Custom Javascript in UI Without Custom Build
I have some custom Javascript, used for application monitoring, that I'd like to put in the UI. I know how to do this if I'm willing to run a custom build of NiFi. Is there anyway to do this without a custom build of NiFi?
My first thought was creating a dummy processor with an Advanced UI, and seeing if maybe I could get Javascript for that Advanced UI to run when the NiFi UI is loaded. This is a bit of work, so I thought I'd ask before trying this.
My second thought was to try and abuse the nifi.ui.banner.text setting, but this uses `text()` to set the banner text, so would not work for a block of Javascript.
I ran across this article by Scott Aslan, https://community.hortonworks.com/articles/134888/an-apache-nifi-frontend-developers-cookbook-part-1.html, but it was focused on core NiFi UI (great read, just not the direction I'm trying to go).
Thanks,
Peter

Joe,
We are testing out a product called AppDynamics for application monitoring/user experience tracking. We've hooked it into NiFi as an javaagent, but it also has an option where you can inject some JavaScript into the frontend and monitor UX there.
Doesn't really feel like something that NiFi needs to support, unless there was going to be a generic function to add .js files to make them globally accessible, like we do with jar's in the lib folder.

Peter,
I'm not aware of any plans to provide/support what you're suggesting at this point.
Can you describe more what you mean and would be doing with this? Is what you are trying to do something that the UI should just enable?
Thanks

Peter,
I'm not aware of any plans to provide/support what you're suggesting at
this point.
Can you describe more what you mean and would be doing with this? Is what
you are trying to do something that the UI should just enable?
Thanks
