Web Development Intermediate

What is SPA (Single Page Application)?

A web application that loads a single HTML page and dynamically updates content without full page reloads.

SPAs load once and use JavaScript to render content dynamically. Navigation happens client-side using the History API, creating a smooth, app-like experience without page refreshes. Data is fetched via AJAX/fetch API calls.

Popular SPA frameworks include React, Vue.js, and Angular. Challenges include SEO (solved by SSR/SSG), initial load time (code splitting), and browser history management. SPAs communicate with backends via REST or GraphQL APIs.
