Single Page Applications (SPAs)

A Single Page Application (SPA) is an application consisting of a single page whose resources are loaded dynamically as needed, eliminating the need to reload the entire page in the browser with each new user action.

It’s a type of application designed for pages where most of the information is expected to remain the same, with only some fragments being updated at a time.

The goal of an SPA is to achieve smoother and faster navigation, optimize resource usage, and overall improve the user experience.

The most commonly used language for developing an SPA is JavaScript, as it can be used on both the client and server sides with Node.js.

Through the use of an API, an SPA can interact with backend services developed in different languages besides Node.js.

The three main JavaScript frameworks used for developing SPA applications are React, Angular, and Vue. The choice of framework depends on the project and its specific requirements.

Some examples of popular SPA websites include Facebook, Google Maps, Gmail, Netflix, Airbnb, Dropbox, Paypal, and Pinterest.
