Package Exports

isurl

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (isurl) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isurl

Determines whether a value is a WHATWG URL.

Works cross-realm/iframe and despite Symbol.toStringTag.

Installation

Node.js >= 8 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 origin, searchParams and toJSON properties (which are common in many modern web browsers):

const url = new URL('http://domain/?query');

console.log(url.searchParams);  //-> undefined

isURL.lenient(url);  //-> true
