Web application

Last edited on April 13, 2026 · What links here

In the broader sense, the term "web application" refers to both the browser-side frontend and the server-side backend (typically a REST API) that work together to deliver the web service experience. In the narrow sense, the term "web application" refers specifically to the browser-side program — the JavaScript single-page application (SPA) running in a tab. Which reading is meant usually depends on context.
