I'm using react-leaflet with gatsby, a static site generation framework. As long as I'm in development mode everything is ok, but as soon as I try to generate the static bundle webpack reports the following error:

Generating HTML failed Error: ReferenceError: window is not defined

looks like this happens when you import leaflet
https://github.com/PaulLeCam/react-leaflet/blob/master/src/Map.js#L3
according to the react docs
using window is only allowed in componentDidMount() : "Initialization that requires DOM nodes should go here. "
Others seem to have the same problem:
webpack/react-starter#37
gatsbyjs/gatsby#309
and solved it by using require instead of import and doing this conditionally...

What do you think?
Thanks
