AbortSignal: any() static method

The AbortSignal.any() static method takes an iterable of abort signals and returns an AbortSignal. The returned abort signal is aborted when any of the input iterable abort signals are aborted. The abort reason will be set to the reason of the first signal that is aborted. If any of the given abort signals are already aborted then so will be the returned AbortSignal.





An iterable (such as an Array) of abort signals.

Return value

A AbortSignal that is:

  • Already aborted, if any of the abort signals given is already aborted. The returned AbortSignal's reason will be already set to the reason of the first abort signal that was already aborted.
  • Asynchronously aborted, when any abort signal in iterable aborts. The reason will be set to the reason of the first abort signal that is aborted.


Using AbortSignal.any()

This example demonstrates combining both a signal from an AbortController, and a timeout signal from AbortSignal.timeout.

const cancelDownloadButton = document.getElementById("cancelDownloadButton");

const userCancelController = new AbortController();

cancelDownloadButton.addEventListener("click", () => {

// Timeout after 5 minutes
const timeoutSignal = AbortSignal.timeout(1_000 * 60 * 5);

// This signal will abort when either the user clicks the cancel button or 5 minutes is up
// whichever is sooner
const combinedSignal = AbortSignal.any([

try {
  const res = await fetch(someUrlToDownload, {
    // Stop the fetch when any of the signals aborts
    signal: combinedSignal,
  const body = await res.blob();
  // Do something with downloaded content:
  // ...
} catch (e) {
  if (e.name === "AbortError") {
    // Cancelled by the user
  } else if (e.name === "TimeoutError") {
    // Show user that download timed out
  } else {
    // Other error, e.g. network error
