Server side rendering `window` behaves differently than Node.js? about react-rails

[ahangarha]

The window object is part of the browser's JavaScript environment and is not available on the server.

Hi @ahangarha - I understand that. The problem is that the package styled-components -- which is SSR friendly -- references window in the code for browser side behavior, and is guarded for a server-side context as mentioned in the issue above. However, in a react-on-rails environment, whether this is guarded or not seems to not matter. As the code is evaluated by ExecJS during the pre-render phase, the window keyword seems to be leading to an error.

@Judahmeek Any insight?

I'm so sorry! This was meant for the react_on_rails repo. Just now realizing.
