Oh my days, how did I miss this comment. This might not be of use but for someone else. So depending on the size of the application, you can have a different database where you can log your errors and also you can try some premium sources like BugSnag and the likes. I'm currently writing an article on how to use BugSnag to report your errors and how to get them resolved.

I always find it difficult to use JS Docs but I'll try it out asap. Thank you.
