property 'pathname' undefined in React Routers - javascript

I am following a tutorial on youtube on building a landing page, but I got stuck on this phase.
Uncaught TypeError: Cannot read property 'pathname' of undefined at new Router
Here is the code:
import ReactDOM from "react-dom";
import App from "./App";
import { BrowserRouter as Router } from "react-router-dom";
import * as serviceWorker from "./serviceWorker";
ReactDOM.render(
<Router>
<App />
</Router>,
document.getElementById("root")
);
serviceWorker.unregister();
The tutorial I am following is using react-router version 5.0.1
Also here is my App.js code that is being used in index.js:
import "./css/App.css";
import { Switch, Route } from "react-router-dom";
import Main from "./pages";
function App() {
return (
<div>
<Switch>
<Route path="/" component={Main} />
</Switch>
</div>
);
}
export default App;
Added Main.js code
import Header from "../components/Header";
class Main extends Component {
render() {
return (
<div>
<Header />
</div>
);
}
}
export default Main;
I tried searching for changes but was unsuccessful in finding a solution that worked.

Text not displayed in React using Routes

I am fairly new to using react and been following a couple of tutorials on YT, I have ran into a problem with one of them. I copied everything line by line, but my text on 'Home' and 'Login' doesnt display! I get no errors, but the page remains blank.
here is App.js
import React from 'react'
import { Routes, Route, useNavigate } from 'react-router-dom';
import Login from './components/Login';
import Home from './container/Home';
const App = () => {
return (
<Routes>
<Route path="login" element={<Login />} />
<Route path="/*" element={<Home />} />
</Routes>
);
};
export default App;
Also the index.js file:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import App from './App';
import './index.css';
ReactDOM.render(
<Router>
<App />
</Router>,
document.getElementById('root'),
);
**Then Login.jsx
**
import React from 'react';
const Login = () => {
return (
<div>
Login
</div>
);
};
export default Login;
Finally Home.jsx
import React from 'react';``your text``
const Home = () => {
return (
<div>
Home
</div>
);
};
export default Home;
I know I am missing something, but I cant seem to find it! Any and all help is very much appreciated!
Tried to see if I am using on old version of the BroswerROuter/Routes in React, but I have very little knowledge to see the difference just yet!

Routing returns white page in React.js

I'm trying to set up routing but for some reason, it returns a blank page and renders nothing.
I'm using router version 6.3.0
// index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from "react-router-dom";
import './index.css';
import App from './App';
ReactDOM.render(
<React.StrictMode>
<BrowserRouter><App /></BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);
// --------------------------------------------- //
// App.js
import React, { Component, Fragment } from "react";
import { Route } from "react-router-dom";
import Header from "./components/Landing/Header"
import Landing from "./components/Landing/Landing";
import Footer from "./components/Landing/Footer";
class App extends Component {
render() {
return (
<Fragment>
<Header />
<Route path="/landing">
<Landing />
</Route>
<Footer />
</Fragment>
);
}
}
export default App;
// --------------------------------------------- //
// Landing.js
import Body from './Body'
function Landing(props) {
return (
<Body>
<div className="Landing">
Landing Context
</div>
</Body>
)
}
export default Landing;
So when I visit http://localhost:3000/landing nothing is rendered, and when I try http://localhost:3000 nothing is rendered either.
If I remove the <Route></Route> part in App.js, it renders, but on any URL. What do I miss?
As the OP is using react-router-dom v6
Instead of children, it is expecting element props to render the component.
https://reactrouter.com/docs/en/v6/getting-started/overview#configuring-routes
In app.js wrap your route in router like this
import React, { Component, Fragment } from "react";
import { Router, Route } from "react-router-dom";
import Header from "./components/Landing/Header"
import Landing from "./components/Landing/Landing";
import Footer from "./components/Landing/Footer";
class App extends Component {
render() {
return (
<Fragment>
<Header />
<Router>
<Route path="/landing">
<Landing />
</Route>
</Router>
<Footer />
</Fragment>
);
}
}
export default App;
react-router v6 has some breaking changes, it replaced Switch with Routes component:
/ index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from "react-router-dom";
import './index.css';
import App from './App';
ReactDOM.render(
<React.StrictMode>
<BrowserRouter><App /></BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);
// --------------------------------------------- //
// App.js
import React, { Component, Fragment } from "react";
import { Routes, Route } from "react-router-dom";
import Header from "./components/Landing/Header"
import Landing from "./components/Landing/Landing";
import Footer from "./components/Landing/Footer";
class App extends Component {
render() {
return (
<Fragment>
<Header />
<Routes>
<Route path="/landing" element={<Landing />}/>
</Routes>
<Footer />
</Fragment>
);
}
}
export default App;
https://reactrouter.com/docs/en/v6/getting-started/overview
If your are using react-router version < 6 then you have to add Switch element imported from react-router-dom above your Route Element -
// App.js
import React, { Component, Fragment } from "react";
import { Route, Switch } from "react-router-dom";
class App extends Component {
render() {
return (
<Fragment>
<Switch>
<Route path="/landing">
<div>On LAnding Page</div>
</Route>
</Switch>
</Fragment>
);
}
}
export default App;
And if you are using react-router > 6 then you have to replace Switch with Routes and place your component you want to render inside element property of Route . The code should be similar to following -
// App.js
import React, { Component, Fragment } from "react";
import { Route, Routes } from "react-router-dom";
class App extends Component {
render() {
return (
<Fragment>
<Routes>
<Route path="/landing"
element={<div>On Landing Page</div>}>
</Route>
</Routes>
</Fragment>
);
}
}
export default App;

why is my router not working in react - React.js

Can anyone tell me why my router is not working, I didn’t do anything to complicated with my app its one one page and I tried to add a router in app.js that has a link to my home page and every time i add router everything disappears from my app its just a white screen.
app.js
import "aos/dist/aos.css";
import { BrowserRouter as Router, Route, Routes} from "react-router-dom";
import Home from "./components/Home";
function App() {
return (
<div className="App">
<h1>Welcome to React Router!</h1>
<Routes>
<Route path="/" element={<Home />} />
</Routes>
</div>
);
}
export default App;
Home.js
import React from 'react'
function Home() {
return (
<div>Home</div>
)
}
export default Home
index.js
import * as React from "react";
import * as ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import "./index.css";
import App from "./App";
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.getElementById("root")
);
Try using Switch instead of Routes and you also don't have to use triangular brackets in element
import Home from './components/Home';
import { Route, Switch } from 'react-router';
<Switch>
<Route path="/" element={Home} />
</Switch>
If you want all path begin with / go to your home page, you can change like this: <Route path="/*" element={} />

React-Router routing to class components

I am trying to route to a class component but it gives me an error. When I change the component to a functional component, the routing works. How do I route to class components?
I am new to using react-router. I first had a functional component to route to. But once I realized the component needs to be a class, I changed it to a class and now the routing shows
"Cannot GET /explore/words'.
index.js
import React from "react";
import { render } from "react-dom";
import { BrowserRouter } from "react-router-dom";
import App from "./App";
render(
<BrowserRouter>
<App />
</BrowserRouter>,
document.querySelector("#root")
);
App.js
import React from "react";
import { BrowserRouter as Router, Route, Switch } from "react-router-dom";
import HomePage from "./pages/HomePage";
import ExplorePage from "./pages/ExplorePage";
function App() {
return (
<Router>
<div>
<header>
<nav>Course Finder</nav>
</header>
<Route path="/" component={HomePage} />
<Route path="/explore/:campus" component={ExplorePage} />
</div>
</Router>
);
}
export default App;
Explore.js
import React, { Component } from "react";
class ExplorePage extends Component {
render() {
return (
<div>
<h1>Explore</h1>
</div>
);
}
}
export default ExplorePage;
Expected result was to see the 'Explore' heading.
I get 'Cannot GET /explore/words' instead.
This is working fine, all you have to do is add /explore/one to url to see the route working.

React Router always says no route even when they are set up

I've just started with Meteor and React and most everything I've seen for routers points me to react-router. I've pulled some code from the simple-todos branch and set up a "/" route but keep getting the error router.js:347 There is no route for the path: /. The page shows the content but I don't understand why this error is showing. I've tried Googling for answers and I can't find anything to help me solve this. I've also tried creating <Link /> elements to have links send me to other pages and that doesn't work either.
Here is my code:
Routes.jsx
import React from 'react';
import { Router, Route, browserHistory, IndexRoute } from 'react-router';
import { render } from 'react-dom';
import Home from '../../ui/layouts/Home.jsx';
import SignUpPage from '../../ui/pages/SignUpPage.jsx';
export const renderRoutes = () => (
<Router history={browserHistory}>
<Route path="/" component={Home} />
</Router>
);
Home.jsx
import React, { Component, PropTypes } from 'react';
import ReactDOM from 'react-dom';
import { Meteor } from 'meteor/meteor';
import { RouteHandler } from 'react-router';
import NavBase from '../components/nav/NavBase.jsx';
import Splash from '../components/home/Splash.jsx';
import Snapshot from '../components/home/Snapshot.jsx';
import FooterCTA from '../components/home/FooterCTA.jsx';
import JoinModal from '../components/accounts/JoinModal.jsx';
import LogInModal from '../components/accounts/LogInModal.jsx';
import '../stylesheets/bootstrap.min.css';
import '../stylesheets/style.css';
export default class Home extends Component {
render() {
return (
<div>
<NavBase />
<Splash />
<Snapshot />
<FooterCTA />
<LogInModal />
{this.props.children}
</div>
)
}
}
Home.propTypes = {
currentUser: React.PropTypes.object,
children: React.PropTypes.element,
};
main.jsx
import { Meteor } from 'meteor/meteor';
import { render } from 'react-dom';
import { renderRoutes } from '../imports/startup/client/routes.jsx';
Meteor.startup(() => {
render(renderRoutes(), document.getElementById('app'));
});
Any help with this would be greatly appreciated! Been stuck for a while now and would like to be able to move on.
It looks like you have declared Home as your App layout, then you would have your routes below like this:
<Router history={browserHistory}>
<Route path="/" component={App}>
<IndexRoute component={Home}/>
<Route path="/another" component={Another}/>
</Route>
</Router>
