I continue to run into the above mentioned error despite my efforts to fix them. The terminal claims the application compiles without issue but nothing shows up on the browser. I found the error my looking at the console. Here is the index.js file for the Header component that the error is referring to:
import React from "react";
import { Route, Navigate, Router } from "react-router-dom";
import Navigation from "../../components/Navigation";
import About from "../../components/About";
import Portfolio from "../../components/Portfolio";
import Contact from '../../components/Contact';
import Resume from '../../components/Resume';
class Header extends React.Component {
render() {
return (
<Router>
<header>
<Navigation />
</header>
<div className="content">
<Route exact path="/" render={() => <Navigate to="/about" replace={true}/>} />
<Route path="/about" component={About} />
<Route path="/portfolio" component={Portfolio} />
<Route path="/contact" component={Contact}/>
<Route path="/resume" component={Resume}/>
</div>
</Router>
);
}
}
export default Header;
Here is the App.js:
import React from 'react';
import Header from './components/Header';
import Footer from './components/Footer';
import './App.css';
import 'bootstrap/dist/css/bootstrap.min.css';
import { Routes } from 'react-router-dom';
function App() {
return (
<div>
<Routes>
<Header />
<Footer />
</Routes>
</div>
);
}
export default App;
I can provide further code if it is needed.
In react-router-dom version 6 Routes components can have only Route or React.Fragment as a child component, and Route components can have only Routes or another Route component as parent. Header is not a Route component and fails the invariant.
Move the Router into app and render the Header and Footer components into it instead, then wrap the Route components in Routes.
App
function App() {
return (
<div>
<Router>
<Header />
<Footer />
</Router>
</div>
);
}
Header
Fix the Route components, they no longer use component or render to render the routed components, instead they now use an element prop to render ReactElements, i.e. JSX.
class Header extends React.Component {
render() {
return (
<div>
<header>
<Navigation />
</header>
<div className="content">
<Routes>
<Route path="/" element={<Navigate to="/about" replace />} />
<Route path="/about" element={<About />} />
<Route path="/portfolio" element={<Portfolio />} />
<Route path="/contact" element={<Contact />}/>
<Route path="/resume" element={<Resume />}/>
</Routes>
</div>
</div>
);
}
}
Though it may make more sense to move the routes into the app as content between the header and footer.
function App() {
return (
<div>
<Router>
<Header />
<div className="content">
<Routes>
<Route path="/" element={<Navigate to="/about" replace />} />
<Route path="/about" element={<About />} />
<Route path="/portfolio" element={<Portfolio />} />
<Route path="/contact" element={<Contact />}/>
<Route path="/resume" element={<Resume />}/>
</Routes>
</div>
<Footer />
</Router>
</div>
);
}

I'm programming in react, the truth is the first time that I program it in React.
in App.js I define the routes, I use the react-router-dom library, but I get the error of the title, the code is the following, what am I doing wrong, can you explain it to me, because I bring all the components.
import React from 'react';
import './App.css';
import 'materialize-css/dist/css/materialize.css';
import NavBar from './components/NavBar';
import ItemListContainer from './components/ItemListContainer';
import MoreSell from './components/ItemListMoreSell';
import ItemDetailContainer from './components/ItemDetailContainer';
import Cart from './components/Cart';
import { BrowserRouter, Routes, Route } from 'react-router-dom';
function App() {
return (
<div className="App">
<BrowserRouter>
<NavBar />
<MoreSell/>
<Routes>
<Route path="/" element={<ItemListContainer/>} />
<Route path="/category/:categoryID" element={<ItemListContainer/>} />
<Route path="/detail/:productID" element={<ItemDetailContainer/>} />
<Route path="/cart" element={<Cart/>} />
<ItemListContainer/>
</Routes>
</BrowserRouter>
</div>
);
}
export default App;
Thank you
ItemListContainer is causing the problem after the Cart route, since inside Routes you can only define route
function App() {
return (
<div className="App">
<BrowserRouter>
<NavBar />
<MoreSell/>
<Routes>
<Route path="/" element={<ItemListContainer/>} />
<Route path="/category/:categoryID" element={<ItemListContainer/>} />
<Route path="/detail/:productID" element={<ItemDetailContainer/>} />
<Route path="/cart" element={<Cart/>} />
</Routes>
</BrowserRouter>
</div>
);
}
export default App;
You have ItemListContainer/> as a child inside Routes>. Either delete this component, move it outside of Routes, or create a new route with it inside.
<Routes>
<Route path="/" element={<ItemListContainer/>} />
<Route path="/category/:categoryID" element={<ItemListContainer/>} />
<Route path="/detail/:productID" element={<ItemDetailContainer/>} />
<Route path="/cart" element={<Cart/>} />
<ItemListContainer/> //<-------------------------This is the error
</Routes>
I think the answer in your error message:
you need to remove < ItemListContainer /> from < Routes > ... </ Routes > container and move it to another place. For example:
function App() {
return (
<div className="App">
<BrowserRouter>
<NavBar />
<MoreSell/>
<Routes>
<Route path="/" element={<ItemListContainer/>} />
<Route path="/category/:categoryID" element={<ItemListContainer/>} />
<Route path="/detail/:productID" element={<ItemDetailContainer/>} />
<Route path="/cart" element={<Cart/>} />
</Routes>
<ItemListContainer/>
</BrowserRouter>
</div>
);
}
This question already has answers here:
How do I render components with different layouts/elements using react-router-dom v6
(2 answers)
Closed 8 months ago.
Header will appear in all components except ConfirmEmail. Basically I don't want the Header to appear when the ConfirmEmail component is opened. What should I do?
Router setup:
import React from 'react';
import {BrowserRouter,Routes ,Route} from 'react-router-dom'
import Header from "../Components/Header";
import 'bootstrap/dist/css/bootstrap.min.css';
import 'bootstrap/dist/js/bootstrap.bundle.min.js';
import Home from '../Components/Home';
import Contact from '../Components/Contact';
import Login from '../Components/Login';
import Register from '../Components/Register';
import ConfirmEmail from '../Components/SuccessEmailApproved';
const App = () =>{
return(
<BrowserRouter>
<Header/>// If confirmEmail component is opened, hide it here
<Routes>
<Route path="/" element={<Home/>} />
<Route path="/home" element={<Home/>} />
<Route path="/ev" element={<Home/>} />
<Route path="/contact" element={<Contact/>} />
<Route path="/iletisim" element={<Contact/>} />
<Route path="/login" element={<Login/>} />
<Route path="/giris" element={<Login/>} />
<Route path="/register" element={<Register/>} />
<Route path="/kayit" element={<Register/>} />
<Route path="/ConfirmEmail" element={<ConfirmEmail />} /> //I don't want the header component to appear if this is opened. but it will appear in other components.
</Routes>
</BrowserRouter>
);
}
export default App;
Update:
Tried the below solution and it's working, but is there a better way?
{window.location.pathname !== "/ConfirmEmail" ?<Header/>:<></>}
You could create a Layout.js component like below. It's kind of the common way to set up the same structure for multiple pages in React Router Dom v6.
import { Outlet } from "react-router-dom";
import Header from "../Header"; // ⚠️ verify it's the correct path
const Layout = () => {
return (
<>
<Header />
<Outlet />
</>
);
};
export default Layout;
And change App as below. Notice ConfirmEmail page is left out from the pages where you want Header:
// ⚠️ previous imports
import Layout from "./components/Layout"; // ⚠️ verify it's the correct path
const App = () =>{
return(
<BrowserRouter>
<Routes>
<Route element={<Layout />}>
<Route path="/" element={<Home/>} />
<Route path="/home" element={<Home/>} />
<Route path="/ev" element={<Home/>} />
<Route path="/contact" element={<Contact/>} />
<Route path="/iletisim" element={<Contact/>} />
<Route path="/login" element={<Login/>} />
<Route path="/giris" element={<Login/>} />
<Route path="/register" element={<Register/>} />
<Route path="/kayit" element={<Register/>} />
</Route>
<Route path="/ConfirmEmail" element={<ConfirmEmail />} />
</Routes>
</BrowserRouter>
);
}
export default App;
You can have as many layouts as you want (MainLayout, AuthLayout, Layout...). The setup is the same, an Outlet and a Route that has your Layout as element and wraps the pages for that Layout.
This is my App.js
import "./App.css";
import Header from "./component/layout/Header/Header.js";
import { BrowserRouter as Router, Route, Routes } from "react-router-dom";
import React from "react";
import Home from "./component/Home/Home.js";
function App() {
return (
<Router>
<Header />
<Route exact path="/" component={Home} />
<Footer />
</Router>
);
}
export default App;
This is my Home.js
const Home = () => {
return (
<Fragment>
<div className="banner">
<p>Welcome to My Website</p>
</div>
</Fragment>
);
};
export default Home;
Edit: i managed to remove the black page after wrapping the Route but the text in Home.js doesn't show "Welcome to My Website"
<Routes>
<Route exact path="/" component={Home} />
</Routes>
this code ^ removed the blank page but the result is that the text from Home.js "Welcome to My Website" didn't show. How can I route correctly to the Home component?
If you are using v6 react-router-dom, you have to replace component to element
<Routes>
{/* <Route exact path="/" component={Home} /> */}
<Route exact path="/" element={<Home />} />
</Routes>
I created a react app and use react-router-dom for navigation. WHen i wrapp the app.js with BrowseRouter the following error shows.
Error: A <Route> is only ever to be used as the child of <Routes> element, never rendered directly. Please wrap your <Route> in a <Routes>.
the following is my App.js
import {BrowserRouter, Route} from 'react-router-dom'
function App() {
return (
<BrowserRouter>
<div className="App">
<Header/>
<Route exact path="/">
<Home/>
</Route>
<Footer/>
</div>
</BrowserRouter>
);
}
You should wrap all the Route components in a Routes component, and render the components for each route on the element prop.
function App() {
return (
<div className="App">
<BrowserRouter>
<div className="App">
<Header />
<Routes>
<Route path="/" element={<Home />} />
</Routes>
<Footer />
</div>
</BrowserRouter>
</div>
);
}
import {BrowserRouter, Route,Switch} from 'react-router-dom'
function App() {
return (
<div className="App">
<Header/>
<BrowserRouter>
<Switch>
<Route exact path="/">
<Home/>
</Route>
</Switch>
</BrowserRouter>
<Footer/>
</div>
);
}
or in React-router-dom version 6 :
import {BrowserRouter, Route,Switch,Routes} from 'react-router-dom'
function App() {
return (
<div className="App">
<Header/>
<BrowserRouter>
<Routes>
<Route exact path="/">
<Home/>
</Route>
</Routes>
</BrowserRouter>
<Footer/>
</div>
);
}
I created the component NotFound and it works fine when I go to a page that doesn't exist. But the same page it's appearing in all my pages, not only the one that doesn't exist. This is the component:
import React from 'react'
const NotFound = () =>
<div>
<h3>404 page not found</h3>
<p>We are sorry but the page you are looking for does not exist.</p>
</div>
export default NotFound
And this is how I used it in the main page:
class MainSite extends Component {
render () {
return (
<div>
{/* Render nav */}
<Route path='/dashboard' component={Nav} />
<Route path='/retrospectives' component={Nav} />
<Route path='/users' component={Nav} />
<Route path='/projects' component={Nav} />
{/* Dashboard page */}
<ProtectedRoute exact path='/dashboard' component={DashboardPage} />
{/* Retrospectives page */}
<ProtectedRoute exact path='/retrospectives' component={RetrospectivesPage} />
{/* Users page */}
<ProtectedRoute exact path='/users' component={UsersPage} />
{/* Projects page */}
<ProtectedRoute exact path='/projects' component={ProjectsPage} />
{/* Retrospective related pages */}
<Route exact path='/retrospectives/:retrospectiveId' component={Retrospective} />
<Route exact path='/join-retrospective' component={JoinRetrospective} />
<ProtectedRoute exact path='/create-retrospective/:retrospectiveId' component={Retrospective} />
{/* OnBoarding pages */}
<ProtectedRoute exact path='/beta-code' component={BetaCodeAccess} />
<Route exact path='/auth-handler' component={AuthHandler} />
<Route exact path='/join-organization' component={JoinOrganization} />
</div>
)
}
}
export default MainSite
As you can see I use <Route path="*" component={NotFound} /> to create the 404 pages, but that component is appearing in every existing page as well. How can I fix this?
Try this one:
import { Switch, Route } from 'react-router-dom';
<Switch>
<Route path='/dashboard' component={Nav} />
<Route path='/retrospectives' component={Nav} />
<Route path='/users' component={Nav} />
<Route path='/projects' component={Nav} />
<Route path="" component={NotFound} />
</Switch>
All below example works fine:
<Route path="" component={NotFound} /> // empty ""
<Route path="*" component={NotFound} /> // star *
<Route component={NotFound} /> // without path
Or if you want to return a simple 404 message without any component:
<Route component={() => (<div>404 Not found </div>)} />
For those who are looking for an answer using react-router-dom v6, many things had changed. Switch for example doesn't exists anymore, you have to use element instead of component, ... Check this little example to get you an idea:
import React from 'react'
import ReactDOM from 'react-dom'
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom'
import './index.css'
import App from './App'
const Test = () => (
<h1>404</h1>
)
ReactDOM.render(
<React.StrictMode>
<Router>
<Routes>
<Route path='/' element={<App />} />
<Route path='*' element={<Test />}/>
</Routes>
</Router>
</React.StrictMode>,
document.getElementById('root')
)
With this you are defining your home route and all the other routes will show 404. Check the official guide for more info.
Try This:
import React from "react";
import { Redirect, Route, Switch, BrowserRouter } from 'react-router-dom';
import HomePage from './pages/HomePage.jsx';
import NotFoundPage from './NotFoundPage.jsx';
class App extends React.Component {
render(){
return(
<BrowserRouter>
<Switch>
<Route exact path='/' component={HomePage} />
<Route path="*" component={NotFoundPage} />
</Switch>
</BrowserRouter>
)
}
}
export default App;
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
Simply import Switch from react-router-dom and wrap all your Routes in the Switch Component. Also Important here is to note to keep your 404Page component at the very bottom(just before your switch ending tag) This way it will match each component with its route first. If it matches, it will render the component or else check the next one. Ultimately if none matching routes will be founded, it will render 404Page
react router is a headache for new coders. Use this code format. This is class component but you can make a functional component and use it.
import React from "react";
import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
import HomePage from './pages/HomePage.jsx';
import NotFoundPage from './NotFoundPage.jsx';
import Footer from './Footer';
class App extends React.Component {
render(){
return(
<Router>
<Routes>
<Route exact path='/' element={HomePage} />
<Route path="*" element={NotFoundPage} />
</Routes>
<Routes>
<Route path="/" element={Footer}/>
</Routes>
</Router>
)
}
}
export default App;
