A Single Page Application (SPA) is a different way of building HTML 5 applications from traditional Web page development. Instead of spreading the functionality of your Web applications across a collection of separate Web pages with hyperlinks between them, you instead define a single root page that the user lands on and never leaves as long as they are working with your application. You define client-side logic that switches out the data and chunks of content within that page to allow the user to navigate from logical screen to logical screen without ever leaving the page. This means that the user never sees a full page refresh while using your application. They see portions of the screen change based on their interaction, and those changes can be done in a more fluid way with transitions to enhance the user experience. You can also support using the application while offline by storing data client-side, based on some of the newer APIs of HTML 5. Taking this approach makes an SPA feel very much like a desktop application to the end user.

The ASP.NET team has created lots of new goodies. One of the most useful, SignalR, is an async library for .NET to help build real-time, multi-user interactive web applications. Imagine this scenario: you have a web application and would like a simple way to push notifications to any number of clients. Perhaps you want to inform the client when something happens. You could write a polling mechanism, but that is inefficient. An event-based approach is a much more efficient approach. Event-based systems that can publish and subscribe to events are typically loosely coupled systems that easily adapt to change and are highly scalable. The SignalR library makes it very easy to build loosely coupled scalable applications that can send real-time updates to specified clients. In this article, I will take you through the some basic steps to get up and running with SignalR.
