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“使用步骤”指令，通过 Vercel Workflow DevKit 构建持久的工作流程。用于长时间运行的任务、后台作业、AI 代理、Webhook、计划任务、重试和工作流编排。支持 Next.js、Vite、Astro、Express、Fastify、Hono、Nitro、Nuxt、SvelteKit。 来源：jakerains/agentskills。
