How to Deploy React App with node backend on Production?

Hi ,

I am having react app with node backend.I had successfully deployed react app on digital ocean using the tutorial.

“https://coderrocketfuel.com/article/deploy-a-create-react-app-website-to-digitalocean#option-2-install-the-key-manually”

but it is not able to use backend.

I am getting “.500 Internal Server Error” For node, i had used tutorial below for server setting.
