MERN stack is extremely popular and a strong stack to work in. If you are able to build and deploy a great MERN application, it can help in your career prospects as a developer.

What is the MERN Stack?

To create a web application combination of technologies used is referred to as Stack. For creating any web application multiple technologies such as framework, libraries and databases are used which form basis of MERN stack.

MERN stack is a JavaScript stack designed to make development process smoother and easier. MERN includes four open source components- MongoDB, Express, React & Node.js. These components offer end –to end framework for developers to work in.

 MERN Stack Components


MongoDB is a cross-platform document database. Further it is a NoSQL (non-relational) document-oriented database.

Conventional relational databases have a typical schema design based on columns and tables; MongoDB on the other hand is schema-less.

Data is stored in flexible documents with JSON (JavaScript Object Notation)-based query language. The content, size, and number of fields in the documents can vary from one to the other. This implies that the data structure to be altered over time. This database is known for being flexible and easy to scale.


Is a back-end web application framework. Express is a web application framework for Node.js which is another MERN component. Express is used to simplify the task of writing server code instead of writing full web server code by hand on Node.js directly. You don’t need to repeat the same code over and over, as you would with the Node.js HTTP module.

The Express framework is intended for building robust web applications and APIs. It’s well-known for its quick speed and minimalist structure, with many features available as plug-ins.


React is a JavaScript library used for building user interfaces. It is open sources but was originally created by a software engineer at Facebook. Currently, it is maintained by Facebook, as well as a community of development companies and individual developers.

React library can be used for creating views deliver in HTML. React views are declarative. This means that you don’t have to worry about managing the effects of changes in the view’s state or changes in the data.

Instead of depending on templates to automate the creation of repetitive HTML or DOM elements, it uses a full-featured programming language (JavaScript) to build recurring or conditional DOM elements. With React, you can run the same code can run on both the server and the browser.

It anchors the MERN stack. In a way, it’s the central feature of the stack. It’s the one component that tells apart MERN from MEAN.


Node.js is a cross-platform JavaScript runtime environment. It was initially built for Google Chrome and afterwards open-sourced by Google in 2008. It is built on Chrome’s V8 JavaScript engine. It’s created to build scalable network applications, and can perform JavaScript code outside of a browser.

It works without an enclosing HTML page, in its place using its own module system based on CommonJS, to put together several JavaScript files.

Advantages of the MERN Stack

The main benefit for developers by means of the MERN stack is that every line of code is written in JavaScript. It is a programming language which is used everywhere, both for client-side code and server-side code. With the assistance of one language across tiers, there’s no need for context switching.

With tech stack with several programming languages, developers have to work out how to interface them collectively. With the JavaScript stack, developers only need to be capable in JavaScript and JSON.

On the whole, using the MERN stack facilitates developers to build highly competent web applications.
