These are the steps to follow to use FontAwesome icons with React + Vite.js:

1.Install the dependencies:

Run the following commands to install the necessary FontAwesome packages:

npm install --save @fortawesome/fontawesome-svg-core npm install --save @fortawesome/free-solid-svg-icons npm install --save @fortawesome/react-fontawesome

2.Import the FontAwesomeIcon component:

In your React component, import the FontAwesomeIcon like this:

import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';

3. Import the icons you want to use:

When importing icons, you need to write the icon's name in camelCase (starting with a lowercase letter and capitalizing subsequent words). You should also use the exact name of the icon as it’s defined in the FontAwesome library.

For example, if you want to use the arrow-right icon, the original name on FontAwesome is "fa-arrow-right". When you import it into your React component, you will use camelCase like this:

"import { faArrowRight } from '@fortawesome/free-solid-svg-icons';"

Note: The name faArrowRight corresponds to the FontAwesome icon "fa-arrow-right". When working with FontAwesome in React, the icon names are converted from the original format (with dashes) into camelCase.

Also, remember to import icons from the correct package: in this case, we're using the @fortawesome/free-solid-svg-icons package for the solid icons. If you're using a different set (like regular or brands), make sure to import from the corresponding package.

4.Finally, use the FontAwesomeIcon component in your JSX like this:
