URL is not a constructor

I’m trying to work with this library. When I try to use it in a new URL(url) way, it says: Type Error: URL is not a constructor

When I try to use it as function, it says: Type Error: Failed to construct ‘URL’. Please use the ‘new’ operator; this constructor cannot be called as a function.

I’m using node v6.10.3

Yes. But it’s not what @herodrigues or, probably, you, are doing.

const {URL} = require('whatwg-url');

new URL('http://host/');
