Node.js and npm Overview

What is npm?

npm (node.js package manager) is the package manager for JavaScript and the world’s largest software registry, allowing developers to discover and assemble reusable code packages.

What is Node.js?

Definition: Node.js executes JavaScript code outside of a browser.

Traditional JavaScript

  • JavaScript is primarily used for client-side scripting
  • Scripts are embedded in HTML and executed by the browser’s JavaScript engine
  • Complex computations can slow down client devices (computers, smartphones, etc.)

Node.js Advantage

Node.js enables developers to:

  • Execute JavaScript on a server instead of the client
  • Run scripts server-side to generate dynamic web content
  • Create command-line tools and server-side applications
  • Offload computational load from client devices to servers

npm as a Package Manager

npm solves a key problem: code reuse. Instead of rewriting code, developers can download and use packages written by others.

Example: Express Framework

A popular npm package, express is a lightweight web framework that enables:

  • Simple web routing
  • Handling different URLs to serve different webpages
  • Managing multiple routes from a single server This approach makes development faster and more efficient. —

    Node.js Installation

    To install Node.js on WSL (Ubuntu), the most flexible and recommended method is

using Node Version Manager (NVM). This allows you to manage multiple versions of Node.js and avoids common permission issues with global packages.

Method 1: Using NVM (Recommended)

This is the standard approach for developers because it makes updating and switching versions easy.

  1. Install cURL: Ensure you have the tool needed to download the installer.

    bash

    1

    sudo apt update && sudo apt install curl -y

    Use code with caution.

  2. Download and Run NVM Installer: Get the script from the official nvm-sh GitHub repository.

    bash

    1

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash

    Use code with caution.

  3. Reload Your Shell: Close and reopen your WSL terminal, or run the following to apply the changes immediately:

    bash

    1

    source ~/.bashrc

    Use code with caution.

  4. Install Node.js:

    • To install the latest LTS (Long-Term Support) version (recommended for most users):

      bash

      1

      nvm install --lts

      Use code with caution.

    • To install the absolute latest release:

      bash

      1

      nvm install node

      Use code with caution.

  5. Verify Installation: Check that both Node and npm (Node Package Manager) are active.

    bash

    1
2

    node -v
npm -v

    1

        * * *

Method 2: Using Ubuntu Repositories (Quickest)

If you only need a basic installation and don’t care about having the latest version, use the built-in package manager.

  1. Install Node.js:

    bash

    1
2

    sudo apt update
sudo apt install nodejs npm -y

    Use code with caution.

  2. Verify:

    bash

    1

    node -v

    Use code with caution.

Important Tips for WSL Users

  • Avoid Windows-side Node.js: Do not try to call the Windows version of Node.js from your WSL terminal. It can cause pathing issues and performance slowdowns.
  • File Performance: Keep your project files in the Linux file system (e.g., ~/projects/) rather than on the Windows side (/mnt/c/) for much faster performance.

  • VS Code Integration: If using VS Code, install the WSL extension to run your code directly in the Ubuntu environment.
