Finally, we would like to emphasize some important points that were discussed throughout the book.

The term SPA refers to a main container that carries several templates within itself; something very similar to the concept of master pages in the .NET framework. The following figure illustrates the main difference between SPA and a traditional web application.

SPA can contain a dozen or more templates. This will depend on the complexity of the application. With this concept in mind, if you briefly return to Chapter 4, Creating a Conference Web Application, you can see that we wrote SPA that only ran on the server side, even using an API, much like the traditional way to build dynamic applications in server-side languages such as PHP and .NET.
