According to Chrome Lighthouse, the major slow down of our Shiny app comes from intially loading resources (JS, CSS) into the DOM:
Then, I -- sadly unsuccessfully --browsed the web for a solution or some hints on how to r eliminate these render-blocking resources in R Shiny (i.e., load them later). Besides these two abandoned quesions on StackOverflow and here on RStudio Community, I was unable to find any Shiny-related sources.
As the JS and CSS are loaded while loading the libraries, I assume it might be tricky to disentangle them. Still, I wonder if there is a common approach on how to overcome this and speed up the intial loading of the app.
Looking forward for some tips & ideas!
