EmbeddedGist allows a gist to be embedded in a React application

super(props);
this.gist = props.gist;

loading: true,

};
}
// The Gist JSON data includes a stylesheet to add to the page
// to make it look correct. `addStylesheet` ensures we only add
// the stylesheet one time.
addStylesheet = (href) => {
if (!this.stylesheetAdded) {
this.stylesheetAdded = true;
var link = document.createElement('link');
link.type = "text/css";
link.rel = "stylesheet";
link.href = href;
document.head.appendChild(link);
}
}
componentDidMount() {
// Create a JSONP callback that will set our state
// with the data that comes back from the Gist site
var gistCallback = EmbeddedGist.nextGistCallback();
window[gistCallback] = function(gist) {
this.setState({
loading: false,
src: gist.div
});
this.addStylesheet(gist.stylesheet);
}.bind(this);
var url = "https://gist.github.com/" + this.props.gist + ".json?callback=" + gistCallback;

}
// Add the JSONP script tag to the document.
var script = document.createElement('script');

document.head.appendChild(script);
}
render() {

}
}
}
EmbeddedGist.propTypes = {
gist: React.PropTypes.string.isRequired, // e.g. "username/id"

// Each time we request a Gist, we'll need to generate a new
// global function name to serve as the JSONP callback.

      // file: React.PropTypes.string, // to embed a single specific file from the gist
