Are you familiar with React-Router? You can change the name of the title page by placing a componentDidMount in the desired component, which will fire when the component is loaded. Then, you'll simply use document.title to target and change the page's title.

Here's an example , which I took from issue ticket #49 in the React-Router Github repository:

var Handler = React.createClass({
componentDidMount: function() {
document.title = "Amazing Page";
}
});
