How is routing done in react-router-dom version 6?

I am having issues with routing in react-router-dom v6. My code is as follows :
import './App.css';
import Header from './Header';
import Home from './Home';
import { BrowserRouter as Router, Routes, Link } from "react-router-dom";
function App() {
return (
//BEM
<Router>
<div className="app">
<Routes>
<Route path="/" element={[<Header />, <Home />]} />
</Routes>
</div>
</Router>
);
}
export default App;
Nothing gets rendered.
Please help.

You should be giving a single component to element property. Assuming that you wanna Header on top of every route, try with this :
import './App.css';
import Header from './Header';
import Home from './Home';
import { BrowserRouter as Router, Routes, Link } from "react-router-dom";
function App() {
return (
//BEM
<Router>
<div className="app">
<Header />
<Routes>
<Route path="/" element={<Home/>} />
</Routes>
</div>
</Router>
);
}
export default App;
If you want to have Header only on path /, a cleaner way is to put it inside Home. Otherwise you could do it like so:
import { BrowserRouter as Router, Routes } from "react-router-dom";
import './App.css';
import Header from './Header';
import Home from './Home';
function App() {
return (
<Router>
<div className="app">
<Routes>
<Route path="/" element={<><Header/><Home/></>} />
</Routes>
</div>
</Router>
);
}
export default App;

Try to wrap multiple elements in Fragment
<Route path="/" element={<><Header/><Home/></>}/>

Have you tried wrapping them in fragment?
<Route path="/" element={<><Header/><Home/></>}/>

Routing not working with react-router-dom

I'm working on one of my friend's half-built React Project. I'm trying to route my react-app with react-router-dom. The components inside the <switch> are not working. Here's my
App.js
import React from 'react';
import Header from './components/Header';
import Main from './components/Main';
import Footer from './components/Footer';
import ProcessInput from './components/ProcessInput';
// Import react-router-dom
import { BrowserRouter as Router, Switch, Route} from 'react-router-dom';
function App() {
return(
<Router>
<div className="App">
<Header />
<Switch>
<Route path="/" exact component={Main} />
<Route path="/process" component={ProcessInput} />
</Switch>
<Footer />
</div>
</Router>
);
}
export default App;
Main.js
import React from 'react';
import Slider from './Slider';
import Card1 from './Card1';
import Card2 from './Card2';
import Prompt from './Prompt';
class Main extends React.Component {
render() {
return (
<div>
<main>
<Slider />
<Card1 />
<Card2 />
<Prompt />
</main>
</div>
)
}
}
export default Main;
The <Header /> and <Footer /> which are outside the <Switch> are showing anyways as intended. But, I want the Main component to be loaded as a root component (Launcher).
There are no errors on the console.
Please help me get to know what am I doing wrong. Thanks in advance :)

<Route path="/" exact>
<Main/>
</Route>
<Route path="/process"><ProcessInput/>
</Route>
This is the old way to do it. You can try this

Why wouldn't React Router work with <Switch>?

I'm learning React router, tried to build a pretty basic application like this Home.js:
import React from 'react';
import About from '../pages/About';
import { HashRouter as Router, Switch, Route, Link } from "react-router-dom";
const Navbar = () => {
return (
<Router>
<div>
<nav>
<ul>
<li>
<Link to="/">HOME</Link>
</li>
<li>
<Link to="/about-us">ABOUT US</Link>
</li>
</ul>
</nav>
<Switch>
<Route path="/about-us">
<About />
</Route>
<Route path="/">
<Home />
</Route>
</Switch>
</div>
</Router>
)
}
const Home = () => {
return (
<>
<Navbar />
</>
)
}
export default Home;
Then in index.js render Home page:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import Home from './pages/Home';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(
<React.StrictMode>
<Home />
</React.StrictMode>,
document.getElementById('root')
);
serviceWorker.unregister();
Problem is, Home wouldn't render in localhost:3000, terminal showed Compiled successfully! but when loading localhost:3000, it just spins forever with nothing rendered. However, if I remove the element it rendered. Folder structure set like this:
src
--pages
----About.js
----Home.js
index.js
Can anyone help?

You've created yourself an infinite loop from what it looks like. Your index.js returns your Home component, which then returns the Navbar, which has a router, which then returns the Home component, which then repeats that cycle over and over again.
This is the approach I would take, which will show the Navbar on both the about and home page, and will only show one of the pages at a time based on the current route.
// Navbar.js
const Navbar = () => {
return (
<nav>
<ul>
<li>
<Link to="/">HOME</Link>
</li>
<li>
<Link to="/about-us">ABOUT US</Link>
</li>
</ul>
</nav>
)
}
export default Navbar;
// Layout.js
import React from 'react';
import Navbar from './Navbar';
import About from '../pages/About';
import Home from '../pages/Home';
import { HashRouter as Router, Switch, Route, Link } from "react-router-dom";
const Layout = () => {
return (
<Router>
<Navbar />
<Switch>
<Route path="/about-us">
<About />
</Route>
<Route path="/">
<Home />
</Route>
</Switch>
</Router>
)
}
export default Layout;
// index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import Layout from './components/Layout';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(
<React.StrictMode>
<Layout />
</React.StrictMode>,
document.getElementById('root')
);
serviceWorker.unregister();
src
--components
----Navbar.js
----Layout.js
--pages
----About.js
----Home.js
index.js

text for h1 tag is not showing in browser

I am trying to display text in h1 tags but only about but about.js displays text. First one is shop.js component and second file is app.js file.
import React from 'react';
import './App.css';
function Shop() {
return (
<div>
<h1>Shop page</h1>
</div>
);
}
export default Shop;
My App component:
import React from 'react';
import Nav from './Nav';
import Shop from './Shop';
import About from './About';
import Home from './Home';
import './App.css';
import {BrowserRouter as Router,Switch,Route} from 'react-router-dom';
function App() {
return (
<Router>
<div className="App">
<Nav />
<Switch>
<Router path="/" exact component={Home} />
<Route path="/about"component={About} />
<Router path="/shop" component={Shop} />
</Switch>
</div>
</Router>
);
}
export default App;

Your routes and the Shop component itself look fine, so I'm guessing you just forgot to export the Shop component:
export function Shop() {
return (
<div>
<h1>Shop page</h1>
</div>
);
}

try adding shop route before home route like this:
<Route path="/about"component={About} />
<Router path="/shop" component={Shop} />
<Router path="/" exact component={Home} />

Why isn't my navigation bar rendering in React?

This is the code I have, I believe I have imported everything correctly, I am using React mdl to style it and copied and pasted the navbar code.
I also installed react dom router correctly, the individual pages display but the navbar itself doesn't on the landing page.
Can anyone help me? Thanks
App.js
import React, { Component } from "react";
import "./App.css";
import { Layout, Header, Navigation, Drawer, Content } from "react-mdl";
import Earth from "./earth.jpg";
import Main from "./components/main";
import { Link } from "react-router-dom";
class App extends Component {
render() {
return (
<div style={{ height: "300px", position: "relative" }}>
<Layout style={{ background: "src{Earth} center / cover" }}>
<Header transparent title="Title" style={{ color: "white" }}>
<Navigation>
Link
Link
Link
Link
</Navigation>
</Header>
<Drawer title="Title">
<Navigation>
<Link to="/aboutme">About Us</Link>
<Link to="/projects">Projects</Link>
<Link to="/resume">Resume</Link>
<Link to="/contact">Contact</Link>
</Navigation>
</Drawer>
<Content>
<div className="page-content">
<Main />
</div>
</Content>
</Layout>
</div>
);
}
}
export default App;
main.js
import React from 'react';
import { Switch, Route} from 'react-router-dom';
import LandingPage from './landingpage';
import AboutMe from './aboutme';
import Contact from './contact';
import Projects from './projects';
import Resume from './resume';
const Main = () => (
<Switch>
<Route exact path="/" component = {LandingPage} />
<Route path="/aboutme" component = {AboutMe} />
<Route path="/contact" component = {Contact} />
<Route path="/projects" component = {Projects} />
<Route path="/resume" component = {Resume} />
</Switch>
)
export default Main;
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import 'react-mdl/extra/material.css';
import 'react-mdl/extra/material.js';
import { BrowserRouter } from 'react-router-dom';
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>
, document.getElementById('root'));
serviceWorker.unregister();

You need to wrap your App component with BrowserRouter from react-router-dom.
You can do this inside you App component, or better in index.js like this:
import { BrowserRouter } from "react-router-dom";
ReactDOM.render(<BrowserRouter><App/></BrowserRouter>, rootElement);
