Can be simplified:

export { default as App } from './App'
export { default as Home } from './Home'
export { default as Foo } from './Foo'
export { default as Admin } from './Admin'
export { default as Login } from './Login'

@yurtaev thank you for submitting this, Im sorry it kind of got lost in the churn of pulling stuff together for version 2.0. Theres an example for react router v4 now here - https://github.com/mjrussell/redux-auth-wrapper/tree/master/examples/react-router-4

Feel free to submit a follow up PR if you want to improve anything there
