This distro reached end of life (EOL) on Apr 2021.

We recommend upgrading to a more modern version. Read upgrade instructions.


Node.js is a JavaScript platform for general-purpose programming that allows users to build network applications quickly. By leveraging JavaScript on both the front- and back-end, development can be more consistent and designed within the same system.

In this guide, we’ll show you how to get started with Node.js on an Ubuntu 16.04 server.

If you are looking to set up a production Node.js environment, check out this link: How To Set Up a Node.js Application for Production.


This guide assumes that you are using Ubuntu 16.04. Before you begin, you should have a non-root user account with sudo privileges set up on your system. You can learn how to do this by completing steps 1-4 in the initial server setup for Ubuntu 16.04.

How To Install the Distro-Stable Version for Ubuntu

Ubuntu 16.04 contains a version of Node.js in its default repositories that can be used to easily provide a consistent experience across multiple systems. At the time of writing, the version in the repositories is v4.2.6. This will not be the latest version, but it should be quite stable and sufficient for quick experimentation with the language.

In order to get this version, we just have to use the apt package manager. We should refresh our local package index first, and then install from the repositories:

  • sudo apt-get update
  • sudo apt-get install nodejs

If the package in the repositories suits your needs, this is all you need to do to get set up with Node.js. In most cases, you’ll also want to also install npm, which is the Node.js package manager. You can do this by typing:

  • sudo apt-get install npm

This will allow you to easily install modules and packages to use with Node.js.

Because of a conflict with another package, the executable from the Ubuntu repositories is called nodejs instead of node. Keep this in mind as you are running software.

To check which version of Node.js you have installed after these initial steps, type:

  • nodejs -v

Once you have established which version of Node.js you have installed from the Ubuntu repositories, you can decide whether or not you would like to work with different versions, package archives, or version managers. Next, we’ll discuss these elements along with more flexible and robust methods of installation.

How To Install Using a PPA

An alternative that can get you a more recent version of Node.js is to add a PPA (personal package archive) maintained by NodeSource. This will have more up-to-date versions of Node.js than the official Ubuntu repositories, and allows you to choose between Node.js v4.x (the older long-term support version, which will be supported until April of 2018), Node.js v6.x (supported until April of 2019), and Node.js v8.x (the current LTS version, supported until December of 2019).

First, you need to install the PPA in order to get access to its contents. Make sure you’re in your home directory, and use curl to retrieve the installation script for your preferred version, making sure to replace 8.x with your preferred version string (if different):

  • cd ~
  • curl -sL -o

You can inspect the contents of this script with nano (or your preferred text editor):

  • nano

And run the script under sudo:

  • sudo bash

The PPA will be added to your configuration and your local package cache will be updated automatically. After running the setup script from nodesource, you can install the Node.js package in the same way you did above:

  • sudo apt-get install nodejs

To check which version of Node.js you have installed after these initial steps, type:

  • nodejs -v

The nodejs package contains the nodejs binary as well as npm, so you don’t need to install npm separately.

npm uses a configuration file in your home directory to keep track of updates. It will be created the first time you run npm. Execute this command to verify that npm is installed and to create the configuration file:

  • npm -v

In order for some npm packages to work (those that require compiling code from source, for example), you will need to install the build-essential package:

  • sudo apt-get install build-essential

You now have the necessary tools to work with npm packages that require compiling code from source.

How To Install Using NVM

An alternative to installing Node.js through apt is to use a specially designed tool called nvm, which stands for “Node.js version manager”. Rather than working at the operating system level, nvm works at the level of an independent directory within your home directory. This means that you can install multiple, self-contained versions of Node.js without affecting the entire system.

Controlling your environment with nvm allows you to access the newest versions of Node.js and retain and manage previous releases. It is a different utility from apt-get, however, and the versions of Node.js that you manage through it are distinct from the distro-stable version of Node.js available from the Ubuntu repositories.

To start off, we’ll need to get the software packages from our Ubuntu repositories that will allow us to build source packages. The nvm script will leverage these tools to build the necessary components:

  • sudo apt-get update
  • sudo apt-get install build-essential libssl-dev

Once the prerequisite packages are installed, you can pull down the nvm installation script from the project’s GitHub page. The version number may be different, but in general, you can download it with curl:

  • curl -sL -o

And inspect the installation script with nano:

  • nano

Run the script with bash:

  • bash

It will install the software into a subdirectory of your home directory at ~/.nvm. It will also add the necessary lines to your ~/.profile file to use the file.

To gain access to the nvm functionality, you’ll need to log out and log back in again, or you can source the ~/.profile file so that your current session knows about the changes:

  • source ~/.profile

Now that you have nvm installed, you can install isolated Node.js versions.

To find out the versions of Node.js that are available for installation, you can type:

  • nvm ls-remote
... v8.5.0 v8.6.0 v8.7.0 v8.8.0 v8.8.1 v8.9.0 v8.9.1 v8.9.2 v8.9.3 -> v8.9.4 (Latest LTS: Carbon)

As you can see, the newest LTS version at the time of this writing is v8.9.4. You can install that by typing:

  • nvm install 8.9.4

Usually, nvm will switch to use the most recently installed version. You can explicitly tell nvm to use the version we just downloaded by typing:

  • nvm use 8.9.4

When you install Node.js using nvm, the executable is called node. You can see the version currently being used by the shell by typing:

  • node -v

If you have multiple Node.js versions, you can see what is installed by typing:

  • nvm ls

If you wish to default one of the versions, you can type:

  • nvm alias default 8.9.4

This version will be automatically selected when a new session spawns. You can also reference it by the alias like this:

  • nvm use default

Each version of Node.js will keep track of its own packages and has npm available to manage these.

You can have npm install packages to the Node.js project’s ./node_modules directory by using the normal format. For example, for the express module:

  • npm install express

If you’d like to install it globally (making it available to the other projects using the same Node.js version), you can add the -g flag:

  • npm install -g express

This will install the package in:


Installing globally will let you run the commands from the command line, but you’ll have to link the package into your local sphere to require it from within a program:

  • npm link express

You can learn more about the options available to you with nvm by typing:

  • nvm help

Removing Node.js

You can uninstall Node.js using apt-get or nvm, depending on the version you want to target. To remove the distro-stable version, you will need to work with the apt-get utility at the system level.

To remove the distro-stable version, type the following:

  • sudo apt-get remove nodejs

This command will remove the package and retain the configuration files. These may be of use to you if you intend to install the package again at a later point. If you don’t want to save the configuration files for later use, however, then run the following:

  • sudo apt-get purge nodejs

This will uninstall the package and remove the configuration files associated with it.
As a final step, you can remove any unused packages that were automatically installed with the removed package:

  • sudo apt-get autoremove

To uninstall a version of Node.js that you have enabled using nvm, first determine whether or not the version you would like to remove is the current active version:

  • nvm current

If the version you are targeting is not the current active version, you can run:

  • nvm uninstall node_version

This command will uninstall the selected version of Node.js.

If the version you would like to remove is the current active version, you must first deactive nvm to enable your changes:

  • nvm deactivate

You can now uninstall the current version using the uninstall command above, which will remove all files associated with the targeted version of Node.js except the cached files that can be used for reinstallment.


As you can see, there are a quite a few ways to get up and running with Node.js on your Ubuntu 16.04 server. Your circumstances will dictate which of the above methods is the best idea for your circumstance. While the packaged version in Ubuntu’s repository is the easiest, the nvm method is definitely much more flexible.
