Thank you. Really appreciate your response on this.

As of now, it’s not clear on whether we need npm server along with AEM however we can generate the required java scripts using Angular CLI and add them as part of Client Library. 

Thank you for the details..

Is there any best practices defined by Adobe to add Angularjs 2 framework to AEM 6.1 or higher?

Thank you

Do we have Jenkins Plugins to trigger AEM UI Test Suites as part of Continuous Integration. Please share your inputs in case we have any such plugins for Jenkins or is there any alternative we have to trigger AEM UI Test cases outside AEM Author.
