## Directly import \`waitUntil\` in Workers for easily spawning background tasks

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

You can now import [`waitUntil`](https://developers.cloudflare.com/workers/runtime-apis/context/#waituntil) from `cloudflare:workers` to extend your Worker's execution beyond the request lifecycle from anywhere in your code.

Previously, `waitUntil` could only be accessed through the [execution context](https://developers.cloudflare.com/workers/runtime-apis/context/) (`ctx`) parameter passed to your Worker's handler functions. This meant that if you needed to schedule background tasks from deeply nested functions or utility modules, you had to pass the `ctx` object through multiple function calls to access `waitUntil`.

Now, you can import `waitUntil` directly and use it anywhere in your Worker without needing to pass `ctx` as a parameter:

```js
import { waitUntil } from "cloudflare:workers";

export function trackAnalytics(eventData) {
	const analyticsPromise = fetch("https://analytics.example.com/track", {
		method: "POST",
		body: JSON.stringify(eventData),
	});

	// Extend execution to ensure analytics tracking completes
	waitUntil(analyticsPromise);
}
```

This is particularly useful when you want to:

- Schedule background tasks from utility functions or modules
- Extend execution for analytics, logging, or cleanup operations
- Avoid passing the execution context through multiple layers of function calls

```js
import { waitUntil } from "cloudflare:workers";

export default {
	async fetch(request, env, ctx) {
		// Background task that should complete even after response is sent
		cleanupTempData(env.KV_NAMESPACE);
		return new Response("Hello, World!");
	}
};

function cleanupTempData(kvNamespace) {
	// This function can now use waitUntil without needing ctx
	const deletePromise = kvNamespace.delete("temp-key");
	waitUntil(deletePromise);
}
```

Note

The imported `waitUntil` function works the same way as [`ctx.waitUntil()`](https://developers.cloudflare.com/workers/runtime-apis/context/#waituntil). It extends your Worker's execution to wait for the provided promise to settle, but does not block the response from being sent to the client.

For more information, see the [`waitUntil` documentation](https://developers.cloudflare.com/workers/runtime-apis/context/#waituntil).
