JavaScript has become a go-to language in the software development industry. The front-end developers aim to create feature-rich UI with JavaScript development and engage with back-end web services using AJAX. Since JavaScript offers non-blocking nature, web developers who work on the server-side have shifted their paradigm to JavaScript.
Nowadays, many front-end frameworks like TezJS, VueJS, React, Angular, etc., use JavaScript as their primary language. Thanks to its code optimization functionality. In fact, choosing JavaScript development services as your first option will surely bring plenty of opportunities to master a single language while still developing “full-stack” web applications. And the vital key to this server-side JavaScript revolution is NodeJs.
Now, let’s understand what Node.js is.
NodeJs is a cross-platform environment that runs and executes JavaScript codes outside the browser. It’s a version of Chrome’s V8 JavaScript runtime engine, allowing you to develop server-side JavaScript applications. It comes up with everything which is required to run a program written in JavaScript.
So, if you plan to install NodeJs and NPM in your system, we are here to guide you with detailed steps.
So, let’s get into the Node.js development guide of installation.
NPM
The NPM – Node Package Manager is the default package manager for NodeJs. Basically, NodeJs is a JavaScript runtime environment, allowing developers to develop the scalable application in a given time.
NPM allows open-source web developers to share and borrow packages for app development. Also, it works as a command-line utility for the application for installing packages in the project, dependency management, and even version management.
Components of NPM
1) Website: You can find packages from the official NPM website for your project. Also, you can create and set up profiles to manage and access all types of packages.
2) Command Line Interface (CLI): To interface with NPM packages and repositories, the CLI runs from your computer's terminal.
3) Registry: It has a huge database of JavaScript projects and meta-data. Thus, it allows you to use any supported NPM registry. Also, you can utilize someone else’s registry as per their terms of use.
What’s NodeJS
NodeJS is an open-source, cross-platform JavaScript library and runtime environment. You can use it to run web apps outside the client's browser. Ryan Dahl developed Node.js in 2009, and the latest version, v18, was released in October 2022. This IDE is used to develop server-side web apps, and since it uses an asynchronous, event-driven model, it is the best option for creating data-intensive apps.
According to the Stack Overflow Developer Survey 2022. NodeJS is the most popular web development technology. With a "Single Threaded Event Loop" architecture, NodeJS manages multiple concurrent clients at the same time. The Node.js processing model is built on the JavaScript event-based model, as well as the JavaScript callback mechanism.

After choosing the path, double-click to install .msi binary files to initiate the installation process. 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.
- By clicking on the Next button, you will get a custom page setup on the screen. Make sure you choose 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!
Step 3: Check Node.js and NPM Version
- If you have a doubt whether you have installed everything correctly or not, let’s verify it with “Command Prompt”.
Command Prompt window will appear on the screen.
To confirm Node installation, type node -v command.
To confirm NPM installation, type npm -v command.
And you don’t need to worry if you see different numbers than mine as Node and NPM are updated frequently.
In my case, the version of node.js is v14.15.3 and npm is 6.14.9.
How to Install Node.js and NPM on Mac?
Now, if you are using a macOS, let’s understand the process of Node.js and NPM installation.
