WHAT’s NPM?

Node Package Manager (NPM) serves as the primary package manager for Node.js, a runtime environment for JavaScript. Node.js facilitates the development of scalable applications within specified timelines. NPM is instrumental in installing, organizing, and distributing reusable code packages or modules written in JavaScript.

This platform enables open-source developers to exchange and utilize packages for application development, functioning as a command-line utility for package installation, dependency management, and version control within projects.

Key Components of NPM include:

  1. Website: The official NPM website serves as a repository for discovering packages pertinent to your project. Additionally, users can establish profiles to streamline package management and accessibility.
  2. Command Line Interface (CLI): The CLI provides a means to interact with NPM packages and repositories directly from the terminal of your computer.
  3. Registry: Housing an extensive database of JavaScript projects and associated metadata, the registry permits access to any supported NPM registry. Moreover, users have the option to leverage external registries subject to their terms of use.


Node.js is a renowned open-source JavaScript library and runtime environment that operates seamlessly across various platforms. Originally developed by Ryan Dahl in 2009, Node.js has evolved into a powerful tool for executing web applications independently of the client’s browser environment. Notably, the latest iteration, version 18, was unveiled in October 2022. Leveraging an asynchronous, event-driven architecture, Node.js stands out as an ideal framework for developing data-intensive server-side web applications.

It’s imperative for practitioners to remain abreast of the latest advancements, and Node.js version 19 facilitates this endeavor by providing access to cutting-edge features. Notably, as an odd-numbered release line, version 19 does not transition to long-term support (LTS) status. Detailed guidelines and release policies are available on the official Node.js GitHub repository.

Building upon the achievements of its predecessor, Node.js 20, the project recently introduced Node.js 21. With Node.js 20 graduating to LTS status, it will enjoy support until April 2026, while Node.js 21 assumes the role of the ‘Current’ release for the ensuing six months, concluding in April 2024.

Recent insights from the Stack Overflow Developer Survey 2022 underscore Node.js’ dominance as a preferred technology for web development. Notably, Node.js has emerged as the cornerstone of web development in the United States, powering over 6.3 million websites.

Central to Node.js’ efficacy is its support for the “Single Threaded Event Loop” architecture, enabling it to efficiently manage multiple concurrent clients. Rooted in the JavaScript event-driven model and callback mechanism, Node.js’ processing model is tailored for responsiveness and scalability.
