javascript

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?

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. Link to react router: https://reacttraining.com/react-router/web/api/Route/render-func

Code example at codesandbox: https://codesandbox.io/s/z3ovqpmp44

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>
            );
        }
    }

And usage

<Route path="/greeting/:name" render={(props) => <Greeting text="Hello, " {...props} />} />

OLD VERSION

My preferred way is wrap the Comments component and pass the wrapper as a route handler.

This is your example with changes applied:

var Dashboard = require('./Dashboard');
var Comments = require('./Comments');

var CommentsWrapper = React.createClass({
  render: function () {
    return (
        <Comments myprop="myvalue" />
    );
  }
});

var Index = React.createClass({
  render: function () {
    return (
        <div>
            <header>Some header</header>
            <RouteHandler />
        </div>
    );
  }
});

var routes = (
  <Route path="/" handler={Index}>
    <Route path="comments" handler={CommentsWrapper}/>
    <DefaultRoute handler={Dashboard}/>
  </Route>
);

ReactRouter.run(routes, function (Handler) {
  React.render(<Handler/>, document.body);
});

如果你不想写包装，我想你可以这样做：

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}/>
);

Copying from the comments by ciantic in the accepted response:

<Route path="comments" component={() => (<Comments myProp="value" />)}/>

This is the most graceful solution in my opinion. It works. Helped me.
