 SvelteKit, Nuxt, Analog, and Astro handle their own error pages and ignore `routing.notFound`. For direct Cloudflare deployment with TanStack Start, React Router, or vinext, configure the asset binding, directory, and routing policy through the framework's Cloudflare config.
 
+With `void deploy --platform cloudflare`, SvelteKit, Nuxt, Analog, and Astro apps serve built files and prerendered pages without starting the Worker, and requests without a matching file reach the framework. To start the Worker first for other paths, set [`run_worker_first`](https://developers.cloudflare.com/workers/static-assets/binding/#run_worker_first) under `cloudflare.assets` in `void.config.ts`. With `true`, every request starts the Worker and counts toward its request usage.

 ## API routes and SSR pages
 
 API responses and SSR pages are not cached as static assets. Use [Revalidation](./revalidation) to cache public rendered pages.
