Hi experts,

Based on SAP CAP documentation in this link: 

https://cap.cloud.sap/docs/guides/using-services#mashing-up-with-remote-services

It seems to handle expands in Java we must take care of
request in our handler like in example:
https://github.com/SAP-samples/cloud-cap-risk-management/blob/ext-service-s4hc-suppliers-ui-java/srv...

But when we use this use case in nodejs, there is no
need to handle expands. It is handled by CAP libraries.
We just need to bind to Suppliers read event and send
the incoming CQN query to remote service and it is
done.


But in this way we need to also take care of nested
relations and there will be many boilerplate code. Is
there a library to handle CQN queries like in nodejs ?
