## Call Workflows declared in \`exports\` through \`ctx.exports\`

[Workflows](https://developers.cloudflare.com/workflows/) [Workers](https://developers.cloudflare.com/workers/)

A Worker can now call the Workflows it declares in the [`exports`](https://developers.cloudflare.com/workers/wrangler/configuration/#workflow-exports) field of its Wrangler configuration through [`ctx.exports`](https://developers.cloudflare.com/workers/runtime-apis/context/#exports). You no longer need a `workflows` binding to call a Workflow from the Worker that defines it.

Each Workflow is keyed by class name, and has the same API as a Workflow binding:

*src/index.jsjs*

```js
export default {
	async fetch(request, env, ctx) {
		const instance = await ctx.exports.MyWorkflow.create({
			params: { name: "World" },
		});
		return Response.json({ id: instance.id });
	},
};
```

*src/index.tsts*

```ts
export default {
	async fetch(request, env, ctx): Promise<Response> {
		const instance = await ctx.exports.MyWorkflow.create({
			params: { name: "World" },
		});
		return Response.json({ id: instance.id });
	},
} satisfies ExportedHandler<Env>;
```

A `workflows` binding and a `workflow` export with the same `name` share their instances. You can move a Workflow from a binding to an export without losing its instances.

`wrangler dev`, the [Cloudflare Vite plugin](https://developers.cloudflare.com/workers/vite-plugin/), and the [Workers Vitest integration](https://developers.cloudflare.com/workers/testing/vitest-integration/) run Workflows on `ctx.exports` locally. Local development requires Wrangler 4.142.0, `@cloudflare/vite-plugin` 1.61.0, or `@cloudflare/vitest-plugin` 1.3.0 or above.

In Vitest, `introspectWorkflow()` and `introspectWorkflowInstance()` still need a Workflow binding. To introspect a Workflow declared in `exports`, add a [test-only binding](https://developers.cloudflare.com/workers/testing/vitest-integration/test-apis/#introspect-workflows-declared-in-exports) to it.
