showReactGraph: Reactive log visualizer

In glin/reactlog: Easier Debugging with the Shiny Reactive Log

Description

Launches the reactive log visualizer with extra features:

• Interactive filtering on selected nodes

• Jump to the previous/next flush cycle (i.e. all white nodes)

Usage

showReactGraph(graph = getReactGraph(), time = TRUE,
  filter = getCurrentContext())

Arguments

graph	A reactive graph. Defaults to the reactive graph for the current Shiny session.
time	If TRUE, display the time for each reactive.
filter	Filter on a reactive observer or expression and its dependencies. Defaults to the current reactive context if present.

Note

Experimental. Current limitations include:

• Can only be launched from R like shiny::showReactLog()

• Interactive filtering limited to all connected nodes (both dependencies and dependents)

• Unable to tell when an observer is destroyed (stays grey forever)

See Also

shiny::showReactLog()

Examples

## Not run: 
# show the graph for most recent session
showReactGraph()

observe({
  # show the graph filtered on this observer and its dependencies
  showReactGraph()
})

## End(Not run)
