Using the example of one of the manuals, I created a procurement for React + Redux - https://github.com/keslo/React-Redux-environment
Downloading. Install packages via npm install launch the project via npm start Everything works.
But!
The assembly file in the project folder does not appear. Although at the address after running localhost:3000/static/bundle.js build is present. But there is no location directory and file in the project folder.
What am I doing wrong?
