New Instance Lifecycle Methods in Local Development

Cloudflare Workflows now supports four essential instance management methods in local development environments using wrangler dev:

• pause() - Pauses a running workflow instance
• resume() - Resumes a paused instance
• restart() - Restarts the instance from the beginning
• terminate() - Terminates the instance immediately

Testing the Full Workflow Lifecycle

Developers can now test the complete workflow instance lifecycle locally before deploying to production. This enables comprehensive testing of workflow control flow, state management, and error handling scenarios within the local development environment.

const instance = await env.MY_WORKFLOW.create({
  id: "my-instance-id",
});

await instance.pause();     // pauses a running workflow instance
await instance.resume();    // resumes a paused instance
await instance.restart();   // restarts the instance from the beginning
await instance.terminate(); // terminates the instance immediately

Getting Started

These methods are immediately available when using wrangler dev for local Workflows development. No additional configuration or updates are required—simply use these methods in your local test code.
