deployment

Install @cloudflare/vite-plugin and wrangler, add the cloudflare plugin before tanstackStart in vite.config.ts, and create a wrangler.jsonc with the nodejs_compat compatibility flag. Deploy with npx wrangler login followed by pnpm run deploy.

Set ssr: false on the route definition to run loaders and render the component only on the client. Use ssr: 'data-only' to run loaders on the server while rendering the component on the client, or pass a function for runtime decisions.

Yes, enable prerender in the tanstackStart Vite plugin config with enabled: true and crawlLinks: true to generate static HTML at build time. Dynamic routes require crawlLinks or an explicit pages configuration to be discovered.

Cloudflare Workers inject environment variables per request, so process.env at module scope evaluates to undefined. Import env from cloudflare:workers or read process.env inside handler or middleware server functions instead.

No, Bun deployment requires React 19 via the nitro bun preset. For React 18 projects, use the standard Node.js deployment target instead.

Child routes inherit parent SSR config and can only be more restrictive, not less. A child cannot upgrade from a parent's ssr: false to ssr: true; the parent's stricter setting always wins.
