**Title: How to Install and Run React JS in Visual Studio Code | Complete Guide** **Description:** In this tutorial, learn how to **install and run a React JS application in Visual Studio Code (VS Code)** from scratch. React JS is a powerful JavaScript library for building user interfaces, and VS Code is a versatile, developer-friendly IDE that makes working with React projects a breeze. Whether you’re new to React or looking to optimize your setup, this guide will walk you through creating, setting up, and running your first React app in VS Code. ### What You’ll Learn:
1. Installing Node.js and npm
2. Creating a New React App with Create React App
3. Opening and Running the React App in VS Code
4. Basic VS Code Extensions for React Development ### Step 1: Install Node.js and npm
To start, you’ll need to have **Node.js** and **npm** installed, as React relies on Node for development. – Download the latest version of Node.js from the [Node.js official website](https://nodejs.org/).
– Install it, which includes npm, a package manager required for React. Confirm the installation by opening a terminal and running:
“`bash
node -v
npm -v
“` ### Step 2: Create a New React App
Now, create a new React project using **Create React App**, a tool for setting up a new React project quickly. 1. Open your terminal.
2. Run the following command to create a React project named “my-app”: “`bash npx create-react-app my-app “`
3. This will set up a basic React app with all necessary dependencies. After installation, navigate into the project folder: “`bash cd my-app “` ### Step 3: Open the Project in Visual Studio Code
1. Open **Visual Studio Code**.
2. Click on **File – Open Folder…** and navigate to the “my-app” folder.
3. Once opened, you’ll see the full file structure, including files like `App.js` and `index.js`, which are central to your React application. ### Step 4: Run Your React Application
1. In VS Code’s integrated terminal, ensure you are in the project directory (`my-app`) and run: “`bash npm start “`
2. This will start the development server, and your React app will open automatically in the default web browser at `http://localhost:3000`. You should see the default “Welcome to React” page if everything is set up correctly! ### Step 5: Customize VS Code for React Development (Optional)
For an enhanced development experience, consider adding these VS Code extensions:
– **ES7+ React/Redux/React-Native snippets**: For quickly adding React snippets.
– **Prettier – Code Formatter**: Helps keep your code clean and consistent.
– **JavaScript (ES6) code snippets**: Adds additional useful snippets. ### Summary and Troubleshooting
– **Installation Issues**: Ensure Node and npm are correctly installed.
– **Error Messages**: If `npm start` throws errors, try deleting the `node_modules` folder and running `npm install` again. By the end of this tutorial, you’ll have a React app running in Visual Studio Code, ready to customize and build upon.
