    import { render } from "react-dom";
    import {Router, Route, browserHistory} from "react-router";

    import {EmployeeList} from "./employeeList";
    import {EditForm} from "./edit";


    class App extends React. Component{ 
        render(){
            return (
                <Router history={browserHistory}>
                    <Route path={"/"} component={EmployeeList} />   
                </Router>
            );
        }
    }

    render(<App />, window.document.getElementById("app"));

This is employeeList js file.

    export class EmployeeList extends React. Component {
        constructor(props) {
            super(props);
        };

        render() {
                return (
                <div>
                    <h2>Basic Table</h2>

                    <table class="table table-dark table-striped">
                        <thead>
                            <tr>
                                <th>Id</th>
                                <th>First Name</th>
                                <th>Last Name</th>
                                <th>Button</th>
                            </tr>
                        </thead>
                        {student}
                    </table>
                </div>

You should use BrowserRouter from 'react-router-dom' instead of the Router .

The Router component is intended to be used when working with a custom history, so the history prop is required. To work with the react-router on the web browser, you should use the BrowserRouter from react-router-dom . Just for clarity, here is the Router docs , and the BrowserRouter docs

And your code should be:

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

...

class App extends React. Component{ 
    render(){
        return (
            <BrowserRouter>
                <Route path={"/"} component={EmployeeList} />   
            </BrowserRouter>
        );
    }
}
