Single Page Applications – Definition, functionality, and benefits
Interactive websites are no longer a rarity today; they are simply part of everyday Internet use. Multi page applications were often used in the past. These consist of many different individual web pages or HTML documents, but, on the contrary, single page applications consist of only one web page.

What is a single page application?
A single page application is a very modern way to create dynamic websites. Nowadays, creating static websites is no longer a problem with the help of static site generators. However, these websites still require several HTML documents.
The entire World Wide Web is based on interactions between servers and clients. Web browsers, such as Google Chrome or Safari, act as users (clients), and send so-called HTTP requests to the respective web server. All data that is important for the web application is stored on this server. The server responds to the client’s request with a response and makes the requested data available.
How a single page application works
During a user interaction, data in JSON or XML format is loaded in the background and is invisible to the user. These are then automatically inserted into the DOM of the loaded web page. In this way, the entire presentation logic of the web application is executed directly on the client’s side, namely in the browser. The server only provides data, not entire web pages.
When are single page applications used?
A single page application is particularly helpful when the server load is to be reduced. This can be useful not only for large websites like Facebook or Twitter, but even for smaller online stores. If it’s a website that users access frequently, short runtimes are particularly important. It therefore makes sense, for example, to program computer games that run in the web browser as single page applications. Web applications that are to be available as apps on mobile devices should ideally be designed as single page applications. This makes it possible to use the same backend for the mobile app and website, which reduces the programming effort.

Deploying single page applications with GitHub
Using version control systems like GitHub offers a number of advantages. In particular, they facilitate the work for the development team as well as make it easier to manage different code versions. A single page application’s code can be easily deployed to a GitHub repository. Once you’ve committed your code to GitHub, it’s easy to use a server to run realistic live tests during the development process.
