Viewswhere is create-react-app webpack config and files?
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).

If you want to find webpack files and configurations go to your package.json file and look for scripts
You will find that scripts object is using a library react-scripts
Now go to node_modules and look for react-scripts folder react-script-in-node-modules
This react-scripts/scripts and react-scripts/config folder contains all the webpack configurations.

The files are located in your node_modules/react-scripts folder:
Webpack config:
Start Script:
https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/scripts/start.js
Build Script:
https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/scripts/build.js
Test Script:
https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/scripts/test.js
and so on ...
Now, the purpose of CRA is not to worry about these.
From the documentation:
You don’t need to install or configure tools like Webpack or Babel. They are preconfigured and hidden so that you can focus on the code.
If you want to have access to the config files, you need to eject by running:
npm run eject
Note: this is a one-way operation. Once you eject, you can’t go back!
In most scenarios, it is best not to eject and try to find a way to make it work for you in another way.
If you need to override some of the config options, you can have a look at https://github.com/gsoft-inc/craco

A lot of people come to this page with the goal of finding the webpack config and files in order to add their own configuration to them. Another way to achieve this without running npm run eject is to use react-app-rewired. This allows you to overwrite your webpack config file without ejecting.
