Bar / Percentage progression during shiny app loading

[AntoSeti]

Hi everyone,

Happy 2020 to all :).

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).

Thanks

Shiny comes with its own implementation, and you may want to try the one from ShinyWidgets as well.

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.

@AntoSeti: you may want to try waiter.
