Laravel-mix mandatory to use ReactJS ?

Hello everyone and thank you in advance for your help.

I have a Laravel 7 project that I will have to integrate ReactJS into.

In fact, in order for my project to display correctly, I have to disable laravel-mix, otherwise the CSS is not loaded (as the console shows you).

In order to work around this issue, I had to disable laravel-mix (/Applications/MAMP/htdocs/overlap_github/myproject/webpack.mix.js) by setting it to false like this:

My question :

Is Laravel-Mix important for me to be able to use ReactJS?

Because I will have to integrate a ReactJS component.

Thank you in advance for your help.
