Why Choose React for Web Development?
Before diving into the process, it’s important to understand why React web development is the go-to choice for developers and businesses:
- Component-Based Architecture: Reusable components make development faster and more organized.
- Virtual DOM: React ensures high performance by updating only the parts of the page that change.
- SEO-Friendly: When paired with server-side rendering, React can improve SEO.
- Large Community Support: React is backed by Facebook and a vast community of developers.
- Cross-Platform Capabilities: React Native extends React to mobile app development.
Businesses can create user-friendly, scalable web applications tailored to their needs by leveraging these benefits.

Step-by-Step Guide to Build a React App Using Create-React-App
1. Prerequisites
Before starting, ensure you have the following tools installed on your system:
- Node.js: React requires Node.js to run the development server. Download it from nodejs.org.
- npm or Yarn: Package managers to install React dependencies.
- Code Editor: VS Code is highly recommended for React development.
Verify Node.js and npm installations by running these commands in your terminal:
node -v
npm -v
2. Install Create-React-App
To create your React project, run the following command in your terminal:
npx create-react-app my-first-react-app
Here:
- npx is a package runner that comes with npm.
- create-react-app is the official React scaffolding tool.
- Replace my-first-react-app with your project name.
This command will create a directory with all the required dependencies, scripts, and folders for a React app.
3. Navigate to Your Project Folder
Once the installation is complete, move into the project directory:
cd my-first-react-app
4. Start the Development Server
Launch the React app using the following command:
npm start
This will:
- Start a local development server.
- Open the React app in your default browser at http://localhost:3000.
You will see the default React welcome page with a spinning React logo if everything is successful.
5. Explore the Project Structure
The Create-React-App tool generates a standard folder structure:
- public/: Contains the HTML file where your React app is rendered.
- src/: Contains the React components, CSS, and other logic files.
- node_modules/: Includes all the project dependencies.
- package.json: Lists project metadata, dependencies, and scripts.
You can now start editing the files inside the src/ directory to customize your React app.
Create Your First Component:
a. Inside the src/ folder, create a file named Welcome.js.
b. Add the following code:
import React from ‘react’;
function Welcome() {
return (
<h1>Welcome to My First React App!</h1>
);
}
export default Welcome;
c. Open App.js and replace the contents with:
import React from ‘react’;
import Welcome from ‘./Welcome’;
function App() {
return (
<div>
<Welcome />
</div>
);
}
export default App;
d. Save the files and refresh the browser. Your React app will display the welcome message.
