@tanstack/workflow-store-cloudflare-d1

Experimental Cloudflare D1 durable execution store for TanStack Workflow.

This adapter implements the WorkflowExecutionStore contract from @tanstack/workflow-runtime using a Cloudflare D1 binding.

Usage

pnpm add @tanstack/workflow-store-cloudflare-d1

import { createCloudflareD1WorkflowStore } from '@tanstack/workflow-store-cloudflare-d1'

export interface Env {
  WORKFLOW_DB: D1Database
}

export default {
  async scheduled(_event, env) {
    const store = createCloudflareD1WorkflowStore({ db: env.WORKFLOW_DB })
    // pass store to defineWorkflowRuntime(...)
  },
}

Apply the package-owned D1 migration during setup/deploy:

wrangler d1 migrations apply WORKFLOW_DB

The SQL artifact lives at:

node_modules/@tanstack/workflow-store-cloudflare-d1/migrations/0000_workflow_store.sql

store.ensureSchema() remains available for tests, local demos, and explicit admin bootstrap scripts. Production deploys should prefer Cloudflare D1 migrations so schema changes are reviewed and repeatable.
