Single-Page Application is the defining architectural style in Commerce Store Accelerator. Single-page applications are native web applications; that is, they are applications that run natively in a web browser. With single-page applications, the application is served directly to the browser for execution. This contrasts with conventional web applications where the browser is served the result of an application run on the server. Single-page applications are often (but not exclusively) client-server applications, connected to the server through (RESTful) web service APIs.
