Step-by-Step : Converting an HTML Website to ReactJS

Converting a static HTML website into a dynamic ReactJS application allows for better scalability, maintainability, and performance. Below is a detailed step-by-step guide on how to achieve this transformation.

HTML to ReactJS Conversion Process

Step 1: Set Up Your React Environment

Before starting the conversion, ensure you have Node.js installed on your system. If not, download and install it from Node.js official website.

1.1 Install Node.js and npm

To check if Node.js and npm are installed, run: If they are not installed, download and install them.

node -v 
npm -v

1.2 Create a React App

Use Create React App (CRA) to set up the project:

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

Alternatively, if you prefer Vite for better performance:

npm create vite@latest my-react-app --template react
cd my-react-app
npm install

Step 2: Organize Your Existing HTML Files

2.1 Structure Your HTML Website

Your existing HTML site will typically consist of:

  • index.html
  • style.css
  • script.js

Additional assets like images, fonts, etc. Move these assets into the public and src folders of your React project.

2.2 Move Static Assets

  • Place global assets (images, fonts, etc.) inside the public folder.
  • Move reusable CSS files inside src/assets/css/.

Step 3: Break Down HTML into Components

React works with reusable components, so you’ll need to break the HTML into small, manageable React components.

3.1 Identify Reusable Sections

For example, a simple HTML structure:

<header>
  <h1>Welcome to My Website</h1>
</header>
<nav>
  <ul>
    <li><a href="index.html">Home</a></li>
    <li><a href="about.html">About</a></li>
  </ul>
</nav>
<main>
  <h2>About Us</h2>
  <p>This is an about page.</p>
</main>
<footer>
  <p>© 2024 My Website</p>
</footer>

Can be divided into:

  • Header.js
  • Nav.js
  • Footer.js
  • Home.js
  • About.js

3.2 Create Components

Create a components folder inside src/ and add files like Header.js, Nav.js, and Footer.js.

Header Component (Header.js)

import React from 'react';

const Header = () => {
  return (
    <header>
      <h1>Welcome to My Website</h1>
    </header>
  );
};

export default Header;

Navigation Component (Nav.js)

import React from 'react';

const Nav = () => {
  return (
    <nav>
      <ul>
        <li><a href="/">Home</a></li>
        <li><a href="/about">About</a></li>
      </ul>
    </nav>
  );
};

export default Nav;

Footer Component (Footer.js)

import React from 'react';

const Footer = () => {
  return (
    <footer>
      <p>© 2024 My Website</p>
    </footer>
  );
};

export default Footer;

Main Content Components (Home.js & About.js)

import React from 'react';

const Home = () => {
  return (
    <main>
      <h2>Home Page</h2>
      <p>Welcome to the home page!</p>
    </main>
  );
};

export default Home;
import React from 'react';

const About = () => {
  return (
    <main>
      <h2>About Us</h2>
      <p>This is an about page.</p>
    </main>
  );
};

export default About;

Step 4: Implement React Router

To navigate between pages, install React Router:

npm install react-router-dom

Modify App.js to use routing:

import React from 'react';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import Header from './components/Header';
import Nav from './components/Nav';
import Footer from './components/Footer';
import Home from './pages/Home';
import About from './pages/About';

function App() {
  return (
    <Router>
      <Header />
      <Nav />
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="/about" element={<About />} />
      </Routes>
      <Footer />
    </Router>
  );
}

export default App;

Step 5: Convert CSS to React-Friendly Format

If your CSS is global, you can import it inside index.css or App.css:

import './assets/css/style.css';

For module-based styling, rename CSS files to .module.css and use them like this:

import styles from './Header.module.css';

const Header = () => {
  return (
    <header className={styles.header}>
      <h1>Welcome</h1>
    </header>
  );
};

Step 6: Convert JavaScript to React State & Hooks

If your HTML site has a JavaScript file (script.js) that manages interactivity, convert it into React state and hooks.

Example: Handling a Button Click

Before (HTML + JS):

<button id="clickMe">Click Me</button>
<script>
  document.getElementById("clickMe").addEventListener("click", function () {
    alert("Button clicked!");
  });
</script>

After (React + Hooks):

import React, { useState } from 'react';

const ClickButton = () => {
  const [message, setMessage] = useState('');

  const handleClick = () => {
    setMessage('Button clicked!');
  };

  return (
    <div>
      <button onClick={handleClick}>Click Me</button>
      {message && <p>{message}</p>}
    </div>
  );
};

export default ClickButton;

Step 7: Test Your React App

To run your new React website:

npm start

Your site should now be running at http://localhost:3000/.

Step 8: Deploy the React App

Once everything is working fine, deploy your React app.

8.1 Build the Production Version

npm run build

8.2 Deploy to GitHub Pages

  1. Install gh-pages
npm install gh-pages --save-dev
  1. Update package.json
"homepage": "https://yourusername.github.io/your-repo-name",
"scripts": {
  "predeploy": "npm run build",
  "deploy": "gh-pages -d build"
}
  1. Deploy:
npm run deploy

Alternatively, you can deploy via Vercel, Netlify, or Firebase.
