How to make a PWA application with Reactjs?

To create a PWA application with React, here are some basic steps that you should follow:

1. Set Up Your React App:

To create a new React application, you will need to have Node.js and npm installed on your machine. You can create a new app using `create-react-app` by running this command in your terminal: \`\`\` npx create-react-app my-pwa \`\`\` This will create a new directory called `my-pwa` with a barebones React application.

1. Turn Your React App into a PWA:

After the application is created, navigate to the `public` directory \`\`\` cd my-pwa/public \`\`\` Here, you will need to create a manifest.json file which will define how your app appears to the user. \`\`\`json { “short\_name”: “React App”, “name”: “Create React App Sample”, “icons”: [ { “src”: “favicon.ico”, “sizes”: “64×64 32×32 24×24 16×16”, “type”: “image/x-icon“ }, { “src”: “logo192.png”, “type”: “image/png”, “sizes”: “192×192“ }, { “src”: “logo512.png”, “type”: “image/png”, “sizes”: “512×512“ } ], “start\_url”: “.”, “display”: “standalone”, “theme\_color”: “#000000”, “background\_color”: “#ffffff“ } \`\`\` Then, in index.html add \`\`\` \`\`\`

1. Register Service Worker:

Create-react-app already comes bundled with a service worker, which is a script that your browser runs in the background, separate from a web page. Navigate to the src directory and replace the code in `index.js` to register the service worker: \`\`\`javascript import React from ‘react’; import ReactDOM from ‘react-dom’; import ‘./index.css’; import App from ‘./App’; import \* as serviceWorker from ‘./serviceWorker’; ReactDOM.render( , document.getElementById(‘root’) ); // 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://bit.ly/CRA-PWA serviceWorker.register(); \`\`\`

1. Test Your PWA:

You can test your PWA by running `npm start` and opening the app in Chrome. Open Developer Tools and go to Application > Service Workers. You should see your service worker running.

1. Deployment:

Finally, when you’re ready to deploy your PWA, you can run `npm run build` to create a production build of your React app. This will create a `build` directory with a static version of your application, which can be deployed to any static file server.

Remember to always review your application with the Lighthouse tool in the Chrome devtools, that way you can maintain the highest standards in terms of PWA.
