Parse URL without protocol in Node using constructor

Question

How can I parse successfully www.stackoverflow.com as a URL using the WHATWG URL API in NodeJS?

If I try new URL("www.stackoverflow.com") I get the error error: URL constructor: www.stackoverflow.com is not a valid URL .

Note: url.parse is deprecated

Answer 1

Simply do this:

const parsedURL = new URL(url.startsWith("http") ? url : `https://${url}`);
