detectEvents() results in Turbolinks is not defined

[swrobel]

Help us help you! Please choose one:

• My app crashes with react-rails, so I've included the stack trace and the exact steps which make it crash.
• My app doesn't crash, but I'm getting unexpected behavior. So, I've described the unexpected behavior and suggested a new behavior.
• I'm trying to use react-rails with another library, but I'm having trouble. I've described my JavaScript management setup (eg, Sprockets, Webpack...), how I'm trying to use this other library, and why it's not working.
• I have another issue to discuss.

I've tried this in a large react-rails app that I've been trying to upgrade to 2.0 as well as a fresh app, neither of which includes turbolinks. I was attempting to debug why ReactRailsUJS.mountComponents() doesn't seem to be running automatically, which is what led me to attempt to call ReactRailsUJS.detectEvents(). I do not see any errors in the console when my page loads, only after calling detectEvents().

> ReactRailsUJS.detectEvents()

Same issue here, can it be used without Turbolinks? Our app extensively use react-router, that conflicts with Turbolinks, would go for disabling the latter, but breaks page loading. We're calling mountComponents() manually as well, but nothing happens
Thanks

It looks like this line is causing the error, right?

react-rails/react_ujs/src/events/detect.js

Line 12 in b39860b

if (typeof Turbolinks.EVENTS !== "undefined") {

Maybe the file should be update to something like

if (typeof Turbolinks !== "undefined" && ...)

?

Can we make a PR on this? @reactjs

@rmosolgo Can you give me permission on NPM please?
Not sure what you need to grant me publish, but my account is: https://www.npmjs.com/~bookofgreg

I'll push this out as part of 2.3.1 I think.

Thanks.
