As web sites are becoming ever more dynamic and interactive, they turn more application-like.
Responsiveness is everything when building modern web applications. For this reason, client-side web frameworks do not reload the entire page whenever a user clicks something.
Ember.js is known from, among other things, the Discourse project, and is minded towards ambitious web frameworks. It is a full-stack, browser-side MVC framework. It handles routing based on URL, rendering of templates and business logic, all in the browser.
When building Ember.js applications, it is still necessary with a server-side backend that handles access control, provides admin interfaces, etc., and Drupal is well suited for this purpose.
I will also dive into how Drupal can be used to bootstrap the Ember.js app to increase the performance of the initial page load, as well as interactive pagination, lazy-loading and other UX and performance tweaks to make your web application more responsive.
