const PrivateRoute = ({ component: Component, ...rest }) => (

  <Route
    {...rest}
    render={(props) =>
      getToken() !== null ? (
        <Component {...props} />
      ) : (
        <Redirect
          to={{
            pathname: '/signin',
            state: { from: props.location }
          }}
        />
      )}
  />
);

const Root = () => (
  <Router>
    <React.Fragment>
      <Navbar />
      <Switch>
        <Route component={...} path='/...' /> // public
        <PrivateRoute component={...} path='/...' /> // private
      </Switch>
    </React.Fragment>
  </Router>
);

ReactDOM.render(<Root />, document.getElementById('root'));
registerServiceWorker();
