Hi Dirk, You're definitely not the odd one out there using JS with NiFi. The most common usage is definitely Groovy but I'm aware of NiFi users using JS. I'm not aware of a specific timeline as I don't know if someone in the community is actively looking into it right now but I agree that this should be something to take into account for NiFi 2.0.
