I'm new to react and am having trouble with react routing. The pages arent getting displayed. I will attach my code below

These are my files, all the import routes are proper, This code used to work before I used react routing. I have no idea why it isn’t working right now, would really appreciate it if anyone could help me solve this. I’ve been using react for less than a month now.

index.js

import React from "react";
import ReactDOM from "react-dom";
import App from "./components/App"

ReactDOM.render(<App />, document.getElementById("root"))

HomePage.jsx

import React from "react";
import Navbar from "../components/Navbar";

function HomePage() {
    return (
        <div>
            <Navbar />
            <h1>Homescreen</h1>
        </div>
    )
}

export default HomePage;

ProductScreen.jsx

import React from "react";

export default function ProductPage() {
    return (
        <h1>ProductPage</h1>
    )
}

App.jsx

import React from "react";
import { Route, BrowserRouter as Router } from "react-router-dom";

// importing components
import Footer from "./Footer";
import Navbar from "./Navbar";

// importing pages
import ProductPage from "../pages/ProductScreen";
import HomePage from "../pages/HomePage";


function App() {
    return (
        <Router>
            <Navbar />
            <main>
                <Route path="/" component={HomePage} > </Route>
                <Route path="/product/:id" component={ProductPage} > </Route>
            </main>
            <Footer />
        </Router>
    )
}

export default App

Navbar.jsx

import React from "react";

function Navbar() {
    return (
        <header class="nav navbar">
            <h3>Amazona</h3>
            <div class="navbar-items">
                <a href="cart.html">Cart</a>
                <a href="signin.html">Sign in</a>
            </div>
        </header>
    )
}

export default Navbar;

Footer.jsx

import React from "react";

function Footer() {
    return (
        <footer>
            <p>All rights reserved</p>
        </footer>
    )
}
export default Footer;

>Solution :

If you don’t know which version you use . please check package.json and search react-router-dom . Then you will see the version.
(React router dom v6)
If you use link ,You need to use router and routes. I think no error is shown your project. This is the documentation

https://reactrouter.com/docs/en/v6/getting-started/installation#create-react-app

This is demo code of routes , route

       import * as React from "react";
       import { Routes, Route, Link } from "react-router-dom";

       function App() {
        return (
         <div className="App">
            <h1>Welcome to React Router!</h1>
             <Routes>
               <Route path="/" element={<Home />} />
               <Route path="about" element={<About />} />
            </Routes>
        </div>
      );
     }

If you Use V5

 import {
   BrowserRouter,
   Switch,
   Route,
   Link,
   useRouteMatch
  } from "react-router-dom";

 function App() {
   return (
     <BrowserRouter>
      <Switch>
        <Route exact path="/">
         <Home />
       </Route>
       <Route path="/users">
         <Users />
       </Route>
    </Switch>
  </BrowserRouter>
 ); 
}
