Getting Started with Create React App

1. Introduction

Create React App is a comfortable environment for learning React, and it helps in creating single-page applications with no configuration. It provides a modern build setup with no configuration.

2. Installation

Follow these steps to install Create React App:

1. Ensure you have Node.js installed on your machine. You can download it from nodejs.org.
2. Open your terminal/command prompt.
3. Run the following command to create a new React app:

npx create-react-app my-app

Replace my-app with your desired project name.

3. Project Structure

Once your project is created, the directory structure will look like this:

my-app/
├── node_modules/
├── public/
│   ├── favicon.ico
│   ├── index.html
│   └── manifest.json
└── src/
    ├── App.css
    ├── App.js
    ├── App.test.js
    ├── index.css
    ├── index.js
    └── logo.svg
            

Key folders:

• public/: Contains static files that will be served directly.
• src/: Contains React components and application logic.

4. Running the App

To start the development server, navigate to your project directory and run:

cd my-app
npm start

This will open your application in the default web browser at http://localhost:3000.

5. Best Practices
