Is there an easier way to access the Router object from a ponent to do things like call transitionTo() without using the Navigation mixin? This is an ES6 ponent. Currently on an event like a button click, I have been writing something like this:

class Button extends React.Component {
  handleClick(e) {
    e.preventDefault();
    var router = this._reactInternalInstance._context.router;
    router.transitionTo('/search');
  }

  render() {
    return (
      <button onClick={this.handleClick.bind(this)}>
        {this.props.children}
      </button>
    );
  }
}

• react-router

• Confused, why not just this.context.router? – Henrik Andersson Commented Jul 17, 2015 at 5:48
• 5 Contexts in ES6 is undocumented at the moment. You accept the context in a parameter of the constructor and pass the context to the super. You can then access the context normally. Code examples in this react-router issue. – Mat Gessel Commented Jul 17, 2015 at 6:41

Per Mat Gessel's ment, adding the context as a parameter in the constructor will give you access to the router.

class Button extends React.Component {
  constructor(props, context) {
    super(props, context);
    this.context = context;      
  }

  handleClick(e) {
    e.preventDefault();
    this.context.router.transitionTo('/search');
  }

  render() {
    return (
      <button onClick={this.handleClick.bind(this)}>
        {this.props.children}
      </button>
    );
  }
}

Button.contextTypes = {
  router: React.PropTypes.object.isRequired
};
