A complete introduction of Node.js in 2023- TDTRG

As development is evolving, new frameworks and open-sourcing engines are replacing the previous ones. In this article, we will explore the features of Node.js. We will also examine some well-known companies that use Node.js and the situations where it may not be the best choice. Finally, we will discuss the future of Node.js and what to expect in the coming years.

What is Node JS framework?

Node.js is a powerful and versatile JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows developers to run JavaScript on the server side, creating server-side applications with JavaScript. This means that instead of using a language like PHP or Python for the server side, developers can use JavaScript, which is a language they are likely already familiar with from working on the front end.

It is commonly used for web servers, real-time applications, and network applications. Popular libraries and frameworks for Node.js include Express.js and Meteor.js.

Key attributes of Node JS framework:

Node.js has several key attributes that make it a popular choice for server-side development. One of the most important is its ability to handle multiple concurrent connections with high performance. Non-blocking, event-driven I/O model makes this possible.

Additionally, Node.js is lightweight, making it well-suited for building real-time applications, such as chat apps, and data-intensive applications, such as online games.

1.   Non-blocking, event-driven I/O model:

Node.js uses a non-blocking, event-driven I/O model, which means that it can handle multiple concurrent connections with high performance. This is due to the V8 JavaScript engine, which is built to handle asynchronous code. This model allows Node.js to handle a large number of connections without the need for additional threads, making it lightweight and efficient.

2. Built-in support for JavaScript:

Node.js allows developers to use JavaScript for both the front-end and back-end of an application. This eliminates the need to learn a new language for server-side development and allows for a more seamless development process.

3. Package management with npm:

Node.js comes with the npm package manager, which makes it easy to install and manage dependencies for a project. npm has a large and active community, which means that there are a wide variety of packages available for use.

Why Use Node.js?

1. Easy to learn:

Node.js is relatively easy to learn, especially for developers who are already familiar with JavaScript. This makes it a great choice for new developers and teams who want to quickly build server-side applications.

2. Scalability:

Node.js is highly scalable and can handle a large number of connections without compromising performance. This makes it well-suited for building real-time applications and data-intensive applications that need to handle a high volume of traffic.

3. Cross-platform compatibility:

Node.js can be run on a variety of platforms, including Windows, Linux, and macOS, and can be easily deployed to various cloud environments.

4. Microservices Architecture:

Node.js is a great choice for building Microservices architecture. Because of its lightweight and asynchronous nature, it can handle a large number of services running independently and communicating with each other.

5. Community Support:

Node.js has an active and growing community of developers who contribute to its development and provide support to other users. This ensures that the platform is always evolving and improving. All of these attributes contribute to making Node.js a powerful, versatile, and efficient runtime that is well-suited for building high-performance, scalable server-side applications.

Difference between Node and Node.js

Node and Node.js are often used interchangeably, but they refer to slightly different things. A node refers to the executable file that runs the JavaScript runtime environment on your computer. It allows you to run JavaScript code outside of a web browser and is used for server-side programming.

Node.js is an open-source, cross-platform JavaScript runtime environment that uses the V8 JavaScript engine developed by Google. It allows you to run JavaScript code on a server and is commonly used for building server-side applications, such as web servers and APIs.

In simpler terms, Node is the JavaScript runtime and Node.js is a platform built on top of Node that provides additional features and libraries for server-side programming. So Node.js is a runtime environment for executing JavaScript code on a server, while Node is the command you use to run that environment on your computer.

Companies Using the Node JS framework

Node.js is a popular choice for companies of all sizes, but some well-known companies that use it include Netflix, Uber, and PayPal. These companies have leveraged the performance and scalability of Node.js to build large-scale applications that handle a high volume of traffic.

Where shouldn’t the Node JS framework be used?

Node.js is not well-suited for CPU-intensive tasks, such as image or video processing. It may not perform as well as other languages in these cases. Additionally, Node.js is not ideal for building applications that require a high level of security, such as financial applications.

Express Framework in Node.js

Express.js is a popular web framework for Node.js. It is a minimal and flexible framework for building web applications and APIs. Express provides a thin layer of fundamental web application features, without obscuring Node.js features.

It provides a routing system that allows developers to handle HTTP requests and create endpoints for their applications. It also supports middleware, which are functions that run before or after an HTTP request is handled. This allows developers to add functionality to their applications, such as logging, authentication, and error handling.

Express also supports template engines, which allows developers to easily render dynamic HTML content. It also has support for handling form data and file uploads. Express is easy to learn and use, and it has a large and active community, which means there are many resources available to help developers create their applications. It is also well-documented and maintained. With express, you can easily build RESTful API and handle different types of HTTP requests like GET, POST, PUT, DELETE, etc. It also allows you to use middleware and handle errors easily.

Node.js prompts

In Node.js, prompts are used to get input from the user in the command line interface (CLI). There are several libraries available that can be used to create prompts, such as:

inquirer.js: A popular library for creating interactive command-line prompts. It provides a collection of common prompt types, such as input, confirm, list, and checkbox.

prompt: A simple library for creating command-line prompts. It provides basic prompt types, such as input and password.

enquirer: Another library for creating interactive command-line prompts, which has a similar API to inquirer.js.

CLI-prompt: a simple utility library to handle inputs from the command line interface.

Using these libraries, you can create prompts that ask the user for input, display a list of options for the user to choose from, or confirm an action.

Here is an example of creating a simple input prompt using the inquirer.js library:

const inquirer = require(‘inquirer’); inquirer.prompt([{ type: ‘input’, name: ‘name’, message: ‘What is your name?’ } ]).then(answers => { console.log(`Hello ${answers.name}!`); });

This code will display the message “What is your name?” in the command line, and wait for the user to enter their name. When the user enters their name and presses Enter, the code will log “Hello [name]!” to the console.

Future of node.js

The future of Node.js looks bright, with continued development and growing support in the community. New updates and features, such as the recent release of Node.js 15, aimed to improve performance and security. As the need for real-time and data-intensive applications continues to rise, Node.js will likely continue to be a popular choice for developers.


Node.js is a popular choice for companies of all sizes, and its future looks bright with continued development and growing support in the community. However, it’s not well-suited for CPU-intensive tasks and applications that require a high level of security.

Overall, Node.js is a great choice for developers looking to build high-performance, scalable web servers, and APIs, but it’s important to consider the specific needs of a project before deciding to use it. With its growing popularity, support, and continued development, Node.js is an excellent option for many projects and will likely continue to be a popular choice for developers in the future.
