Routing with no page found(error 404) error handling
Sometimes user types a URL which does not exist in the website and the router fails and shows an error. To solve this problem we create a universal Route component which redirects to Link not found page whenever incorrect URL is passed
Approach:
- Create 3 basic pages where you want to add navigation
- Create a Navbar to handle navigation between the pages
- Create NoPageFound.js file to handle routing for all incorrect routing
- Add a path for non-configured routes which will be redirected to NoPageFound file
the path with ‘*‘ handles all non-configured routes
Example: Add the following code in respective files after removing default styling in App.css
- App.js: This file imports all the components and applies routing to them
- AboutUs.js: This file contains the About Us Page
- ContactUs.js: This file displays the Contact Us Page
- Home.js: This component acts as the home page
- Navbar.js: This component has the Navbar to redirect to all linking pages
- NoPageFound.js: This page is displayed when invalid links are added.
Javascript
// App.js import logo from "./logo.svg"; import { BrowserRouter, Routes, Route } from "react-router-dom"; import "./App.css"; import NavBar from "./components/Navbar"; import Home from "./components/Home"; import AboutUs from "./components/AboutUs"; import ContactUs from "./components/CotactUs"; import NoPageFound from "./components/NoPageFound"; function App() { return ( <div className="App"> <BrowserRouter> <NavBar /> <Routes> <Route exact path="/" element={<Home />} /> <Route exact path="/about" element={<AboutUs />} /> <Route exact path="/contact" element={<ContactUs />} /> <Route path="*" element={<NoPageFound />} /> </Routes> </BrowserRouter> </div> ); } export default App; |
Javascript
// AboutUs.js import React from "react"; function AboutUs() { return ( <div> <h2>w3wiki is a computer science portal for geeks!</h2> Read more about us at : https://www.w3wiki.org/about/ </a> </div> ); } export default AboutUs; |
Javascript
// ContactUs.js import React from "react"; function ContactUs() { return ( <address> You can find us here: <br /> w3wiki <br /> 5th & 6th Floor, Royal Kapsons, A- 118, <br /> Sector- 136, Noida, Uttar Pradesh (201305) </address> ); } export default ContactUs; |
Javascript
// Home.js import React from "react"; function Home() { return <h1>Welcome to the world of Geeks!</h1>; } export default Home; |
Javascript
// Navbar.js import { Link } from "react-router-dom"; export default function NavBar() { return ( <div> <ul className="r"> <li> <Link to="/">Home</Link> </li> <li> <Link to="/about">About Us</Link> </li> <li> <Link to="/contact">Contact Us</Link> </li> </ul> </div> ); } |
Javascript
// NoPageFound.js export default function NoPageFound() { return <h1>Error 404: Page Not Found</h1>; } |
