Updating reactlog to reactlog 2.0

Hi all,

I just saw Barret Schloerke's presentation about reactlog 2.0, which looks awesome. I tried installing via github as recommended:


# tell shiny to log reactivity
options("shiny.reactlog" = TRUE)

but when I run show_reactlog(), I am still getting the old version of reactlog. Has anyone else had this problem and figured out how to use reactlog 2.0?



Maybe you are installing the new reactlog version just for your user, make sure to install it system wide.

Just want to make sure I'm going about this correctly. I tried: devtools::install_github('rstudio/reactlog', lib = "/Library/Frameworks/R.framework/Versions/3.5/Resources/library")
but this doesn't seem to fix it.


I have the same problem here. :frowning:
I notice I have similar issue when i try to run the exemple from the documentation ("Usage Section" : https://rstudio.github.io/reactlog/) : the old reactlog appears.

To use the new reactlog, I'm fairly certain you need to have reactlog installed and shiny v1.3 or higher (i.e., install the latest versions of reactlog/shiny with):

Perhaps I'm missing something, but from DESCRIPTION:

Package: reactlog
Title: Reactivity Visualizer for 'shiny'
Version: 1.0.0

and R/version.R suggests only "1" is available and known by the package:

reactlog_upgrade <- function(log) {
  version <- attr(log, "version")
  if (is.null(version)) {
    stop("'log' is missing a 'version' attribute.  This is required.")
  version <- as.character(version)
  if (identical(version, "1")) {

    "Versions available: 1\n",
    "Latest reactlog version: 1\n",
    "Version provided: ", version

None of the branches overtly suggest version 2. (I'd like to see the presentation on upcoming version 2, can you add a link for what you saw?)

Here's the talk
