Node.js URL.host API

The URL.host property in Node.js represents the hostname and port number of a URL. In this article, we will discuss how to use the URL.host property in Node.js.

Syntax

The syntax for using the URL.host property in Node.js is as follows:

urlObject.host

Here, urlObject is the URL object returned by the URL() constructor.

Example

Let's suppose we have a URL https://www.example.com:8080/path/to/my/resource.html. To get the hostname and port number from this URL, we can use the URL.host property as follows:

const { URL } = require('url');
const myUrl = new URL('https://www.example.com:8080/path/to/my/resource.html');
const host = myUrl.host;

console.log(host); // output: www.example.com:8080

Here, we first import the URL module from the url package. We then create a new URL object from the given URL. Finally, we retrieve the host property of this object and log it to the console.

Conclusion

In this article, we have discussed the basics of using the URL.host property in Node.js. By using this property, we can easily retrieve the hostname and port number of a given URL.
