I have the following structure for my React.js application using React Router:
var Dashboard = require('./Dashboard');
var Comments = require('./Comments');
var Index = React.createClass({
render: function () {
return (
<div>
<header>Some header</header>
<RouteHandler />
</div>
);
}
});
var routes = (
<Route path="/" handler={Index}>
<Route path="comments" handler={Comments}/>
<DefaultRoute handler={Dashboard}/>
</Route>
);
ReactRouter.run(routes, function (Handler) {
React.render(<Handler/>, document.body);
});
I want to pass some properties into the Comments component.
(normally I'd do this like <Comments myprop="value" />)
What's the easiest and right way to do so with React Router?

If you'd rather not write wrappers, I guess you could do this:
class Index extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<h1>
Index - {this.props.route.foo}
</h1>
);
}
}
var routes = (
<Route path="/" foo="bar" component={Index}/>
);
UPDATE
Since new release, it's possible to pass props directly via the Route component, without using a Wrapper. For example, by using render prop.
Component:
class Greeting extends React.Component {
render() {
const {text, match: {params}} = this.props;
const {name} = params;
return (
<React.Fragment>
<h1>Greeting page</h1>
<p>
{text} {name}
</p>
</React.Fragment>
);
}
}
Usage:
<Route path="/greeting/:name" render={(props) => <Greeting text="Hello, " {...props} />} />
