angular-uuid is an AngularJS wrapper for Robert Kieffer's node-uuid, which provides simple, fast generation of RFC4122 UUIDS.
- AngularJS service – no global scope pollution
 - Generate RFC4122 version 1 or version 4 UUIDs
 - Cryptographically strong random # generation on supporting platforms
 - Tiny file size when minified.
 
If using CommonJS then simply require angular-uuid as per usual, prior to setting up your AngularJS modules (but after including angular):
npm install --save angular-uuid
require("angular-uuid");Otherwise use a regular script tag (after including angular):
<script src="angular-uuid.js"></script>Ensure that you include angular-uuid in your module definition:
var CoolApp = angular.module("CoolApp", ["angular-uuid"]);You can then inject uuid where necessary, for example:
CoolApp.controller("MainCtrl", ["uuid", MainCtrl]);
function MainCtrl (uuid)
{
    var hash = uuid.v4();
    console.log(hash);
