In this article, we’ll dive deep into the world of React Router 6.4, exploring its features, benefits, and best practices. By the end of this guide, you’ll be well-equipped to tame even the most complex routing systems.

What’s New in React Router 6.4?

React Router 6.4 brings a slew of exciting features and improvements to the table. Some of the most notable updates include:

• Improved Performance**: React Router 6.4 boasts significant performance enhancements, making it faster and more efficient than its predecessors.
• Simplified API**: The new version introduces a more intuitive and streamlined API, making it easier to learn and use.
• Better Support for Server-Side Rendering**: React Router 6.4 provides improved support for server-side rendering, allowing for faster and more efficient rendering of your app.

Getting Started with React Router 6.4

To get started with React Router 6.4, you’ll need to install it via npm or yarn:

npm install react-router-dom@6.4.0

or

yarn add react-router-dom@6.4.0

Once installed, import the BrowserRouter component and wrap your app with it:

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import App from './App';

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById('root')
);

Basic Routing with React Router 6.4

Now that we have React Router 6.4 set up, let’s create a simple routing system. We’ll start by creating a few components:

// Home.js
export function Home() {
  return <h1>Welcome to the Home Page!</h1>
}

// About.js
export function About() {
  return <h1>About Us</h1>
}

// Contact.js
export function Contact() {
  return <h1>Get in Touch</h1>
}

Next, we’ll define our routes using the Route component:

import { Route, Link } from 'react-router-dom';
import Home from './Home';
import About from './About';
import Contact from './Contact';

function App() {
  return (
    <div>
      <h1>Main Application</h1>
      <ul>
        <li><Link to="/">Home</Link></li>
        <li><Link to="/about">About</Link></li>
        <li><Link to="/contact">Contact</Link></li>
      </ul>
      <Route path="/" element=<Home /> />
      <Route path="/about" element=<About /> />
      <Route path="/contact" element=<Contact /> />
    </div>
  );
}

Route Parameters and Query Strings

In many cases, you’ll need to pass parameters or query strings to your routes. React Router 6.4 makes this easy using route parameters and the useParams hook:

import { useParams } from 'react-router-dom';

function User() {
  const params = useParams();
  return <h1>Hello, {params.username}!</h1>;
}

function App() {
  return (
    <div>
      <Route path="/users/:username" element=<User /> />
    </div>
  );
}

In this example, the User component receives the username parameter from the route. You can access query strings using the useLocation hook:

import { useLocation } from 'react-router-dom';

function Search() {
  const location = useLocation();
  const query = new URLSearchParams(location.search);
  const term = query.get('term');
  return <h1>Searching for {term}</h1>;
}

function App() {
  return (
    <div>
      <Route path="/search" element=<Search /> />
    </div>
  );
}

Nesting Routes and Layouts

In larger applications, you’ll often need to nest routes and layouts to create a more organized and reusable structure. React Router 6.4 makes this easy using the Outlet component:

import { Outlet } from 'react-router-dom';

function Dashboard() {
  return (
    <div>
      <h1>Dashboard</h1>
      <Outlet />
    </div>
  );
}

function App() {
  return (
    <div>
      <Route path="/dashboard" element=<Dashboard>
        <Route path="users" element=<UserList /> />
        <Route path="settings" element=<Settings /> />
      </Route>
    </div>
  );
}

404 Pages and Route Hooks

Sometimes, you’ll want to handle cases where a route doesn’t exist or an error occurs. React Router 6.4 provides a NotFound component and route hooks to help you achieve this:

import { Routes, Route, Navigate } from 'react-router-dom';

function NotFound() {
  return <h1>Page Not Found</h1>;
}

function App() {
  return (
    <div>
      <Routes>
        <Route path="/" element=<Home /> />
        <Route path="*" element=<NotFound /> />
      </Routes>
    </div>
  );
}

In this example, the NotFound component is rendered when a non-existent route is accessed. You can also use route hooks to execute code before or after a route is rendered:

import { useRouteError } from 'react-router-dom';

function App() {
  return (
    <div>
      <Routes>
        <Route path="/" element=<Home /> />
        <Route path="*" element=<NotFound /> errorElement=<ErrorBoundary /> />
      </Routes>
    </div>
  );
}

function ErrorBoundary() {
  const error = useRouteError();
  return <h1>Error: {error.message}</h1>;
}
