Major Point of Difference Between MEAN and MERN Stack


Whether you are an IT expert or an entrepreneur with ambitions to build online and mobile apps, choosing the proper technology stack can be challenging. In this regard, you may come across the difference between the two most popular stacks, MEAN and MERN.

However, at every moment, you may see the digital transformation. Also, you may witness many technological developments and new market needs. In this digital age, having an app or a website is not the only way to grow your business. You should take the help of an appropriate technology stack for your project. Choosing the correct technological stack for your company will influence its future development. So, whether using the MEAN stack or the MERN stack is beneficial? We will cover the answer to this question in this detailed article.

MEAN Stack: Meaning

It is a full-stack and widely used technological stack. MEAN comprises MongoDB, Express.js, Angular, and Node.js technologies. However, many programmers use this stack to create mobile and online apps. Furthermore, MEAN is a JavaScript-based open-source technological stack that assists developers in fast developing mobile and online programs. Thus, to learn in-depth about this stack, it is necessary to undergo extensive training from the MEAN Stack Training Institute in Gurgaon.

MERN Stack: Meaning

This is also an open-source technology stack that comes under full-stack development. MERN is the full form of MongoDB, Express.js, ReactJS, and Node.js. With these four technologies, you can create hybrid mobile and online apps. However, the MERN stack makes the development process easier. Moreover, MERN is a collection of JavaScript frameworks, databases, and runtime environments that offers developers an end-to-end framework and is gaining immense popularity. Therefore, to become more familiar with this stack, we suggest you go through the MERN Stack Development Training in Gurgaon for a more advanced approach to achieving your goals.

Point of Difference between MEAN & MERN Stack

The basic difference between MERN and MEAN Stack is the inclusion of technology, Angular, and React. Some other distinction points are as follows:

     ● Learning Curve

Node.js, MongoDB, and Express.js are well-known frameworks with extensive documentation. However, the learning curves of MEAN and MERN differ in no sense. Nonetheless, the learning curves for React and Angular will change.

You may use templates and typescripts in the Angular framework. Also, Angular may have a great learning curve. On the other hand, React does not have a steep learning curve.

     ● Profitability

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

As Angular is a comprehensive framework, it is more profitable. In general, third-party libraries with React deliver reduced designer productivity. Also, Angular has a CLI (Command Line Interface), which increases designer productivity.

     ● Data Flow

In the case of Angular, the data flow is bidirectional, which means that if you change the UI, the model state will automatically change. On the other hand, the data flow is unidirectional in the case of React. So, if you utilize React, you can only change the UI after changing the model state.

However, React’s unidirectional data binding provides a better data overview, which helps to manage huge projects. Moreover, the MERN stack is better suitable for managing big projects.

So, if you’re working on a small project, Angular’s bidirectional data binding becomes a more efficient way, and the MEAN stack comes in very handy here.

     ● Third-Party Support

While developing enterprise-level apps, another crucial element to consider is the use of third-party libraries. MEAN includes Angular, which means functionality for handling HTTP calls and connecting to the backend.

Moreover, ReactJS provides other libraries for performing comparable functionality. MEAN handles third-party extensions in a plug-and-play manner, whereas MERN requires extra setups to do the same.

     ● Managing & Upgrading the Code

With the benefits of using Angular, the MEAN stack eases handling and upgrading your code. Angular, being a well-organized framework, may help the MVC design.

All you have to do is use an intermediary layer to isolate the database-related code from the UI-related code. This makes it simple to manage and upgrade your code. On the other hand, with the presence of third-party libraries, updating and upgrading the React code need more effort.

     ● Mobile App Development

For mobile app development, Angular provides the Ionic framework. It allows you to create hybrid mobile apps. Angular applications keep development costs minimal because there is only one codebase for iOS and Android platforms. Despite this, hybrid programs degrade the native user experience.

However, React Native is a little different in this regard. It gives an almost-native user experience. As a result, the MERN stack is a preferable choice for mobile app development.

     ● Testing

An angular app tester’s experience differs from that of React app tester. Generally, this will influence your choice between the MEAN stack and the MERN stack. You may test an Angular project using only one tool, such as Jasmine.

However, it is not the case with a React app, which will necessitate the usage of several technologies. With React, you need to use a tool like Jest to test the JS code. Also, you might need to use Enzyme to test the elements. Moreover, you will most likely use several third-party libraries while creating your React app.

      ● Scalability & Security

MERN stack and MEAN stack both provide best-in-class security. As a result, you can select any of them as per your choice. However, MERN wins the game in terms of security since it is more scalable than MEAN.


Hopefully, you may find this article informative. We have compiled the crucial points that specify the major difference between MERN and MEAN stacks. So, if you ask us to pick between the two, we will recommend that you choose the one that best meets your company’s needs, as they offer nearly identical functionality.
