For example, I could simply add a print statement at the beginning of my reactive of interest to find out each time what triggered it?
reactive_example <— reactive({ print(last_trigger()) _#Rest of reactive logic..._ )}
Same question on stackoverflow... and the github discussion where this exact feature is asked for by shinyjs author @daattali and @jcheng seems interested..
I don't think this exists. The github issue is probably the best way to track this. If it does get implemented, I'm 99% sure the github issue will get updated
This is pretty much a hack, but achieves this without requiring any changes to Shiny.
Check out my last comment on the GitHub issue for a quick write-up, and an example of another method you might be able to use. https://github.com/rstudio/shiny/issues/1846#issuecomment-361831280
