Hmm, a quick search for react admin shows quite a few results:

• http://rubix.sketchpixy.com/app/dashboard
• http://gridgum.com/theme-preview/reactive-admin/
• http://ani-react.strapui.com/#/dashboard/home
• http://start-react.github.io/sb-admin-react/#/home

Now there is one in reactjs and bootstrap 4 and it uses create-react-app cli. Link here:
