Unfortunately it takes a lot of work to get a React app with a Node backend up and running,
This is a barebones boilerplate for starting an Express, React, and Node app. It also includes React Router Dom. It does not include any paricular database or ORM/ODM.
To get this boilerplate up and running run yarn install in the root directorary to install all dependencies.
To start the app run yarn start from the root directory, you should now see "Hello World" at http://localhost/3000.
It's worth noteing that in this Hello World example the "Hello World" being display is actually coming from an API call to the backend; I realize this is completely uncessary but it helps create a more complete template for starting your porject.
