A JavaScript library for implementing the Experience API (Tin Can API).

Browser Usage
TinCanJS is available via npm and Bower.
The browser environment is well tested and supports two kinds of Cross Origin requests which is sufficient to cover most versions of Chrome, FireFox, Safari as well as IE 8+. IE 6+ are supported for non-CORS (because they don't support it).
Include one of build/tincan-min.js or build/tincan.js as follows:
<script src="build/tincan-min.js"></script>
Node.js Usage
TinCanJS is available via npm.
The Environment/Node.js wrapper used in this version has a dependency on the 'xhr2' module
which is also available via npm. It is used to allow the interfaces to the underlying LRS
requests to have the same API. As such currently there is no support for synchronous requests
when using this environment.
Install via:
npm install tincanjs
And within code:
var TinCan = require('tincanjs');
Environments
Implementing a new Environment should be straightforward and requires overloading a couple
of methods in the library. There are currently two examples, Environment/Browser
and Environment/Node.
Attachment Support
Sending and retrieving statements with attachments via the multipart/mixed request/response
cycle works end to end with binary attachments in Node.js 4+ and in the typical modern browsers:
Chrome 53+, Firefox 48+, Safari 9+, IE 10+ (current versions at time of implementation, older versions
may work without changes but have not been tested). Attachments without included content (those using
only the fileUrl property) should be supported in all environments supported by the library.
Several polyfills (TypedArrays, ArrayBuffer w/ slice, Blob, TextDecoder/TextEncoder) are needed
to support various browser versions, if you are targeting a recent enough set of browsers you
can reduce the overall size of the built library by commenting out those polyfills in the
Gruntfile.js file and building yourself.
