A single-page application (SPA), is a web application or web site that fits on a single web page.
The applications generally retrieve their resources as needed from HTML templates for display and from Web services for data.
Single page apps can generally appear to respond quicker. They do this by not having to refresh the page. Instead, they can provide an indication to the user that information is being retrieved, leaving the rest of the page in tact.
Single page apps can store state locally. This means that the user does not necessarily send its state to the server on each refresh. Instead, it can be stored locally and updated to the server asynchronously.
Modern web technologies (such as those included in HTML5) can provide the perception and navigability of separate logical pages in the application. Interaction with the single page application often involves dynamic communication with the web server behind the scenes.
In addition, you can build applications for devices, such as smartphones (iOS, Andriod, and Windows Phone) using single page application technology. In fact, in a well designed architecture, the services may be the same but the HTML templates vary as needed to be appropriate to the device.
A single page app gets its power from a “dance” between the client and the server in getting the ways to display data and getting the data itself.
From Kalyan Bandarupalli‘s post Single Page Applications using ASP.NET
There are few distinct characteristics of the professional Single Page Application:
Asynchronous Module Definition (AMD)
- Namespaces, Anonymous Module, Revealing Module Pattern
- Asynchronous Module Definition (AMD)
- Inheritance Using Revealing Module Pattern
- Getting Started with Modules Using RequireJS
- Using RequireJS Asynchronous Module Definition (AMD) Modules with jQuery, LoDash
- Loading, Caching LoDash or Underscore Templates Using RequireJS, AppCache
- Fixing Errors When Using jQuery, Sammy, RequireJS
- Asynchronous Programming Using Promises
- Promises for Asynchronous Operations Using jQuery
- Asynchronous Sample Using jQuery Promise to Render JSON Using Mustache
- Using Q Promises Inside a RequireJS AMD Module
The goal of our sample code is to provide something that works, where you can understand the context and how the pieces fit together.
