Actually, I'm just curious as to why webpack is used in react applications. Why do I still use Webpack to create a dist folder with a dist.js file if I can create a build using npm run build?
Can somebody help me with my confusion?

I wanted to deploy a react project. I used the npm run build command to create a build folder for deployment. Somehow, i dont know where the output ont this build folder is. Can someone explain to me, how i should proceed?
npm run build or yarn build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed.
I've a react app created using create-react-app. I recently saw some article saying to add few loaders to webpack config file. But I've no idea where to find the webpack.config.js file inside a react project.
Really appreciate any ideas or suggestions.
Webpack config is not available in CRA. If you want to get one, you have to do an eject (https://create-react-app.dev/docs/available-scripts/), but if you don't need to make eject, or you don't wanna do this, you can use the library which is the wrapper of CRA, for example: CRACO or rewrite
I have executed this command npm run eject and I got several new files appeared in my React project but I don't see these two files, "webpack.config.dev.js" and "webpack.config.prod.js" .
What is wrong in my project?
Nothing is wrong with your project, Its just the way create-react-app works
You wont see webpack.config.dev.js and webpack.config.prod.js because those are not embedded in react-scripts, instead you will find the webpack configuration in config/webpack.config.js
When you run npm run eject
that script will move all the webpack & webpackDevServer configuration from react-scripts to the App Root giving you all the webpack configuration and related files and scripts
I'm trying to use the create-react-app in an existing app without using the default index.html built in that links the scripts generated by running yarn start. These files include /static/js/bundle.js, static/js/0.chunk.js, static/js/main.chunk.js, and /main.somehash...hot-update.js
I set INLINE_RUNTIME_CHUNK=false in my .env but no files ever get generated in the static folder when running yarn start.
You can either eject your project or use react-app-rewired to customize your webpack configuration. This way, you can modify the path to output js.
How do i can copy webpack files to work in a project?
The folders contain JS modules (scripts) with comments.
Thanks.
If you are using react js with cli means(create-react-app) than you no need to copy webpack. Just use npm eject
if you are using CDN than try this one
I assume you are using create-react-app(CRA).
as far as i know you must eject from CRA to access webpack config in your project use either npm eject or yarn eject.
This way you can't use migration script to upgrade your CRA any more.
Also you could use React-app-rewired without ejecting.
