldts-core');
const rootDomain = tldts.getDomain('https://www.example.co.uk');
console.log(rootDomain); // 'example.co.uk'

Extract Subdomain

This feature allows you to extract the subdomain from a given URL. In the example, the subdomain 'blog' is extracted from the URL 'https://blog.example.co.uk'.

const tldts = require('tldts-core');
const subdomain = tldts.getSubdomain('https://blog.example.co.uk');
console.log(subdomain); // 'blog'

Extract TLD

This feature allows you to extract the top-level domain (TLD) from a given URL. In the example, the TLD 'co.uk' is extracted from the URL 'https://www.example.co.uk'.

const tldts = require('tldts-core');
const tld = tldts.getPublicSuffix('https://www.example.co.uk');
console.log(tld); // 'co.uk'

Validate Domain

This feature allows you to validate whether a given domain is valid. In the example, the domain 'example.co.uk' is validated and returns true.

const tldts = require('tldts-core');
const isValid = tldts.isValid('example.co.uk');
console.log(isValid); // true
