React 6.4.0 Common headers for all routers

Question

I'm starting a React project using react-router-dom version 6.4.0 but I can't create a common header for all routes.

App.js - This is the file where I added RouterProvider

import logo from './logo.svg';
import './App.css';
import { Link, Outlet, RouterProvider } from "react-router-dom";
import { routers } from "./routes/routes";

function App() {
  return (
    <RouterProvider router={routers}>
      <div>Header</div>
      <Outlet />
    </RouterProvider>
  );
}

export default App;

routes.js - In this file I will create all the routes

import { createBrowserRouter, redirect } from "react-router-dom";
import About from "../pages/About/About";
import Home from "../pages/Home/Home";
import { getUser, isAuthenticated } from "../sso/authUtil";

const authLoader = () => {
  if (!isAuthenticated()) {
    return redirect("https://google.com");
  } else {
    return getUser();
  }
};

export const routers = createBrowserRouter([
  {
    path: "/",
    element: <Home />,
    loader: authLoader,
  },
  {
    path: "/about",
    element: <About />,
  },
]);

Home.js - This file is the home page and contains links to other pages as well as the title

import React from "react";
import { Link, Outlet, useLoaderData } from "react-router-dom";

const Home = () => {
  const loaderData = useLoaderData();

  return (
    <>
      <div>Header</div>
      <Link to="/">Home</Link>
      <Link to="/about">About</Link>
      <div>Home: {loaderData}</div>{" "}
      <Outlet />
    </>
  );
}
 
export default Home;

About.js - This is a normal component that represents about

import React from "react";

const About = () => {
  return <div>About</div>;
};

export default About;

I want the Home and About components to have the title at the top when they load.

Even in react-router-dom@6.4.0, routing with generic UI rendering layout still works fine.

Create a layout route component that renders the public header component and an Outlet for nested routes.

Example:

const Layout = () => (
  <>
    <CommonHeader />
    <Outlet />
  </>
);

Import and render Layout on the layout route in the configuration.

const routers = createBrowserRouter([
  {
    element: <Layout />,
    children: [
      {
        path: "/",
        element: <Home />,
        loader: authLoader
      },
      {
        path: "/about",
        element: <About />
      }
    ]
  }
]);

...

function App() {
  return <RouterProvider router={routers} />;
}
