Node.js urlObject.auth API

The urlObject.auth API is a part of the built-in url module in Node.js. The auth property of a URL object is used to get or set the username and password in a URL.

Getting Started

To use the urlObject.auth API, first, we need to create a URL object using the url.parse() method which is also a part of the built-in url module.

const url = require('url');

const myUrl = url.parse('https://username:password@example.com');
console.log(myUrl.auth); // username:password

In the above example, we have created a URL object called myUrl using the url.parse() method. We have passed a URL string containing a username and password to the url.parse() method. Then we have accessed the auth property of the myUrl object using myUrl.auth which returns the username and password in the format of username:password.

Setting Username and Password

We can also set the username and password in a URL using the urlObject.auth API. To set the username and password, we need to pass the string in the format of username:password as the value of the auth property.

myUrl.auth = 'newusername:newpassword';
console.log(myUrl.href); // https://newusername:newpassword@example.com/

In the above example, we have set the username and password in the myUrl object using the auth property. Then we have accessed the href property of the myUrl object which returns the updated URL string containing the new username and password.

Conclusion

The urlObject.auth API in Node.js is very useful when working with URLs that contain a username and password. It provides a way to get or set the username and password in a URL. To get started with urlObject.auth, create a URL object using the url.parse() method and then access or set the auth property of the URL object.
