The default react-router is used as such:

```
import * as React from 'react';
import { Router, Route, hashHistory } from 'react-router';

const routing = (
    <Router history={hashHistory}>
        <Route path="/login" component={Login}/>
    </Router>   
};

```

When I include the "react-router-relay" library, it adds functionality to the Router. Namely it adds 2 properties to the Router component (render and environment):

```
import * as React from 'react';
import * as Relay from 'react-relay';
import * as useRelay from 'react-router-relay';
import { Router, Route, hashHistory, applyRouterMiddleware } from 'react-router';

const routing = (
    <Router history={hashHistory} render={applyRouterMiddleware(useRelay)} environment={Relay.Store}>
        <Route path="/login" component={Login}/>
    </Router>   
};

```

How would I go about augmenting the react-router typings? 

I've tried a bunch of approaches, latest being: 

```
import { Router } from 'react-router';

declare module 'react-router' {
    namespace Router {
        export interface RouterProps {
            environment?: any
        }
    }
}

```

As I need to extend the namespace "Router" and the interface "RouteProps" under it. 

Link to React router typings: <https://www.npmjs.com/package/@types/react-router>

The React-router-relay library does not have any typings itself.
