docker - Communication from Pod to Pod on same node inside kubernetes in GCP

Question

I have dockerized and created deployment and service for both front(REACT) and backend (EXPRESS NODE JS) project in kubernetes. I have successfully deployed in Kubernetes(Single node cluster) in Same Node with Two Pods(i.e One Pod --> REACT APP and SECOND POD --> EXPRESS NODE JS) in Google cloud Platform.

Question:

1.) How to communicate from one pod to another pod inside the Node in Kubernetes cluster?

2.) I have exposed my REACT app to the Outer world by creating LoadBalancer Type Service in kubernetes and i am able to access the React App Endpoint from the Browser. Now, Is it possible to access EXPRESS app from REACT app inside the node without exposing my EXPRESS app to outer world. How to achieve this?

Thanks in Advance.
