 If you use something like [React Router](https://github.com/rackt/react-router), you might also want to express your data fetching dependencies as static `fetchData()` methods on your route handler components. They may return [async actions](../advanced/AsyncActions.md), so that your `handleRender` function can match the route to the route handler component classes, dispatch `fetchData()` result for each of them, and render only after the Promises have resolved. This way the specific API calls required for different routes are colocated with the route handler component definitions. You can also use the same technique on the client side to prevent the router from switching the page until its data has been loaded.
