Single-page applications (SPA)

A single-page application is a web application that has one HTML input file and the content is stored on one web page.

This architecture makes SPAs more interactive and user-friendly than traditional web applications.

The principle of single-page applications can be simplistically described as follows: the user enters the URL of the application into the browser, the application data is downloaded to the browser, and the data is dynamically refreshed based on user interactions-without the need to constantly download all the data from the server.

This approach makes SPAs more agile and able to respond more quickly to user requests. They also partially eliminate the need for an Internet connection.
