How to setup webpack+yarn+react?

Question

React

Hello.
A bit of a noob question, but still.
There is an application on React + Redux.
package manager - yarn.
First I used npm. The build was compiled as: npm run build.
I didn't use WebPack, but when uploading the application, I noticed that the build size is about 1mb, which is quite a lot. I read articles where it is indicated that with the help of WebPack, you can compress the final build to several hundred kb.
Can anyone describe how to do this? How to connect webpack and compress the final build?
Thank you in advance.

Answer 1

create-react-app
though the final file is still not small and a few hundred kilobytes are close to 500, but it also depends on the project ...
