Routing

In React, routing is most commonly achieved through React Router.

React Router is a third-party library that allow components to be used as routed endpoints within an application. This library comes in three packages:

• react-router: For core functionality
• react-router-native: React Native version
• react-router-dom: Recommended for web applications

Install the newest version with npm:

npm install react-router-dom@latest

The newest version of React Router is v6, which comes with many breaking changes including:

• Using a <Routes /> component instead of a <Switch /> component for <Route /> configuration.
• Using the element attribute instead of component when passing a JSX to a <Link />.

Example

Below, a <BrowserRouter/> (aliased as <Router/>) is used to map the navigation <Link/> components to a <Routes/> component. The <Routes/> renders the appropriate <Route> based on the most specific-matching path among all possible matches.

import Home from './Home';
import About from './About';
import Projects from './Projects';
import Contact from './Contact';

import { BrowserRouter as Router, Routes, Route, Link } from 'react-router-dom';

const App = () => {
  return (
    <div>
      <Router>
        <nav>
          <ul>
            <Routes>
              <Route path="/about" element={<About />} />
              <Route path="/blog" element={<Blog />} />
              <Route path="/contact" element={<Contact />} />
              <Route path="/" element={<Home />} />
            </Routes>
            <li>
              <Link to="/">Home</Link>
            </li>
            <li>
              <Link to="/about">About</Link>
            </li>
            <li>
              <Link to="/projects">Projects</Link>
            </li>
            <li>
              <Link to="/contact">Contact</Link>
            </li>
          </ul>
        </nav>
      </Router>
    </div>
  );
};

const Home = () => {
  return <h2>Home</h2>;
};

const About = () => {
  return <h2>About</h2>;
};

const Projects = () => {
  return <h2>Projects</h2>;
};

const Contact = () => {
  return <h2>Contact</h2>;
};

export default App;
