I have one Navbar in React with the following code
import './App.css';
import { BrowserRouter as Router, Route, Link, Switch } from 'react-router-dom';
import Header from './components/header/Header';
import Home from './components/home/Home';
import About from './components/about/About';
import Accessories from './components/accessories/Accessories';
import Category1 from './components/accessories/categories/Category1';
import Category2 from './components/accessories/categories/Category2';
import Category3 from './components/accessories/categories/Category3';
import Category4 from './components/accessories/categories/Category4';
import Contact from './components/contact/Contact';
import Footer from './components/footer/Footer';
const App = () => {
return (
<div className="App">
<Header />
<Router>
<Switch>
<Route exact path="/">
<Home />
<About />
<Accessories />
<Contact />
</Route>
<Route exact path="/category1">
<Category1 />
</Route>
<Route exact path="/category2">
<Category2 />
</Route>
<Route exact path="/category3">
<Category3 />
</Route>
<Route exact path="/category4">
<Category4 />
</Route>
</Switch>
</Router>
<Footer />
</div>
);
}
export default App;
I can go smoothly from / to /category1, but when I reroute to / from /category1, no rerendering is happening until I refresh the page.
I have no idea what to do now. Thank you for any help in advance
Edited: I just changes all my Links to anchor tags and now they are working but is it a good practice?
<Route exact path="/">
<Home />
<About />
<Accessories />
<Contact />
</Route>
Put the above code after all the routes are being defined and it should work
<Switch>
<Route exact path="/category1">
<Category1 />
</Route>
<Route exact path="/category2">
<Category2 />
</Route>
<Route exact path="/category3">
<Category3 />
</Route>
<Route exact path="/category4">
<Category4 />
</Route>
<Route exact path="/">
<Home />
<About />
<Accessories />
<Contact />
</Route>
</Switch>
The '/' path should be defined at the last after all the paths have been defined
You have to use the element to redirect to other routes. In "/category1", you can use the element to redirect "/" without reloading the page.

I have one problem that I can not understand. I am totally a beginner in ReactJS so I hope you will help me. I made Navigation with React Router and it works, but when I start to render all other components in App.js nothings happened. When I am routing through the navigation bar it is rendering, but on scroll, nothing happened.
This is my App.js without rendering other components that work normally, but when I add something like , it is the same without scroll.
my code :
const App = () => {
return (
<div>
<Router>
<Topbar />
<About />
<Switch>
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
<Route path="/service" component={Service} />
<Route path="/portfolio" component={Portfolio} />
<Route path="/contact" component={Contact} />
</Switch>
</Router>
</div>
);
};
export default App;
You need to use a redirect
1/ import {Redirect} from 'react-router-dom';
2/ Change your Home route to <Route exact path="/home" component={Home} />
3/ Add the redirect (It must be the last route)
<Route exact path="/">
<Redirect to="/home" />
</Route>
Example :
import React from 'react';
import {
BrowserRouter as Router,
Route,
Switch,
Redirect
} from 'react-router-dom';
import Home from './Home';
import About from './About';
import Service from './Service';
import Portfolio from './Portfolio';
import Contact from './Contact';
const App = () => {
return (
<Router>
<Switch>
<Route path="/" component={Home} />
<Route path="/about" component={About} />
<Route path="/service" component={Service} />
<Route path="/portfolio" component={Portfolio} />
<Route path="/contact" component={Contact} />
{/* Redirect */}
<Route exact path="/">
<Redirect to="/home" />
</Route>
</Switch>
</Router>
);
};
export default App;

when ever i click on any of the link it show me " Job category " page

Wrap your switch inside the browser router. More over re arrange your routes as react will render the first matching route.
import App from "./App";
import User from "./components/UserManagment/Users";
import Agents from "./components/UserManagment/Agents";
import Usertable from "./components/Usertable";
import Usertopbar from "./components/Usertopbar";
import { BrowserRouter, Switch, Route } from "react-router-dom";
import UserRole from "./components/UserManagment/UserRole";
import Suppliers from "./components/Contact/Suppliers";
import Group from "./components/Contact/Group";
import Mod from "./components/Model";
import Custom from "./components/Contact/Custom";
import Contactmodel from "./components/Contact/Contactmodel";
import Login from "./components/Rm.live/Login";
import Signup from "./components/Rm.live/Signup";
import Rmtable from "./components/Rm.live/rm/Rmtable";
import Blogin from "./components/Bootstrap/Login";
import RmSkills from "./components/Rm.live/rm/RmSkills";
export const Routes = () => {
return (
<>
<BrowserRouter basename={process.env.PUBLIC_URL}>
<Switch>
<Route path="/agents" component={Agents} exact />
<Route patch="/rmskills" component={RmSkills} exact />
<Route patch="/rmtable" component={Rmtable} exact />
<Route path="/Blogin" component={Blogin} exact />
<Route path="/login" component={Login} />
<Route path="/signup" component={Signup} />
<Route path="/user" component={User} exact />
<Route path="/userrole" component={UserRole} exact />
<Route path="/usertable" component={Usertable} exact />
<Route path="/usertopbar" component={Usertopbar} exact />
<Route path="/mod" component={Mod} exact />
<Route Path="/custom" component={Custom} />
<Route path="/group" component={Group} exact />
<Route Path="/contactmodel" component={Contactmodel} />
<Route path="/suppliers" component={Suppliers} exact />
<Route path="/" component={App} exact />
</Switch>
</BrowserRouter>
</>
);
};
export default Routes;
I'm having a problem regarding using of error page in my react app. The 404 page always shows at the bottom of every page that I render. I'm new to react. I hope someone can help me.
This is my App.js
import {BrowserRouter as Router,Switch,Route} from 'react-router-dom';
import Login from './components/auth/Login';
import Register from './components/auth/Register';
import ErrorPage from './components/ErrorPage';
import Order from './components/Order';
import Navbar from './components/partials/Navbar';
import Footer from './components/partials/Footer';
import Shop from './components/Shop';
import ItemDetails from './components/ItemDetails';
import Cart from './components/Cart';
import Customize from './components/Customize';
const App = () => {
return (
<>
<Router>
<Switch>
<Route exact path='/login'>
<Login />
</Route>
<Route exact path='/register'>
<Register />
</Route>
<div>
<Navbar />
<Route exact path='/'>
<Shop />
</Route>
<Route exact path='/order'>
<Order />
</Route>
<Route exact path='/item/details'>
<ItemDetails />
</Route>
<Route exact path='/cart'>
<Cart />
</Route>
<Route exact path='/customize'>
<Customize />
</Route>
<Route component={ErrorPage} />
</div>
</Switch>
</Router>
<Footer />
</>
);
}
export default App;
I searched about handling error page in react and I see that the order of routes is important but I don't get why I'm still getting the error page even it's in the bottom. Thank you guys.
That's because the switch component returns the first child at the root that meets the path condition. If the path condition doesn't exist it's evaluated as true. In your case you have 3 child Login, Register and the div which will always be evaluated to true. So just move all routes to the root of your switch:
<Router>
<Switch>
<Route exact path='/login'>
<Login />
</Route>
<Route exact path='/register'>
<Register />
</Route>
<div>
<Navbar />
<Switch>
<Route exact path='/'>
<Shop />
</Route>
<Route exact path='/order'>
<Order />
</Route>
<Route exact path='/item/details'>
<ItemDetails />
</Route>
<Route exact path='/cart'>
<Cart />
</Route>
<Route exact path='/customize'>
<Customize />
</Route>
<Route component={ErrorPage} />
</Switch>
</div>
</Switch>
</Router>
I'm trying show Error component if matches not found, but nothing happens - when I choose non-existing route, I see only blank page.
The Main component adds sidebar menu in example and renders all it childes inside in rest.
When all Route componets placed directly inside Switch - all works (including Error).
But in example below, Error component does not render - if route does not match - only blank page.
If Error component placed inside Main, in that case it will be rendered even for existing routes.
import React from 'react';
import { Switch, Route } from "react-router-dom";
import Signin from "../../containers/Signin";
import Signup from "../../containers/Signup";
import Error from "../../containers/Error";
import Courses from "../../containers/Courses";
import Course from "../../containers/Course";
import Quiz from "../../containers/Quiz";
import Header from "../Header";
import "./App.css";
import Library from "../../containers/Library";
import QuizResults from "../../containers/QuizResults";
import Main from "../Main";
import StudentsList from "../../containers/StudentsList";
function App()
{
return (
<div className="App">
<Header isLogged={false}/>
<Switch>
<Route exact path='/' component={Signin} />
<Route path='/signup' component={Signup} />
<Main>
<Route path='/courses' component={Courses} />
<Route path='/course/:id' component={Course} exact/>
<Route path='/quiz' component={Quiz} />
<Route path='/library' component={Library} />
<Route path='/quiz-results' component={QuizResults} />
<Route path='/students' component={StudentsList} />
<Route component={Error} />
</Main>
</Switch>
</div>
);
}
export default App;
So, how to properly render Error component if no matches found?
Try using a wildcard.
<Route path="/*" component={Error} />
Add exact word to the route. And better approach will be to set the Error component name to NotFound or FourZeroFour . It will work then.
<Router>
<Switch>
<Route exact path='/' component={Signin} />
<Route exact path='/signup' component={Signup} />
<Main>
<Route exact path='/courses' component={Courses} />
<Route exact path='/course/:id' component={Course} />
<Route exact path='/quiz' component={Quiz} />
<Route exact path='/library' component={Library} />
<Route exact path='/quiz-results' component={QuizResults} />
<Route exact path='/students' component={StudentsList} />
<Route component={NotFound} />
</Main>
</Switch>
</Router>
Solution for this problem - place another Switch around Route components:
import React from 'react';
import { Switch, Route } from "react-router-dom";
import Signin from "../../containers/Signin";
import Signup from "../../containers/Signup";
import NotFound from "../../containers/NotFound";
import Courses from "../../containers/Courses";
import Course from "../../containers/Course";
import Quiz from "../../containers/Quiz";
import Header from "../Header";
import "./App.css";
import Library from "../../containers/Library";
import QuizResults from "../../containers/QuizResults";
import Main from "../Main";
import StudentsList from "../../containers/StudentsList";
function App()
{
return (
<div className="App">
<Header isLogged={false}/>
<Switch>
<Route exact path='/' component={Signin} />
<Route exact path='/signup' component={Signup} />
<Main>
<Switch>
<Route exact path='/courses' component={Courses} />
<Route exact path='/course/:id' component={Course} />
<Route exact path='/quiz' component={Quiz} />
<Route exact path='/library' component={Library} />
<Route exact path='/quiz-results' component={QuizResults} />
<Route exact path='/students' component={StudentsList} />
<Route path='*' component={NotFound} />
</Switch>
</Main>
</Switch>
</div>
);
}
export default App;
In React Router I have a nested Route
<Route path='about' component={{main: About, header: Header}}>
<Route path='team' component={Team} />
</Route>
So now it shows Team when I go to /about/team.
But how do I set which Component to be seen when I visit /about?
I have tried
<Route path='about' component={{main: About, header: Header}}>
<IndexRoute component={AboutIndex} />
<Route path='team' component={Team} />
</Route>
and
<Route path='about' component={{main: About, header: Header}}>
<Route path='/' component={AboutIndex} />
<Route path='team' component={Team} />
</Route>
but it doesn't work.
My About component looks like this
class About extends React.Component {
render () {
return (
<div>
<div className='row'>
<div className='col-md-9'>
{this.props.children}
</div>
<div className='col-md-3'>
<ul className='nav nav-pills nav-stacked'>
<li className='nav-item'><IndexLink className='nav-link' to='/about' activeClassName='active'>About</IndexLink></li>
<li className='nav-item'><Link className='nav-link' to='/about/team'>Team</Link></li>
</ul>
</div>
</div>
</div>
);
}
}
REACT ROUTER 4 UPDATE
The default route is the one without a path.
import BrowserRouter from 'react-router-dom/BrowserRouter';
import Switch from 'react-router-dom/Switch';
import Route from 'react-router-dom/Route';
<BrowserRouter>
<Switch>
<Route exact path='/about' component={AboutIndex} />
<Route component={AboutIndex} /> // <--- don't add a path for a default route
</Switch>
</BrowserRouter>
If you don't need this object {main: About, header: Header} in your component, then just put AboutIndex in the component attribute. That should work
<Router history={browserHistory}>
<Route path='about' component={AboutIndex}>
<IndexRoute component={AboutIndex} />
<Route path='team' component={Team} />
</Route>
</Router>
If you still need main and header components, just add them in as either parent, child, or sibling components depending on your needs
React Router v6
The route has an attribute index which is used to define the index route as per the docs.
<Route index element={<DefaultPage />} />
Another way to do I found is to use the Navigate component of the react-router-dom package with the index attribute. After the a user navigates to the support route, it will default to the about page in the following example.
<Route path="support/*" element={<Support />}>
<Route index element={<Navigate to="about" replace />} />
<Route path="about" element={<About />} />
<Route path="contact" element={<Contact/>} />
</Route>
