In the ever-evolving world of web development, ReactJS stands out as a powerful JavaScript library for building user interfaces, especially single-page applications. Whether you’re a seasoned developer or just starting, installing ReactJS on AlmaLinux 9 can be a straightforward process with the right guidance. This article aims to demystify the installation process, providing a clear, step-by-step guide that newcomers can easily follow while offering depth and technical insight for more experienced users.

Step 1: Installing Node.js and npm

Node.js is a runtime environment for executing JavaScript code server-side, and npm is its package manager, which you’ll need to manage your ReactJS project’s dependencies. To install both Node.js and npm on AlmaLinux 9, follow these commands:

1. Update Your System First, ensure your system’s package index is up-to-date:

   sudo dnf update -y

2. Install Node.js and npm AlmaLinux’s default repositories contain Node.js and npm. Install them using the dnf package manager:

   sudo dnf install nodejs -y

This command installs both Node.js and npm since npm is bundled with Node.js.

3. Verify Installation Check the installed versions to ensure Node.js and npm are correctly installed:

   node -v
   npm -v

The output should display the installed versions of Node.js and npm, respectively.

Step 2: Installing ReactJS

With Node.js and npm installed, you’re now ready to set up a ReactJS project. ReactJS projects are initiated using the Create React App command-line utility, which scaffolds a new React project with a good default configuration.

1. Create a New ReactJS Project Choose a directory where you want your project to reside and run the following command to create a new ReactJS project:

   npx create-react-app my-react-app

Replace my-react-app with your desired project name. This command creates a new directory with the project name and sets up the React project structure within.

2. Navigate to Your Project Directory Change to your project directory:

   cd my-react-app

3. Start the React Development Server Initiate the development server to start working on your project:

   npm start

This command runs the app in development mode, opening up a tab in your default web browser to display the React app. The page will automatically reload if you make edits.

Step 3: Developing Your ReactJS Application

With ReactJS installed, you can begin developing your application. The src directory will contain your app’s source code, where you can modify App.js to start building your React components.
