It is one of the hot topics to discuss because it is the most popular technology these days. MERN Stack offers an end-to-end framework to make the whole development process comparatively easier. It helps developers to make complex applications and also beginner-friendly for a newbie. 

The MERN stack is a JavaScript-based web development stack that consists of MongoDB, Express.js, React.js, and Node.js. 

In this article, we’ll explore the basic information about MERN stack for web development, and its benefits including its scalability, flexibility, and ease of use.

What is MERN Stack?

The MERN stack is a JavaScript-based stack for developing web applications. It consists of MongoDB, Express, React, and Node.js. It is one of the trending stacks for web development. Developers love it because it is easy to use and provides a great deal of flexibility. Additionally, the MERN stack is very versatile and can be used for developing a wide range of applications.

The MERN stack is a JavaScript-based web development stack that enables developers to create full-stack web applications using a single programming language, JavaScript. The MERN stack consists of four main components: MongoDB, Express, React, and Node.js.

MongoDB is a database that stores data in JSON-like documents. It offers strongly consistent reads and writes through application control over dummy sets. Read and write performance improves significantly as nodes are added in this. 

Express.js is a framework that runs on top of Node.js and provides the backend for web applications. 

React.js is a front-end JavaScript library that provides the user interface for web applications. It uses a JavaScript library for making UI which Facebook builds. It helps to build large application data that constantly changes with time.  

Node.js is a JavaScript runtime environment that executes code on the server side. It quickly creates network applications. Node’s javascript is primarily composed of an event-driven architecture using non-blocking data to minimize elevation and a built-in HTTP server framework for hosting web applications.

The MERN stack enables developers to create full-stack web applications using only JavaScript. This makes it simple to develop and deploy web applications as there are only a few technologies to learn and use. Additionally, the MERN stack is open source, which means that it is free to use, and there is a vast community of developers who contribute to its development.

Advantages of MERN Stack

There are several reasons why you should choose the MERN stack for web development. Some of the advantages of using the MERN stack include:

Easy to use

The MERN stack is easy to use and learn. A vast community of developers is always willing to help beginners. Additionally, the documentation for the MERN stack is excellent and easy to follow.


It is very flexible. You can easily add or remove components according to your needs. Additionally, you can also use a variety of programming languages with the MERN stack.


Many applications can be built using MERN, including e-commerce websites, social media platforms, Virtual Reality apps, and more.

Large Community

With apps like Uber, Airbnb, Instagram, Netflix, and Zomato, the technology stack has influential community support that makes sure you can always find solutions.

Code Maintenance

With MERN stack development for your web apps, you get easy code maintenance and error fixing, making it a cost-effective option. It also comes with powerful testing tools.

Why choose the MERN stack?

There are many reasons to choose the MERN stack for web development. The main reasons are that the MERN stack is a full-stack JavaScript solution, which means you can use one language (JavaScript) for both the front end and back end of your web application. This can make development faster and more straightforward, as you don’t have to switch between languages.

The MERN also includes some of the most popular and influential technologies available today, such as React and Node.js. These technologies are used by many of the biggest companies in the world, so you can be confident that they’re robust and reliable.

The MERN stack is an excellent choice if you’re looking for a modern, full-featured stack for web development.

MEAN Stack vs MERN stack – How to choose one?

There are some key differences between the MERN stack and the MEAN stack. For one, the MERN stack uses React for its frontend framework instead of AngularJS. Additionally, the MERN uses MongoDB for its database instead of MySQL.

Both Angular JS and React JS are committed to organizing the UI layer components and making them use the best code. Both of them are supported by outstanding command of documentation, sample codes, and tutorial videos. Hence, in order to help you choose the best for your project, let’s compare both.


Finally, AngularJS has come up with its stable versions. At first, Angular JS was fairly unstable and had to go through some major changes and launch version 2. 

But now, it remains stable as an amazing JavaScript-based MVC framework. It helps you to incorporate better concepts in your coding and manage files in a superior way. On the other hand, React JS helps developers to develop code much faster. Furthermore, being solely a library, the performance of React JS is far better than AngularJS.


A big company would always choose MEAN stack instead of MERN. The main reason behind this is the architecture. It is just a library which simplifies UI rendering. Alternatively, AngularJS is a well-crafted framework to support an MVC architecture where the database and UI code are separated with a middle part. This makes it easy to upgrade and manage code. Thus, the MEAN stack is an excellent choice for Enterprises.

So which stack is best for your project? 

Well, that depends on your specific needs and preferences. The MERN stack might be a better fit if you’re looking for a more modern stack focusing on simplicity. However, the MEAN stack might be a better option if you need something more robust and feature-rich.


The MERN stack is a great option for those looking to get into web development. The blend of technologies in MERN Stack makes it worthy for developing a wide range of apps and allows fast and easy distribution of apps. Since MERN developers know all its four components, it is also an affordable development process.
