In Webpack 2, System.import does not currently work with server-rendering but I’ve shared some notes about how to work around this on StackOverflow.

one of the problems I have encountered with server render and code split is that server does synchronous render while client side is async. This leads to react warning that hash does not match since server returned content and client returned null from getComponent . I wonder if you were able to resolve this kind of warnings?
