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

Aug 08, 2025 

[ 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:

**JavaScript**

```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

**JavaScript**

```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).
