Hard to detect an Error on first render

I am not sure where the problem lies but this is the problem I see.

if you make some error inside render (non syntactical ) like a variable is `undefined` and you will never get to know where is the error for the first time project start.

For example , let's say we forgot to add [this](https://github.com/erikras/react-redux-universal-hot-example/blob/master/src/containers/Home/Home.js#L11) line and start the project with `npm start` it will not show any error but it will never complain and browser will be in infinite loading 😢

Any idea... hack...workarounds ??
