How to separate react module from main application?

Question

npm

There is a task to separate part of the application in the form of a module.
A module contains components, reducers, css (via postcss and react-css-module), etc.
Is there a way to do this outside of npm package?
And then it brings pain (any change in the module - recompile it again and restart the assembly of the main application, no automatic assembly)

А чем штатный js экспорт-импорт не устраивает?
//some_module.js
......
export {почтилюбойобъект}
//main_app.js
import {почтилюбойобъект} from './some_module.js'
