Quick Start

• Zero Dependencies, Lightweight - Pure React hooks with no external dependencies
• Function-like API - Use Web Workers just like calling regular functions
• Automatic Cleanup - Workers are automatically terminated when components unmount

npm install @atom-universe/use-web-worker

Basic Usage

import { useWebWorkerFn } from '@atom-universe/use-web-worker';

function App() {
  const [workerFn, status] = useWebWorkerFn((a: number, b: number) => a + b);

  const handleClick = async () => {
    const result = await workerFn(1, 2);
    console.log(result); // 3
  };

  return (
    <div>
      <button onClick={handleClick}>Calculate</button>
      <div>Current status: {status}</div>
    </div>
  );
}
