# signal

A signal object allowing you to cancel the request.

## Declaration

```data
signal?: AbortSignal;
```

## Discussion

Discussion Pass an AbortSignal from an AbortController to allow the controller to cancel a pending directions request. When the controller aborts, the promise it returns rejects with a DOMException whose name is "AbortError". const controller = new AbortController(); const directions = new mapkit.Directions();

try {     const response = await directions.route({         origin: "San Francisco",         destination: "Los Angeles",         signal: controller.signal,     }); } catch (error) {     if (error.name === "AbortError") {         // The request was canceled.     } }

// Cancel the request at any time: controller.abort();
