Laravel Mix Fontawesome

I installed Fontawesome 5 using

npm i --save @fortawesome/fontawesome-free

Edited my app.scss by adding:

@import '~@fortawesome/fontawesome-free/css/all.css';

Using Laravel 5.7. The icons works when I access using php artisan serve (http://127.0.0.1:8000/) but when direct access through xampp (localhost/project/public), it shows as square. Do you have any idea? thank you.
