reactjs - React-Router with React 13.3+ -

i can't figure out how use relatively recent (react 13+) version of react-router . example on current readme suggests integrating rendering router directly (with routes defined via child route elements). official overview doc seems advise using router.run. react-router examples use former. none work me: different errors depending on use:

• when attempting use react-router rendering router element directly "uncaught error: invariant violation: needs valid location”
• when attempting use react-router running router.run routes, “uncaught typeerror: cannot read property 'touppercase' of null”

here simplified version of how use it, using webpack requires irrelevant, if have access react , router work.

var react = require('react'); var router = require('react-router'); var defaultroute = router.defaultroute; var route = router.route; var routehandler = router.routehandler; var link = router.link;  var comp0 = require('./comp0.jsx'); var comp1 = require('./comp1.jsx'); var comp2 = require('./comp2.jsx');  var app = react.createclass({ render: function () {     return (         <div>             <div >                 <li><link to="comp0">comp0</link></li>                 <li><link to="comp1">comp1</link></li>                 <li><link to="comp2">comp2</link></li>             </div>             <div>                 <routehandler {...this.props}/>             </div>         </div>      );     } });  var routes = (   <route name="app" path="/" handler={app}>       <route name="comp1"  handler={comp1}/>       <route name="comp2"  handler={comp2}/>       <defaultroute name="comp0"  handler={comp0}/>   </route> );   router.run(routes, function (handler) {    react.render(<handler />, document.body); });
