AngularJS's architecture is a perfect fit to decouple parts or the whole front end of Drupal.

There are three main reasons to decouple the frontend:

1. Give front end folks full power to write the HTML and CSS they want.
2. Allow pages to be served by reverse proxies and render dynamic parts of it with AngularJS.
3. Decoupling the front end from Drupal makes core upgrades less cumbersome.

We will go over some examples from MSNBC, a project where we decoupled a lot of areas from Drupal with AngularJS with tremendous success. We will also see some attempts we have made to build fully decoupled and authenticated websites.
