React-router V4 Dispatch Redux Action On Page Change

I would like an action to be dispatched and then intercepted by the reducers on every react-router page change. My use case is: I have the page state persisted in redux store. The

Solution 1:

You could create your history instance separately, and listen to that and dispatch an action when something changes.

Example

// history.js
import createHistory from 'history/createBrowserHistory';

const history = createHistory();

history.listen(location => {
  // Dispatch action depending on location...
});

export default history;

// App.js
import { Router, Route } from 'react-router-dom';
import Home from './components/Home';
import Login from './components/Login';
import history from './history';

class App extends React.Component {
  render() {
    return (
      <Router history={history}>
        <div>
          <Route exact path="/" component={Home} />
          <Route path="/login" component={Login} />
        </div>
      </Router>
    )
  }
}

Solution 2:

v4 has the location object which could be used to check if the app has navigated away from the current page.
