MEAN Stack vs MERN Stack: A Comparison

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

Choosing the correct technological stack, whether you’re a company’s IT expert or an entrepreneur planning to create online and mobile apps, is a challenge. You may have come across a comparison between the MEAN stacks and MERN stacks in this context.

The digital world is constantly changing, and we are witnessing several technological developments and new market demands on a daily basis. As a result, in this digital age, having an app or a website is not the only method to expand your company. You must be astute in choosing the appropriate technology stack for your project.

Choosing the correct technological stack for your company will also have an impact on its future development. Should you use the MEAN stack or the MERN stack? Which one will be more beneficial to your company? To gain answers to these issues, you must first understand the fundamentals of these two, such as their distinctions, similarities, and benefits.

So, first and foremost, let’s introduce the MEAN and MERN stacks!

What is MEAN Stack, and how does it work?

This is a full-stack technology stack that is quite popular. MongoDB, Express.js, Angular, and Node.js are the acronyms for MongoDB, Express.js, Angular, and Node.js, respectively. This stack is used by programmers to create mobile and online apps. MEAN is a JavaScript-based open-source technological stack. This stack is useful for MEAN stack developers who want to build mobile and web apps quickly because it includes key plugins and tools.

The Advantages of Using MEAN Stack

  • It is less expensive. The MEAN stack is open-source in every component, lowering development expenses.
  • Open-source JavaScript-based Angular provides reusability, maintainability, testability, and quick performance.
  • It’s open-source and cloud-compatible.MongoDB lowers the cost of transmitting cloud services inside the app’s circular region.
  • The MEAN stack makes it simple to move between server-side and client-side operations. JavaScript developers that wish to write code quickly and easily will find this to be quite beneficial. JavaScript is a programming language that developers must be knowledgeable with in order to handle the complete project.

What exactly is MERN Stack and how does it function?

Another open-source tech stack that can be classified as full-stack is this one. MongoDB, Express.js, ReactJS, and Node.js are the acronyms for MongoDB, Express.js, ReactJS, and Node.js. With it, you can create hybrid mobile and online apps.

The MERN stack was intended to make the development process go more smoothly. It’s a collection of frameworks, databases, and runtime environments based on JavaScript. This software stack gives MERN stack developers an end-to-end framework, and it’s growing in popularity.

The Advantages of Using MERN Stack

  • Set up with a lot of help from the community.
  • Pre-installed is a complete suite of testing tools.
  • The React library offers high-end app development capabilities. Developers may use the library to create web apps for free.
  • It supports the model view controller (MVC) architecture for a seamless development process.
  • Developers must be familiar with JavaScript and JSON in order to use this JavaScript stack.
  • This tech stack comprises both front-end and back-end development processes, thanks to JavaScript.
  • Developers may utilize React codes on both browsers and servers.
    This JS stack enables the server-side generation of pages as needed.

Which is more popular, MEAN vs MERN?

You must pick a popular tech stack, and choosing the right stack increases your chances of employing experienced engineers because more developers are likely to be familiar with it.

The popularity of Angular vs. React stacks, in turn, fosters the rise of MEAN vs. MERN stacks. Despite its popularity, React is currently overtaking Angular.

According to the HackerRank Developer Skills Report for 2020, 32.3 percent of developers want to learn to React in 2020, making it a very popular choice. Angular’s market share has fallen to 27.6%, showing that React is becoming more popular than Angular.

The 2019 StackOverflow Developer Survey report confirms that React is becoming more popular. According to this study, roughly 74.5 percent of developers favor React. Angular, with a proportion of 57.6%, has a comparable percentage.

Both React and Angular are very popular. In the long run, though, you’ll find it simpler to employ React programmers than Angular developers.

A Comparison of MEAN Stack with MERN Stack

The use of Angular and React, respectively, is the main distinction between the MEAN and MERN stacks. Both stacks have some beneficial and negative aspects to them.

1. Curve of Learning

Node.js, MongoDB, and Express.js are all widely used and have extensive documentation.

Regardless, the learning curve for React and Angular will differ.

Templates and Typescript are used in the Angular framework. With Angular, you may find a steeper learning curve, whereas, with React, there isn’t much of one.

2. Financial viability

Because both MERN and MEAN stacks use Node.js, Express.js, and MongoDB, a profitability comparison between the two would expose the difference between React and Angular.

Because Angular is a comprehensive framework, it is more profitable. In most cases, you’d leverage React-related third-party libraries to improve designer productivity.

The CLI (Command Line Interface) in Angular increases the efficiency of designers. And you’ll find that using the Angular CLI makes it easy to refactor your code. Because of the presence of third-party libraries, updating your React code requires additional effort.

3. Information Flow

The data flow in Angular is bidirectional, which means that whenever you make a change to the user interface, the model state is instantly updated. In the case of React, data flow is one-way only. So, if you’re using React, you can only change the UI after changing the model state.

React’s unidirectional data binding provides a better data overview, which makes huge projects easier to manage. As a result, the MERN stack is better suited to large projects.

If you’re working on a tiny project, Angular’s bidirectional data binding becomes the more efficient option. MEAN stack comes in handy here!

4. Third-Party Assistance

Using third-party libraries while developing enterprise-level apps is another important consideration. MEAN includes Angular, which offers built-in functionality for HTTP calls and integration with the backend.

Alternative libraries for bringing incomparable features are available in ReactJS. 

5. Code Management and Upgrades

The MEAN stack makes dealing with and upgrading your code easier, which is a benefit of using Angular. Angular can help the MVC architecture by being a well-organized and full framework.

Using an intermediate layer, you can easily isolate database-related code from UI-related code, making it easier to manage and upgrade your code. Due to the inclusion of third-party libraries, managing and upgrading the React code requires additional effort.

6. Development of Mobile Apps

Angular provides the Ionic framework for mobile app development company, which allows you to create hybrid mobile apps. Because you just have one codebase for both iOS and Android platforms, these apps keep development costs low. Hybrid applications, on the other hand, fall short of the native user experience.

React Native is a little different in this regard. The MERN stack is a preferable solution for mobile app development since it gives an almost-native user experience.

7. Checking

An angular app tester’s experience differs from a React app tester’s experience. In general, this will influence your choice between the MEAN and MERN stacks. You can simply test an Angular project with just one tool, such as Jasmine.

This is not the case with a React app, which will necessitate the use of numerous technologies. To test the JS code, you’ll need to use a tool like Jest and to test the elements, you’ll need to use a tool like Enzyme. When creating a React project, you’re likely to use a lot of third-party libraries, so your testing effort is impressive.

8. Scalability and security are other important factors.

MERN and MEAN stacks both provide best-in-class security. As a result, you have the option of selecting any of them.

9. Large-Scale Apps

The MEAN stack is an excellent choice if you’re working on an eCommerce project. It can serve as the foundation for dynamic web apps and introduce a more streamlined method to prototyping. For constructing large-scale apps on MEAN stack development frameworks, I prefer the MEAN stack.

10. User Interface Requirements

Do you want your app’s UI to be basic but sophisticated? Then use the MERN stack to achieve your goal. It can instantly generate a frame and display it on the screen, ensuring a smooth user experience.

11. Development Team Expertise and Experience

Supporting documentation isn’t as important if your development staff is very knowledgeable and skilled with web frameworks. In this case, the learning curve is less suitable, allowing you to choose the MEAN stack.

If your development team has a modest amount of experience, you must consider the learning curve, thus the MERN stack is a better choice.

12. MVC Compatibility

If you’re working on an enterprise-level project, you’ll need to keep track of the entire architecture. This is why the MEAN stack, not the MERN stack, should be used.

Selecting this option will allow you to benefit from the Model-View-Controller architecture. The MEAN stack, on the other hand, is a good choice if you want to keep the code simple.

13. Apps for CRUD

The MERN stack makes it simple to construct and develop a CRUD (Create, Read, Update, and Delete) app from start to finish.

The use of React allows for quick data changes and a nice user interface. MERN is an excellent framework for creating a mobile app or a single-page app.

14. Prevention of Defects

The MEAN stack is the ideal option for you if you want to select a stack that allows you to prevent simple coding errors. Angular uses Typescripts, a system that prevents simple code errors during the development phase.

15. Long-Term Maintenance and Improvement

Both React and Angular are widely used frameworks. However, as React grows in popularity, it will become easier to find React developers in the future.

Consider using the MERN stack if you have a huge pipeline of app improvement work and expect considerable long-term maintenance demands.

16. Exercising

Angular is used in the MEAN stack to update the real DOM (Document Object Model). The Document Object Model (DOM) is an XML/HTML programming interface.

MERN, on the other hand, relies on React to refresh the virtual DOM. As a result, MERN allows you to code apps more quickly.

As a result, no framework can address every business goal. To acquire a better result and achieve your business goals, you must do a study on each feature, match them with the fast MERN stacks development needs, and select intelligently.

Aside from the benefits supplied by both stacks, there are some differences between them. Let’s get right to the point to wrap things up!


The close competition between the MEAN and MERN stacks makes it difficult to pick between the two or justify both. Both technologies, after all, have best-in-class functionality and capabilities. To create a dynamic app, choose the MEAN or MERN stack based on your company’s needs.
