Re: How to launch a Helium Application in local deploy mode
Hi Lee,
Thank you for your reply. Actually I already tried dev mode and succeeded.
My question is how to launch Helium application not in development mode but
in deploy mode like 'SPELL' described in
https://zeppelin.apache.org/docs/snapshot/development/writingzeppelinspell.html#1-enabling.
Could you please kindly guide more? Thanks!

Re: How to bind angular object with backend when write Helium Application
Hi Lee, Follow your instruction, I can update frontend from beckend and get AngularObject through 'HeliumAppAngularObjectRegistry'. However, I don't know how to get 'InterpreterContext' in Helium Application, which is needed to initialize an 'AngularObjectWatcher' when adding watcher. I checked ApplicationContext but seems I cannot get InterpreterContext there. Could you share more lights on that?

How to bind angular object with backend when write Helium Application
Hi Group, Recently we are exploring building data analysis application based on Zeppelin. We checked Helium document and think it could be an appropriate way to customize both frontend and backend in Zeppelin. However, we did not find a way to bind angular object with backend data when extends Application. More detail, we want to catch the frontend angular object value / change event in the backend and then process in some way to feedback to frontend. Could someone kindly show us the right way to do this? We are now using 0.8.0 snapshot code. Thank you very much in advance! Best, Fishfish
