Step-by-Step Guide
1. Prerequisites
Before starting with React development, you need a couple of tools:
React relies on Node.js, and you’ll use npm (Node Package Manager) or Yarn to manage packages.

Download Node.js and install it.
npm is included, but you can install Yarn separately if you like. After installation,
check your versions by running:
node -v
npm -v
2. Create a New React App
Creating a new React app is straightforward with Create React App (CRA). You can do this in two main ways: by using npx or by installing Create React App globally. Each method comes with its advantages and disadvantages, allowing you to choose the one that best fits your workflow.

i. Using npx
To create a new React app with npx, run the following commands
npx create-react-app my-app
cd my-app
npm start
Advantages of Using npx:
- Latest Version: Always use the most recent version of Create React App.
- No Clutter: No need for global installation, keeping your system clean.
Disadvantages of Using npx:
- Slower Initial Run: The first run may be slower as it downloads the package.
- Internet Required: An internet connection is needed each time you create a new app.
ii. Global Installation
Alternatively, you can install Create React App globally:
npm install -g create-react-app
create-react-app my-app
cd my-app
npm start
Advantages of Global Installation:
Faster app creation since it’s already on your system.
Disadvantages of Global Installation:
- You might forget to update it, leading to inconsistencies.
- Your system can get cluttered with too many global packages.
Both methods will create a new React project with a fully configured development environment, including Webpack, Babel, and a development server with hot-reloading.
3. React Developer Tools
To debug effectively in the browser, install the React Developer Tools extension for Chrome or Firefox. This tool allows you to:
Inspect Component Trees: View and debug your React components.
See Current State and Props: Easily check the state and props of your components.
Visualize Re-renders: Analyze how your components update.
Check Performance: Use Lighthouse to evaluate your web app’s performance score, which shows how fast your site loads and how well it performs in areas like accessibility and SEO.
Manage Redux Store: If you’re using Redux, this tool helps you inspect and manage your Redux store.
4. Linting and Formatting
Setting up code linting and formatting ensures your code is consistent:
ESLint: Helps catch common mistakes early. Add it with: npm install eslint eslint-plugin-react --save-dev
Prettier: Automatically formats your code. Install it with: bash npm install --save-dev prettier eslint-config-prettier eslint-plugin-prettier
You can also find Prettier extensions for your code editor to streamline your workflow.
5. Version Control with Git
Using Git is essential for managing your code and collaborating with others.
To set up a Git repository, run:
git init
You can use platforms like GitHub or GitLab to host your code and work with your team.
6. Hot Module Replacement (HMR)
React’s hot module replacement allows you to see changes in the browser instantly without a full page refresh.
This feature is built into Create React App, but you can also use tools like Vite for even faster updates.

FAQ's
To set up ReactJS, you’ll need:
1. Node.js (LTS version recommended) for running the development server and managing dependencies.
2. A code editor such as VS Code, WebStorm, or Atom to write and edit your code.
3. A package manager like npm or Yarn to handle packages.
4. A modern browser like Chrome or Firefox for testing.
You'll have an easy time learning React if you're already well-versed in JavaScript, but it can be challenging if you don't have little or no experience in JavaScript beforehand. That's why it's recommended to learn JavaScript first.
Babel is a JavaScript compiler that converts modern JavaScript (ES6 and later) and JSX into code that can run in older browsers. It allows developers to use the latest features of JavaScript without worrying about browser compatibility.
In React, Babel is essential for converting JSX syntax (which is not natively supported by browsers) into regular JavaScript, making it possible to render React components correctly.
To set up the environment for ReactJS, you must have Node.js installed on your machine. Node.js is required for running the development server and managing dependencies through npm or yarn. This setup is consistent across Windows, macOS, and Linux.You can download Node.js from the official website here.
