Single-page application

A single page application (SPA) is a web application that runs entirely in the client web browser, typically using a combination of HTML, JavaScript, and CSS. The application modifies the web page's own data structures through its DOM tree, and makes its changes persistent when the user invokes the browser's Save Page command to save the (modified) web page to disk.

A web application like Gmail is not a single-page application because it communicates with a server and database; the application data is not made persistent by saving the page to local storage such as a hard disk.

Like DHTML, LAMP, or Ajax, SPA is not a technology in itself, but a term that refers to the use of a group of technologies together.
