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>
);

React router routers not showing

Closed 4 months ago.
Intro
I had created a react starter application
Problem
I had created a 3 components in /src/pages named AddCoupon, Addvertical, Addmetadata. Now then I created a file Routes.js in /src.
Routes.js
import React from 'react';
import {
BrowserRouter as Router,
Switch,
Route,
Link
} from "react-router-dom";
import AddCoupon from './pages/addCoupon';
import AddMetadata from './pages/addMetadata';
import AddVertical from './pages/addVertical';
import Login from './pages/login';
const Routes = () => {
return (
<>
<Router>
<Switch>
<Route path="/addcoupon">
<AddCoupon />
</Route>
<Route path="/addmetadata">
<AddMetadata />
</Route>
<Route path='/addvertical'>
<AddVertical />
</Route>
<Route path="/">
<Login />
</Route>
</Switch>
</Router>
</>
)
}
export default Routes
index.js
import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import { BrowserRouter as Router } from 'react-router-dom'
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<Router >
<App />
</Router>
</React.StrictMode>
);
reportWebVitals();
What I want?
So basically what I want is that when I type http:localhost:3000/addcoupon, it should render AddCoupon Component and same for other 2 components but right now it's showing nothing.
I dont want to use any navbar. What I want is simply when I hit the endpoints mentioned in Route.js, it should render that component.
Router 6 uses different syntax compared to earlier versions. Please check out the documentation:
https://reactrouter.com/en/v6.3.0/getting-started/overview
For your particular case, you need to remove switch, and pass element to route, and wrap all Route elements in Routes element, like so:
const Routes = () => {
return (
<>
<Routes>
<Route path="/addcoupon" element={<AddCoupon />}/>
<Route path="/addmetadata" element={<AddMetadata />}/>
<Route path='/addvertical' element={<AddVertical />}/>
<Route path="/" element={<Login />}/>
</Routes>
</>
)
}
In order for routes to work, you also need to wrap App element in Router element, like below:
import ReactDOM from 'react-dom'
import { BrowserRouter as Router } from 'react-router-dom'
import App from './App'
import './styles/index.scss'
ReactDOM.render(
<Router>
<App />
</Router>,
document.getElementById('root')
)
Final step, render Routes inside of App element or wherever you want to use it:
const App = () => {
return <Routes/>
}
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.
I have problem with router-dom. I am working according to youtube tutorial, I cannot resolve below error:
[landingPageLayout] is not a component. All component children of must be a or <React.Fragment>. I would be greateful for some guidance.
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import { BrowserRouter } from 'react-router-dom';
import App from './App';
import reportWebVitals from './reportWebVitals';
ReactDOM.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);
App.js
import './App.css';
import { Routes, Route } from 'react-router-dom';
import landingPageLayout from './components/layouts/landingPageLayout';
import homePage from './components/pages/homePage';
const App = () => {
return (
<Routes>
<landingPageLayout>
<Route path="/">
<homePage/>
</Route>
</landingPageLayout>
</Routes>
);
}
landingPageLayout.js
import React from 'react';
import Header from '../navigation/header';
const landingPageLayout = ({...otherProps}) => {
return (
<div>
<Header/>
</div>
)
}
export default landingPageLayout;
As Nicholas said in comments, your react components should always be capitalized.
Other than that, Routes component only accepts or <React.Fragment> as children so you can't add your layout like that. What you can do is something like this:
const App = () => {
return (
<Routes>
<Route
path='/*'
element={
<LandingPageLayout>
<HomePage />
</LandingPageLayout>
}
/>
</Routes>
);
}
If you have several routes that need this layout, you should replace HomePage with another component that has all the routes. For example we can call it PrivateRoutes. Then in code above you replace <HomePage /> with <PrivateRoutes /> and then your PrivateRoutes component should look like this:
const PrivateRoutes = () => {
return (
<Routes>
<Route path="home" element={<HomePage />} />
<Route path="page1" element={<Page1 /> />
//rest of routes
</Routes>
);
}
I'm having issues with my project, actually i'm trying to handle a 404 page when the user enters different url outside of the Routes in my App, but using my knowledge of React and react-router only needs to put the last route has no path and exact path wrapped by a Switch from react-router but not work well, the home page is rendering the Home and the NotFound components at same time.
I've tried to remove Container component inside the Router but that makes that all of the components after MenuBar disappears.
I've tried to put path='*' in the last Route having 2 components rendered in the same page.
A picture of what i'm talking about:
2 components at same time
My project have 3 principal files:
1.- Index.js :
import ReactDOM from 'react-dom';
import * as serviceWorker from './serviceWorker';
import ApolloProvider from './ApolloProvider';
import 'semantic-ui-css/semantic.min.css';
import 'animate.css/animate.min.css';
import './App.css';
ReactDOM.render(ApolloProvider, document.getElementById('root'));
serviceWorker.unregister();
2.- ApolloProvider.js (using Apollo with GraphQL) :
import React from 'react';
import App from './App';
import ApolloClient from 'apollo-client';
import { InMemoryCache } from 'apollo-cache-inmemory';
import { createHttpLink } from 'apollo-link-http';
import { ApolloProvider } from '#apollo/react-hooks';
const httpLink = createHttpLink({
uri: 'http://localhost:5000/graphql'
});
const client = new ApolloClient({
link: httpLink,
cache: new InMemoryCache()
});
export default (
<ApolloProvider client={client}>
<App />
</ApolloProvider>
);
3.- And finally App.js :
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import { Container } from 'semantic-ui-react';
import MenuBar from './Components/MenuBar';
import Home from './Pages/Home';
import Login from './Pages/Login';
import Register from './Pages/Register';
import NotFound from './Pages/404';
const App = props => (
<Router>
<Switch>
<Container>
<MenuBar />
<Route exact path='/' component={Home} />
<Route exact path='/login' component={Login} />
<Route exact path='/register' component={Register} />
<Route path='*' component={NotFound} />
</Container>
</Switch>
</Router>
);
export default App;
I only need to render Home component when the user visits '/' but it's weird how react-router is rendering two components at same time, please le me know if you find where i'm wrong or a solution for that, i'll being posting updates if i find a solution or whatever.
Thanks in advance mates!.
Thanks to #skyboyer and #Hugo Dozois the issue was fixed, this is the updated App.js for future references:
const App = props => (
<Router>
<Container>
<MenuBar />
<Switch>
<Route exact path='/' component={Home} />
<Route exact path='/login' component={Login} />
<Route exact path='/register' component={Register} />
<Route path='*' component={NotFound} />
</Switch>
</Container>
</Router>
);
Best Regards!
Today when I started up the iMac to continue working on the ReactJS app...it doesn't load...
What I mean by "load" is, it doesn't display the content of any page.
Error:
Uncaught TypeError: Cannot read property 'getCurrentLocation' of undefined
If you need the code of App.js and index.js
here they are:
App.js:
import React, { Component } from 'react';
import Header from './pages/Header';
import Footer from './pages/Footer';
import './css/App.css';
class App extends Component {
render() {
return (
<div className="App">
<Header />
{/*Content*/}
<div> App Page </div>
<Footer />
</div>
);
}
}
export default App;
index.js:
import { Router, Route, History } from 'react-router';
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
// CSS
import './css/index.css';
// Pages
import About from './pages/About';
import Register from './pages/Register';
import Cart from './pages/Cart';
import Thanks from './pages/Thanks';
import Faq from './pages/Faq';
import Contact from './pages/Contact';
import Error from './pages/Error';
ReactDOM.render((
<Router history={History}>
<Route path="/" component={App}>
<Route path="/pages/about" component={About}/>
<Route path="/pages/Register" component={Register}/>
<Route path="/pages/Cart" component={Cart}/>
<Route path="/pages/Thanks" component={Thanks}/>
<Route path="/pages/Error" component={Error}/>
<Route path="/pages/Faq" component={Faq}/>
<Route path="/pages/Contact" component={Contact}/>
</Route>
</Router>
), document.getElementById('root'))
According to your comment, your history object is undefined. Please try importing browserHistory instead of History and pass that into your router.
versions before React-Router v4 (Which I am assuming you are using since you are importing Router:
import { Router, Route, browserHistory } from 'react-router';
...
....
<Router history={browserHistory}>
<Route path="/" component={App}>
React-Router v4:
Instead of importing Router/browserHistory, you import browserRouter, which is a router that creates it's own history instance. it would look like this:
import { BrowserRouter, Route } from 'react-router';
...
...
<BrowserRouter>
<Route path="/" component={App}>
