In every React project I used to have two starting files: App.js and index.js. I know that is totally possible to remove the App.js and working only with the index.js file. In that case I do not have any problem with react-router v6, I could include the routes directly in the index.js file and I everything works fine.
My problem is when I am trying to use react-router v6 with both files at the same time. If I put the routes on the App.js file and after that I try to render the App with BrowserRouter I have several errors. If I remove that it works fine, but I want to understand if what I am doing is correct and why.
My App.js looks like this:
import React from "react";
import { createBrowserRouter, RouterProvider } from "react-router-dom";
import "./App.css";
import ExerciseDetail from "./pages/ExerciseDetail";
import Homepage from "./pages/Homepage";
const router = createBrowserRouter([
{
path: "/",
element: <Homepage />,
},
{
path: "/exercise/:id",
element: <ExerciseDetail />,
},
]);
function App() {
return <RouterProvider router={router} />;
}
export default App;
And my Index.js:
import React from 'react';
import ReactDOM from 'react-dom/client';
import { BrowserRouter} from "react-router-dom";
import './index.css';
import App from './App';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>
);
As I said before, if I remove BrowserRouter it works fine but I am not sure if that is correct.
You dont neccesary use 'BrowserRouter' in index.js because you are using 'createBrowserRouter' in app.js.
So, if you try to use both files, you should remove the BrowserRouter in index.js and use only the createBrowserRouter function.
You can see the implementation in React Router documentation
Be careful if you need to use nested routes, because you need to configure the project differently.
You can try to put the BrowserRouter into an App.js.
Maybe it helps.
import { StrictMode } from 'react';
import ReactDOM from 'react-dom';
import { App } from './App';
ReactDOM.render(
<StrictMode>
<App />
</StrictMode>,
document.getElementById('app-root')
);
import { BrowserRouter, Switch, Route } from 'react-router-dom';
import Main from './Pages/Main/Main';
import NewNote from './Pages/NewNote/NewNote';
import './App.css';
export const App = () => {
return (
<BrowserRouter>
<Switch>
<Route path='/' exact component={Main} />
<Route path='/new-note' component={NewNote} />
</Switch>
</BrowserRouter>
);
};

Im routing a page to the root, but its showing up as a blank page, no matter what js file I use. Not sure whats wrong, havent used react since last year but looks like they've updated react-router-dom so it doesnt use Switch anymore. Anyone know the correct syntax so the page shows up? Here are the files:
WebRoutes.js
import React from "react";
import { Routes, Route } from 'react-router-dom';
import { useNavigate } from "react-router-dom";
// Webpages
import App from './App';
import Welcome from './welcome';
import SignUp from './Signup'
export default function WebRoutes() {
return (
<Routes>
<Route path='/'>
<Welcome />
</Route>
</Routes>
);
}
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import WebRoutes from './WebRoutes';
import reportWebVitals from './reportWebVitals';
ReactDOM.render(
<React.StrictMode>
<WebRoutes />
</React.StrictMode>,
document.getElementById('root')
);
In react-router-dom#6 the Route components don't render routed content as children, they use the element prop. Other Route components are the only valid children of a Route in the case of building nested routes.
export default function WebRoutes() {
return (
<Routes>
<Route path='/' element={<Welcome />} />
</Routes>
);
}
Ensure that you have rendered a router around your app.
import { BrowserRouter as Router } from 'react-router-dom';
ReactDOM.render(
<React.StrictMode>
<Router>
<WebRoutes />
</Router>
</React.StrictMode>,
document.getElementById('root')
);

I've tried browsing a few similar queries but haven't been able to solve my issue. I downloaded a template (am new to React) where the single-page application was entirely built in App.js. I've since been trying to add functionality to add additional pages - but keep getting the error "React Router: Cannot read property 'pathname' of undefined."
My App.js
import React from 'react'
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom'
import Mint from './components/pages/Mint'
import LandingPage from './components/pages/LandingPage'
const App = () => {
return (
<Router>
<Routes>
<Route exact path="/" element={<Mint/>}/>
<Route path="/home" element={<LandingPage/>}/>
</Routes>
</Router>
);
}
export default App;
My index.js
import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import reportWebVitals from "./reportWebVitals";
import store from "./redux/store";
import { Provider } from "react-redux";
import { BrowserRouter } from "react-router-dom";
import { ConnectedRouter } from 'react-router-redux';
import "./styles/reset.css";
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById("root")
);
reportWebVitals();
Can confirm upon loading that the "Mint" page loads properly. But if I try and switch the exact path to LandingPage in App.js it'll give that error.
Any help would be greatly appreciated!
I have observed that suddenly CSS path in my project is changed, I am not sure about the reason whether this is a configuration issue or any other, but because of the path CSS is taking too much time to load.
I have already tried to check imports and everything in the code but it seems proper
Please check the below image for path comparison between the new and the backup folder.
New Path:
Old Path
Note: I need the path to be like old where react convert the css to inline, this runs faster.
Below is how I have imported my custom CSS in index.js:
import * as serviceWorker from './serviceWorker';
import React, { Component } from 'react';
import { BrowserRouter, Route } from 'react-router-dom';
import { render } from 'react-dom';
import App from './App';
import './index.css';
import './utilities/animate.css';
//react and redux related library
import { Provider } from 'react-redux';
import store from './redux/store/index';
class Main extends Component {
render() {
return (
<Route path='/' component={App} />
);
}
}
let rootElement = document.getElementById('app');
render(<Provider store={store}>
<BrowserRouter >
<Main />
</BrowserRouter>
</Provider>, rootElement);
serviceWorker.unregister();
I have run npm update and updated few packages, may be some of the packages were corrupted or outdated. This fixed my issue of performance and CSS loading slow.
I have just started using React and have created a new project using create-react-app. I have made a homepage which works. However, I want to add another page to this application. I have a button on the homepage which I want to redirect to another page when clicked. Can someone please give a simple explanation to do this?
I do know that there are other questions that ask this, but they don't seem to apply to create-react-app, or I don't understand them since I am just starting out with React.
Here is my index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import { Route, BrowserRouter as Router } from 'react-router-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
ReactDOM.render((
<Router>
<Route path = "/" component = {App} />
</Router>
), document.getElementById('root'));
registerServiceWorker();
You need to use react-router-dom library. Navigation between pages is really easy in react.
import React from 'react';
import {render} from 'react-dom';
import {Router, Route, hashHistory, BrowserRouter} from 'react-router-dom'
render((
<BrowserRouter basename="/" history={hashHistory}>
{routes()}
</BrowserRouter>
), document.getElementById('app'));
Then in your home page, you can have something similar to below page:
import React, { Component } from 'react';
import { Switch, Route, BrowserRouter, hashHistory } from 'react-router-dom';
import './MainLayout.css';
import ReportNavComponent from './ReportNavComponent';
import ListOfUsers from '../reports/ListOfUsers/ListOfUsers';
import ListOfProviders from '../reports/ListOfProviders/ListOfProviders';
import ListOfDiagnosis from '../reports/ListOfDiagnosis/ListOfDiagnosis';
import ListOfNewPatients from '../reports/ListOfNewPatients/ListOfNewPatients';
import NumberOfAdmissions from '../reports/NumberOfAdmissions/NumberOfAdmissions';
...
<div className="reportContent">
<Switch>
<Route path="/ListOfUsers" component={ListOfUsers} />
<Route path="/ListOfProviders" component={ListOfProviders} />
<Route path="/ListOfDiagnosis" component={ListOfDiagnosis} />
<Route path="/ListOfNewPatients" component={ListOfNewPatients} />
<Route path="/NumberOfAdmissions" component={NumberOfAdmissions} />
<Route component={ListOfUsers} />
</Switch>
</div>
reacter-router-dom is the way to go about routing. But if you have just started with react, why don't start with a boiler-plate project and see how the components and other entities interact?
You should definitely look at davezuko's react-redux starter kit and experiment with it.
