vercel-workflow

Build durable, resumable workflows that survive restarts, deployments, and failures using TypeScript directives.

| "use workflow" | Orchestrates steps, sleeps, suspends | Deterministic: No side effects, no Node.js modules, no global fetch | | "use step" | Contains business logic, I/O, side effects | Runs on separate request: Auto-retries on failure |

Workflow DevKit uses event sourcing - state changes are stored as events and replayed to reconstruct state. Workflows must be deterministic so replays produce identical step sequences. Steps run on separate requests, so data passes by value (mutations don't affect workflow variables).

使用「使用工作流程」和「使用步驟」指令，透過 Vercel Workflow DevKit 建立持久的工作流程。用於長時間運行的任務、後台作業、AI 代理、Webhook、排程任務、重試和工作流程編排。支援 Next.js、Vite、Astro、Express、Fastify、Hono、Nitro、Nuxt、SvelteKit。 來源：jakerains/agentskills。
