Node.js urlObject.host API

Last Updated : 14 Oct, 2021

The utilities for URL resolution and parsing is provided by the URL module.
A URL string is a structured string that contains various multiple meaningful components. When parsed, a URL object is returned that contains properties for each of these components.

url.host() return the host name in the url as a string.
Examples:

http://localhost:8080/register
localhost:8080 - is the host name.

https://geeksforgeeks.org/practice geeksforgeeks.org - is the host name.

In the below example we first create a URL object. Then after using the .host() function, we will get the hostname in the URL as output.

//Importing the url module

const url=require('url');

//creating a new url object

var link = new URL("https://google.com/coding_challenges");

//Using the .host() function to print the host name in the url

console.log(link.host);

OUTPUT: google.com
