ReusableAbortController

This class is like AbortController, but it can be reused after it's aborted. The previous signal is aborted and discarded, and a new one takes its place.

import {ReusableAbortController} from 'abort-utils';

const controller = new ReusableAbortController();
const firstSignal = controller.signal;

fetch('/api/ping', {
	signal: firstSignal
});

// The fetch request will be cancelled
controller.abortAndReset();
console.log(firstSignal.aborted)
// ^ true


// This will get a new signal, that is not aborted
const secondSignal = controller.signal;
console.log(secondSignal.aborted)
// ^ false

fetch('/api/ping', {
	signal: secondSignal
});

.abortAndReset(reason?: any)

Just like AbortController.abort, it takes an optional reason argument. After the signal is aborted, a new one is created and takes its place.

.signal

The signal that is currently active. It's a AbortSignal instance. It will be recreated after .abortAndReset is called. Existing references to the previous signal will stay aborted.

Note that accessing controller.signal.aborted directly will always be false. The property changes only in previously-extracted signals.
