Last updated Saturday, Nov 16, 2019 Setting up Node.js and npm on Mac OSX Node.js is gaining a lot of speed and is an exciting new development framework. Here's a quick overview of how to get Node.js working on OSX along with npm, the package manager for node.
What’s Node.js® and NPM?
Node.js® is a JavaScript-based environment which you can use to create web-servers and networked applications. You can also use it to perform helpful tasks on your computer such as concatenating and minifying JavaScript files and compiling Sass files into CSS.
NPM is a “package manager” that makes installing Node “packages” fast and easy. A package, also called a module, is just a code library that extends Node by adding useful features. For example, the “request” module simplifies the process of making HTTP requests so you can easily get web resources from other sites.
NPM is installed when you install Node.js®
Although there is a Mac installer program on the Node website, we recommend using Homebrew to install and update Node.
Prerequisites
- You should have some familiarity with the Mac Terminal application since you’ll need to use it to install and test Node and NPM. You’ll also need the Terminal to use Node.js and NPM. The Terminal application is located in the Utilities folder in the Applications folder.
- Dependencies. Although you can install Node in other ways, we recommend using Homebrew. Homebrew lets you avoid possible security problems associated with using the
sudo
command to install software like Node and Node modules.- Install Homebrew. Follow the steps on the How to Install Homebrew on a Mac instruction guide to install Homebrew.
Installation Overview
Installing Node.js® and NPM is pretty straightforward using Homebrew. Homebrew handles downloading, unpacking and installing Node and NPM on your system. The whole process (after you have Homebrew installed) should only take you a few minutes.
Installation Steps
- Open the Terminal app and type
brew update
. This updates Homebrew with a list of the latest version of Node. - **Type
brew install node
. - Sit back and wait. Homebrew has to download some files and install them. But that’s it.
Test it!
Make sure you have Node and NPM installed by running simple commands to see what version of each is installed:
- Test Node. To see if Node is installed, type
node -v
in Terminal. This should print the version number so you’ll see something like thisv0.10.31
. - Test NPM. To see if NPM is installed, type
npm -v
in Terminal. This should print the version number so you’ll see something like this1.4.27
How to Update Node and NPM
New versions of Node and NPM come out frequently. You can use Homebrew to update the software it installs.
- Make sure Homebrew has the latest version of the Node package. In Terminal type
brew update
- Upgrade Node:
brew upgrade node
How to Uninstall Node and NPM
You can use Homebrew to uninstall packages that it installed:
brew uninstall node
In order to use almost any development tools based in JavaScript, you'll need to know how to use npm and Node.js. Gulp, Grunt, and Webpack are a few examples of popular technologies you may have heard of that require a knowledge of the Node ecosystem.
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.
Prerequisites
- Basic command line proficiency. Don't skip this step! If you don't know how to use the command line, you'll be fighting an uphill battle. The provided tutorial has everything you need to know.
Goals
- Learn what Node.js and npm are
- Set up Node.js and npm on Windows and Mac
What is Node.js?
JavaScript is a client-side programming language, which means it’s processed in the browser. With the advent of Node.js, JavaScript can also be used as a server-side language.
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
-g
flag.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.All set.
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.
Open the
~/.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 npm -v
.All set.
Create a Project
![Node Node](/uploads/1/1/7/7/117734228/214990840.png)
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.
Initialize Project
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.
Version number.

Description.
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.
Install dependencies
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.Conclusion
In this tutorial, we learned the following:
- What Node.js is
- What npm is
- How to install Node.js and npm on Windows or Mac
- How to make a local project
- How to install a dependency with npm
- How to run a file using a node_modules dependency in a shell
If you got lost at any point, view the source on GitHub.
With this knowledge, you're ready to start using Gulp, Grunt, Webpack, Browserify, or anything else that depends on Node.js or npm.
