Answer 1

I am using react-router-dom package with version 5.0.1 and it works perfectly fine with your code.

import { BrowserRouter as Router , Router, Link } from 'react-router-dom';
import Home from './pages/Home';
import About from './pages/About';
...

class App extends React.Component {
  render() {
    return (
      <Router>
        <ul>
          <li><Link path='/'>Home</Link></li>
          <li><Link path='/about'>About</Link></li>
        </ul>
        <Route path='/' exact component={Home} />
        <Route path='/about' component={About} />
      </Router>
    );
  }
}

export default App;

I put all my <Route /> tags inside the <Switch> </Switch> tag like this.

    <BrowserRouter>
        <Switch>
            <Route path='/' component={App} exact={true} /> 
            <Route path='/form-example' component={FormExample} />
        </Switch>
    </BrowserRouter>

This solves the problem.

You have to wrap your Route's in a <div>(or a <Switch>).

render((
  <Router>
    <Route exact  path="/" component={BaseLayer} />
    <Route path="/editor" component={App} store={store} />
  </Router>
), document.querySelector('#app'));

should be

render((
  <Router>
    <div>
       <Route exact  path="/" component={BaseLayer} />
       <Route path="/editor" component={App} store={store} />
    </div>
  </Router>
), document.querySelector('#app'));

Answer 4

you can also wrap all your route in a parent route which defaults to index page

<Router history={history}>    
   <Route path="/" component={IndexPage}>
      <Route path="to/page" component={MyPage}/>
      <Route path="to/page/:pathParam" component={MyPage}/>
   </Route>    
</Router>
