MERN Stack Vs. MEAN Stack: A Comparison Between the Two Tech Stacks

MERN Stack Vs. MEAN Stack: A Comparison Between the Two Tech Stacks
12/12/2022 57

In the early days of computers, when websites were small and simple enough for one person to handle all facets of web development, the term "full stack developer" was first used. However, since some of these early days, the web has developed to a higher level of sophistication. Technology, predictive computing, and responsive design have made it so that a single programmer can no longer design and build an app or website from start to finish. However, it is now challenging but not impossible. According to research by HackerRank Development Skills, 30% of developers polled said they knew about Angular, making it the most well-known web platform in the development community. But only 26% of developers said they knew React, which put it in second place.

MEAN and MERN are two of the most popular technology stacks used to build websites and online software. Should you use the MEAN stack or the MERN stack, then? Which option will be more effective for your company? The choice will determine everything, including how long it will take to develop your app, who you'll need to recruit, and what it could do.

What would be the main distinctions between any of these stacks, then? Which one would you pick based on your needs? Let's take a closer look at each of these to see what they are made of and how they help make apps.

What is MERN Stack?

The MERN application programs are used to create the prototype of full-stack software. A technological stack is a collection of platforms and tools that help programs grow. MERN emerges for Node.js. React, MongoDB, and Express.js. In this arrangement, Express and Node.js are used to construct the backend. React is used to develop the front end, while MongoDB generates the database. When paired with Node.js, MongoDB, and Express.js, React transforms a Java-based software solution into an extraordinarily versatile and open-source platform. Numerous renowned companies, including Uber and Netflix, have implemented the MERN stack.

MERN stack developers may create whole webpages (and apps) by combining React with JavaScript, TypeScript, and other user-facing features on the front end with Node JS on the application server (backend). JavaScript is currently preloaded in many new apps. Therefore, MERN Stack has already gained prominence and is expected to be heavily used in the future.

MERN Stack- Main Components

  • Document-based NoSQL database management MongoDB.
  • Express.js: A server-side application platform for creating hybrid, single-page, and multi-page web apps.
  • React is a front-end JavaScript toolkit that is free and open source for creating interface designs built on UI components.
  • Developed on Chrome's V8 JavaScript, Node.js is a cross-platform default setting for JavaScript used to execute backend programs.

MERN Stack- Features

  • Runs over Several Servers: MongoDB can run across multiple servers. The data is copied to maintain the system and ensure the technology breaks down.
  • Purely JavaScript-based: Context switching is unnecessary because just one expression is used throughout. The consumer and the web-based application's data center are developed using JavaScript.
  • Dynamic Database: With a flexible data structure, variable schema, a strong GUI, and function tools, programmers may quickly create original applications.
  • Smooth UI Rendering: When it comes to UI layer simplification, React JS is ideal. React also allows you to develop the application and better arrange the code because it is a library.

Why Use the MERN Stack?

  • Makes it easier to use the model-view-controller operator (MVC) architecture for efficient web development.
  • Real-time testing using a wide range of already built-in tools.
  • Offers a component-based design that may be reused to speed up development.
  • React-based code is compatible with servers and browsers. It gives developers the freedom to build webpages on the servers as necessary.
  • Includes front-end to the backend design process from start to finish.

What Is Mean Stack?

A JavaScript-based programming framework called MEAN Stack. The initials of the four technologies employed here are combined to form the name "MEAN." A JavaScript-based architecture for building web apps is called the MEAN stack. The four primary components of the stack are Node Angular, MongoDB, and Express. Thus, the abbreviation MEAN.

MEAN Stack- Main Components

Node.js, Express, MongoDB, and Angular are described as MEAN. Let's assess them individually:


A server-side run-time processing context for javascript Creates networking and server-side software I/O-based services and forms-based Web platform.


A platform for API-empowered back-end web applications Frames combination, multi-page and single page. A node-based website server component that serves as the function of stack.


In a server-side document-based NoSQL server Extreme volume content utilizing gathering and records is stored Information is stored in binary JSON format and expansion in internet functionality.


The enabled front-end javascript user experience library MVC design is supported making commercial and online development easy Using the HTML syntax several syntaxes are expressed.

While express is a Node.js platform, Angular would be a client-side Javascript library, and Node serves as a JavaScript-based web server; MongoDB is involved with content databases in this scenario. The MEAN brand growth consists of these mentioned techniques. This stack is generally employed in the creation of web applications.

Although highly flexible, the MEAN stack has a very specialized application. Mean stack shines in some areas, but it also has several places where it is not advised. As a result, the MEAN stack is suitable for cloud-native, mobile, and similar applications due to its scalability. Additionally, the MEAN stack developer provides strong concurrent user management capabilities.

MEAN Stack Functionality

  • JavaScript use: Enables users to cut back on unused internet usage. It renders the functionality of web apps more effective.
  • The solution: MongoDB, a secure NoSQL database tool that simplifies the process of inserting, updating, and deleting data.
  • Websites powered by Node.js load faster. To avoid unheard-of user bounces, the Node.js event-driven framework serves databases quicker than the Apache server.
  • Isomorphic code: enables server-side (browser) and client-side execution (NodeJS). Due to MEAN's adaptability, code may quickly move to another platform while maintaining functionality.

Reasons to use MEAN Stack

  • It includes the entire web development lifecycle, from client-side to server-side.
  • MEAN supports the MVC (Model - view - controller Switch) architecture, which makes creating web apps streamlined and simple.
  • Provides a wide range of web app functional testing that is already designed.
  • Consists of open-source technology and has strong community backing.
  • Due to its low cost, it is perfect for SMEs and new enterprises.

In general, the front end of such a stack AngularJS platform is intended to construct single-page applications (SPAs). MEAN stack is hence effective for developing single-page applications. Web apps for news, calendars, and maps are a few examples.

MERN vs MEAN Stack- Core Points of Difference

Generally speaking, a "stack" is a combination of technologies, software tools, and computer languages. Stacks are often broken up into two main groups: application stacks and technology stacks.

Email, databases, and Microsoft Word would be included in the application stack's core functions. Conversely, a technology stack lists the many technological services required to operate a program. The most popular technological stacks are MERN Stack and MEAN Stack. Let's take a closer look at MERN Stack vs. MEAN Stack.

MEAN vs MERN- Changes in UI Framework

The UI surface elements are organized and rendered using the best possible code by both Angular JS and React JS. Both possess access to a vast knowledge base of tutorials, sample scripts, and information. Consequently, this essay dissects the assessment into numerous variables to aid you in making a decision.

Finally, AngularJS has released its stable releases. From phase 1 to version 2, Angular JS underwent significant modifications and, at first, was somewhat shaky. Today, nevertheless, it continues to be a solid JavaScript-based MVC framework. It enables more excellent abstractions in your programming and improved file management. React JS, on the other hand, allows you to write code more quickly. React JS also outperforms Angular JS despite only being a library.

MEAN stack vs MERN Stack- How to choose for varying projects?

In this section, we've addressed elements impacting the decision between React JS and AngularJS, which is the main distinction between MERN Stack and MEAN Stack. Let's get to the point right away to wrap things up;

Enterprise-level Designs: The MEAN stack would be the best option if you want to construct a corporate app or an e-commerce application. It provides a systematic approach for creating prototypes and serves as the framework for all interactive web programs.

But if you need a straightforward, refined, yet attractive UI representation for your app, it would be best to choose MERN.

Niche Projects: Using the MERN Stack, developers may create and deploy whole CRUD applications. React provides an appealing user experience while making it simple to manage sudden changes in data for MERN stack developers. MERN is ideal for small applications, whether a smartphone version or a single-page app.

From the in-depth evaluation of both tech stacks, it is clear that no strategy is the panacea. Analyze all the characteristics, map them to the demands of rapid development, and then make a considered decision based on the requirements for your project of app development.

MERN Stack vs MEAN Stack- A Detailed Comparison

Compared to Full Stack versus MEAN Stack, MERN and MEAN differ in their platforms' component conformance: in MEAN, Angular.js is used, whereas, in MERN stack development services, React.js is. Even though React.js and Angular.js would be utilized to arrange UI layers and represented with complete information and sample scripts, they produce little difference between MERN and MEAN.

Since both standards provide reliable security at the UI level, the rivalry among MEAN and MERN stacks remains relatively tight. While the MERN stack employs the ReactJS library, a Facebook product, the MEAN stack uses AngularJS, which is supported by Google Inc. By using JavaScript as the principal programming language, code-switching is avoided. New developers are given the tools necessary to materialize their concepts.

Both alternatives offer a fantastic set of capabilities that may be used to create software solutions that work effectively. Therefore, selecting the appropriate stack for their programs might be overwhelming for newbies. Let's take a deeper look at how they performed in various scenarios.

MERN Stack- What are its benefits?

Given our financial data, we can do a credible assessment of the future developments that MERN stack programmers will experience. Pay is also determined by experience, skills, and the firm. What advantages does knowledge of the MERN Stack provide developers?

The main advantage of adopting the MERN stack for programmers is that every single line of code is authored in JavaScript and JS, a language used for client-side and server-side applications.

Designers have to find out ways to integrate different programming languages. Developers using stack just need to be knowledgeable in JavaScript and JSON. Generally speaking, web application developers may create incredibly efficient apps by utilizing the MERN stack.

  • Come pre-built with a broad range of technology tools.
  • A component that renders itself and keeps its state is the fundamental React building piece, how it is rendered: a factor that describes the status of the data and the display. The developers may concentrate on the design and logic of the program by breaking the application up into components.
  • Feasibility of mentioned techniques: express, MongoDB, react, node.js.
  • Enables model view controller design to facilitate seamless development.
  • React's code is compatible with websites and users because it can operate on the latter.
  • The MERN Stack uses only open-source, accessible technology.
  • Once more, the MERN stack spans the entire developmental cycle, from frontend to backend programming.
  • Use javascript to cover the whole web development lifecycle, from frontend to backend programming. You must be knowledgeable about JSON and javascript.
  • MERN stack offers the MVC architecture and simplifies project development obstacle-free.
  • The MERN Stack includes several built-in, proprietary testing tools.

Mean Stack- What are its benefits?

When it comes to transferring code to different frameworks, MEAN Stack is quite adaptable. It may be used to create a strong structure that can sustain daily demands. With robust community support, MEAN Stack is straightforward to understand.

It encompasses the entire development cycle, from client to server. On the other hand, the MEAN stack is perfect for solid frontend development, ideally for businesses that want single-page apps but with a dynamic user interface.

The most significant benefit of using MEAN Stack is this. The MEAN stack-developed web application may be installed directly on the server. When compared to similar features, this server deployment feature has the potential to be highly useful. Clients strongly favour MEAN stack design solutions for several reasons, including this.


The biggest worry from the client's viewpoint is the price. It also doesn't help that the cost of creating web applications has risen. But here is where MEAN stack may be of assistance.

This JavaScript stack would be not only quick and efficient but also reasonably priced. Here are some of the factors contributing to its high demand.


A skill that is highly prized in the field of construction and the technology sector at large is adaptability. And the development of the MEAN stack includes something like this. It has been made possible by JavaScript's inherent agility. Despite this, the MEAN stack is highly adaptable and agile, providing a wealth of new options for clients and developers.


MEAN.js is not only less expensive but also time-efficient. This stack has a fast development rate and requires minimal production time, primarily because of the standard language and convenient resource availability. Everyone knows that money is valuable in the business world and that things that take less time to do are more affordable (usually).

MEAN vs. MERN Stack- how do they differ?

Because of its MVC architecture, the AngularJS platform is already well-known among AngularJS programmers. MVC design, however, might not always be necessary for a web application. Some web applications require a UI layer separation to optimize the component presentation code. A library that fills this need in React JS.

The usage of the Angular JS frameworks and the React JS library, respectively, is the primary distinction between the MEAN & MERN stacks. Deciding on MEAN and MERN might be difficult because both frameworks are focused on delivering UI-level abstraction.

React JS is a creation of Facebook Inc., whereas Google Inc supports angular JS. As a result, each of them enjoys the support of influential business people. The next part goes into great depth on choosing which tech stack is ideal for your requirements.

MEAN Stack
