Cloudflare Workflows

Implement stateful workflows with Cloudflare Workflows

Cloudflare Workflows Example

This example demonstrates using Cloudflare Workflows for stateful, long-running processes. The workflow example is included in the comprehensive Cloudflare Worker example.

Features

• Workflows: Stateful workflow orchestration
• OFAC Processing: Example compliance workflow
• Worker Integration: Workflows bound to Workers
• Durable Execution: Guaranteed workflow completion

Project Setup

Key Features Explained

Workflow Definition

Workflows are defined with a class name and workflow name:

Workflow("OFACWorkflow", {
  className: "OFACWorkflow",
  workflowName: "ofac-workflow",
})

Workflow Steps

Steps provide durability guarantees:

const result = await step.do("step-name", async () => {
  // This code runs exactly once
  return { data: "result" };
});

Sleep/Delays

Workflows can pause execution:

await step.sleep("wait-for-response", 1000);

Instance Management

Create and manage workflow instances:

const instance = await env.WORKFLOW.create({ id: "unique-id" });
const status = await instance.status();

Use Cases

• Compliance workflows (OFAC, KYC)
• Multi-step approval processes
• Long-running data processing
• Saga pattern implementations
• Retry-able operations with state
