Building Ultra-Fast Edge Web Apps with React 19, Vite, and Cloudflare Pages

Deploying web applications to centralized origin servers introduces geographic latency for global users. By compiling static bundles and deploying to Cloudflare Pages, every page asset, HTML document, and API worker is distributed across 300+ edge data centers worldwide. A user in Tokyo, Frankfurt, or Austin receives assets within 15ms of DNS resolution.

While Client-Side Rendered (CSR) Single Page Applications offer smooth in-app transitions, search crawlers and ad networks (such as Google AdSense and Bingbot) frequently penalize empty initial HTML shells. In RadTome's build pipeline, we use `@prerenderer/rollup-plugin` with headless Puppeteer to generate fully realized static HTML files for every route during the Vite build:

// vite.config.js prerender setup
prerender({
  routes: ['/', '/about', '/privacy', '/terms', '/contact', '/articles'],
  renderer: '@prerenderer/renderer-puppeteer',
  rendererOptions: {
    renderAfterTime: 500,
    maxConcurrentRoutes: 1
  }
})

All JavaScript, CSS, and media assets generated by Vite include 8-character content hashes in their filenames (`index-BmGnH9Hg.js`). This enables Cloudflare Pages to serve assets with an aggressive `Cache-Control: public, max-age=31536000, immutable` header, ensuring repeat visitors load the site entirely from local browser disk cache.
