npm and TypeScript Setup Guide for Linux

Follow these steps to install Node.js (which includes npm) and the TypeScript compiler on Linux. The specific commands might vary slightly depending on your distribution.

General Steps (using package managers):

1. Update Package Lists:

   • Debian/Ubuntu:

     sudo apt update

   • Fedora/CentOS/RHEL:

     sudo dnf update
     # or
     sudo yum update

   • Arch Linux:

     sudo pacman -Syu

2. Install Node.js and npm:

   • Debian/Ubuntu (Recommended - using NodeSource):

     curl -sL [https://deb.nodesource.com/setup_lts.x](https://deb.nodesource.com/setup_lts.x) | sudo -E bash -
     sudo apt-get install -y nodejs

     (Replace lts.x with the desired LTS version, e.g., setup_20.x)
   • Debian/Ubuntu (Alternative):

     sudo apt install nodejs npm

     (You might need sudo apt install nodejs-legacy as well)
   • Fedora/CentOS/RHEL:

     sudo dnf install nodejs npm
     # or
     sudo yum install nodejs npm

   • Arch Linux:

     sudo pacman -S node npm

3. Verify Node.js and npm Installation:

   • Open your Terminal.

   • Run the following commands to check the installed versions:

     node -v

     Expected Output: A version number (e.g., v18.16.0)

     npm -v

     Expected Output: A version number (e.g., 9.5.1)

4. Install TypeScript Compiler:

   • In the same Terminal window, run the following command to install TypeScript globally:

     npm install -g typescript

5. Verify TypeScript Installation:

   • Run the following command to check the installed version of the TypeScript compiler:

     tsc -v

     Expected Output: A version number (e.g., Version 5.0.4)

Now you have npm and the TypeScript compiler installed on your Linux system. Remember to adjust the installation commands based on your specific Linux distribution.
