Connecting to oracle data visualisation cloud service with node js

Question

I’m looking to integrate reports/charts from oracle data visualisation cloud service to my web application which is using node js for backend and angular for front end. I have a dev server in oracle cloud with the reports and charts ready. How can I get started to use the api from oracle cloud using node js . Is there any modules that support this ? Or can any one guide me on how to establish the connection and authenticate it. Can anyone share related documents as well. Thanks in advance
