Hosting GraphQL API from GRANDstack starter

I used the GRANDstack starter to make a website. Now I am trying to host it. I was able to host the Neo4j on GCP. However, I am having trouble with the GraphQL API. I notice there is no script for production only test, start and seedDB. I never used a sever before and do not know how to write the script for production.
Can someone help me?
