react-router go back a page how do you configure history?

Question

Can anyone please tell me how I can go back to the previous page rather than a specific route?

When using this code:

var BackButton = React.createCla         


        

Answer 1

This is a working BackButton component (React 0.14):

var React = require('react');
var Router = require('react-router');

var History = Router.History;

var BackButton = React.createClass({
  mixins: [ History ],
  render: function() {
    return (
      {this.props.children}
    );
  }
});

module.exports = BackButton;

You can off course do something like this if there is no history:

{this.props.children}

function goBack(e) {
  if (/* no history */) {
    e.preventDefault();
  } else {
    this.history.goBack();
  }
}
