isurl 
Checks whether a value is a WHATWG
URL.
Works cross-realm/iframe and despite @@toStringTag.
Installation
Node.js >= 4 is required. To install, type this at the command line:
npm install isurl
Usage
const isURL = require('isurl');
isURL('http://domain/'); //-> false
isURL(new URL('http://domain/')); //-> true
Optionally, acceptance can be extended to incomplete URL implementations that lack searchParams (which are common in many modern web browsers):
const url = new URL('http://domain/?query');
console.log(url.searchParams); //-> undefined
isURL.lenient(url); //-> true
