angular-uuid4

Angular service that generates RFC4122 version 4 UUIDs / GUIDs.

Sample UUID: f7e81995-1a52-48a4-88d1-f979e1917b29

Based on this stack overflow post but uses Date.now() instead of new Date().getTime() for better performance.

Usage

Require the module in your app and call uuid4.generate().

Example:

// add the uuid4 module to your app
myapp = angular.module('myapp', ['uuid4']);

// inject it into your component
myapp.factory('FancyFactory', function(uuid4){
  return {
    codeThatNeedsUUID: function() {
      return "Look ma! I'm unique: " + uuid4.generate();
    }
  };
});

Collisions

There are reports of Math.random() not working properly on some systems. This causes collisions (UUIDs that are the same). This code uses both Math.random() and Date.now() to generate the UUID in order to minimize the chance of collisions.
