To run a React program in VS Code, first install Node.js from nodejs.org. Open VS Code, create a new React app using npx create-react-app my-app in the terminal, then navigate to the app folder with cd my-app. Install dependencies with npm install and start the app using npm start in the terminal.

To run a React program in Visual Studio Code (VS Code), follow these steps:

1. Set Up Your React Project

If you haven't already created a React project, you can use create-react-app to set it up:

npx create-react-app my-react-app

This will create a new React project in a directory called my-react-app.

2. Open the Project in VS Code

3. Open VS Code.

4. Click on File > Open Folder... and navigate to your React project directory (e.g., my-react-app).

5. Select the folder to open it in VS Code.

6. Install Dependencies

If you cloned an existing React project or downloaded one, you need to install the necessary dependencies:

1. Open a terminal in VS Code by going to View > Terminal.

2. Make sure you're in the root directory of your React project.

3. Run the following command to install dependencies:

   npm install
   

4. Run the React Application

To start the React development server:

1. In the terminal, make sure you're in the root directory of your React project.

2. Run the following command:

   npm start
   

This command will start the development server, and you should see output in the terminal showing that the server is running.

1. Install Node.js and npm

• Download and install Node.js (which includes npm).
• To check if they're installed correctly, run the following commands in your terminal: node -v npm -v

2. Set Up a React Project

• Open a terminal in VS Code (Ctrl + ~) and navigate to the folder where you want to create your React project.
• Run the following command to create a new React app using create-react-app (a simple way to set up a React environment): npx create-react-app my-app
• Replace my-app with the desired name of your project.

3. Open the Project in VS Code

• Once the project is created, navigate into the project folder: cd my-app
• Then open the folder in VS Code: code .

4. Start the Development Server

• In the terminal, run: npm start
• This will start the development server, and your React app will be accessible at http://localhost:3000 in your browser.

5. Make Changes and See Live Updates

• As you modify the code in VS Code, the browser will automatically reload and reflect the changes. This setup lets you develop and run React applications directly in VS Code!

⚙️ 1️⃣ Install Node.js

React requires Node.js and npm (Node Package Manager).

👉 Check if it’s already installed:

Open your VS Code terminal and run:

node -v npm -v

If both show version numbers — perfect. If not, install Node.js:

🧩 Install (on Kali/Ubuntu/Linux) sudo apt update sudo apt install nodejs npm -y

Optionally, install the latest version from Node’s website: 👉 https://nodejs.org

⚙️ 2️⃣ Create a New React App

You can use either Create React App or Vite (modern and faster). I’ll show both ways 👇

✅ Option 1 — Using Create React App (Simple) npx create-react-app my-react-app cd my-react-app npm start

That’s it 🎉 — it will open automatically in your browser at 👉 http://localhost:3000

✅ Option 2 — Using Vite (Recommended for speed) npm create vite@latest my-react-app

Then select:

React JavaScript

Now run:

cd my-react-app npm install npm run dev

This will start your React app at 👉 http://localhost:5173

⚙️ 3️⃣ Open in VS Code

You can open the project folder directly from terminal:

code my-react-app

(or open VS Code manually → File → Open Folder → choose your project).

🧠 4️⃣ Folder Structure (for reference) my-react-app/ ├── node_modules/ ├── public/ ├── src/ │ ├── App.js │ ├── index.js │ ├── components/ │ └── ... ├── package.json └── vite.config.js (if using Vite)

🧰 5️⃣ Run the Project Anytime

To start the React app again after closing VS Code:

cd my-react-app npm start

(for Create React App)

or

npm run dev

(for Vite)

💡 Optional (Useful VS Code Extensions)

ES7+ React/Redux/React-Native snippets → for fast React boilerplates.

Prettier → for auto code formatting.

React Developer Tools (browser extension) → for debugging components.
