Get Started with ReactJS

ReactJS is a powerful JavaScript library for building user interfaces, primarily for single-page applications (SPAs). It allows developers to create reusable UI components for efficient and scalable applications.


📌 Step 1: Prerequisites

Make sure you have the following installed:

  • Node.js (Download from Node.js website)

  • npm or yarn (Package managers installed with Node.js)

Check versions:

bash

node -vnpm -v


📌 Step 2: Install React Using Vite (Faster Alternative to CRA)

Vite is a modern build tool optimized for speed and performance.

Create a New React Project Using Vite

bash

npm create vite@latest my-react-app -- --template react<div> <React.StrictMode> <div> <h1>Count: {count}</h1> <button onClick={() => setCount(count + 1)}>Increment</button> </div> );};export default Counter;

  • useState() → Hook for managing state.

  • onClick → Event handler.


📌 Step 9: Build for Production

When you're ready to deploy:

bash

npm run build

  • Output files will be in the /dist folder.

  • Optimized for production.


Next Steps
