For Windows

Method 1: Using the Official Installer

1. Download the installer:

• Go to Node.js official website

• Download the LTS (Long Term Support) version (recommended for most users)

2. Run the installer:

• Double-click the downloaded .msi file
• Follow the installation wizard (you can accept all defaults)

3. Verify installation:

• Open Command Prompt (cmd)
• Type

node -v
npm -v

• This should display the installed versions

Method 2: Using Chocolatey (Package Manager)

1. Install Chocolatey (if you don’t have it):

   @"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

2. Install Node.js:

   choco install nodejs

For macOS

Method 1: Using Official Installer

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install Node.js:

   brew install node

For Linux (Ubuntu/Debian)

Method 1: Using NodeSource PPA (Recommended)

1. Install curl (if not already installed):

   sudo apt-get install curl

sudo apt update
sudo apt install nodejs npm

Post-Installation Steps (All OS)

1. Update npm (optional but recommended):

   npm install -g npm@latest

2. Check for global npm permissions:

• If you get permission errors, you might need to:
  • Reinstall with a version manager (like nvm)
  • Change npm’s default directory
  • Use sudo (not recommended for security reasons)

Optional: Install Using Node Version Manager (nvm)

nvm allows you to install and switch between multiple Node.js versions:

1. Install nvm:

• Linux/macOS:
  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
• Windows: Use nvm-windows

   nvm install --lts

3. Use a specific version:

   nvm use 14.17.0

2. Download the Composer-Setup.exe file by clicking on the “Windows Installer” option.

3. Once the file is downloaded, double-click on it to run the installer.

4. The installer will guide you through the setup process. You can leave the default settings as they are or customize them as per your preference.

5. When you reach the “Installation Options” screen, make sure the “Add Composer to PATH” option is checked. This will allow you to use Composer from any directory in the Command Prompt.

6. Continue with the installation by following the remaining on-screen instructions.

7. After the installation finishes, open a new Command Prompt window (or restart it if it was already open).

8. To verify if Composer is installed properly, type “composer” in the Command Prompt and press Enter. It should display the Composer version and a list of available commands.

That’s it! Composer is now installed on your Windows system, and you can start using it for managing your PHP dependencies.
