index.tsx file with update mechanism for the service worker

index.tsx

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import {Config} from "./serviceWorker";

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

const config: Config = {
    onUpdate: (registration) => {
        if (registration && registration.waiting) {
            registration.waiting.postMessage({ type: 'SKIP_WAITING' });
            window.location.reload();
        }
    },
};

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.

serviceWorker.register(config);
