Get domain from URL in JavaScript

While working on a React component for my website, I have had a need to get a domain name from URL string.

Thankfully, modern browsers provide URL API which makes it very easy to read and manipulate URL without the need of using REGEX.

const url = "https://themesharbor.com/downloads/aquene/";
let domain = new URL(url);
domain = domain.hostname;

console.log(domain); //themesharbor.com

There are cases when URL can contain "www" in a domain name.

If you need to extract domain without "www" then it can be done using the replace() method.

const url = "https://www.themesharbor.com/downloads/aquene/";
let domain = new URL(url);
domain = domain.hostname.replace('www.','');

console.log(domain); // themesharbor.com
