Intercept/handle browser’s back button in React-router?

Using react-router made the job simple as such:

import { browserHistory } from 'react-router';

componentDidMount() {
    this.onScrollNearBottom(this.scrollToLoad);

    this.backListener = browserHistory.listen((loc, action) => {
      if (action === "POP") {
        // Do your stuff
      }
    });
  }

componentWillUnmount() {
    // Unbind listener
    this.backListener();
}
