1. Installing Node.js and npm

Node.js and npm (Node Package Manager) are prerequisites for creating and running React applications.

1. Download and Install Node.js:
   • Visit the Node.js official website.
   • Download the LTS version for stability.
   • Follow the installation instructions for your operating system.
2. Verify Installation:
   • Open a terminal and run the following commands:

node -v
npm -v

• These commands will display the installed versions of Node.js and npm.

2. Setting up a React Project

1. Install Vite Vite is a fast frontend build tool.
   • Open a terminal and run

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

- Replace `my-react-app` with your desired project name.

2. Navigate to the Project Directory:

cd my-react-app

3. Install Dependencies Run the following command to install all the dependencies

   npm install
   

4. Run the Development Server Start the Vite development server to preview your app

   npm run dev
   

   • The terminal will display a URL (e.g., http://localhost:5173) where you can view your app in the browser.

3. Overview of the Project Folder Structure

Once the setup is complete, your project folder will look like this:

my-react-app/
├── node_modules/           # Installed npm packages
├── public/                 # Static assets (e.g., images, icons)
│   └── vite.svg            # Default Vite logo
├── src/                    # Source code of your application
│   ├── App.css             # Styles for the App component
│   ├── App.jsx             # Main React component
│   ├── main.jsx            # Entry point for the application
│   └── index.css           # Global styles
├── .gitignore              # Files and folders to ignore in Git
├── package.json            # Project metadata and dependencies
├── vite.config.js          # Configuration file for Vite
└── README.md               # Project documentation

Key Files and Folders:

• src/main.jsx: Entry point for your React app. It renders the root component (App.jsx).
• src/App.jsx: Default React component created by Vite. Customize this file to start building your app.
• public/: Store static assets like images or fonts.
• package.json: Manages dependencies, scripts, and project metadata.
• vite.config.js: Customize the build tool’s behavior (e.g., plugins, server options).
