How to make react and rails app automatically

It is so easy, but I didn’t know and it is forgettable, so I’m going to take a note. Database is postgresql. Ruby version is 2.5 and Rails version is 5.2.

Create folders

rails new app_name --webpack=react --database=postgresql

reactjs/react-rails

and this.

Start react and rails

bin/webpack-dev-server

and

rails s

piece of cake!!
