cpAxios is a simple axios wrapper that provides an advanced cancellation api.
This library supports three types of the cancellation API that could be used simultaneously:
- Axios cancelableToken
- AbortController signal
- CPromise promise cancellation API
In addition, since cpAxios return a custom promise instead of the native, you get some powers of CPromise:
- concurrency limiting fot creating request queues
- progress capturing
- promise timeouts
Starting from version 0.1.12 the package imports peer dependencies instead of built-in.
So, you should install c-promise2 and axios packages manually using the following command:
$ npm install cp-axios$ yarn add cp-axiosBrowser UMD bundle (with all dependencies inside):
- production UMD bundle (or minified ~45KB)

// yeah, we able to cancel the entire task and abort pending network requests
//setTimeout(() => promise.cancel(), 4500);cpAxios can be easily used with React using the useAsyncEffect hook, which allows cancelable asynchronous functions to be executed as effects (Live Demo):
import React from "react";
import { useAsyncEffect } from "use-async-effect2";
import cpAxios from "cp-axios";
/*
Note: the related network request will also be aborted
Check out your network console
*/
function TestComponent({ url, timeout }) {
const [cancel, done, result, err] = useAsyncEffect(
function* () {
return (yield cpAxios(url).timeout(timeout)).data;
},
{ states: true, deps: [url] }
);
return (
<div>
{done ? (err ? err.toString() : JSON.stringify(result)) : "loading..."}
<button onClick={cancel} disabled={done}>
Cancel async effect (abort request)
</button>
</div>
);
}
export default TestComponent;The request will be automatically aborted when the effect is canceled / restarted.
The package exports a wrapped version of the axios instance. See the axios documentation to get more information.
