React - Migrating to React Router 4

Question

I am in the process of migrating my React App from React-Router-3 to React-Router-4 and I am having a few issues. The layout of my application is as follows.

build
node_modules
public
src
  AboutScreen
  ContactScreen
  HomeScreen
  LoginScreen
  SignUpScreen
  WorkRequestScreen
  App.js
  index.js
  routes.js
  serviceWorker.js
package.json
package-lock.json

I am getting the following error:

./src/index.js: Line 8: Unexpected use of 'history' no-restricted-globals

When I remove the history={history} from index.js , I get the following error.

TypeError: Cannot read property 'location' of undefined

I have been following the following tutorial to migrate from 3 to 4.

My route.js looks like this:

import React from 'react';
import { Route, Redirect, Router, Switch } from 'react-router-dom';
import createHashHistory from 'history/createHashHistory';
import App from './App';

import Home from './HomeScreen/Home';
import WorkReq from './WorkRequestScreen/WorkReq';
import About from './AboutScreen/About';
import Contact from './ContactScreen/Contact';
import Login from './LoginScreen/Login';
import Signup from './SignUpScreen/Signup';

const history = createHashHistory();
const routes = () => (
  <Router history={history}>
    <Switch>
      <Route exact path="/workReq" component={WorkReq}/>
      <Route exact path="/about" component={About}/>
      <Route exact path="/contact" component={Contact}/>
      <Route exact path="/login" component={Login}/>
      <Route exact path="/signup" component={Signup}/>
      <Route exact path="/" component={Home}/>
    </Switch>
  </Router>
);

export default routes;

My index.js looks like this:

import React from 'react';
import ReactDOM from 'react-dom';
import * as serviceWorker from './serviceWorker';

import { Route, Redirect, Router, Switch } from 'react-router-dom';
import routes from './routes'; 

ReactDOM.render(<Router history={history} routes={routes}/>, 
document.getElementById('root'));

serviceWorker.unregister();

Answer 1

Passing history explicitly isn't required as Route is passed history implicitly as prop. ¹

I'd remove history prop passed to Router from the index.js and also remove it from Router in routes.js
