Another nifty new tool is WP-API, a RESTful interface for interacting with WordPress. This is exactly the bridge needed to power an AngularJS application’s server side data.
To provide a flexible way to use WP-API with AngularJS, I’ve written a module that can be easily included in your AngularJS application’s dependency array, and accessed via a $resource.
The module requires some localized data from WordPress, so I’ve included a plugin file you can use as an example or install and activate. Much more information is in the README.
