node js

JavaScript is rapidly becoming the preferred language for web developers, serving both front-end and server-side needs. Front-end developers harness JavaScript to enrich user interfaces, introduce interactivity, and communicate with back-end services via AJAX. On the server side, JavaScript’s event-driven, non-blocking nature is attracting developers for its efficiency and speed, making it the go-to choice for building “full-stack” web applications. In a previous article, we discussed installing Node.js® and NPM on Mac; however, Windows users have a simpler installation process.

Understanding Node.js and NPM

Node.js: A Game-Changer Node.js® is at the forefront of the server-side JavaScript revolution. It’s essentially a version of Chrome’s V8 JavaScript runtime engine, enabling JavaScript execution on servers. Beyond this, Node.js finds application in desktop application development and simplifying web development by facilitating tasks like CoffeeScript to JavaScript conversion, SASS to CSS transformation, and file size reduction for HTML, JavaScript, and graphics. With NPM (Node Package Manager), which simplifies module installation and management, you can expand your web development toolkit effortlessly.

Determining When to Use Node.js

Command-Line Proficiency Required Node isn’t a conventional program like Word or Photoshop; it doesn’t appear on the taskbar or in your list of Apps. To utilize Node, you must be comfortable with, or at least know how to start, a command-line tool such as the Windows Command Prompt, PowerShell, Cygwin, or the Git shell (bundled with Github for Windows).

Installation Steps

Streamlined Installation Process Installing Node.js and NPM is a straightforward process, thanks to the installer package available on the Node.js® website.

  1. Download the Installer: Begin by downloading the Windows installer from the Node.js® website.
  2. Run the Installer: Execute the installer (the .msi file you downloaded) and proceed by following the prompts. This involves accepting the license agreement, clicking the NEXT button multiple times, and accepting the default installation settings.

Verifying Node and NPM Installation

Ensuring Successful Installation To confirm that Node and NPM have been successfully installed, execute simple commands to check their versions and run a basic test program.

  1. Testing Node: Open the Windows Command Prompt, PowerShell, or a similar command-line tool and enter the command node -v. This command should display the Node version, e.g., v0.10.35.
  2. Testing NPM: To check if NPM is installed, use the command npm -v in your terminal. This will display the NPM version, e.g., 1.4.28.
  3. Running a Test File: Create a test JavaScript file named hello.js and include the code console.log('Node is installed!');. To execute the code, open your command-line program, navigate to the file’s folder, and type node hello.js. You should see the output: “Node is installed!”.
Managing Node and NPM Versions

Staying Up-to-Date New versions of Node and NPM are regularly released. To update your installations, download the latest installer from Nodejs.org and run it. The new versions will replace the older ones seamlessly.

Uninstalling Node and NPM

Simple Removal Process Uninstalling Node.js and NPM is as straightforward as removing any Windows software:

  1. Open Control Panel: Access the Windows Control Panel.
  2. Select “Programs and Features”: Choose the “Programs and Features” option.
  3. Uninstall Node.js: Locate Node.js in the list of installed programs and click the “Uninstall” link.

Embrace the World of NPM Modules

Unlocking the Potential With Node.js and NPM in place, you’ll gain access to a vast array of NPM modules that can streamline various tasks on both web servers and desktop machines. The NPM website provides a comprehensive list of official Node packages, making it simple to choose the right tools for your needs.
