I'm using the library react-cookie ( and I want to delete the user cookies when the browser or tab is closed. I used ComponentWillUnmount in my Approuter, but that doesn't work when the browser is closed. Anyone know how to achieve this?

import React from 'react';
import {Router, Route, Switch} from 'react-router-dom';
import history from '../data/history';
import { withCookies, Cookies } from 'react-cookie';
import { instanceOf } from 'prop-types';

class AppRouter extends React.Component{

static propTypes = {
    cookies: instanceOf(Cookies).isRequired


    const {cookies} = this.props;

        <Router history={history}>
                <div className="main-container">

export default withCookies(AppRouter);

The router does receive the cookies so why can't I remove it with componentWillUnmount? And how do I remove them?
