I have wrapped my index.js file to support a Redux Store and React-Router-v4.
However, when I try to run a basic test, I get the following error message:
Invariant Violation: You should not use <Route> or withRouter() outside a <Router>
Here is what my index.js looks like:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import { BrowserRouter } from 'react-router-dom';
import registerServiceWorker from './registerServiceWorker';
// Redux
import { Provider } from 'react-redux';
import store from "./store/index";
ReactDOM.render((
<Provider store={store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>
), document.getElementById('root'));
registerServiceWorker();
and here is my App.js:
import React, { Component } from 'react';
import { ScaleLoader } from 'react-spinners';
import { withRouter } from 'react-router';
import Header from './components/Header';
import Footer from './components/Footer';
import Main from './Main';
import './styles/styles.scss';
// Redux
import { connect } from 'react-redux';
import store from "./store/index";
import { isLoading } from "./actions/index";
class App extends Component {
constructor() {
super();
store.dispatch(isLoading(true));
}
componentDidUpdate(prevProps) {
if (this.props.location.pathname !== prevProps.location.pathname) {
store.dispatch(isLoading(true));
}
}
render() {
return (
<div className='App'>
<Header />
<div className='App__wrapper'>
<div className={'loading-spinner ' + (this.props.isLoading ? null : '--hide-loader')}>
<ScaleLoader
color={'#123abc'}
loading={this.props.isLoading}
/>
</div>
<Main />
</div>
<Footer />
</div>
);
}
}
const mapStateToProps = (state) => ({ isLoading: state.isLoading });
export default withRouter(connect(mapStateToProps)(App));
Since I'm using withRouter to wrap for navigation, is this method discouraged? Should I be setting up withRouter at the index.js level?
Thank you!
Try importing your BrowserRouter like this:
import { BrowserRouter as Router } from 'react-router-dom'
Then replace everywhere it appears BrowserRouter with Router instead.

After updating to react router V6 my component no longer renders:
Trying to render the home component within my app, seems like the router is correctly organized according to React Router V6.
I am able to render the "SubredditAside" component which is located outside of the in the App.js but trying to render the Home component doesnt seem to be working
App.js:
import React from 'react';
import {
BrowserRouter,
Routes,
Route,
Router,
} from "react-router-dom";
import { selectDarkMode } from "../features/Theme/themeSlice";
import { useSelector } from "react-redux";
import './App.css';
import "../features/Theme/theme.css";
import Header from "../features/Header/Header";
import Home from "../features/Home/Home";
import SearchResults from "../features/SearchResults/SearchResults";
import SubredditsAside from "../features/SubredditsAside/SubredditAside";
import Subreddit from "../features/Subreddit/Subreddit";
import NotFoundPage from '../features/NotFoundPage/NotFoundPage';
function App() {
const darkMode = useSelector(selectDarkMode);
return (
<BrowserRouter>
<div id="app-container" className={darkMode ? "dark" : "light"}>
<Header />
<main>
<Routes>
<Route path="/" component={Home}/>
<Route path="/r/:id" component={Subreddit}/>
<Route path="/search/:id" component={SearchResults}/>
<Route component={NotFoundPage} />
</Routes>
</main>
<aside>
<SubredditsAside />
</aside>
</div>
</BrowserRouter>
);
}
export default App;
Home.js
import React, { useEffect } from "react";
import Filters from "../Filters/Filters";
import Post from "../Post/Post";
import PostLoading from "../Post/PostLoading";
import NotFoundPage from "../NotFoundPage/NotFoundPage";
import { AnimatedList } from "react-animated-list";
import { useDispatch, useSelector } from "react-redux";
import {
loadPostsHot,
selectPosts,
selectIsLoading,
selectError,
} from "../../app/appSlice";
import { setCurrentSubreddit } from "../SubredditsAside/SubredditAsideSlice"
import { setCurrentFilter } from "../Filters/filtersSlice";
const Home = ({ match }) => {
const dispatch = useDispatch();
const posts = useSelector(selectPosts);
const isLoading = useSelector(selectIsLoading);
const error = useSelector(selectError);
const currentSubreddit = match.params.id;
useEffect(() => {
dispatch(setCurrentFilter("hot"));
dispatch(setCurrentSubreddit(""));
dispatch(loadPostsHot());
}, [dispatch, currentSubreddit]);
if (error) {
return <NotFoundPage />;
}
return (
<>
<Filters />
{isLoading ? (
<AnimatedList>
<PostLoading />
<PostLoading />
<PostLoading />
</AnimatedList>
) : (
posts.map((post, index) => (
<Post key={index} post={post} postIndex={index} />
))
)}
</>
);
};
export default Home;
Index.js:
import React from 'react';
import { ReactDOM } from 'react';
import { createRoot } from 'react-dom/client';
import { Provider } from 'react-redux';
import { store } from './app/store';
import App from '../src/app/App';
import reportWebVitals from './reportWebVitals';
import './index.css';
import "#fontsource/roboto";
// import "./base.css";
import { BrowserRouter } from 'react-router-dom';
const container = document.getElementById('root');
const root = createRoot(container);
root.render(
<React.StrictMode>
<Provider store={store}>
<App />
</Provider>
</React.StrictMode>
);
I'm trying to configure the react router dom route structure, but apparently my routes are not being recognized within the application
routes/index.tsx
import React from 'react';
import { inject, observer } from 'mobx-react';
import { Routes, Route, Link } from "react-router-dom";
import {
Main,
} from '../scenes';
import { Routes as RoutesPath } from './routing';
const RoutesContainer: React.FC = () => (
<Routes>
<Route path={RoutesPath.MAIN} element={<Main />} />
</Routes>
);
export { Routes };
export default inject('routing')(observer(RoutesContainer));
index.tsx (aplication)
import React from 'react'
import { Provider } from 'mobx-react';
import { render } from 'react-dom'
import './index.css'
import store from './stores';
import { Routes } from './routes';
import { BrowserRouter } from 'react-router-dom';
render(
<Provider rootStore={store}>
<BrowserRouter>
<React.StrictMode>
<Routes />
</React.StrictMode>
</BrowserRouter>
</Provider>,
document.getElementById('root')
)
If I remove my component, and add some text it displays correctly, but with the component it displays a blank screen.
Why my project show Index of folder when build, but when it running, it works
My Index.js
import React from "react";
import ReactDOM from "react-dom";
import { Provider } from "react-redux";
import { createStore } from "redux";
import rootReducer from "./reducers";
import { HashRouter } from "react-router-dom";
import App from "./App";
import "./index.css";
import createBrowserHistory from "history/createBrowserHistory";
const store = createStore(rootReducer);
const history = createBrowserHistory();
ReactDOM.render(
<Provider store={store}>
<HashRouter history={history}>
<App />
</HashRouter>
</Provider>,
document.getElementById("root")
);
My App.js
import React, { Component } from "react";
export default class App extends Component {
render() {
return (
<div>
<h1>ABC</h1>
</div>
);
}
}
When i call my index.html and my bundle.js after build
I have this code, and it is very good working on other environment without webpack.
This is main.js on frontend
import ReactDOM from "react-dom";
import React from "react";
//import { Router, Route, hashHistory } from 'react-router';
import { BrowserRouter, Route } from "react-router-dom";
import App from "./components/App.jsx";
import WizardIndex from "./components/index.js";
ReactDOM.render(
<BrowserRouter>
<App>
<Route path="/signup" component={WizardIndex} />
</App>
</BrowserRouter>,
document.getElementById("mount-point")
);
This is App.jsx
import React from "react";
import { Link } from "react-router-dom";
class App extends React.Component {
render() {
const { children } = this.props;
return (
<div className="App">
<div className="menu-bar">
<div className="menu-item">
<h3>App</h3>
<Link to="/signup">Signup</Link>
</div>
<div className="content">{children}</div>
</div>
</div>
);
}
}
export default App;
And Here I include WizardIndex file index.js
import React from "react";
import ReactDOM from "react-dom";
import { Provider } from "react-redux";
import { Values } from "redux-form-website-template";
import store from "./store";
import showResults from "./showResults";
import WizardForm from "./WizardForm";
class WizardIndex extends React.Component {
render() {
return (
<h1>

I have a very simple project and react router dom is not rendering components. Sometimes it renders the component for first route but then it doesn't render.
Here's the code for App.js:
import React, { Component } from 'react';
import { Provider } from "react-redux";
import {
BrowserRouter as Router,
Route
} from "react-router-dom";
import store from "./store";
import createHistory from 'history/createBrowserHistory';
import { IntroJm } from './components/intro/jm';
import { IntroNfc } from './components/intro/nfc';
import { IntroTxn } from './components/intro/txn';
import './assets/sass/main.scss';
import './static/css/main.scss';
import './static/css/pure.min.scss';
import './App.scss';
let browserHistory = createHistory();
class App extends Component {
componentDidMount() {
browserHistory.push("/intro/jm");
}
render() {
return (
<Provider store={store}>
<div>
<Router>
<div>
<Route path="/intro/jm" component={IntroJm} />
<Route path="/intro/nfc" component={IntroNfc} />
<Route path="/intro/txn" component={IntroTxn} />
</div>
</Router>
</div>
</Provider>
);
}
}
export default App;
All the route components are simple component with a span tag only.
Please help
You can try wrapping your component with WithRouter and then changing the route with this.props.history.push()
Try
import React, { Component } from 'react';
import { Provider } from "react-redux";
import {
BrowserRouter as Router,
Route
} from "react-router-dom";
import {withRouter} 'react-router';
import store from "./store";
import { IntroJm } from './components/intro/jm';
import { IntroNfc } from './components/intro/nfc';
import { IntroTxn } from './components/intro/txn';
import './assets/sass/main.scss';
import './static/css/main.scss';
import './static/css/pure.min.scss';
import './App.scss';
let browserHistory = createHistory();
class App extends Component {
componentDidMount() {
this.props.history.push("/intro/jm");
}
render() {
return (
<Provider store={store}>
<div>
<Router>
<div>
<Route path="/intro/jm" component={IntroJm} />
<Route path="/intro/nfc" component={IntroNfc} />
<Route path="/intro/txn" component={IntroTxn} />
</div>
</Router>
</div>
</Provider>
);
}
}
export default withRouter(App);
