abort-utils

Utility functions to use and combine AbortSignal and AbortController with Promises

Install

npm install abort-utils

import {
	onAbort,
	mergeSignals,
	linkControllers,
	promiseFromSignal,
	ReusableAbortController
} from 'abort-utils';

This package exports various utilities, just import what you need.

onAbort: Add multiple callbacks, observers and other abort controllers to a single signal.
mergeSignals: Create a new signal that aborts when any of the input signals aborts.
linkControllers: Link multiple controllers so that when one aborts, they all abort with the same reason.
signalFromEvent: Create an AbortSignal that is aborted when an event is dispatched.
signalFromPromise: Create an AbortSignal that is aborted when a Promise is resolved or rejected.
promiseFromSignal: Create a Promise that resolves or rejects when the signal aborts.
ReusableAbortController: Like AbortController, but it generates a new signal after it's aborted.

Here's a visual representation that might help understand how some of the methods differ and behave.
