## Prevent Durable Object alarm retries when using \`ctx.abort()\`

[Durable Objects](https://developers.cloudflare.com/durable-objects/)

By default, an alarm interrupted by `ctx.abort()` retries after the Durable Object resets. Pass `{ retryAlarm: false }` when the alarm should stop instead:

*src/index.jsjs*

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

export class CleanupTask extends DurableObject {
	async alarm() {
		await this.ctx.storage.deleteAll();

		this.ctx.abort("Cleanup complete", { retryAlarm: false });
	}
}
```

*src/index.tsts*

```ts
import { DurableObject } from "cloudflare:workers";

export class CleanupTask extends DurableObject {
	async alarm(): Promise<void> {
		await this.ctx.storage.deleteAll();

		this.ctx.abort("Cleanup complete", { retryAlarm: false });
	}
}
```

For example, an alarm that deletes its storage can use this option to avoid repeating the cleanup or re-running the Durable Object constructor.

Alarms can run concurrently with other requests to the same Durable Object. If another request calls `ctx.abort()` while an alarm is running, the `retryAlarm` option on that call also controls whether the alarm retries.

The default retry prevents an unrelated request from permanently canceling the alarm. Set `retryAlarm: false` on every abort path that should stop an in-progress alarm, not only on calls from the alarm handler. Existing calls to `ctx.abort()` keep retrying alarms.

For local development, `retryAlarm` requires Wrangler 4.126.0 or later.
