A stripped down rails app to demonstrate the problems with react-rails defining a window scope
on the server environment
windowCheckCode.js does a type check on window to determine the environment it is being
executed in, this code was extracted from https://github.com/yahoo/subscribe-ui-event
if (typeof window !== 'undefined') {
win = window;
doc = win.document || document;
body = doc.body;
}When running in the ExecJS environment the following error is thrown:
ReferenceError: document is not defined
