Does shiny modules have an overhead

Which one would be faster

  1. A single app using 3 data frames to create input widgets and dashboard


  1. A app broken down into 5 or 6 modules and one app file. Each dependent on same 3 data frames that are interlinked and passing them to and forth to one another.

Does it create the data again when I use a callmodule to save the data. And other questions like that..

No, the memory and runtime overhead should both be insignificant. Similar to breaking one big function into four smaller functions in regular R code.

Thanks for the reply I thought I am creating for 5 ot 6 copies of each dataframe on a different namespace everytime I create a module.

It means it is just one dataframe moving around in functions without any overhead Right???
