Add natural stop() effect

[laresbernardo]

Thanks for building this really nice add-on. I'm adding it so that it gets triggered once the user marks as finished a whole process of a shiny app I'm working on. Nice (hidden) touch!

Sharing the code as an additional use-case where the fireworks are triggered for 5 seconds and then stop. In case you'd like me to add it to the README, let me know.

In UI

checkboxInput("final_model", "Report as final model", FALSE)

In server

  fw <- fireworks::Fireworks$new()
  observeEvent(input$final_model, {
    fw$stop()
    if (isTRUE(input$final_model)) {
      fw$start()
      Sys.sleep(5)
      fw$stop()
    }
  })

Finally, regarding the "special effects", is there a way to set stop() to stop "launching fireworks" instead of simply getting rid of all at the same time to have a more natural stopping effect?

Thanks for raising this @laresbernardo .

I can leverage updateOptions to add an "fade out" effect. It can then be provided as an argument to stop(), like so:

fw <- Fireworks$new()
fw$start()
Sys.sleep(5)
fw$stop(fadeOut = TRUE)
