Why is React Router v6 not rendering my components? - javascript

I know this question has been asked a lot and I've looked at quite a lot of answers and articles including one on how to upgrade from React Router V5 to V6 since I'm used to V5. However, V6 is giving me a weird issue which I don't know how to fix or what am I doing wrong.
Here's my code below
App.js
import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';
import Login from './components/dashboard/Login';
import Profile from './components/dashboard/Profile';
import './resources/style/tutorApp.css';
export default class App extends Component {
static displayName = App.name;
render () {
return (
<Router>
<Routes>
<Route path="/" element={ <Profile /> } />
<Route path="/Login" element={ <Login /> } />
</Routes>
</Router>
);
}
}
Profile.js
import React, { Component } from 'react';
class Profile extends Component {
render() {
return (
<div>
<h1>This is my Profile Page.</h1>
</div>
);
}
}
export default Profile;
Login.js
import React, { Component } from 'react';
class Login extends Component {
render() {
return (
<div>
<h1>This is my Login page.</h1>
</div>
);
}
}
export default Login;
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
const baseUrl = document.getElementsByTagName('base')[0].getAttribute('href');
const rootElement = document.getElementById('root');
ReactDOM.render(
<BrowserRouter basename={baseUrl}>
<App />
</BrowserRouter>,
rootElement);
registerServiceWorker();
I just get a blank window in the browser. Nothing is rendered!
What is the problem?

You are mounting a router inside another router.
In ReactDom.render you're wrapping your app in BrowserRouter.
import { BrowserRouter } from 'react-router-dom';
// ...
ReactDOM.render(
<BrowserRouter basename={baseUrl}> // <-- this is the outer browser router
<App />
</BrowserRouter>,
rootElement
);
However inside your app you mount another BrowserRouter in your render method.
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';
// ...
render () {
return (
<Router> // <-- this is the nested browser router
<Routes>
<Route path="/" element={ <Profile /> } />
<Route path="/Login" element={ <Login /> } />
</Routes>
</Router>
);
}
To fix the problem simply remove one or the other.
The rest of your code looks fine.

React Router's useLoaderData Console Error

When I try using the useLoaderData hook from react-router-dom, it has been giving me the same error
Uncaught Error: useLoaderData must be used within a data router. See
https://reactrouter.com/routers/picking-a-router.
no matter what change I make in the Home Component, so that made me guess the issue is not from there.
This is what my Main.jsx looks like:
import React from 'react'
import ReactDOM from 'react-dom/client'
import { BrowserRouter } from 'react-router-dom'
import App from './App'
import './index.css'
ReactDOM.createRoot(document.getElementById('root')).render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>
)
My App.jsx:
import React from 'react'
import { Route, Routes } from 'react-router-dom'
import Home, { homeLoader } from './pages/Home'
import About from './pages/About'
import GlobalLayout from './GlobalLayout'
const App = () => {
return (
<>
<Routes>
<Route path='/' element={<GlobalLayout />}>
<Route index element={<Home />} loader={homeLoader} />
<Route path='/about' element={<About />} />
</Route>
</Routes>
</>
)
}
export default App
I think everything in my Home.jsx is fine
I have tried checking out the documentation attached to the error and its not helping.
In order to use the RRDv6.4 Data APIs a data router must be used. See Picking a Router.
Use the createBrowserRouter utility to create a Data router. The created router object is passed to the RouterProvider component. Any routes and components that you want or need to use the Data APIs necessarily need to be declared here at build time as part of the data router creation.
App.jsx
import React from 'react';
import {
createBrowserRouter,
createRoutesFromElements,
RouterProvider,
Route,
Routes
} from 'react-router-dom';
import Home, { homeLoader } from './pages/Home';
import About from './pages/About';
import GlobalLayout from './GlobalLayout';
const router = createBrowserRouter(
createRoutesFromElements(
<Route element={<GlobalLayout />}>
<Route path="/" element={<Home />} loader={homeLoader} />
<Route path="/about" element={<About />} />
</Route>
)
);
const App = () => {
return <RouterProvider router={router} />;
};
export default App;
Main.jsx
import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './index.css';
ReactDOM.createRoot(document.getElementById('root')).render(
<React.StrictMode>
<App />
</React.StrictMode>
);
createBrowserRouter
RouterProvider
createRoutesFromElements

How to fix error with Reactjs with making link

</>
)
}
export {Layout}
This code I making using tutorials from Youtube and official documentations but it don't work.
Please help. Thank
Routes need to be inside a tag or within a router created using createBrowserRouter.
In index.JS import BrowserRouter and replace React.StrictMode with it. Strict mode can cause things to render multiple times so I usually get rid of it.
import ReactDOM from 'react-dom/client';
import App from './App';
import { BrowserRouter } from “react-router-dom”;
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<BrowserRouter>
<App />
</BrowserRouter>
);
You should use all routing related actions under router context. You can achieve this by using BrowserRouter component as an HOC for <App />. You can find more here: https://reactrouter.com/en/main/router-components/browser-router
The Routes should have been wrapped by BrowserRouter component. It should look like this:
import { Layout } from "./Components/Layout";
import { BrowserRouter, Routes, Route, Link } from 'react-router-dom'
function App() {
return (
<>
<BrowserRouter>
<Routes>
<Route path="/" element={<Layout />} />
</Routes>
</BrowserRouter>
</>
);
}
export default App

react-router-dom v6 renders only default route

I'm starting a new project using React Router Dom v6 and I'm in trouble with one of the first steps: setting the routes for the App.
I just created two pages: AuthPage and DashboardPage and I would like to be able of rendering both of them if, from the browser, I navigate to:
localhost:PORT/ : should render DashboardPage
localhost:PORT/auth: should render AuthPage
but right no the only page rendered is DashboardPage even if I try to navigate to non-existing routes.
This is my code so far:
main.tsx
import { createRoot } from 'react-dom/client'
import { MemoryRouter as Router } from 'react-router-dom'
import { ThemeProvider } from '#mui/material/styles'
import { theme } from './theme'
import App from './App'
const root = createRoot(document.getElementById('root') as HTMLElement)
root.render(
<ThemeProvider theme={theme}>
<Router>
<App />
</Router>
</ThemeProvider>
)
App.tsx
import { Route, Routes } from 'react-router-dom'
import AuthPage from './pages/AuthPage'
import DashboardPage from './pages/DashboardPage'
import NotFoundPage from './pages/NotFoundPage'
import { routes } from './routes'
function App() {
return (
<Routes>
<Route path={routes.dashboard.url} element={<DashboardPage />} />
<Route path={routes.auth.url} element={<AuthPage />} />
<Route path={routes.notFound.url} element={<NotFoundPage />} />
</Routes>
)
}
export default App
routes.ts
export const routes = {
auth: {
url: '/auth'
},
dashboard: {
url: '/'
},
notFound: {
url: '*'
}
}
Use BrowserRouter instead of MemoryRouter :
import { createRoot } from 'react-dom/client'
import { BrowserRouter } from 'react-router-dom'
import { ThemeProvider } from '#mui/material/styles'
import { theme } from './theme'
import App from './App'
const root = createRoot(document.getElementById('root') as HTMLElement)
root.render(
<ThemeProvider theme={theme}>
<BrowserRouter>
<App />
</BrowserRouter>
</ThemeProvider>
)
As I know, exact option doesn't supported in react-router v6.
Try to use index option.
<Route path="/*">
<Route index element={< DashboardPage />} />
<Route path={routes.auth.url} element={<AuthPage />} />
// ... other routes
</Route>

React router dom routing to ItemDetail

I am doing a personal React.js project. I am trying to use react-router-dom, but I haven't been able to make it work. I did the BrowserRouter in the App.js. Till there the app works fine, but I cannot make the routing redirect dynamically to a map item. I tried to follow the documentation and some tutorials unsuccesfully. The data comes from the Star Wars API This is the code:
App.js:
import './App.css';
import { Route, BrowserRouter as Router, Routes } from "react-router-dom";
import Home from './components/Home';
import MovieDetail from './components/MovieDetail'
import Navbar from './components/Navbar';
function App() {
return (
<Router>
<>
<Navbar />
<Routes>
<Route exact path='/' element={<Home />} />
</Routes>
<Routes>
<Route exact path to='/:movieId' element={<MovieDetail />} />
</Routes>
</>
</Router>
);
}
export default App;
ItemDetail:
import { useEffect, useState } from "react";
import { useParams } from "react-router-dom";
const MovieDetail = () => {
const { movieId } = useParams();
const [result, setResult] = useState([]);
const fetchData = async () => {
const res = await fetch("https://www.swapi.tech/api/films/");
const json = await res.json();
setResult(json.result);
}
useEffect(() => {
fetchData();
}, []);
let movieMatch = (result.find(value) => value.properties.title == movieId)
return (
<div>
<h2>
{result
.find((value) => {value.properties.title == movieId})}
</h2>
</div>
);
}
export default MovieDetail;
UPDATE
This is a link to the whole code in codesand with updated App.js
From your code I'm assuming you're using React Router v6 in your project. Try the below code:
import './App.css';
import { BrowserRouter, Routes, Route } from "react-router-dom";
import Home from './components/Home';
import MovieDetail from './components/MovieDetail'
import Navbar from './components/Navbar';
function App() {
return (
<BrowserRouter>
<Routes>
<Navbar />
<Route path='/' element={<Home />} />
<Route path=':movieId' element={<MovieDetail />} />
</Routes>
</BrowserRouter>
);
}
export default App;
Checkout React Router's Documentation for more detail.
if you are using index.js as a wrapper for app.js <BrowserRouter /> or <Router /> in your case is not used in app.js it's used in index.js otherwise it will not work
index.js should look like this : -
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
function App() {
return <h1>Hello React Router</h1>;
}
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById("root")
);
**For example just Let's say you are having "/movies" route and you want when ever your app (route = "/") starts / loads up to be redirected to "/movies" **
then wrap the routing logic with *<Switch />* ,make use of Redirect property of router dom to redirect from "/" to "/movies" and use component instead of element to render the corresponding component plus dont wrap with <Routes> </Routes> every time you are doing the route as we used it in index.js
then app.js will be : -
import './App.css';
import { Route, BrowserRouter as Router, Routes } from "react-router-dom";
import Home from './components/Home';
import MovieDetail from './components/MovieDetail'
import Navbar from './components/Navbar';
function App() {
return (
<>
<Navbar />
<Switch>
<Route exact path='/movies' component={<Home />} />
<Route exact path to='movies/:movieId' component={<MovieDetail />}
// to redirect from "/" to "/movies"
<Redirect from="/" to="/students"></Redirect>
);
}

React Router Error: You should not use Route outside of Router

I'm just doing some basic routing in my react app and I've done it this way before so I'm pretty confused to as why it isn't working now.
The error I am getting says: You should not use <Route> or withRouter() outside a <Router>
I'm sure this is super basic so thanks for baring with me!
import React from 'react'
import { Route } from 'react-router-dom'
import { Link } from 'react-router-dom'
import * as BooksAPI from './BooksAPI'
import BookList from './BookList'
import './App.css'
class BooksApp extends React.Component {
state = {
books: []
}
componentDidMount() {
this.getBooks()
}
getBooks = () => {
BooksAPI.getAll().then(data => {
this.setState({
books: data
})
})
}
render() {
return (
<div className="App">
<Route exact path="/" render={() => (
<BookList
books={this.state.books}
/>
)}/>
</div>
)
}
}
export default BooksApp
You need to setup context provider for react-router
import { BrowserRouter, Route, Link } from 'react-router-dom';
// ....
render() {
return (
<BrowserRouter>
<div className="App">
<Route exact path="/" render={() => (
<BookList
books={this.state.books}
/>
)}/>
</div>
</BrowserRouter>
)
}
Side note - BrowserRouter should be placed at the top level of your application and have only a single child.
I was facing the exact same issue. Turns out that i didn't wrap the App inside BrowserRouter before using the Route in App.js.
Here is how i fixed in index.js.
import {BrowserRouter} from 'react-router-dom';
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>
document.getElementById('root')
);
