Why React routing not working in component? - javascript

I'm working on a React web application using React router.
In my App.js file i have imported header and home component.
In home component i have 2 components called Onlinebanks and Creditcard that i imported from online-banks.js and creditcard.js files.
When the user clicks link buttons in home.js component, the Onlinebanks and Creditcard components should render.
Instead i am getting an error called Error: Invariant failed: You should not use < Link> outside a < Router>.
Why it's not working?
INDEX.JS
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
ReactDOM.render(<App />, document.getElementById('root'));
APP.JS
import React, { Component } from 'react';
import './App.css';
import Header from './components/header';
import Home from './components/home';
class Routes extends Component {
constructor(props){
super(props);
this.state = {
};
}
render(){
return (
<div className="wrapper">
<Header/>
<Home/>
</div>
);
}
}
export default Routes;
HOME.JS
import React from 'react';
import { Route, Switch, Link } from 'react-router-dom';
import Onlinebanks from './online-banks';
import Creditcard from './creditcard';
const Home = (props) => {
return (
<div className="section">
<div className="main-page">
<div className="tab-container">
<div className="tab-btns">
<Link to="/">
<div className="online-bank-btn">
Online pangad
</div>
</Link>
<Link to="/creditcard">
<div className="creditcard-btn">
Krediitkaart
</div>
</Link>
</div>
<Switch>
<Route path="/" exact component={Onlinebanks}/>
<Route path="/creditcard" exact component={Creditcard}/>
</Switch>
</div>
</div>
</div>
)
}
export default Home;
ONLINE-BANKS.JS
import React from 'react';
const Onlinebanks = (props) => {
return (
<div className="banks-container">
<input type="button" value="Pay" className="pay-btn" id="online-banks-pay"></input>
</div>
)
}
export default Onlinebanks;
CREDITCARD.JS
import React from 'react';
const Creditcard = (props) => {
return (
<div className="Creditcard-container">
<input type="button" value="Pay" className="pay-btn" id="creditcard-pay"></input>
</div>
)
}
export default Creditcard;

I don't see anywhere in your code where you imported BrowserRouter from react-router-dom which should wrap all the other components rendered by your top level componet (app.js) or entirely wrap the app component. so, first import { BrowserRouter as Router } from "react-router-dom" in index.js, then wrap App component with Router as follows
ReactDOM.render(<Router> <App /> </Router>, document.getElementById("root"));
alternatively you can wrap the retun statment in app.js with Router as follows after importing BrowserRouter as Router
return (
<Router>
<div className="wrapper">
<Header/>
<Home/>
</div>
</Router>
);

<Router> is an HOC component, so you need to use it at the top most level possible. Suggestion would be to create a separate Router component and use it within App.js file above div tag
<CustomRouter>
<div className="wrapper">
<Header/>
<Home/>
</div>
</CustomRouter>

you need to better understand how react-router-dom works.
visit here for complete routing guide react-router-dom
i found some major missings in your app.js file.
import {
BrowserRouter as Router,
Switch,
Route,
Link
} from "react-router-dom";
<Switch>
<Route exact path="/">
<Home />
</Route>
<Route path="/about">
<About />
</Route>
<Route path="/dashboard">
<Dashboard />
</Route>
</Switch>
i don't see this method in your app.js .

component is not render, problems with react-router

I'm having a problem with react-route. The NoteList component is not rendering.
app.js
import { BrowserRouter as Router, Routes } from 'react-router-dom';
import logoNotes from './img/logoNotes.png';
import NoteList from './components/NoteList/NoteList';
import './App.css';
function App() {
return (
<Router>
<div className='aplication-notes'>
<div className='notes-logo-container'>
<img src={logoNotes} className='notes-logo' alt='logo' />
</div>
<div className='note-list'>
<h1> my notes</h1>
<br></br>
<Routes
path='/src/components/NoteList/NoteList'
element={<NoteList />}
/>
</div>
</div>
</Router>
);
}
export default App;
I can see the div and h1 that is in the app.js file but not the Notelist component.
How can I solve this problem?
The Routes component is only responsible for wrapping Route components and handles the path matching duties. It doesn't take path or element props. These belong to the Route component.
Import the Route component and render the NoteList component by the Route and wrap the Route with Routes.
Example:
import {
BrowserRouter as Router,
Routes
Route // <-- import
} from 'react-router-dom';
import logoNotes from './img/logoNotes.png';
import NoteList from './components/NoteList/NoteList';
import './App.css';
function App() {
return (
<Router>
<div className='aplication-notes'>
<div className='notes-logo-container'>
<img src={logoNotes} className='notes-logo' alt='logo' />
</div>
<div className='note-list'>
<h1> my notes</h1>
<br />
<Routes> // <-- wrap Route components
<Route // <-- Route renders content
path="/src/components/NoteList/NoteList"
element={<NoteList />}
/>
</Routes>
</div>
</div>
</Router>
);
}
export default App;
Now when you navigate to "/src/components/NoteList/NoteList" in the browser you should see the UI rendered as well as the NoteList component.

You should never have more than one router in your app

You cannot render a inside another . You should never have more than one in your app.
Why am I having this issue? I have checked my code and I dont have a Router inside another Router. In fact, i only have one router on my app.
This is the component:
import React from 'react';
import { BrowserRouter, Route, Routes } from "react-router-dom";
import Portfolio from '../pages/Portfolio';
function Menu()
{
return (
<BrowserRouter>
<Routes>
<Route path="/" element={<Portfolio />} />
</Routes>
</BrowserRouter>
);
};
export default Menu;
And I call it from this component:
import React from 'react';
import AboutMe from '../components/AboutMe';
import Header from '../components/Header';
import Menu from '../components/Menu';
import Particle from '../components/Particle';
import Services from '../components/Services';
import Skills from '../components/Skills';
function Portfolio()
{
return (
<React.StrictMode>
<Particle />
<Menu />
<Header />
<div className='d-flex flex-column mt-5' id='about-me-services'>
<div><AboutMe /> </div>
<div><Services /> </div>
</div>
<Skills />
</React.StrictMode>
);
}
export default Portfolio;
Thanks for your help :)
Finally, Menu contains a Portfolio, which contains a Menu, which contains a Portfolio, which contains... etc. as super said. Thanks for your help

Routing not working with react-router-dom

I'm working on one of my friend's half-built React Project. I'm trying to route my react-app with react-router-dom. The components inside the <switch> are not working. Here's my
App.js
import React from 'react';
import Header from './components/Header';
import Main from './components/Main';
import Footer from './components/Footer';
import ProcessInput from './components/ProcessInput';
// Import react-router-dom
import { BrowserRouter as Router, Switch, Route} from 'react-router-dom';
function App() {
return(
<Router>
<div className="App">
<Header />
<Switch>
<Route path="/" exact component={Main} />
<Route path="/process" component={ProcessInput} />
</Switch>
<Footer />
</div>
</Router>
);
}
export default App;
Main.js
import React from 'react';
import Slider from './Slider';
import Card1 from './Card1';
import Card2 from './Card2';
import Prompt from './Prompt';
class Main extends React.Component {
render() {
return (
<div>
<main>
<Slider />
<Card1 />
<Card2 />
<Prompt />
</main>
</div>
)
}
}
export default Main;
The <Header /> and <Footer /> which are outside the <Switch> are showing anyways as intended. But, I want the Main component to be loaded as a root component (Launcher).
There are no errors on the console.
Please help me get to know what am I doing wrong. Thanks in advance :)
<Route path="/" exact>
<Main/>
</Route>
<Route path="/process"><ProcessInput/>
</Route>
This is the old way to do it. You can try this

Why isn't my navigation bar rendering in React?

This is the code I have, I believe I have imported everything correctly, I am using React mdl to style it and copied and pasted the navbar code.
I also installed react dom router correctly, the individual pages display but the navbar itself doesn't on the landing page.
Can anyone help me? Thanks
App.js
import React, { Component } from "react";
import "./App.css";
import { Layout, Header, Navigation, Drawer, Content } from "react-mdl";
import Earth from "./earth.jpg";
import Main from "./components/main";
import { Link } from "react-router-dom";
class App extends Component {
render() {
return (
<div style={{ height: "300px", position: "relative" }}>
<Layout style={{ background: "src{Earth} center / cover" }}>
<Header transparent title="Title" style={{ color: "white" }}>
<Navigation>
Link
Link
Link
Link
</Navigation>
</Header>
<Drawer title="Title">
<Navigation>
<Link to="/aboutme">About Us</Link>
<Link to="/projects">Projects</Link>
<Link to="/resume">Resume</Link>
<Link to="/contact">Contact</Link>
</Navigation>
</Drawer>
<Content>
<div className="page-content">
<Main />
</div>
</Content>
</Layout>
</div>
);
}
}
export default App;
main.js
import React from 'react';
import { Switch, Route} from 'react-router-dom';
import LandingPage from './landingpage';
import AboutMe from './aboutme';
import Contact from './contact';
import Projects from './projects';
import Resume from './resume';
const Main = () => (
<Switch>
<Route exact path="/" component = {LandingPage} />
<Route path="/aboutme" component = {AboutMe} />
<Route path="/contact" component = {Contact} />
<Route path="/projects" component = {Projects} />
<Route path="/resume" component = {Resume} />
</Switch>
)
export default Main;
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import 'react-mdl/extra/material.css';
import 'react-mdl/extra/material.js';
import { BrowserRouter } from 'react-router-dom';
ReactDOM.render(
<BrowserRouter>
<App />
</BrowserRouter>
, document.getElementById('root'));
serviceWorker.unregister();
You need to wrap your App component with BrowserRouter from react-router-dom.
You can do this inside you App component, or better in index.js like this:
import { BrowserRouter } from "react-router-dom";
ReactDOM.render(<BrowserRouter><App/></BrowserRouter>, rootElement);

Render a sub route in react router v4

Before I begin I have been on the https://reacttraining.com/react-router/web/guides/quick-start to grasp the idea of how the react router works. I have created a simple 3 page site in react and I want to create a list which will allow me to show some nested components. Whilst the examples on reacttraining.com nicely work on in a singles js file. I have my site split over 3 js files:
APP.JS
import React, {Component} from 'react';
import {
BrowserRouter as Router,
Route,
Link
} from 'react-router-dom';
import {Home} from './Home';
import {User} from './User';
import {Artwork} from './artwork'
import {Header} from './header';
class App extends Component {
render(){
return (
<Router>
<div className="container">
<div className="row">
<div className="col-xs-10 col-xs-offset-1">
<Header />
</div>
</div>
<hr/>
<div className="row">
<div className="col-xs-10 col-xs-offset-1">
<Route path="/" exact component={Home}/>
<Route path="/home" exact component={Home}/>
<Route path="/user" component={User}/>
</div>
</div>
</div>
</Router>
);
}
}
export default App;
USER.JS Edited on 28/03/2017
import React, {Component} from 'react';
import {Artwork} from './artwork';
import {Route, Link} from 'react-router-dom';
export class User extends Component {
render() {
return (
<div className="row">
<div className="col-md-4">
<h3>The User Page</h3>
<p>User ID:</p>
<li><Link to="/user/artwork">Artwork</Link></li>
</div>
<div className="col-md-8">
<Route path="/user/artwork" component={Artwork}/>
</div>
</div>
);
}
}
export default User;
ARTWORK.JS
import React, {Component} from 'react';
export class Art extends Component {
render(){
return (
<div>
<h3>Art</h3>
</div>
);
}
}
export default Art;
The issue that I am having is that whilst i can navigate through to my top level menu items (Home and User) I can not access the artwork component on the the user page. when the artwork button is pressed my user component is removed.
If you're looking at the basic example on react-training, you'll notice that the "child" Route in the Topics component has ${match.url}/:topicId as the path:
<Route path={`${match.url}/:topicId`} component={Topic}/>
This is basically turning it into topics/:topicId which is needed because the top most component wouldn't know what to do with just :topicId.
Likewise, in your situation, your App.js doesn't know what to do with /artwork so it doesn't render anything. If you change your Route path and Link to in User.js to /user/artwork it should start working as desired.
To make your User component more composable/reusable, you'd want to do the same thing as react training and use the passed in match.url on the props.
