It's just an example to show what type of code `reactpack` builds, ES6 and JSX with style loading in this case. If you want a more minimal React-like build you can switch out React with lightweight alternatives like Preact or React-lite.

For reference, I build a standalone datepicker module with preact + redux at under 20kb (min + gz)... worked out really well. By comparison, went with regular react recently, and the payload quickly got over 200kb, though I needed a couple relatively heavy libraries for the app in question.

Another point worth mentioning is using react-icons individually (svg based), same for component libraries where you are only using a few components... tends to work out much lighter. Also, if you do use bootstrap as a base css library, work from the source instead of monkey patching the .css output.
