React Service Worker Helper

A pure react component for managing service worker life cycle. This project is inspired by the project @medipass/react-service-worker published by @medipass (it is currently inactive for 4 years now). Tailored to our needs, and hopefully for you too, here are the differences from the original one:

• we have updated the code to use the functional component of react.
• the service worker is registered by default if you are building the reactjs app for production.
• we have disabled the option to unregister the service worker.

Installation

npm i @sws2apps/react-sw-helper

Usage

Basic implementation

Import the <ServiceWorkerWrapper> component and wrap it around your application.

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import ServiceWorkerWrapper from '@sws2apps/react-sw-helper';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
     <ServiceWorkerWrapper publicServiceWorkerDest='/service-worker.js'>
        <App />
     </ServiceWorkerWrapper>
  </React.StrictMode>
);

Advanced implementation

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import ServiceWorkerWrapper from '@sws2apps/react-sw-helper';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <ServiceWorkerWrapper
       onError={(err) => console.log(`An error occured: ${err}`)}
       onInstalled={() => console.log('Service worker installed')}
       onUpdated={() => console.log('Service worker updated')}
       onWaiting={() => console.log('Service worker waiting')}
       publicServiceWorkerDest='/service-worker.js'
    >
       {({ update }) => <App updatePwa={update} />}
    </ServiceWorkerWrapper>
  </React.StrictMode>
);
