Build full-stack React applications with TanStack Start on Cloudflare Workers. Type-safe routing, server functions, SSR/streaming, and seamless D1/KV/R2 integration.Use when: building full-stack React apps, need SSR with Cloudflare Workers, want type-safe server functions, or migrating from Next.js.RC status - v1.0 stable pending. Monitor tanstack/router#5734 (memory leak) before production use.
When & Why to Use This Skill
This Claude skill empowers developers to architect and build high-performance, full-stack React applications using TanStack Start on Cloudflare Workers. It provides expert guidance on implementing type-safe routing, server functions, and streaming SSR, while ensuring seamless integration with Cloudflare's edge services like D1, KV, and R2. Ideal for developers seeking a modern, Vite-powered alternative to Next.js with superior type-safety.
Use Cases
- Building edge-native full-stack React applications with server-side rendering (SSR) on Cloudflare Workers.
- Migrating existing Next.js or Vite-based projects to the TanStack Start framework for enhanced type-safety and performance.
- Implementing type-safe server functions and API routes that interact directly with Cloudflare D1 databases and R2 storage.
- Developing complex web applications requiring file-based routing, hydration management, and optimized streaming SSR.
