I would like to know if there is a way to add, in the R console, a percentage progression of my shiny application loading.
I don't use URL, run my app in R Studio and my shiny app is more than 1 minute to compute ("big data"), so i would like to add a percentage progression in the R console in R Studio (or in the window that shiny generates).
It's not possible to show a progress bar on app loading, but if you delay reading the data until the server function runs, you can show a progress bar there.
