Making changes in Shiny apps in "real-time"

Redirected by Ryan Johnson to post here!

I was wondering if there are existing workflows/workarounds to make changes to shiny apps in real-time.

To illustrate:

Current workflow: make change -> run app -> something doesn't go as planned -> close app -> make change -> repeat

Desired workflow: run app -> make changes and reflect in real time

I hope that makes sense!

So you mean real time preview? As long as I know that functionality is not available anywhere, I think the reason is that the webapp itself doesn't run in R (web browsers don't have an R interpreter), the ui R code gets translated into html and Javascript when you execute runApp() so I guess it is not trivial to implement a robust auto refresh pipeline.

Ahh ok, that makes a lot of sense -- I figured as much, thanks!
