SPA

Single-Page Application

Definition

An SPA loads a single HTML shell and dynamically renders all subsequent content using JavaScript, with navigation handled client-side without full page reloads. React, Angular, and Vue are the dominant SPA frameworks.

SPAs provide rich interactive UIs but have slower initial load times and require additional work for SEO. The trend is moving toward hybrid rendering (SSR + hydration) to address these limitations.
