im using react router v6 and i every time i use initializing for authentication in my main file it shows this error. i cant find a solution in the internet for it. i want to render some routes only when there is a user but now it doesnt render anything.
AuthNavigator
import React, { useState, useEffect } from 'react';
import app from './firebase';
import { Router, Routes, Route } from 'react-router-dom';
import AuthStack from './stacks/AuthStack';
import AppStack from './stacks/AppStack';
import StaticStack from './stacks/StaticStack';
function AuthNavigator() {
const [initializing, setInitializing] = useState(true);
const [user, setUser] = useState(() => app.auth().currentUser);
useEffect(() => {
const unsubscribe = app.auth().onAuthStateChanged((user) => {
if (user) {
setUser(user);
} else {
setUser(null);
}
if (initializing) {
setInitializing(false);
}
});
// cleanup subscription
return unsubscribe;
}, []);
if (initializing) return 'Loading....';
return (
<Router>
<Routes>
<Route path="*" element={<StaticStack />} />
<Route path="auth/*" element={<AuthStack user={user} />} />
<Route path="app/*" element={<AppStack user={user} />} />
</Routes>
</Router>
);
}
export default AuthNavigator;
App.js
import React from 'react';
import './App.css';
import AuthNavigator from './AuthNavigator';
import { Router } from 'react-router-dom';
function App() {
return (
<Router>
<AuthNavigator />
</Router>
);
}
export default App;
I had the same issue. My issue is because of the following reason.
I had a Header component which consists of NavLink which is a router component. I placed this Header component inside the App component. My App component was like this:
function App() {
return(
<Header/>
<Router>
<Routes>
<Route path="/" element={<Homepage/>}/>
<Route path="/shop" element={<Shop/>}/>
<Route path="/signin" element={<Signin/>}/>
</Routes>
</Router>
)
}
In the above App component, I have placed Header component outside of Router. Since in the Header component I have used NavLink which is a Router component caused this error. Then I moved Header component into the Router component then it worked fine. Finally my code looked like this:
function App() {
return(
<Router>
<Header/>
<Routes>
<Route path="/" element={<Homepage/>}/>
<Route path="/shop" element={<Shop/>}/>
<Route path="/signin" element={<Signin/>}/>
</Routes>
</Router>
)
}
Already wrapped in Router?
if your component is already wrapped in a Router. Make sure you are importing useLocation from react-router-dom instead of react-router. this worked for me.
Make sure that your App component in index.js is wrapped with BrowserRouter like this
const app = (
<Provider store={store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>
);
In case you run into this problem when running a test, don't forget to wrap your import of App in Router as well. My crude example is below.
import { render, screen } from '#testing-library/react';
import { BrowserRouter } from 'react-router-dom';
import { App } from '../App';
test('renders Box', () => {
render(
<BrowserRouter>
<App />
</BrowserRouter>
);
const boxElement = screen.getByLabelText('box-outline');
expect(boxElement).toBeInTheDocument();
});
I had the same error coming up from inside a test. The component I was testing contained a NavLink component, and I wasn't rendering a Router in the test.
This error disappeared after wrapping my component in question with BrowserRouter.
I had this problem when using {useLocation} from 'react-router-dom'
function App() {
const { pathname, hash, key } = useLocation();
//function using pathname hash and key
return(
<Router>
<Header/>
<Routes>
<Route path="/" element={<Homepage/>}/>
<Route path="/shop" element={<Shop/>}/>
<Route path="/signin" element={<Signin/>}/>
</Routes>
</Router>
)
}
throws the same error even with the in the correct place
I fixed it by explicitly wrapping the useLocation() within the router
function App() {
return(
<Router>
<Header/>
<Inner/>
</Router>
)
}
function Inner() {
const { pathname, hash, key } = useLocation();
//function using pathname hash and key
return(
<Routes>
<Route path="/" element={<Homepage/>}/>
<Route path="/shop" element={<Shop/>}/>
<Route path="/signin" element={<Signin/>}/>
</Routes>
)
}
I had this error because Vite was bundling two copies of the same version of react-router-dom... check the outputted bundle for * React Router DOM and see how many copies there are.
If that's the case, the solution will differ. In my scenario I think it's because I was referencing other local npm packages using file:... once I switched to a npm workspace that fixed it.
So i fixed like this structure
index.js
import { BrowserRouter } from 'react-router-dom'
<Provider store={store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>
App.js
import { Route, Routes, Navigate } from 'react-router-dom'
<Layout>
<Routes>
<Route path="/" element={<Navigate to="/home" />} />
<Route path="/home" element={<Home />} />
{...}
<Route path="*" element={<NotFound />} />
</Routes>
</Layout>
Layout.js
<Fragment>
<Header></Header>
<main className="container">{props.children}</main>
</Fragment>
Header.js
import { Link, NavLink } from 'react-router-dom'
<header className={classes.header}>
<nav>
<NavLink
className={(navData) => (navData.isActive ? classes.active : '')}
to="/search"
>
Search
</NavLink>
</nav>
</header>
App.test.js
import { BrowserRouter } from 'react-router-dom';
it('renders learn react link', async () => {
render(<BrowserRouter><App /></BrowserRouter>)
const linkElement = await screen.findByText(/home/i)
expect(linkElement).toBeInTheDocument()
})
in my case, I faced this error when I used the HOC and context provider and placed my Routing component as the context.provider's child, and export my Provider component by HOC like this:
class Provider extends Component {
render() {
return (
<Context.Provider
value={{
something: this.state.something
}}
>
<Routing />
</Context.Provider>
);
}
}
export default HOC(Provider)
im my case, the problem was putting BrowserRouter inside App.js file, solved it by moving this into index.js file and wrapping it around App.js
Former Index.js
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<Provider store={store}>
<React.StrictMode>
<PersistGate persistor={persistor} >
<App/>
</PersistGate>
</React.StrictMode>
</Provider>
);
reportWebVitals();
Former App.js
import { BrowserRouter, Routes, Route, useLocation} from "react-router-dom";
const App = () => {
const {pathname} = useLocation()
return (
<div className='app'>
<BrowserRouter>
<Routes>
<Route path='/*' element={<LandingPage />} />
</Routes>
</BrowserRouter>
</div>
);
};
export default App;
New Index.js
import { BrowserRouter } from 'react-router-dom';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<Provider store={store}>
<React.StrictMode>
<PersistGate persistor={persistor} >
<BrowserRouter >
<App/>
</BrowserRouter>
</PersistGate>
</React.StrictMode>
</Provider>
);
reportWebVitals();
New App.js
import { Routes, Route, useLocation} from "react-router-dom";
const App = () => {
const {pathname} = useLocation()
return (
<div className='app'>
<Routes>
<Route path='/*' element={<LandingPage />} />
<Route path='/registeration' element={<Registration />} />
</Routes>
</div>
);
};
export default App;
Try this:
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
I testing my React App and I have an error of all Link react router dom in my views.
Index.js
import {
BrowserRouter as Router,
Switch,
Route
} from "react-router-dom";
function App({props}) {
return (
<div>
<Navbar />
<Switch>
<Route path="/" exact component={Homepage} appProps={props}/>
<Route path="/accueil" exact component={Homepage} appProps={props}/>
<Route component={Error} />
</Switch>
<Footer />
</div>
);
}
ReactDOM.render(
<Router>
<App />
</Router>,
document.getElementById("fatboar")
);
Homepage.js
import { Link } from 'react-router-dom';
export default function Homepage(props) {
return (
<Link to="/ajouter-ticket" className="primary-btn mt-5">Je participe</Link>
)
}
How my Link is outside of my router ?
The Link is navigate to /ajouter-ticket and as I see from your code you never put a Route to this Link due to this you navigate to the Error Component
and if you read the react-router-dom doc
you will see that when you navigate to something that doesn't define in the Switch Route go to the Route Without a path
React Router Dom Doc
<Route path="/ajouter-ticket" exact component={SomeComponent} appProps={props}/>
also, why do you have to routes to the HomePage?
Clicking on a NavLink was not updating my app. The NavLink is expected to update a todos list based on a filter link.
The solution for that was to extract the route into a separate stateless functional component :
const MyRoutes = () => (
<Route path='/:filter?' component={App} />
);
const Root = ({store}) => (
<Provider store={store}>
<Router>
<MyRoutes/>
</Router>
</Provider>
);
This works.
But with the same Route inside the Router, the NavLink does not trigger a new todo list.
What can explain that I have to extract the route into a separate component ?
You don't need to do this. The right way is importing the Switch from react-router-dom, and use it like this:
import { Switch, BrowserRouter as Router, Route } from 'react-router-dom'
const Root = ({store}) => (
<Provider store={store}>
<Router>
<Switch>
<Route path='/:filter' component={App} />
</Switch>
</Router>
</Provider>
);
If you want to define a main Route, you need to use the exact prop of the component Route:
<Route exact path='/:filter' component={App} />
EDIT: To use the exact, your route needs to be inside a Switch
I am trying to implement routing for my app which is built with react and redux. I have wrapped in so that route handlers can get access to the store.But somehow my routing logic is not working.
This piece of code was working fine
export default class Root extends Component {
render() {
return (
<Provider store={this.props.store}>
<div>
<App />
</div>
</Provider>
);
}
}
But when I replace with the below code it is not showhing anything on my localhost.
export default class Root extends Component {
render() {
return (
<Provider store={this.props.store}>
<div>
<Router>
<Route path="/" component={App} />
</Router>
</div>
</Provider>
);
}
}
I am trying to figure out what I am doing wrong. Any help will be appreciated.
I am assuming your project is browser based project. So , you can make use of <BrowserRouter> if your website/app is hosted on a dynamic server.
You can wrap it like :
import {BrowserRouter, Route} from 'react-router-dom';
export default class Root extends Component {
render() {
return (
<Provider store={this.props.store}>
<div>
<BrowserRouter>
<Route path="/" component={App} />
<BrowserRouter>
</div>
</Provider>
);
}
}
if your web is backed by static server make use of <HashRouter>

I think you're supposed to use one of the higher level router components like BrowserRouter. See if this works:
return (
<Provider store={this.props.store}>
<div>
<BrowserRouter>
<Route path="/" component={App} />
</BrowserRouter>
</div>
</Provider>
);
I am building a small project to test the React Router 4. So far so good, my url updates and my props.locations shows up with withRouter. But I can't seem to change my navBar base on the props.location.
This is what my Routes look like:
<Provider store={ store }>
<BrowserRouter onUpdate={() => window.scrollTo(0, 0)}>
<div className="root">
<App/>
<Switch>
<Route exact path="/" component={HomePageContainer}/>
<Route eact path="/signin" component={SignInContainer}/>
<Route eact path="/reviews" component={Reviews}/>
<Route path="/favorites" component={Favorites}/>
<Route render={() => (
<p>Page Not Found</p>
)}/>
</Switch>
</div>
</BrowserRouter>
</Provider>
My component basically contains my HeaderBar and navBar, I have messages thats in navBar that I want to change so I would have title of the page, My App looks like this:
const App = (props) => {
let toRender = null;
if(props.location.pathname !== '/signin'){
toRender = (
<div>
<HeaderContainer />
<NavBarContainer />
</div>
);
} else {
toRender = null;
}
return(
<div className="App">
{ toRender }
</div>
);
}
I can import my navBar container into each of the routes i have for '/', '/reviews', and '/favorites'. But I don't think that would be a modular way to do it. I also have a shouldComponentUpdate lifecycle method inside NavBar, and I tested with a console.log to print something when it does update when I switch url, but it doesn't. Does anyone have any suggestions on a clean solution to pass in the props to my NavBar without importing it into every single one of the components? I also tried putting App component in the place of Route so I would have:
<App exact path="/" component={HomePageContainer}/>
<Route eact path="/signin" component={SignInContainer}/>
<App eact path="/reviews" component={Reviews}/>
<App path="/favorites" component={Favorites}/>
But then my Components aren't rendering besides the App. I'm not sure what's happening or why it's not rendering the components. Any suggestions would be much appreciate it. Thank you.
