I recently started using Heroku for my deployments. So far I only used it to deploy front-end react apps which were fairly straight forward. But now I am trying to deploy a full-stack react app that uses a JSON-server as the backend. During the development process, I used concurrently to run the JSON server and the react app at the same time. I am not really sure how to create a static build for it and deploy it on Heroku as a single instance since the JSON server and react-app are two separate processes. Any help here will be highly appreciated. Thank you.
