Node.JS Development Trends in 2021

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. It uses an event-driven, asynchronous, non-blocking input/output model and operates on a single thread event loop. Node.js represents a “JavaScript everywhere” paradigm, unifying web application development around a single programming language, rather than different languages for server-side and client-side scripts.

Node.JS lets enterprises stay away from the complex inter-silo dependencies. With Node.js, frontend and backend teams can work as a single cohesive team to enhance the efficiency of your web development processes.

Why use Node.js

The popularity of Node.js has grown significantly in recent years because of its extremely lightweight and high flexibility. Node.js comes with an extensive library of JavaScript modules that simplify the development process. Due to its open-source nature, Node.js has become incredibly popular for both web and mobile application development.

Node JS Development Trends to Watch Out in 2021


GraphQL enables developers to design API calls with queries, schemas, and resolvers based on specific data requirements. Due to designing the endpoints according to the view in the application using REST API, it can create a bottleneck when the application needs quick iterations on the frontend.

Rise of MERN Stack

MERN stack is creating a niche in the development phase and this is because of certain advantages. As every single line of code is written in JavaScript it eliminates the need for context switching. MERN stack is creating a niche in the development phase and this is because of certain advantages. As every single line of code is written in JavaScript it eliminates the need for context switching. Traditionally tech stacks consisted of different programming languages used together. Developers faced a daunting challenge to seamlessly navigate across different frameworks.

Real-Time Apps

Real-time apps for online activities are the center stage of Node Js development. With a high level of user-engagement, real-time apps provide a set of advanced features, as well as speed. These apps include features such as chats, social media integration, ad servers, stock exchange features. Node.js fits all the requirements in this ecosystem.

Serverless Architecture

Node.js is known for its serverless architecture. This effectively means that in order to create an application there is no hassle of maintaining the servers. A serverless architecture greatly reduces dependency on hardware and servers, minimizes the cost of development. One of the biggest advantages is code quality and greater flexibility.


If you are looking to build enterprise grade projects, it is important to leverage Microservices which are instrumental in supporting the serverless approach. Microservices offers a vast array of benefits when it comes to performance and debugging by splitting different aspects of your application into separate services. Node.js makes it relatively easier for you to use microservices for your projects.


Node.JS provides real-time strength and data-centric approach which forms a good fit for developing Internet of Things (IoT) applications. Node.js lets you implement microservices to track features of geo-distributed systems in a real-time manner.


Node.js is one of the top JavaScript frameworks with its benefits constantly growing with the support of its huge community. If you would like to leverage the powerful features of this technology to realize your web development goals, get in touch with a leading Node.JS web development company.
