Check if a URL is absolute
By default, it checks if the URL uses the http or https protocol.
$ npm install is-absolute-url
const isAbsoluteUrl = require('is-absolute-url');
isAbsoluteUrl('https://sindresorhus.com/foo/bar');
//=> true
isAbsoluteUrl('http://sindresorhus.com/foo/bar');
//=> true
isAbsoluteUrl('ftp://sindresorhus.com/foo/bar');
//=> false
isAbsoluteUrl('ftp://sindresorhus.com/foo/bar', {httpOnly: false});
//=> true
isAbsoluteUrl('//sindresorhus.com');
//=> false
isAbsoluteUrl('foo/bar');
//=> falseBy default only http and https links are validated. If you wish to check absolute URLs of protocols other than http (for example, ftp:, mailto:), use isAbsoluteUrl(mayBeURL, { httpOnly: false }).
