Learning with Treehouse starts at only $25 per month. The NPM site lists all of the official Node packages making it easy to make the choice. With Node.js and NPM installed you’ll soon be able to take advantage of the huge world of NPM modules that can help with a wide variety of tasks both on the web server and on your desktop (or laptop) machine.

Select Node.js, and click the Uninstall link.

Choose the “Programs and Features” option.

You uninstall Node.js and NPM the same as you would most Windows software: The new version of Node and NPM will replace the older versions.

Nodejs windows install#

To install the updates, just download the installer from the site and run it again. New versions of Node and NPM come out frequently.

Nodejs windows update#

You should see the output Node is installed!.Ĭheck and Update Your Node and NPM Versions

This will start Node and run the code in the hello.js file.

To run the code simply open your command line program, navigate to the folder where you save the file and type node hello.js. A simple way to test that node.js works is to create a JavaScript file: name it hello.js, and just add the code console.log('Node is installed!'). This should print NPM’s version number so you’ll see something like this 1.4.28 To see if NPM is installed, type npm -v in Terminal. This should print a version number, so you’ll see something like this v0.10.35. To see if Node is installed, open the Windows Command Prompt, Powershell or a similar command line tool, and type node -v. Make sure you have Node and NPM installed by running simple commands to see what version of each is installed and to run a simple test program: You won’t be able to run Node.js® until you restart your computer.

Follow the prompts in the installer (Accept the license agreement, click the NEXT button a bunch of times and accept the default installation settings).

msi file you downloaded in the previous step.)

Download the Windows installer from the Nodes.js® web site.

Installing Node and NPM is pretty straightforward using the installer package available from the Node.js® web site.

Nodejs windows how to#

To use Node you must type command-line instructions, so you need to be comfortable with (or at least know how to start) a command-line tool like the Windows Command Prompt, PowerShell, Cygwin, or the Git shell (which is installed along with Github for Windows). Node isn’t a program that you simply launch like Word or Photoshop: you won’t find it pinned to the taskbar or in your list of Apps. Using NPM - a tool that makes installing and managing Node modules - it’s quite easy to add many useful tools to your web development toolkit. For example, by installing Node.js® on your desktop machine, you can quickly convert CoffeeScript to JavaScript, SASS to CSS, and shrink the size of your HTML, JavaScript and graphic files. Node.js is also used for developing desktop applications and for deploying tools that make developing web sites simpler. The key to this server-side JavaScript revolution is Node.js® - a version of Chrome’s V8 JavaScript runtime engine - which makes it possible to run JavaScript on the server-side. What is the Difference Between Node & NMP? Fortunately, for Windows users, the Node.js® installation process is a lot easier than how I recommend installing Node.js® on a Mac. In a previous article, I wrote about how to install Node.js® and, it’s companion, NPM on a Mac. In fact, concentrating on JavaScript as your language of choice offers the opportunity to master a single language while still being able to develop “full-stack” web applications. Web developers who work on the server-side are also flocking to JavaScript because of the efficiencies and speed offered by JavaScript’s event-driven, non-blocking nature. Front-end web developers use JavaScript to add user interface enhancements, add interactivity, and talk to back-end web services using AJAX. JavaScript is quickly becoming the go-to language for web developers. Try our program out with a free seven-day trial today. If you’re looking to take your JavaScript coding to another level, Treehouse offers unlimited courses in JavaScript (and many other subjects) starting at $25/month.
