Therefore you need to go to the src folder and delete Logo.svg, App.css, index.css, and App.test.js files. And create the following folders inside the src folder named components, assets, helpers, and utils, then move your serviceWorker.js into the helper’s folder. App.js file into the Components folder.
Now open the index.js file and delete the following snippet in index.js file.
Then modify the App.js and serviceWorker.js files paths in index.js import like following.
import App from ‘./components/App’;
import * as serviceWorker from ‘./helpers/serviceWorker’;
Go to the Components folder and open the App.js. Delete the return part of the App function. Now your file organization will be like below.
