AggregatedAbortController

A extendable AbortController with link aggregation with existing AbortController or AbortSignal.

Install

npm install aggregated-abortcontroller

Usage

import AggregatedAbortController from 'aggregated-abortcontroller';

// Create a new AbortController
const controller = new AbortController();

// Create a new AggregatedAbortController that aggregates the signal of the AbortController
const aggregatedController = new AggregatedAbortController([controller.signal]);

// Register a listener to the aggregated signal
aggregatedController.signal.addEventListener('abort', () => {
  console.log('aborted');
});

// Calling abort on the linked signal will also abort the aggregated signal
controller.abort(); // => 'aborted'

// But calling abort on the aggregated signal will not abort the linked signal
aggregatedController.abort();
