How to Install Npm And Node.jS on Windows and in MAC?

Quick Summary

Node.js is an open-source, cross-platform runtime for executing JavaScript code outside browsers, widely used for building back-end services by major companies. NPM (Node Package Manager) is a free, open-source library and registry for JavaScript packages, offering command-line tools for package installation and dependency management. Node.js and NPM installations on Windows involve downloading the installer, selecting options, and verifying versions, while on Mac, Homebrew simplifies the process with a single command.

What is Node.JS

An open-source, cross-platform runtime environment called Node.js allows JavaScript code to be executed outside a browser. NodeJS is neither a programming language nor is it a framework. Back-end services like APIs for web apps and mobile apps are built with Node.js. Big corporations like Paypal, Uber, Netflix, Walmart, and others use it in manufacturing.

What is NPM?

npm stands for Node Package Manager. It’s a library and registry for JavaScript software packages.

npm also has command-line tools to help install the different packages and manage their dependencies.

npm is free and relied on by over 11 million developers worldwide. You could say it’s kind of a big deal. They’re open-source and have become the center of Javascript code sharing. There are more than a million packages available on npm.

In short, npm is:

• An online repository for the publishing of open-source Node.js projects
• A command-line utility for interacting with the said repository, helping with installing packages, and managing package versions and dependencies

• The Microsoft 365 and Office Resources website lists the software requirements for various Office products, including Office Standard, Office Professional Plus 2019, and Office 2019 for Mac Standard.

Installing Node and NPM in Windows

Since we’ve chosen to use Node.Js to construct an application, you must first install Node.Js on your Windows computer.

We will now walk you through the installation procedure step-by-step. Now, let us begin with the initial step.

Download the Installer

Download the Windows Installer from NodeJ’s official website. Make sure you have downloaded the latest version of NodeJs. It includes the NPM package manager.

The LTS (Long-term Support) version is highly recommended for you. After downloading the installer package, install it with a double-click on it.

Now .msi file will be downloaded to your browser. Choose the desired location for that.

Install Node.js and NPM

After choosing the path, double-click to install .msi binary files to initiate installation. Then, give access to run the application.

You will get a welcome message on your screen and click the “Next” button. The installation process will start.

• Choose the desired path where you want to install Node.js.
• You will get a custom page setup on the screen by clicking on the Next button. Make sure you choose the npm package manager, not the default of Node.js runtime. This way, we can install Node and NPM simultaneously.

You should have 143MB of space to install Node.js and npm features.

The following features will be installed by default:

• Node.js runtime
• Npm package manager
• Online documentation shortcuts
• Add to Path
• Bang! The setup is ready to install Node and NPM. Let’s click on the Install button so hard!

Check the Versions

After the installation, you can verify that Node.js and NPM have been installed successfully by opening a command prompt or PowerShell window and typing the following commands:

node -v

npm -v

This will display the installed versions of Node.js and NPM.

Installing Additional Tool

If you want to install additional tools globally, you can use npm. For example, you might want to install the Node.js package nodemon for automatic server restarts during development. To install nodemon globally, use the following command:

npm install -g nodemon

The -g flag installs the package globally, making it available from any directory.

Installing Node and NPM in Mac

Download the .pkg Installer

Click on the “macOS Installer” option to download the .pkg installer. Make sure you download it to your desired location.

Run Node.js Installer

Now, your installer is ready to run. However, it will not take you much time. So, let’s explain in detail here.

Introduction > Continue License > Select Continue > Agree Installation Type > Install > Authenticate with your Mac to allow the Installation > Install Software Summary > Close

Verify Node.js Installation

To verify whether you have properly installed Node.js in your macOS, run the following command in your terminal:

Node -v node -v // The command we ran – tests the version of Node.js currently installed v12.13.0 //Node.js installed. It can be some other version.

Update Your NPM Version

Node.js doesn’t automatically update the version of npm.

Write a given command, and your npm version will be updated.

$ sudo npm install npm –global // Update thenpmCLI client

Tadda! Node.js is there on your Mac system. Interesting, right? Let’s explore it further.

How to Install NPM on Mac using Homebrew

To install Node.js and NPM on a Mac using Homebrew, follow these steps for How to Install NPM on Mac:

Install Node.js and NPM

Once Homebrew is installed, you can install Node.js and NPM. Open your terminal and run the following command:

brew install node

This command installs both Node.js and NPM. It might take some time to download and install the packages.

Verify Node.js and NPM Installation

After the installation, you can verify that Node.js and NPM are installed by checking their versions. Run the following commands in your terminal:

node -v

This command should output the installed Node.js version.

npm -v

This command should output the installed NPM version.

Conclusion

Node.js empowers developers to run JavaScript outside browsers, facilitating the creation of robust back-end services. NPM, a crucial companion, is a free, open-source package manager with vast code-sharing capabilities. Whether on Windows or Mac, the installation processes are user-friendly, opening doors to a world of JavaScript development possibilities. In the realm of Node.js Development Company, expertise in harnessing the power of Node.js is essential for creating scalable and efficient server-side applications.
