mergeSignals(...signals)

Returns an AbortSignal that aborts when any of the input is aborted. Ideal when:

• you want to add a timeout signal
• you receive a signal and want to have your own internal abort controller.

import {mergeSignals} from 'abort-utils';

// First signal
const userAction = new AbortController();
cancelButton.addEventListener('click', () => {
	userAction.abort('User cancelled');
});

// Second signal
const timeout = AbortSignal.timeout(100);

// Merged signal
const mergedSignal = mergeSignals(timeout, userAction.signal);
mergedSignal.addEventListener('abort', () => {
	console.log('One of the signals was aborted', mergedSignal.reason);
});

Type: AbortSignal, AbortController
