10 Most Popular NodeJS Frameworks of 2021

Every year, we share with you the most popular NodeJS frameworks available, that make developers’ work so much easier. Just as a quick reminder, Node.js a.k.a. NodeJS, was first introduced in the year 2009 and is in itself a cross-platform framework built on Chrome’s V8 JavaScript engine.


In turn, a web application framework is a combination of libraries, helpers, and tools that provide a way to easily build and run web applications. So, in this situation, Node.js is used to build fast, highly scalable event-based network applications that do not block the input/output model, asymmetric single-threaded programming.


Every web framework lays the foundation for building a website/application, and its most important aspects are architecture and features (such as customization support, flexibility, extensibility, security, compatibility with other libraries, etc.).


The popularity of a web framework is important because it is an indicator of whether it will continue to be maintained, and what resources are likely to be available in terms of documentation, add-on libraries, and technical support.


However, JavaScript-based frameworks like NojeJS are even further simplified by using frameworks of their own. As a result, in this article, we are going to talk about some Node.js frameworks specifically, that will make working with Node.js easier and more pleasant.


So, let’s have a look at the 10 Most Popular NodeJS Frameworks of 2021. Note that this list is not organized in any particular order.


1. Express.js

Express.js is a Node.js web application framework that provides a robust set of features for web and mobile applications. It is designed for a developer to develop, build and run web apps quickly. It is a standard for most Node.js applications today.

Express.js features and benefits:
  • Write handlers for requests with different HTTP verbs at different URL paths (routes).
  • Integrate with “view” rendering engines in order to generate responses by inserting data into templates.
  • Set common web application settings like the port to use for connecting, and the location of templates that are used for rendering the response.
  • Add additional request processing “middleware” at any point within the request handling pipeline.


Based on the number of high-profile companies that use Express, the number of people contributing to the codebase, and the number of people providing both free and paid-for support, Express is a popular framework!


2. Koa.js
