Grafana-Loki is a nice logging service and I want to deploy it for an app on Heroku. I've looked around and there doesn't seem to be too much information about this. I found this twitter thread which references this python repository, but I don't totally understand what's going on. I'm running a small javascript app on heroku, and I want the logs to go to grafana cloud. How do I apply this python code to my situation? I'm not that technical so I get lost easily when applying something to my own situation.
