JSO – OAuth 2.0 Client with Javascript

• Documentation: Getting Started

OAuth 2.0 from your javascript client web application or mobile application in a secure way. JSO is provided by UNINETT AS, a non-profit company working for educational and research institutions in Norway.

JSO may be used to make your web application (or mobile hybrid application) act as an OAuth 2.0 Consumer/client, and access remote APIs that are protected by OAuth 2.0 and supports CORS (or JSONP).

NOTICE: Version 3 coming up

I'm currently working on a third generation of JSO.

Main features are:

• Build with heavily use of ES6 Promises
• Support for various loaders (hidden iframes, popup, passive, active)
• Adding support for doing authentication (OpenID Connect, and others)

It is already available for testing

Features

• Registered with bower.io
• Implements OAuth 2.0 Implicit Flow.
• AMD-compatible loading.
• Supports the Bearer access token type.
• No server component needed.
• Adds an wrapper for to use $.ajax() as you're used to.
• Can handle multiple providers at once.
• Uses HTML 5.0 localStorage to cache Access Tokens. You do not need to implement a storage.
• Can prefetch all needed tokens with sufficient scopes, to start with, then tokens can be used for requests later. This way, you can be sure that you would not need to redirect anywhere in your business logic, because you would need to refresh an expired token.
• Excellent scope support.
• Caches and restores the hash, your application will not loose state when sending the user to the authorization endpoint.

Dependencies

No external dependencies. Plays well with jQuery though.

Browser support

JSO uses localStorage for caching tokens. localStorage is supported in Firefox 3.5+, Safari 4+, IE8+, and Chrome. For better compatibility use the localstorage library that is included in the example.

JSO uses JSON serialization functions (stringify and parse). These are supported in Firefox 3.5, Internet Explorer 8.0 and Chrome 3. For better compatibility use the JSON2.js library.
