Introduction
React is a popular JavaScript library for building user interfaces. If you are using a Mac and want to set up your local development environment to run React applications, this guide will walk you through the necessary steps.
Step 1: Install Homebrew
Homebrew is a package manager for macOS that helps install various development tools easily.
Once installed, verify it with:
Step 2: Install Node.js and npm
Node.js is required to run React applications, and npm (Node Package Manager) comes bundled with it.
Install Node.js using Homebrew:
Check if Node.js and npm are installed correctly:
Step 3: Install a Code Editor (Optional)

Navigate into your project directory:
Step 5: Start the Development Server
To see your React app in action, start the development server:
This will open a new browser window at `http://localhost:3000/` with your running React application.
Step 6: Understanding React Project Structure
When you create a new React app, it includes the following structure:
Step 7: Install Additional Dependencies
You may want to install additional libraries such as React Router:
