Progressive Web App Development using React.js: A comprehensive guide

Creating a React Component Firstly, let's create a Counter component. Here, it is located in a components folder and given the name Counter.js. To simplify the process, copy and paste the following code into the required files. In this example, it is built as a simple page.   import React, { useState } from "react"; const Counter = () => { let [count, setCount] = useState(0); const increment = () => { setCount(count + 1); }; const decrement = () => { setCount(count - 1); }; return (   Counter App +{count} - ); }; export default Counter; By typing "npm start" at the command prompt, you can launch your application to a chosen localhost URL. You can now begin to assess your prior efforts.

Enter the command:   npm start   This launches the program at the specified localhost URL. Visit the URL to examine the application once the dev server is active and live on the command prompt. You need to see something like this: Figure 2 React Counter App   Running Progressive Web Application Returning to the index.js file change the following:   // If you want your app to work offline and load faster, you can change // unregister() to register() below. Note this comes with some pitfalls. // Learn more about service workers: https://cra.link/PWA serviceWorkerRegistration.register(); //change the service worker registration from 'unregistered' to 'registered'   You can basically use the app even while it's offline by changing the service worker from unregistered to registered, which is a significant advantage of PWAs. You can learn more about this here. Once you've configured the PWA files, you can use the "serve" package to deploy your application to a static server and test it by serving it to localhost. Now, install the service package, rebuild the application, and deploy the application using serve to ensure that you have it:   npm install serve npm run build serve -s build //if you encounter an error with this command, try 'npx serve -s build'   When you run the serve command, the following message should appear, indicating that your application has been deployed to http://localhost:3000. Also, the URL is automatically copied to your clipboard for convenient pasting in your browser. Figure 3 Successful Compiling Message You should see something like this if you type the localhost URL into your browser: Figure 4 PWA Counter App  

PWA Features- Now that the PWA React application is operational, let's open the Developer Tools to check inside (for Google Chrome, entering F12 opens the Dev Tools). You should be able to see your service worker from index.js running in the Application tab after registering it. On the left side of the tab should be a section for service workers. You can view for http://localhost:3000 from here. You currently have a Service Worker that is active and running from your service-worker.js file.

Figure 5 Manifest For PWA App That's it; you've successfully built your first PWA React application! Many PWA features, including installation, offline browsing, and Lighthouse audit testing, can be tested from this point. Conclusion PWAs deliver native-like experiences and increased engagement through features such as home screen additions, push notifications, and many others that do not require installation. When built using React.js, these apps have the potential to provide a fantastic user experience with fantastic interaction. React.js is a prominent platform that competes with top-tier UI frameworks and considerably simplifies web app development. This article has walked you through the process of building a progressive web application using React.js. We also learned about the relevance of PWA in the business.
