Is there a global busy indicator for R shiny/dashboard applications. I do not want to set an indicator to each chunk everytime like the example given below: https://mastering-shiny.org/action-feedback.html?q=progr#progress-bars

But I am looking for something that I want to set once and it will simple indicate busy notifications whenever shiny server is making a somewhat long calculations (10/30 seconds).

I think this should be a default behaviour of shiny but I could not see anywhere something like this.

I saw this library but did not work: https://cran.r-project.org/web/packages/shinybusy/vignettes/shinybusy-usage.html

  • A nice solution for the users is to use non blocking techniques like future/promise, [here is an example](https://cran.r-project.org/web/packages/promises/vignettes/shiny.html) – HubertL Apr 15 '21 at 18:22
  • My current runs are only around 10/30 seconds. I think I should update the question. – entropy Apr 15 '21 at 18:34
  • I found this solutions looks doing what I want but not that elegant. Untill I find a better solution, I may use this one https://colinfay.me/watch-r-shiny/ – entropy Apr 15 '21 at 18:57
