Single Page Application
A Single Page Application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from a server. This approach provides a more fluid, app-like user experience by avoiding page reloads and enabling faster transitions between views. SPAs typically rely on JavaScript frameworks to manage client-side routing, state, and data fetching from APIs.
Developers should use SPAs when building interactive web applications that require fast, seamless user interactions, such as dashboards, social media platforms, or productivity tools. They are ideal for projects where user experience prioritizes responsiveness and where server load needs to be reduced by offloading rendering to the client. SPAs also facilitate building progressive web apps (PWAs) that can work offline and provide native-like features.
