react-rails 🚀 - setTimeout is not defined

has no method 'setTimeout'

The Object in question is "global" which in most cases I'd assume would be window. I'm not sure what it ends up being within the react-rails pre-render. I'm guessing the pre-render environment doesn't provide these. Surely all JS environments should provide these methods?

I've gotten around this by adding this at the top of the generated webpack, but would like a better solution.

(function (global) {
global.clearTimeout = global.clearTimeout || function () {};
global.setTimeout = global.setTimeout || function () {};
}(this));

Essentially this means any methods passed to setTimeout will never be called, which should be fine for rendering purposes.

Looks like ExecJS doesn't support setTimeout: https://github.com/rails/execjs#faq (Or therubyracer: https://github.com/cowboyd/therubyracer/issues/325)

Glad you found a workaround!

@tbrd May I ask how you added that to the generated webpack? is there a way I can set in config to write that to the top of the compiled file? thanks.
