// CustomRoutes.js
export default [
  <Route exact path="/login" component={LoginPage} noLayout />,
  <Route exact path="/forgot-password" component={ForgotPassword} noLayout />,
  <Route exact path="/confirm-password" component={ConfirmForgotPassword} noLayout />,
  <PrivateRoute path="/" loggedIn={localStorage.getItem("access_token")} component={dashboard} />

// PrivateRoute.js
import React from "react";
import { Redirect, Route } from "react-router-dom";

const PrivateRoute = ({ path, component: Component, ...rest }) => {
  const isLoggedIn = localStorage.getItem("access_token");

  return (
    <Route
      path={path}
      {...rest}
      render={props => isLoggedIn 
        ? <Component {...props} />
        : <Redirect to={{ pathname: "/login", state: { from: props.location } }} />
      }
    />

export default PrivateRoute;

// App.js
const App = () => (
  <Admin
    theme={myTheme}
    dashboard={dashboard}
