native-abort-controller

Returns native AbortController/AbortSignal if available or the abort-controller module if not

An (almost) drop-in replacement for the abort-controller module that returns the native AbortController if available or the polyfill if not.

Why?

Some environments such as the Electron Renderer process straddle the node/browser divide with features from both APIs available. In these cases the webpack approach of always using the browser field in your package.json to override requires is too heavy-handed as sometimes you want to use the node version of an API.

Instead we can check for the availability of a given API and return it, rather than the node-polyfill for that API.

This module may become unecessary if mysticatea/abort-controller#24 is resolved.

Install

You must install a version of abort-controller alongside this module to be used if a native implementation is not available.

$ npm install --save native-abort-controller abort-controller

Usage

import { AbortController } from 'native-abort-controller'

const controller = new AbortController()
const signal = controller.signal

signal.addEventListener('abort', () => {
    console.log('aborted!')
})

controller.abort()
