Backend service APIs are implemented in NodeJS using NestJS framework.

All APIs are protected with an id token sent from the frontend. Integrity and authenticity of the token is verified in the backend and the users uid is retrieved.

Backend NodeJS service is running in Google Kubernetes. Database is accessed via Cloud SQL proxy which is running in Google Kubernetes as a sideloaded Docker image.

All communications from NodeJS backend service to database are authorized, encrypted and secured
