Often there are various technology stacks that developers and programmers work on. If you are an entrepreneur, and wondering which technology stack should I use for my next project. Then let me tell you that there are popular tech stacks out there that will help you in this endeavour. Firstly, a technology stack is something that is going to be the backbone of your development project. It is something that you will use to guide and employ as well as deploy your project on. Secondly, the technology stack matters to you because your web or mobile app will be inheritantly using the features that your technology stack provides. In this blog we are going to discuss MEAN vs MERN to know which one is better for your project.

What is a STACK?

A stack is the technology vertical that encompasses the all round spectrum of application development. It mostly refers to the verticals that are used to develop different applications on. A typical application involves Front end technologies, databases and back end technologies used to develop the application. What does comes to your mind when you first hear about the word stack:

It is a piece of technology that helps drive the application development process and is going to have different features that support the process. The most common term used is Full Stack development. This term is used to define the ability of developers to work in any spectrum of technology. These can be front end, data management or database handling role or backend role.

The ability of developers to work and adapt to any technology depending on their skill set and expertise are full stack developers. Full stack developers can fit into any spectrum of development be it front end development, database handling or any back end development.


What is MEAN?

MEAN stands for Mongo DB, ExpressJS, Angular, and NodeJS. These four form the technology stack that is used. MEAN can be used for developing applications which helps to be scalable and dependable when it comes to using Angular. You can develop mostly web applications using this technology stack, These applications are easily scalable and provide robust performance when you use it.

MEAN is used when the type of applications you need to develop are not native. Mostly when it comes to using technology stacks, these stacks enable you to only develop hybrid applications that run in the browser of the mobile or smartphone device. It does not require you to download any kind of software package in order to run the applications. Hire MEAN Stack Developer for your next project.

What is MERN?

MERN stands for MongoDB, Express, React, And NodeJS. The only replacement being instead of using Angular, ReactJS is used.

Applications developed using react are known to be scalable and fast performance driven, Of course, you can only develop hybrid applications when using these technology stacks. Developers can easily code the interfaces needed to support the applications.

Due to the inclusion of react, your applications will be able to use open source technologies. Which means you do not require any kind of license or expensive subscription fees to be paid for using these technologies. You can Hire MERN Stack Developer for your project development.


MEAN Stack Features


There are several technologies that are part of the MEAN stack. MEAN stands for MongoDB, Express.js, Angular, and Node.js.


  • Reduced website loading time: 

Using Node.js event-driven architecture prevents visitor bounces because databases are rendered faster than with Apache server.


  • Uses Javascript: 

By using JavaScript, users can reduce unnecessary bandwidth usage. While enhancing the performance of web applications.   


  • Using MongoDB as a rescue: 

MongoDB is a classified noSQL database program that eases inserting, updating, and deleting data.


  • Using MEAN’s Isomorphic Code: 

Both client- and server-side code can run on the same machine. The flexibility of MEAN allows a swift switch to another framework without losing functionality.


  • Use of AngularJs: 

The AngularJS framework is a front-end JavaScript framework for developing single-page applications. The framework includes templates, dependency injection, and directives that make it possible to develop interactive user interfaces.


By combining these technologies, a full-stack web application can be built entirely in JavaScript, a single programming language.


MERN Stack Features


The MERN stack is a bundle of web application development technologies. It is an abbreviation for MongoDB, Express.js, React, and Node.js.


  • Multiple servers: 

MongoDB is compatible with a variety of servers, and the data is duplicated to ensure the system runs in case the hardware fails.


  • Based exclusively on JavaScript: 

There is no need to switch contexts, since JavaScript can be used to develop both server-side and client-side applications.


  • Data Model: 

With dynamic schemas, robust GUIs, and command-line tools, developers can quickly build customized applications.


  • UI Layer Abstraction: 

React JS has a great UI layer abstraction, and since it is a library. You have more freedom to build an application and organize the code more efficiently.


  • React:

With React, developers are able to build complex, interactive user interfaces. It utilizes a virtual DOM (Document Object Model) to minimize necessary DOM manipulations.

The MongoDB, Express.js, Node.js, and React, when combined, provide a full-stack solution for developing online applications. Allowing for the use of a single programming language (JavaScript) throughout the development process.

Differences between MEAN and MERN (MEAN vs MERN)



MEAN stack operates in the javascript category. It is a framework that drives development operations. The language used here is typescript, as the angular technology is used. As angular is coded using typescript it becomes the main language used for coding the applications.

When you use this technology stack, the learning curve borned by developers is going to be medium, this is because angular is an exhaustive technology to learn and there is going to be many concepts that developers need to master. It will take some time for your developer to get hands-on experience in knowing all the facts and concepts easily as well as implementing these concepts in the applications being developed.

The application architecture used by MEAN is component based. The data binding taking place when developing applications using MEAN stack are both one way and two way supported. It depend on the developer which data binding method that they want to use- one way or two way. Programmers and developer interact with the regular browser DOM or document object model. there is no concept of a virtual DOM here, so any changes that are made will be happening to the browser’s DOM only.


The category that MERN operates is the open source JavaScript library. The language used here is good old javascript. There are many developers who are familiar using javascript and hence there should be no problem for developers to use javascript. This is because React is developed using javascript and hence because React is used here. It becomes the main and official language to use for development purposes. The language used here can be a combination of JavaScript and JSX.

Because React offers a lesser learning curve compared to angular for MEAN stack, it becomes possible for developers to master concepts easily and efficiently. Also because react is used here, it becomes easy for developers to grasp concepts. This is much easier than angular, as React has a lesser learning curve compared to angular. MERN does not have any kind of app architecture. The data binding provided by MERN stack is supported by only one way, there is no two way binding support as provided by MEAN here. However there is support for virtual DOM, and the app changes are reflected to the virtual DOM. Instead of the browsers DOM, and this changes can be easily reflected to the browsers DOM. Once the changes are finalized, they can be sent to the browsers DOM.
