Adding a Router

Introduction:​

Welcome, fellow Code Mastermind! Today, we embark on an exciting journey to enhance our React app by adding routing capabilities. Routing allows us to create dynamic, multi-page applications without the need for full-page refreshes. Buckle up, and let's dive into the world of React Router!

1: What is React Router?​

React Router is a popular library that enables navigation and routing within a React application. It provides a seamless way to create multiple pages while maintaining a single-page app feel. Think of it as a virtual GPS system for your app, guiding users to different views without reloading the entire page.

2: Getting Started​

Before we hit the road, let's set up our project! Make sure you have Node.js and npm installed. If not, visit Node.js' official website and follow their easy installation guide.

Once you have everything set up, create your React app using Create React App (CRA). In your terminal, type:

npx create-react-app my-awesome-app
cd my-awesome-app

Now, we're ready to install React Router. Execute the following command:

npm install react-router-dom

3: Creating Our Routes​

Imagine your app is a fantastic theme park, and each attraction represents a different page. Let's map out our routes accordingly:

  1. Home: The main entrance to our park, where visitors start their journey.
  2. About: An information booth to learn more about our park's history.
  3. Contact: A helpline where visitors can reach out for any queries.
  4. NotFound: A secret portal to another dimension for lost URLs (404 page).

4: Setting Up the Router​

Now that we have our routes planned out, let's integrate React Router into our app. Open the src/App.js file, and let the routing magic begin:

src/App.js
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import Home from './components/Home';
import About from './components/About';
import Contact from './components/Contact';
import NotFound from './components/NotFound';

function App() {
  return (
    <Router>
      <Routes>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
        <Route path="/contact" component={Contact} />
        <Route component={NotFound} />
      </Routes>
    </Router>
  );
}

5: Creating Our Components​

To keep our code organized, let's create separate components for each route we defined earlier. For instance, create Home.js, About.js, Contact.js, and NotFound.js in the src/components folder. Don't forget to sprinkle some code wizardry into each component to make them shine!

6: Linking It All Together​

Now that we have our routes and components set up, we need navigation links for our visitors to explore the park. Update your src/components/Home.js with the following code:

src/components/Home.js
import { Link } from 'react-router-dom';

function Home() {
  return (
    <div>
      <h1>Welcome to Code Mastermind Theme Park!</h1>
      <nav>
        <ul>
          <li>
            <Link to="/">Home</Link>
          </li>
          <li>
            <Link to="/about">About</Link>
          </li>
          <li>
            <Link to="/contact">Contact</Link>
          </li>
        </ul>
      </nav>
    </div>
  );
}
