Introduction

Node.js and NPM are two of the most popular tools used for developing web applications. Node.js is a JavaScript runtime environment that allows you to run JavaScript code on the server side, while NPM is a package manager that helps you manage and install packages for your Node.js applications. Installing Node.js and NPM on Mac is a relatively straightforward process, and in this guide, we will walk you through the steps.

How to Install Node.js and NPM on Mac

1. Download the Node.js installer from the Node.js website.

2. Run the installer and follow the on-screen instructions.

3. Open a terminal window and type node -v to confirm that Node.js is installed.

4. Type npm -v to confirm that NPM is installed.

5. You can now use Node.js and NPM to develop applications.

Introduction

Node.js is a popular back-end JavaScript runtime used for creating web servers and scalable network apps. The environment supports server-side scripting – producing dynamic content for web pages before they are served to the user.

NPM is a package manager for JavaScript and the default package manager for Node.js. As such, NPM is installed alongside Node.js as a recommended feature.

This tutorial will show you how to install Node.js and NPM on Mac using the Homebrew package manager.

Prerequisites

Access to the terminal
Administrative level privileges

Note: Node.js has a PKG installer for macOS available on its website. However, installing with Homebrew is the recommended approach.

Install Homebrew

1. To install Homebrew on macOS, browse to Homebrew’s official website and copy the link displayed on the page.

How to Install Node.js and NPM on Mac

Installing Node.js and NPM on Mac is a relatively straightforward process. Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a browser. NPM is a package manager for Node.js packages, or modules if you like. In this tutorial, we will show you how to install Node.js and NPM on a Mac.

Step 1: Download Node.js

The first step is to download the Node.js installer from the Node.js website. Go to https://nodejs.org/en/ and click on the “Download” button. This will download the Node.js installer to your computer.

Step 2: Install Node.js

Once the download is complete, double-click on the .pkg file to start the installation process. Follow the on-screen instructions to complete the installation. Once the installation is complete, you should be able to open a terminal window and type “node -v” to check the version of Node.js that is installed.

Step 3: Install NPM

NPM is installed with Node.js, so you don’t need to install it separately. To check the version of NPM that is installed, open a terminal window and type “npm -v”. This will output the version of NPM that is installed.

Conclusion

In this tutorial, we have shown you how to install Node.js and NPM on a Mac. Installing Node.js and NPM is a relatively straightforward process, and once it is complete you can start using them to develop applications.
