A Single-Page Application (SPA) is a web application or web site that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from a server. This approach avoids interruption of the user experience between successive pages, making the application behave more like a desktop application.

In a SPA the appropriate resources are dynamically loaded and added to the page as necessary, usually in response to user actions. The page does not reload at any point in the process, nor does control transfer to another page, although the location hash or the HTML5 History API (using one or the other based on your Vue Router mode in the /quasar.config file) can be used to 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.
