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;

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.
I have an application built in React and Redux that's been working fine until I implemented a simple localStorage check to render either the App or an auth page I've called Gateway:
App.js
import React, { useState } from "react";
import { BrowserRouter as Router, Route, Switch } from "react-router-dom";
import { Provider } from "react-redux";
import store from "./redux/store";
import NavBar from "./components/NavBar";
import Settings from "./views/Settings";
import Gateway from "./views/Gateway";
import Profile from "./views/Profile";
import Signup from "./views/Signup";
import NewTestimonialPage from "./views/NewTestimonialPage";
import NotFoundPage from "./views/NotFoundPage";
import "./styles/App.scss";
function App() {
// new additions start here...
const [loggedIn, setLoggedIn] = useState(
localStorage.getItem("loggedIn") === "true"
);
if (!loggedIn) {
return <Gateway />;
}
...and end here
return (
<Router>
<Provider store={store}>
<NavBar />
<div className="navbar-dodger"></div>
<div className="App">
<Switch>
<Route exact path="/" component={Gateway} />
<Route path="/signup" component={Signup} />
<Route path="/settings/:userId" component={Settings} />
<Route path="/profile/:userId" component={Profile} />
<Route
path="/new-testimonial/:userId"
component={NewTestimonialPage}
/>
<Route path="/404" component={NotFoundPage} />
<Route component={NotFoundPage} />
</Switch>
</div>
</Provider>
</Router>
);
}
export default App;
Without the code between comments, everything was 100% fine.
Now, I throw this error:
Could not find "store" in the context of "Connect(EmailCheck)". Either wrap the root component in a <Provider>, or pass a custom React context provider to <Provider> and the corresponding React context consumer to Connect(EmailCheck) in connect options.
If I render the provider inside that if-block as well, it works. Why? Why do I need a store if I'm not using redux in any way inside Gateway?
If you are using redux inside <Gateway> component then your component must be wrapped in <Provider>
It should look like :
return (
<Router>
<Provider store={store}>
{!loggedIn ?? <Gateway /> : <YourApplication />}
</Provider>
</Router>
);
Create a component for the app like
YourApplication.js:
return (
<>
<NavBar />
<div className="navbar-dodger"></div>
<div className="App">
<Switch>
<Route exact path="/" component={Gateway} />
<Route path="/signup" component={Signup} />
<Route path="/settings/:userId" component={Settings} />
<Route path="/profile/:userId" component={Profile} />
<Route
path="/new-testimonial/:userId"
component={NewTestimonialPage}
/>
<Route path="/404" component={NotFoundPage} />
<Route component={NotFoundPage} />
</Switch>
</div>
<>
);
I am trying to create a website with React, but my code is not working and i dont understand why..
I have this code in index.js, because I want my header to always be there.
const element = <h1>Header</h1>; ReactDOM.render(element, document.getElementById('root'));
I have created a few components, and I have this code in my App.js
import React, {Component} from 'react';
import {BrowserRouter as Router, Route, Switch, Link, BrowserRouter} from 'react-router-dom';
import {Home} from './Components/Home';
import {About} from './Components/About';
import {Contact} from './Components/Contact';
import {Resume} from './Components/Resume';
import {Photos} from './Components/Photos';
import {NoMatch} from './Components/NoMatch';
class App extends Component {
render(){
return(
<React.Fragment> <Router> <switch>
<Route path="/" exact component={Home} />
<Route path="/about" component={About} />
<Route path="/contact" component={Contact} />
<Route path="/resume" component={Resume} />
<Route path="/photos" component={Photos} />
<Route component={NoMatch} />
</switch>
</Router>
</React.Fragment>
);
}
}
And all my components looks like this now, just temporarly:
import React from 'react'
export const About = () => (
<div>
<h2>About</h2>
</div>
)
The problem is that i only see "Header" on all pages, and when i change the path to localhost../About, it does not show anything else but "Header".
Why is not my code working and the code in my components showing in the different paths?
I've used the npm create-react-app and uses visualstudiocode. Thank you for the help, much appreciated :)
Btw, im following a tutorial and it is working for him but not me for some reason...
The Switch needs to be with a capital letter 'S'
<Router>
<Switch>
<Route path="/" exact component={Home} />
<Route path="/about" component={About} />
<Route path="/contact" component={Contact} />
<Route path="/resume" component={Resume} />
<Route path="/photos" component={Photos} />
<Route component={NoMatch} />
</Switch>
</Router>
Shouldn’t ‘switch’ be with a capital letter ( Switch )?
Is <switch> with lower case on purpose? It should be <Switch>
Anyway, I would like to see your code in a code sandbox if it's not the problem
I have already tried various solutions, I am currently using it, unfortunately GA only tracks one path ('/')
import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import '../sass/main.scss';
import {
HashRouter,
Route,
Switch,
} from 'react-router-dom';
const history = createHistory()
ReactGA.initialize('UA-XXXXXXX-1');
history.listen((location, action) => {
ReactGA.pageview(location.pathname + location.search);
console.log(location.pathname)
});
class Index extends Component {
render() {
return (
<>
<HashRouter history={history} >
<Route />
<ScrollUpButton ContainerClassName="AnyClassForContainer" />
<Header />
<Switch history={history}>
<Route exact path={"/"} component={() => <HomePage />}/>
<Route exact path={"/test"} component={() => <CategoryLinksNextPrev />}/>
<Route exact path={"/contact"} component={() => <Contact />}/>
<Route exact path={"/car/:category/"} component={CarCategory} />
<Route exact path={"/car/:category/:carname"} component={CarOnePageMain} />
<Route path="*" component={NotFound} />
</Switch>
<Footer />
</HashRouter>
</>
)
}
}
ReactDOM.render(<Index />, document.getElementById("index"));
In google analytics it only shows me one subpage, and exactly points to index.html
UPDATE
I found a very simple solution to this problem.
https://www.npmjs.com/package/react-router-ga
So that's my code now:
import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import '../sass/main.scss';
import {
HashRouter,
Route,
Switch,
} from 'react-router-dom';
import Analytics from 'react-router-ga';
class Index extends Component {
render() {
return (
<>
<HashRouter >
<Analytics id="UA-xxxxxxx-1" debug>
<ScrollUpButton ContainerClassName="AnyClassForContainer" />
<Header />
<Switch history={history}>
<Route exact path={"/"} component={() => <HomePage />}/>
<Route exact path={"/test"} component={() => <CategoryLinksNextPrev />}/>
<Route exact path={"/contact"} component={() => <Contact />}/>
<Route exact path={"/car/:category/"} component={CarCategory} />
<Route exact path={"/car/:category/:carname"} component={CarOnePageMain} />
<Route path="*" component={NotFound} />
</Switch>
<Footer />
</Analytics>
</HashRouter>
</>
)
}
}
ReactDOM.render(<Index />, document.getElementById("index"));
I had a similar issue recently.
It looks like Google Analytics loads on the page load. If you click on a link, GA will run again as the new page is loaded from scratch with a new URL.
You have to manually fire the GA page views when user moves around your single page application.

I keep on getting the error:
A 'Router' may have only one child element
when using react-router.
I can't seem to figure out why this is not working, since it's exactly like the code they show in their example: Quick Start
Here is my code:
import React from 'react';
import Editorstore from './Editorstore';
import App from './components/editor/App';
import BaseLayer from './components/baselayer';
import {BrowserRouter as Router, Route} from 'react-router-dom';
import {render} from 'react-dom';
const root = document.createElement('div');
root.id = 'app';
document.body.appendChild(root);
const store = new Editorstore();
const stylelist = ['https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css', 'https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.2.2/semantic.min.css', 'https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.2/animate.min.css', 'https://api.tiles.mapbox.com/mapbox-gl-js/v0.33.1/mapbox-gl.css'];
stylelist.map((link) => {
const a = document.createElement('link');
a.rel = 'stylesheet';
a.href = link;
document.body.appendChild(a);
return null;
});
render((
<Router>
<Route exact path="/" component={BaseLayer} />
<Route path="/editor" component={App} store={store} />
</Router>
), document.querySelector('#app'));
You have to wrap your Route's in a <div>(or a <Switch>).
render((
<Router>
<Route exact path="/" component={BaseLayer} />
<Route path="/editor" component={App} store={store} />
</Router>
), document.querySelector('#app'));
should be
render((
<Router>
<div>
<Route exact path="/" component={BaseLayer} />
<Route path="/editor" component={App} store={store} />
</div>
</Router>
), document.querySelector('#app'));
jsfiddle / webpackbin
This is an API change in react-router 4.x. Recommended approach is to wrap Routes in a Switch: https://github.com/ReactTraining/react-router/issues/4131#issuecomment-274171357
Quoting:
Convert
<Router>
<Route ...>
<Route ...>
</Router>
to
<Router>
<Switch>
<Route ...>
<Route ...>
</Switch>
</Router>
You will, of course, need to add Switch to your imports:
import { Switch, Router, Route } from 'react-router'
I Always use Fragment in react web and native ( >= react 16 )
import React, { Component, Fragment } from 'react'
import { NativeRouter as Routes, Route, Link } from 'react-router-native'
import Navigation from './components/navigation'
import HomeScreen from './screens/home'
import { RecipesScreen } from './screens/recipe'
class Main extends Component {
render() {
return (
<Fragment>
<Navigation />
<Routes>
<Fragment>
<Route exact path="/" component={HomeScreen} />
<Route path="/recipes" component={RecipesScreen} />
</Fragment>
</Routes>
</Fragment>
)
}
}
export default Main
I put all my <Route /> tags inside the <Switch> </Switch> tag like this.
<BrowserRouter>
<Switch>
<Route path='/' component={App} exact={true} />
<Route path='/form-example' component={FormExample} />
</Switch>
</BrowserRouter>
This solves the problem.
If you are nesting other components inside the Router you should do like.
<Router>
<div>
<otherComponent/>
<div>
<Route/>
<Route/>
<Route/>
<Route/>
</div>
</div>
</Router>
If you are using Reach Routers make sure the Code looks like this:
<Router>
<Login path="/" />
<Login path="/login" />
</Router>
Including these Components in a Div in the case of React Routers will make this work but In Reach Routers, Remove that Div Element.
you can also wrap all your route in a parent route which defaults to index page
<Router history={history}>
<Route path="/" component={IndexPage}>
<Route path="to/page" component={MyPage}/>
<Route path="to/page/:pathParam" component={MyPage}/>
</Route>
</Router>
I am using react-router-dom package with version 5.0.1 and it works perfectly fine with your code.
import { BrowserRouter as Router , Router, Link } from 'react-router-dom';
import Home from './pages/Home';
import About from './pages/About';
...
class App extends React.Component {
render() {
return (
<Router>
<ul>
<li><Link path='/'>Home</Link></li>
<li><Link path='/about'>About</Link></li>
</ul>
<Route path='/' exact component={Home} />
<Route path='/about' component={About} />
</Router>
);
}
}
export default App;
Not sure if my router might be too simple, or there was a change to this rule but was following along a tutorial that mentioned this limitation (A 'Router' may have only one child element) and it allowed me to add 3 routes without giving any errors. This is the working code:
function render() {
ReactDOM.render(
<BrowserRouter>
<Route exact path="/" component={App} />
<Route path="/add" component={AddAuthorForm} />
<Route path="/test" component={test} />
</BrowserRouter>
,
document.getElementById('root')
);
}
And this are my dependencies:
"react": "^16.13.1",
"react-dom": "^16.13.1",
"react-router-dom": "^5.1.2",
"react-scripts": "3.4.1",
This problem occurs when you don't have parent tag before <Route>inside <Router> so to resolve this problem keep the <Route>enclosed in a parent tag such as <div> , <p> etc.
Example -
<Router>
<p>
<Route path="/login" component={Login} />
<Route path="/register" component={Register} />
</p>
</Router>
