📖 Usage

Timeout

The most common use case: aborting an operation if it takes too long.

try {
  // Request will fail if it takes longer than 3 seconds.
  const response = await fetch(url, { signal: Abort.timeout(3000) });
} catch (error) {
  if (error instanceof TimeoutError) {
    console.log('Request timed out!');
  }
}

Combining Signals

Abort an operation from one of several sources, like a timeout OR a user click.

const userClickSignal = Abort.fromEvent(cancelButton, 'click');
const timeoutSignal = Abort.timeout(10000);

// Aborts on user click OR timeout, whichever comes first.
const combinedSignal = Abort.any([userClickSignal, timeoutSignal]);
await longRunningOperation({ signal: combinedSignal });

From an Event

Bridge the DOM/event world with the cancellation world.

// Signal will abort as soon as the user navigates away or closes the tab.
const signal = Abort.fromEvent(window, 'unload');
await saveDraftToServer({ signal });
