Cloudflare Frameworks

Cloudflare Workers run V8 isolates, not Node.js. This changes which frameworks work well on the platform and how you build with them. This guide covers 10 frameworks and approaches for deploying web apps to Cloudflare, from full SSR to static SPAs, with setup commands, binding access patterns, and honest trade-offs.

Overview

• Platform: Cloudflare Workers (V8 isolates, workerd runtime)
• Key shift: Cloudflare is migrating from Pages to Workers with Static Assets
• Infrastructure: The Cloudflare Vite Plugin (@cloudflare/vite-plugin) is the unifying dev story
• Auto-deploy: npx wrangler deploy auto-detects frameworks, generates config, installs adapters
• Frameworks covered: React Router v7, Astro, SvelteKit, TanStack Start, Hono, Next.js (OpenNext), Nuxt, Qwik City, SolidStart, Vite+React SPA
