Install Node.js for Windows

Written on September 23, 2013

Node.js is a platform built on Chrome’s V8 JavaScript engine for easily building fast and scalable network (especially server-side) applications.

Installing Node.js for Windows these days is super simple. Just download the Windows Installer and install it with the default features to a directory of your choice. That’s it.

Note that in most cases it shouldn’t make a difference if you pick the 32 or 64-bit version.

To check if Node.js installed correctly, open a PowerShell window or - if you’re feeling nostalgic - a Command Prompt window and simply type node.

PS > node
>

You are now in an interactive Node.js shell and can start typing JavaScript commands. For instance try typing 3+2. That’s right, you could use Node.js as a fancy calculator. Sweet.

PS > node
> 3+2
5

To exit the shell at any time press Ctrl + C.

Of course usually you want to put your JavaScript code into a file and execute it with Node.js. So let’s just jump in the water and write a simple “Hello World” program.

Open your favorite text editor, create a file helloworld.js and add the following line of code:

console.log("Hello World");

Save the file in the same directory where you installed Node.js and execute it with the node program through node helloworld.js.

PS > node helloworld.js
Hello World
