Some common routes (taken from the react-router examples)

routes.js

import { Route } from 'react-router'

import App from 'components/App'
import Page1 from 'components/Page1'
import Page2 from 'components/Page2'
import Tab1 from 'components/Tab1'
import Tab2 from 'components/Tab2'

export default const routes = (
  <Route path="/" component={App}>
    <Route path="page1" component={Page1}>
      <Route path="tab1" component={Tab1} />
      <Route path="tab2" component={Tab2} />
    </Route>
    <Route path="page2" component={Page2}>
      <Route path="tab1" component={Tab1} />
      <Route path="tab2" component={Tab2} />
    </Route>
  </Route>
