useWorker() – Use Web Workers with React Hooks

useWorker() is a js library (with typescript support) that allows you to use the Web Worker Web API, through React Hooks. This library allows you to run the expensive function without blocking the user interface, using a simple syntax that makes use of Promise

import React from "react";
import { useWorker, WORKER_STATUS } from "@koale/useworker";

const numbers = [...Array(5000000)].map(e => ~~(Math.random() * 1000000));
const sortNumbers = nums => nums.sort();

const Example = () => {
  const [sortWorker, { status, kill }] = useWorker(sortNumbers);
  const runSort = async () => {
    const result = await sortWorker(numbers); // non-blocking UI
    console.log("End.");
  };
  return (<button type="button" onClick={runSort}> Run Sort</button>);
};

Installation per NPM/Yarn:

npm install --save @koale/useworker
