How is 'router' being assigned to the state?

[baj84]

As per the connected-react-router documentation, you must assign the router to the state, like so
const createRootReducer = (history) => combineReducers({ router: connectRouter(history), ... // rest of your reducers })

I can't see where this is being done in your code, but router is still assigned to the state. Where does this happen?

Thanks.
