Progress Indicator for Event reactive without loops

shiny
1

I want to create progress Indicators in my shiny app. I have gone through Official Documentation it is of no use to me because i don't have any loops in my code. how to implement Progress indicator in event reactive without any loops

I like the withSpinner function in shinycssloaders (https://www.rdocumentation.org/packages/shinycssloaders) for showing when things that take awhile are calculating.

It won't show % progress (in my case i dont even know how Shiny would calculate that), but implementation is incredibly simple and wont complicate your app's code much (example below)

# in global.R
library(shinycssloaders)

# in ui.R
withSpinner(plotOutput("some_reactive_plot_that_takes_time_to_generate_based on an eventReactive object"))

withProgress() combined with incProgress() should allow you to display progress bar in the shiny app.
