React hook for imperative async operations.
Source code is hosted on GitHub
yarn add @corets/use-action
npm install --save @corets/use-action
This library is built on top of this package:


Takes a function or an instance of Async and turns it into an observable async operation that can be triggered manually any time in the future.
import React, { useState } from "react"
import { Async } from "@corets/async"
import { useAction } from "@corets/use-action"
const sharedAction = new Async(async (argument: number) => `Global value is ${argument}`)
const Example = () => {
const action = useAction(async (argument: number) => `Value is ${argument}`)
const globalAction = useAction(sharedAction)
const handleRun = () =>
const handleCancel = () => action.cancel()
if (action.isRunning()) {
return <h1>Executing action...</h1>
if (action.isErrored()) {
return <h1>There was an error :(</h1>
if (action.isCancelled()) {
return <h1>Action has been cancelled</h1>
return (
Result: {action.getResult()}
<button onClick={handleRun}>Run</button>
<button onClick={handleCancel}>Cancel</button>
