Node.js is a run-time environment used for executing JavaScript outside the browser. Npm is a JavaScript package manager commonly used for installing packages for Node.js.

In this article, you will learn how to install Node.js and npm on Mac or Linux. You will also learn how to verify the installation, run Node.js code, and how to update Node.js and npm.

When you’re finished, you’ll be able to run Node.js code on Mac or Linux computer.

Prerequisites

To follow this tutorial successfully, you’ll need the following:

Internet access to download Node.js.
Basic knowledge of how to use the terminal.

Step 1 — Install Node.js and npm on Mac or Linux

There are a couple of ways to install Node.js on Mac or Linux. The most recommended method and also my favorite method to install Node.js and npm is to use Node Version Manager(nvm).

Using nvm has the following benefits:

It allows you to install multiple versions of Node.js.
It makes it easy to switch between the versions.
Updating node.js is a breeze with nvm.

So let’s now install nvm. Copy and paste the command below into your terminal.

Info: If your on Mac, open your ~/.bash_profile or create a new one if the ~/.bash_profile file does not exist. Make sure you add source ~/.bashrc in the file and save.

Now let’s verify if nvm was installed successfully.

Your terminal should display the current version of nvm. At the time of writing, the current version is 0.35.2. So this is the output I got.

Note: On Linux, if you get nvm: command not found or no feedback, close your terminal and open a new terminal and enter the nvm --version again. Reddit ableton crack mac. If you using ssh to access linux, you might need to restart your session.

Tip: On Mac, if you are having any issues with the nvm command not working, check out this link

Lets now install Node using nvm’s install command.

Once installed, set the installed version as the default.

Info: You need to set the default version because nvm forgets the node version in a new terminal session. You can learn more about the issue here.

Step 2 — Verify Node.js and npm installation

Verify if Node.js and npm were successfully installed.

Type node -v. It will display the current Node.js version.

Type npm -v to display the current npm version.

Your output should look similar to mine. Note that the versions will be different since you might be reading this tutorial when new versions came out.

Running Node.js Code on Mac or Linux

There are two ways to run Node.Js code:

Node.js REPL
Running Node.js scripts on the terminal

Node.js REPL

REPL stands for Read-Evaluate-Print-Loops. It is an interactive shell that allows experimentation of JavaScript code. It works the same way as the web browser console.

To access the Node REPL, type node in the terminal.

To exit out of the REPL, type .exit or press CTRL+D once. You can also exit out by pressing CTRL+C twice.

Running Node.js Scripts on the Terminal

This method is the one that is commonly used to run Node. You will write Node.js code in a file with an extension of .js and run it in the terminal using the node command.
