MEAN Stack vs MERN Stack
Updated on 08th Apr, 21 391 Views

Application stack development has taken a whole new level since the last decade. Each web platform that we see on the Internet has two sides to it: One, the frontend, which is a visualization of data that is seen by the user, comprising web design and its interface. The backend functions in the background to manage the data that is seen by the user on the frontend. The backend comprises server-side programming and the database. The technology stack, on the other hand, indulges in a set of tools and frameworks to develop well-performing software.

In this blog, let’s discuss in brief about two widely used technology stacks and their differences:


MEAN Stack

MEAN Stack is a modern approach to Web Development. It can be termed as a collection of JavaScript-based Web Development technologies that assist in building robust websites and applications. MEAN is a free, open-source JavaScript framework with an extensive suite of built-in testing tools.

The video below will help understand the basic concept of MEAN Stack –

MEAN is short for MongoDB, Express.js, Angular.js, and Node.js. Let us have a look at each one of them:

A NoSQL document-based backend databaseA backend web application framework for APIsAn open-source frontend JavaScript framework for user interfaceA JavaScript-based run-time execution environment on the server-side
Stores high-volumes of data using documents and collectionBuilds single-page, multi-page, and hybrid-page applicationsAids the MVC design that can structure the web and business applications with easeDevelops networking and server-side applications
Saves the data in the binary JSON format and Extends cloud functionalitiesA node-based server layer that provides logic for the stack  Uses the HTML syntax while expressing various syntaxesForms web frameworks for I/O-based web applications

Advantages of Hiring a MEAN Stack Developer

A MEAN Stack Developer is an appropriate choice for speeding up the web or mobile app development process. Following are the advantages of hiring a MEAN Stack Developer:

  • MEAN Stack Developers cover the complete development process from the frontend (client-side) to the backend (server-side) of an application using JavaScript.
  • They include MVC architecture and lessen the hefty work, thereby smoothing out the process of development.
  • They work with prime technologies accordingly, i.e., they use MongoDB and Express.js to work on the backend whereas Angular.js and Node.js to work on the frontend.
  • They utilize the framework in such a way that it enables popular plugins and lessens the time taken for system administration.

Skill Sets a MEAN Stack Developer Must Possess

  • Be aware of cloud technologies, architecture, web designing, and integration
  • Knowledge of HTML and CSS
  • Understanding of SDLC and the Agile environment
  • Have access to multiple frameworks for web creation and development

Why choose MEAN Stack?

MEAN Stack is highly flexible toward code transfer within other frameworks. Using this, one can build a robust framework that supports daily needs. MEAN Stack is simple and easy to learn with good community support. It is preferred for small-to-medium-scale projects.

It extends over a full development cycle, from the client-side to the server-side. However, MEAN stack is ideal for powerful frontend development, preferably for enterprises that require single page-applications but with a dynamic user interface.

You can take a look at Intellipaat’s Full-Stack Web Developer Course which is a master program designed by Intellipaat to help create full stack web applications using the core technologies of MEAN.


MERN Stack

MERN Stack is a common alternative of MEAN Stack, where traditional Angular.js is replaced by React.js, which makes the development process much smoother and easier.

‘MERN’ is an acronym made up of a set of technologies, namely, MongoDB, Express.js, React.js, and Node.js. Let’s dig into what each of these components performs:

  • MongoDB: It is a cross-platform, document-oriented scalable NoSQL database. It is a flexible platform that enables users to create tables, schemas, and much more. Once MongoDB is installed, it comes along with Mongo Shell, which is a JavaScript interface that performs the querying, updating, and deleting of records. This database involves a simple environment setup and stores the application data.
  • Express.js: This is layered on top of NodeJS. It supports the backend framework and makes it simpler to write the backend code. It helps in designing better APIs and web applications. This modular framework also supports middlewares and promotes code reusability to ease the process of writing the code. It is specially designed to conduct simplified applications.
  • React.js: It is a frontend framework used for creating user interfaces. It is quick in handling rapidly changing data, simplifying the development of single-page and mobile applications. This JavaScript library lets developers create UI components and the interface of single-page web applications. It also enables them to edit and refresh the page without reloading it.
  • Node.js: It is a JavaScript run-time environment that allows users to run the code on the server. It supports Node Pack Manager (npm), which is a combination of thousands of public and private node modules that are free to download.

Advantages of Hiring a MERN Stack Developer

MERN Stack Developers can efficiently build web and mobile applications using standard processes and abilities. Below mentioned are a few add-ons on why to hire a MERN Stack Developer.

  • MERN Stack Developers implement design thinking with enhanced expertise on various technologies.
  • They maintain full-fledged development in the shortest time.
  • They focus on improvised solutions by maintaining compelling user experience and delivering highly scalable cloud integration.

Skill Sets a MERN Stack Developer Must Possess

  • Be proficient in HTML and JavaScript
  • Understanding of profiling applications and optimizing them
  • Knowledge of various databases and programming templates

Why choose MERN Stack?

When compared to Angular.js of the MEAN Stack, MERN Stack’s React.js is best for UI layer abstraction. It executes code development quickly due to its collection of dynamic user interfaces readily available within the library. MERN acts the best in controlling and updating large dynamic JSON data that can smoothly navigate between the frontend and the backend.


MEAN Stack vs MERN Stack

Now that you are familiar with both MEAN Stack and MERN Stack, let’s come to the topic of discussion: MEAN vs MERN. The presentation of their architecture will let you delve into the major differences between MEAN and MERN.

In both MEAN and MERN, all the above components are used as a combination for building a full-stack project. They offer opportunities for JavaScript Developers to build full-stack applications with an attractive interface for users to interact with, which enables the users to navigate through pages and respond to actions smoothly and quickly.


Difference Between MEAN Stack and MERN Stack

Similar to MEAN Stack vs Full Stack, MEAN and MERN also differ in its component alignment in their architecture: In MEAN, it is Angular.js, and in MERN, it is React.js. Though both Angular.js and React.js are used in organizing UI layers and carry ample documentation and sample codes, they cause a slight difference between MEAN and MERN:

MEAN StackMERN Stack
MEAN uses the AngularJS frameworkMERN uses the ReactJS library  
MEAN is backed by Google Inc.MERN is backed by Facebook Inc.
It exhibits a steeper learning curve  It is much simpler to learn
Angular.js has undergone major alterations from version 1 to version 2React.js performs better than Angular.js in maintaining UI rendering

It possesses ready-to-use features to support multiple third-party libraries  React.js requires additional libraries to support such calls
It offers better developer productivity  React offers lower developer productivity  
Data flow is bidirectional, i.e., when the UI is changed, the model state is automatically changed  Data flow is unidirectional, i.e., the UI can be changed only after changing the model state  
MEAN is suitable for handling small projects  MERN is more suitable for managing larger projects  

Things to Consider Before Choosing the Right Stack for Your Business

  • Project requirements: Analyze project requirements to check the feasibility of the stack
  • New practices: Introduce Agile development practices to experience a customer-driven market
  • Flexibility and feasibility: Note the differences between database architecture and software solutions to maintain flexibility
