Workflow SDK now supports Tan
Original: Workflow SDK now supports TanStack Start
Short summary
Vercel's Workflow SDK now supports TanStack Start applications built on Vite and Nitro. Developers add the workflow plugin to vite.config.ts and write durable workflows using 'use workflow' and 'use step' directives. These operations survive restarts, retry on failure, and maintain state automatically. The SDK handles all infrastructure—compilation, queuing, persistence—transparently.
