Navigate to the new folder created

Start the application on a different port (e.g., 3002) to avoid conflicts:

Step 2: Setting Up React Query

React Query is a powerful tool for fetching and caching server-state in your React application. To integrate React Query, follow these steps:

1. Install React Query
2. Update the index.js file to include the React Query provider

Step 3: Creating a Functional Component for Fetching Data

1. Create a new file Companies.js

2. Ensure the API URL is correct

   • Update the fetchCompanies function with your actual API endpoint if needed.

Step 4: Integrating the Component

Update your main app file (e.g., App.js)

Step 5: Adding Some Basic CSS

1. Add the following styles to App.css
2. Make sure to import the App.css in App.js

With these steps, your application should now be set up to fetch and display a list of companies, and you have some basic CSS for styling.
