abort-controller

npm version Downloads/month Build Status Coverage Status Dependency Status

An implementation of WHATWG AbortController interface.

Create val
import AbortController from "abort-controller" const controller = new AbortController() const signal = controller.signal signal.addEventListener("abort", () => { console.log("aborted!") }) controller.abort()

https://jsfiddle.net/1r2994qp/1/

💿 Installation

Use npm to install then use a bundler.

npm install abort-controller

Or download from dist directory.

  • dist/abort-controller.mjs ... ES modules version.
  • dist/abort-controller.js ... Common JS version.
  • dist/abort-controller.umd.js ... UMD (Universal Module Definition) version. This is transpiled by Babel for IE 11.

📖 Usage

Basic

Create val
import AbortController from "abort-controller" // or const AbortController = require("abort-controller") // or UMD version defines a global variable: const AbortController = window.AbortControllerShim

If your bundler recognizes browser field of package.json, the imported AbortController is the native one and it doesn't contain shim (even if the native implementation was nothing). If you wanted to polyfill AbortController for IE, use abort-controller/polyfill.

Polyfilling

Importing abort-controller/polyfill assigns the AbortController shim to the AbortController global variable if the native implementation was nothing.

Create val
import "abort-controller/polyfill" // or require("abort-controller/polyfill")

API

AbortController

https://dom.spec.whatwg.org/#interface-abortcontroller

controller.signal

The AbortSignal object which is associated to this controller.

controller.abort()

Notify abort event to listeners that the signal has.
