- Using a Node version manager to install Node.js and npm
- Using a Node installer to install Node.js and npm
To publish and install packages to and from the public npm registry or a private npm registry, you must install Node.js and the npm command line interface using either a Node version manager or a Node installer. We strongly recommend using a Node version manager like nvm to install Node.js and npm. We do not recommend using a Node installer, since the Node installation process installs npm in a directory with local permissions and can cause permissions errors when you run npm packages globally.
Note: to download the latest version of npm, on the command line, run the following command:
Checking your version of npm and Node.js
To see if you already have Node.js and npm installed and check the installed version, run the following commands:
Using a Node version manager to install Node.js and npm
Node version managers allow you to install and switch between multiple versions of Node.js and npm on your system so you can test your applications on multiple versions of npm to ensure they work for users on different versions.
OSX or Linux Node version managers
Windows Node version managers
Using a Node installer to install Node.js and npm
If you are unable to use a Node version manager, you can use a Node installer to install both Node.js and npm on your system.
If you use Linux, we recommend that you use a NodeSource installer.
OS X or Windows Node installers
If you're using OS X or Windows, use one of the installers from the Node.js download page. Be sure to install the version labeled LTS. Other versions have not yet been tested with npm.
Linux or other operating systems Node installers
If you're using Linux or another operating system, use one of the following installers:
- NodeSource installer (recommended)
- One of the installers on the Node.js download page
Or see this page to install npm for Linux in the way many Linux developers prefer.
Less-common operating systems

I find myself writing about this over and over again in the prerequisites of an article I've begun to write. I'd prefer to write one definitive guide to refer to in the future, so here it is.

What is Node.js?
What is npm?
npm doesn't stand for Node Package Manager*, which means it’s the tool to connect to the repository containing all the Node.js programs, plugins, modules and so on.
*npm actually does not stand for 'Node Package Manager' but essentially that's what it is and does, so most people refer to it that way.
Local vs. Global
This is the most confusing concept to understand at first, so it's important to let this settle in. Traditionally, you're used to globally installing any sort of program or software on your computer. If you want Spotify, you'll download Spotify, and then it will be available to you.
With npm, you will have some global installs, but mostly everything will be done on a local project basis, meaning you'll have to install everything you need for each project in its own directory. If you want to have a project running Gulp and Sass, you'll create a directory, with a new npm install.
For future reference, any global installations will have the
Installation on Windows
Installing everything on Windows is a breeze.
Install Node.js and npm
Node.js and npm can be installed from a download link. Go to the Node installation page, and download the Node installer. I have a 64-bit Windows 10 OS, so I chose that one.
Once it's done, you can test to see both node and npm functioning by opening PowerShell (or any shell) and typing
node -v and
npm -v, which will check the version number.
Installation on a Mac or Linux
In order to install everything on a Mac, we'll be running commands in Terminal.app, and Linux distributions vary.
Install Node.js and npm
We’re going to use Node Version Manager (nvm) to install Node.js and npm.
~/.bash_profile file, and make sure
source ~/.bashrc is written in there somewhere. Restart the terminal.
Run the install command.
Run the use command.
Now that Node.js and npm are installed, test them by typing
node -v and
Create a Project
At this point, you're set to start setting up Gulp, Webpack, Browserify, or whatever your aim is. We can also create a simple project to test that everything is working properly.
Navigate to the directory in which you want your project to exist - in my case, sites/node-test.
Now initalize a new project with npm.
The following will pop up in the terminal, and prompt you for a few
First, it will ask for a package name.
The rest you can just press enter and skip. Now you'll notice we have a package.json file that contains all the information we entered.
A package.json is a file that contains metadata about the project, and handles the dependencies (additional software and modules) of the project.
Now, we're going to install our first dependency - a very important and useful package called left-pad, which will add white space to the left side of a string, adding up to a number.
For example, writing this:
Will output this:
left-pad is a package on npm, which as we stated previously contains the registry for all publicly available packages.
To install a dependency with npm, we use the command
npm install dependency-name-here. Now, simply running
npm install will download the dependency, but it won't save it to the project. Since we've already created our package.json, we'll use the flag
--save to install the dependency and add it to package.json.
As long as you ran this command inside the project directory, it will successfully install the dependency by creating a node_modules directory. It will also create a package-lock.json file, which we can ignore. Finally, it updated our package.json file with a new line.
Now the project recognizes the left-pad dependency as existing
You can also run
npm install --save-dev to specify that the dependency will only be used for development (not production) purposes.
Run Node in the terminal
Let's create index.js in the root of our directory. This is everything you should have now:
For future reference, don't bother looking in the node_modules rabbit hole. It will get really overwhelming with bigger projects.
In order to use a dependency, we use
require() and put it in a variable, like so:
This will be the entirety of our index.js file, in which we require left-pad, run a
leftPad() function, and send it to the console.
Since Node.js is not recognized by the browser, we'll be testing this in the console. In your shell, run the
node command followed by the filename in the root of your project.
If everything went well, you should have printed
Hello, World! to the console, with two spaces on the left.
