These functions were temporarily ripped out of Shiny and moved to the htmltools package. We've discovered that it's safe to keep including them in shiny; as long as the functions in shiny and the functions in htmltools are identical, the user won't receive a conflict warning.

\description{
|
|
Provides an interactive browser-based tool for visualizing reactive
|
|
dependencies and execution in your application.
|
|
}
|
|
\details{
|
|
To use the reactive log visualizer, start with a fresh R session and
|
|
run the command \code{options(shiny.reactlog=TRUE)}; then launch your
|
|
application in the usual way (e.g. using \code{\link{runApp}}). At
|
|
any time you can hit Ctrl+F3 (or for Mac users, Command+F3) in your
|
|
web browser to launch the reactive log visualization.
|
|
|
|
The reactive log visualization only includes reactive activity up
|
|
until the time the report was loaded. If you want to see more recent
|
|
activity, refresh the browser.
|
|
|
|
Note that Shiny does not distinguish between reactive dependencies
|
|
that "belong" to one Shiny user session versus another, so the
|
|
visualization will include all reactive activity that has taken place
|
|
in the process, not just for a particular application or session.
|
|
|
|
As an alternative to pressing Ctrl/Command+F3--for example, if you
|
|
are using reactives outside of the context of a Shiny
|
|
application--you can run the \code{showReactLog} function, which will
|
|
generate the reactive log visualization as a static HTML file and
|
|
launch it in your default browser. In this case, refreshing your
|
|
browser will not load new activity into the report; you will need to
|
|
call \code{showReactLog()} explicitly.
|
|
|
|
For security and performance reasons, do not enable
|
|
\code{shiny.reactlog} in production environments. When the option is
|
|
enabled, it's possible for any user of your app to see at least some
|
|
of the source code of your reactive expressions and observers.
