Introduction to React Router

In this tutorial, we will learn how to use React Router to create a multi-page application. We will cover setting up routes and navigating between pages.

Step 1: Setting up the Project

First, we need to set up a new React project. We can do this by running the following command in our terminal:

npx create-react-app router-app

Step 2: Installing React Router

Next, we need to install React Router. We can do this by running the following command in our terminal:

npm install react-router-dom

Step 3: Creating the Routes

We can create a new component for our routes. We can do this by creating a new file called Routes.js in the src directory:

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

function Routes() {
  return (
    <BrowserRouter>
      <div>
        <nav>
          <ul>
            <li><Link to='/'>Home</Link></li>
            <li><Link to='/about'>About</Link></li>
            <li><Link to='/contact'>Contact</Link></li>
          </ul>
        </nav>
        <Route path='/' exact component={Home} />
        <Route path='/about' component={About} />
        <Route path='/contact' component={Contact} />
      </div>
    </BrowserRouter>
  );
}

export default Routes;

Step 4: Creating the Page Components

We can create new components for our pages. We can do this by creating new files called Home.js, About.js, and Contact.js in the src directory:

// Home.js
import React from 'react';

function Home() {
  return (
    <div>
      <h1>Welcome to the home page!</h1>
    </div>
  );
}

export default Home;

// About.js
import React from 'react';

function About() {
  return (
    <div>
      <h1>Welcome to the about page!</h1>
    </div>
  );
}

export default About;

// Contact.js
import React from 'react';

function Contact() {
  return (
    <div>
      <h1>Welcome to the contact page!</h1>
    </div>
  );
}

  ;
