    What Makes This JS-Heavy

    Every feature below demonstrates a different JavaScript rendering pattern that prerender services must handle correctly.

    ⚡

    Client-Side Rendering

    Every piece of content on this page is rendered by JavaScript at runtime. No server-side HTML is generated — making it ideal for prerender testing.

    Dynamic Image Loading

    Images are lazy-loaded with IntersectionObserver patterns and rendered through JavaScript imports and state management.

    State-Driven UI

    Filters, tabs, counters, and interactive elements all depend on React state. Content changes dynamically based on user interactions.

    Animations & Transitions

    Framer Motion powers smooth enter/exit animations, layout transitions, and scroll-triggered effects throughout the page.

    Dynamic Data Rendering

    Simulated API responses, computed values, and dynamically generated content test complex data rendering scenarios.

    Component Architecture

    Modular React components with props, children, and composition patterns create a realistic single-page application structure.

    How It Works

    Tabbed content rendered entirely by JavaScript. Each tab swap is a state change — no server round-trips involved.

    Single Page Application

    This demo is a fully client-side rendered React application. The entire DOM is constructed by JavaScript after the initial HTML shell loads. Without prerendering, search engine crawlers would see an empty page with just a root div element.

    // What crawlers see without prerender:
<html>
  <body>
    <div id="root"></div>
    <script src="/assets/index.js"></script>
  </body>
</html>

// What prerender captures:
<html>
  <body>
    <div id="root">
      <section class="hero">...</section>
      <section class="stats">...</section>
      <!-- Full rendered content -->
    </div>
  </body>
</html>
