SINGLE-PAGE APPLICATION

A single-page application (SPA) is a web application  that fits on a single web page with the goal of providing a user experience similar to that of a desktop application . In an SPA, either all necessary code – HTML, JavaScript, and CSS – is retrieved with a single page load.
JavaScript frameworks
Web browser JavaScript frameworks, such as AngularJS, Ember.JS,Meteor.JS, ExtJs and React have adopted SPA principles.

• AngularJS is a fully client-side framework. AngularJS’s templating is based on bidirectional UI data binding . Data-binding is an automatic way of updating the view whenever the model changes, as well as updating the model whenever the view changes. The HTML template is compiled in the browser. The compilation step creates pure HTML, which the browser re-renders into the live view. The step is repeated for subsequent page views. In traditional server-side HTML programming, concepts such as controller and model interact within a server process to produce new HTML views. In the AngularJS framework, the controller and model states are maintained within the client browser. Therefore, new pages are capable of being generated without any interaction with a server.
