2 JavaScript SPA Examples

This collection is a complete guide to building Single-Page Applications (SPAs) without frameworks. At its core is a client-side router based on the History API (pushState), which prevents page reloads. Content for each route is loaded asynchronously using the Fetch API and dynamically injected into the DOM. To create a seamless user experience, CSS animations are orchestrated to ensure smooth transitions between “pages.” This architectural pattern allows for creating fast, performant web applications with a native feel.
