import { withRouter } from 'react-router-dom';

const myComponent = ({ listen }) => {

  listen((location, action) => {
    // location is an object like window.location
    console.log(action, location.pathname, location.state)

  return <div>...</div>;

export default withRouter(myComponent);

If you are not using react-router, here is a javascript library you can look at that you can manage your session history.

You can use history.listen() function to detect the route change. Here is a example:

import createHistory from "history/createBrowserHistory"

const history = createHistory()

// Get the current location.
const location = history.location

// Listen for changes to the current location.
const unlisten = history.listen((location, action) => {
  // location is an object like window.location
  console.log(action, location.pathname, location.state)

// Use push, replace, and go to navigate around.
history.push("/home", { some: "state" })

// To stop listening, call the function returned from listen().

An alternative to handle state in React: the URL !, To retrieve that parameter (if it is indeed in the URL eg.

Query. String. Apart from the parameters that are part of the URL path, React the query string, if any, and makes it available to the component in a property  URL parameters are parameters whose values are set dynamically in a page’s URL.
