An implementation of WHATWG AbortController interface.

})

controller.abort()
`

💿 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

$3

`js
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.

$3

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

`js
import "abort-controller/polyfill"
// or
require("abort-controller/polyfill")
`
