This set of Arena modules enables a user to authenticate in Arena using their Facebook account.
Clone the repository into your working Arena directory, or download the zip or tarball and unzip it into your working Arena web directory. The wiki on Redmine has some helpful information on how this functionality lays out.
This module set does have an external dependency on the Facebook C# API in NuGet version ~5.2.*. Please note that this is an older version. Installing the latest (6.1.*) might require some refactoring to get it to work properly. This can be installed via the NuGet Package Manager that comes integrated with Visual Studio.
The web service and module code files also reference a couple additional dependencies on Central's FrameworkUtils and DataUtils projects. FrameworkUtils has a dependency on DataUtils. The source code for those projects can be found here, and will likely need to be refactored to run against Arena 2012. or later if you're on a current version of Arena ChMS.*
The client side code is all written in CoffeeScript. If you need to build it, you'll want to install Node and run npm install -g coffee-script to install the CoffeeScript compiler. You can then cd into the usercontrols/custom/cccev/web folder and run coffee -j scripts/centralaz.facebook.js -c coffeescripts/lib/facebook/. Alternatively in Windows, you can try using the Mindscape Web Workbench plugin for Visual Studio.
The CoffeeScript source files are located in usercontrols/custom/cccev/web/coffeescripts/lib. There are unit tests written in Jasmine that can be executed via the test runner located in usercontrols/custom/cccev/web/spec/run/SpecRunner.html. The spec source is also written in CoffeeScript found at usercontrols/custom/cccev/web/coffeescripts/spec/lib/facebook.
