NodeJS Libraries

Websites are an online medium benefitting the users in the everyday cycle. Because of its growing demand, businesses look for web development solutions to avoid disorder in website functionality.

This is where NodeJS libraries come as a supportive hand. The open-source runtime environment has become popular among website developers because of its flexible codes, module functions, and cross-platform compatibility.

Due to an array of reasons, the Node.js framework is preferred for website development in general. However, there are diverse options in its library’s modules with its unique functionality and integral structure for developing a Node.js web app.

So as you move further, you will understand the top NodeJS libraries and their features in this blog.

But first, let us understand the background of Node.js.

What is Node.js?

Node.js is an open-source runtime environment built on JavaScript in 2009. It contains an abundant library that applies to cross-platform web apps. Being used for server-side (backend) development, the program is impeccably suitable for handling bulk data applications.

This software package is event-driven with non-blocking elements for asynchronous data streaming. Because Node.js is being constructed on engine V8 JavaScript, the JS framework is compiled into machine code for speedy development.

Generally, many concurrent requests need to be handled all at once. This can potentially slow down the speed and performance. Here, Node.js provides relief with its event-driven, non-blocking I/O model. Moreover, its large ecosystem consists of packages (Node Package Manager) and NodeJS libraries reduces the difficulty of the development process. That is why several businesses hire dedicated Node.js developer to build flawless web apps, online games, and more.

Top 6 Features of Node.js Libraries


Node.js being an open-source framework avails all the libraries without any cost. The JavaScript environment is compatible with any platform in a way where the libraries can be used by the community, providing more resources and code execution in the projects.

Non-Blocking Elements and Asynchronous

The NodeJS library has a default asynchronous function that entails non-blocking elements for streamlining events through APIs. The API handles a client’s request by evaluating if it contains any data interaction. If it has none, the API reverts the request to the client and proceeds with the next request. This is how all the requests are streamlined.

High-Speed Performance

Node.js runtime environment is set up on the JavaScript’s V8 engine, established by Google Chrome. The JS engine motor compiles the code into machine code that speeds up the deployment adeptly. Moreover, the asynchronous function enables to acceleration of the code functioning.


Because of its asynchronous and single-threaded loop, the Node.js app allows multiple requests simultaneously. To this extent, it efficiently handles the requests and reduces the loading issues in real time.

Single-Threaded Loop

The workflow of Node.js operates on a single-threaded loop, a structured way of handling events (defined responses of API requests). This single loop leverages asynchronous data by streaming multiple requests at a time. Besides, it performs input-output tasks on different threads to enable non-blocking operations.

Event-Driven Architecture

The core architecture is event-driven to deal with the events. These events are referred to as a module that consists of an ‘EventEmitter’ class for operating event handlers. These handlers are a function called during a triggered event. Later, the loop catches the triggers and commands the event handler.
