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;

I tried using react router but it doesn't work. I already know that React Router Dom v6 has changed from Switch to Routes but when I run the program it just shows a blank screen. Does anyone know how to fix this? Here is my code:
App.js
'''
import React, {Component} from "react";
import { BrowserRouter as Router } from "react-router-dom";
import { render } from "react-dom";
import HomePage from "./HomePage";
export default class App extends Component{
render() {
return (
<Router>
<div>
<HomePage />
</div>
</Router>
);
}
}
const appDiv = document.getElementById("app");
render(<App />,appDiv);
'''
HomePage.js
'''
import React,{Component} from 'react';
import RoomJoinPage from "./RoomJoinPage";
import CreateRoomPage from "./CreateRoomPage";
import { BrowserRouter as Router ,
Routes ,
Route ,
} from "react-router-dom"
export default class HomePage extends Component{
render () {
return (
<Router>
<Routes>
<Route path='/'>
<p>This is Home Page</p>
</Route>
<Route path='/join' element={<RoomJoinPage />} />
<Route path='/create' element={<CreateRoomPage />} />
</Routes>
</Router>
);
}
}
'''
The error is that "You cannot render a Router inside another Router " occurs when we have 2 Router components in the same React application.
So if u see u are calling in App.js and when u call Homepage from app.js it renders again. Thats why everything becomes blank.
and avoid using p tag inside render function in homepage.js
Try doing this:
**App.js**
import React, {Component} from "react";
import { BrowserRouter as Router } from "react-router-dom";
import { render } from "react-dom";
import HomePage from "./HomePage";
export default class App extends Component{
render() {
return (
<div>
<HomePage />
</div>
);
}
}
const appDiv = document.getElementById("app");
render(<App />,appDiv);
**Homepage.js**
import React,{Component} from 'react';
import RoomJoinPage from "./RoomJoinPage";
import CreateRoomPage from "./CreateRoomPage";
import { BrowserRouter as Router ,
Routes ,
Route ,
} from "react-router-dom"
export default class HomePage extends Component{
render () {
return (
<Router>
<Routes>
<Route path='/'>
</Route>
<Route path='/join' element={<RoomJoinPage />} />
<Route path='/create' element={<CreateRoomPage />} />
</Routes>
</Router>
);
}
}
I am creating a project using MERN stack.In my App.js I imported some react component but while I run it shows a blank White screen.
App.js
import React from "react";
import "bootstrap/dist/css/bootstrap.min.css";
import { BrowserRouter as Router, Route} from "react-router-dom";
import Navbar from "./components/navbar"
import CreateUser from "./components/create-user";
function App() {
return (
<Router>
<div className="container">
<Route path="/" component={Navbar} />
<br/>
<Route path="/user" component={CreateUser} />
</div>
</Router>
);
}
export default App;
navbar.js
import React, { Component } from 'react';
// import { Link } from 'react-router-dom';
export default class Navbar extends Component {
render() {
return (
<h1>Pantha</h1>
);
}
}
I'm trying to separate routes into their own file, but they seem to be always rendered, even if I've added exact to the path.
Home route - home.js:
import React from 'react';
import { BrowserRouter as Route } from 'react-router-dom';
import { HomePageView } from 'components'
const HomeRoute = () => (
<Route exact path='/home'>
<HomePageContainer />
</Route>
)
export default HomeRoute;
HomePageView.js:
import React from 'react';
class HomePageView extends React.Component {
render() {
return (
<div>Some text here</div>
)
}
}
export default HomePageView;
index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import HomeRoute from 'routes/home'
import * as serviceWorker from './serviceWorker';
ReactDOM.render(
<Router>
<HomeRoute />
</Router>,
document.getElementById('root')
);
The problem is that it renders the HomePageView component on any path and I don't understand why this happens because it works as expected if I replace <HomeRoute /> from index.js with:
<Route exact path='/home'>
<HomePageContainer />
</Route>
I haven't tested this myself, but isn't the problem that you are importing BrowserRouter as Route in your home.js?
The file would looks like this when rendered:
<BrowserRouter>
<BrowserRouter>
<HomePageContainer/>
<BrowserRouter/>
<BrowserRouter/>
You need to import route from react-router-rom like this import { Route } from "react-router-dom";
"as" in import is an alias, not what is imported.
Fixed home.js file:
import React from 'react';
import { Route } from "react-router-dom";
import { HomePageView } from 'components'
const HomeRoute = () => (
<Route exact path='/home'>
<HomePageContainer />
</Route>
)
export default HomeRoute;
I am building a single page web app based on react routing where I want to Hide current component before rendering the next component that is supposed to render after clicking on Navlink just like <a href="someLink"> in html. However, my current component doesn't disappear and the next component renders on the same page next to the current component.
my code for app.js (Main file where parent class renders)
import React from 'react';
import {Parent} from './Parent';
import { BrowserRouter as Router, Route, NavLink} from 'react-router-dom';
function App() {
return (
<div className="App">
<header className="App-header">
<Router>
<NavLink to="/Edit">Edit</NavLink>
<Route path="/Edit" component={Edit}/>
</Router>
</header>
</div>
);
}
export default App;
Here is my code for parent.js -
import React from 'react';
import {Child} from './Child';
import { BrowserRouter as Router, Route, NavLink} from 'react-router-dom';
class Parent extends React.Component{
constructor(props) {
super(props);
}
render(){
return(
<div>
<p>Parent Render</p>
<Router>
<NavLink to="/Parent/Child">Child</NavLink>
<Route path="/Parent/Child" component={Child}/>
</Router>
)
}
}
export {Parent}
Child.js
import React from 'react';
class Child extends React.Component{
constructor(props) {
super(props);
}
render(){
return(
<div>
Child Render
</div>
)}
}
export{Child}
There is no problem in app.js. The problem is that when child navlink is clicked, parent does not disappear
I think the best way to approach it would be to wrap your App.js component with BrowserRouter inside your index.js file like this.
//index.js
import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import { BrowserRouter as Router } from "react-router-dom";
ReactDOM.render(
<React.StrictMode>
<Router>
<App />
</Router>
</React.StrictMode>,
document.getElementById("root")
);
And subsequently, you can update your App.js component with all the routes you desire to have by wrapping all the components within the Route component like this.
//App.js
import React from "react";
import { Parent } from "./Parent";
import { BrowserRouter as Router, Route, NavLink } from "react-router-dom";
import Home './Home'
import Edit from './Edit'
import Parent from './Parent'
function App() {
return (
<div className="App">
<Switch>
<Route exact path="/" component={Home} />
<Route path="/Edit" component={Edit} />
<Route path="/parent" component={Parent} />
</Switch>
</div>
);
}
export default App;
Now you don't have to wrap your child components with <Router />, you can create as many <Routes /> in App.js and use <Link /> to navigate to that links.
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.
