On the SitePoint PHP blog there's a new tutorial posted (by Daniel Sipos) about combining Drupal and AngularJS to make for more front-end focused, responsive applications.

Angular.js is the hot new thing right now for designing applications in the client. Well, it’s not so new anymore but is sure as hell still hot, especially now that it’s being used and backed by Google. It takes the idea of a JavaScript framework to a whole new level and provides a great basis for developing rich and dynamic apps that can run in the browser or as hybrid mobile apps. In this article I am going to show you a neat little way of using some of its magic within a Drupal 7 site. A simple piece of functionality but one that is enough to demonstrate how powerful Angular.js is and the potential use cases even within heavy server-side PHP frameworks such as Drupal.

He walks you through the creation of a simple addition of a block that lists out the titles of some other nodes. You'll need an existing Drupal installation to follow along (no setup instructions here) as well as an Angular structure for a small application. He starts with the module configuration and creates custom handling to return the JSON result back to the waiting JS connection. Then he creates the custom template and block that the AngularJS will output the results too. Finally, with that rendering, he glues them both together in an Angular controller that loads the results when an "Open" button is clicked.
