My aplplication is in Angular 2+, NestJs (Node) and PostgreSQL.

With this setup, the recommended camunda deployment would be using standalone remote server (Camunda BPM Run), so that you can communicate to camunda services via REST api from NestJs (Node). You can use Postgres as datastore for camunda.

@Niall had made nice video tutorial on how to setup camunda bpm run:

Camunda BPM and Existing External Application

Then you can install the camunda as standalone server . And process engine services can be accessed via REST API, so the client application can be of any technology.
