What is Single Page Application (SPA)?

A Single Page Application (SPA) is a web application that loads a single HTML page and dynamically updates its content as the user interacts with the application, without requiring a full page reload. 

This approach is different from traditional web applications, where clicking on a link or button would cause the browser to request a new page from the server, which would then be rendered in the browser.

In a SPA, the initial HTML, CSS, and JavaScript are loaded from the server, and subsequent interactions with the application are handled by the JavaScript running on the client side. This allows faster and more responsive user interfaces, as well as a more seamless user experience.

SPAs often use some frameworks to manage the client-side code and handle the dynamic updating of content. They also often rely on web APIs, such as RESTful APIs, to interact with server-side data and services.

Some commonly used SPA frameworks are-

• React
• Angular
• Vue.js
