Original generates the origin URL for a given URL or URL object. In addition to that it also comes with a simple same function to check if two URLs have the same origin.

This module is browserify and node compatible and is therefore released in the npm registry and can be installed using:

npm install --save original

In all the examples we assume that the module is loaded using:

'use strict';

var origin = require('original');

To get the origin of a given URL simply call origin function with any given URL to get origin.

var o = origin('https://google.com/foo/bar?path');

// o = https://google.com

To compare if two URLs share the same origin you can call the same method.

if (origin.same('https://google.com/foo', 'https://primus.io')) {
  console.log('same');
} else {
  console.log('guess what, google.com and primus.io are not the same origin');
}

And that's it.
