I create a ReactJS project with the create-react-app package and that worked well, but I cannot find webpack files and configurations.
How does react-create-app work with webpack? Where are the webpack configuration files located in a default installation with create-react-app? I'm unable to find configuration files in my project's folders.
I have not created an override config file. I can manage config settings with other articles but I want to find the conventional config file(s).
