MEAN Stack vs MERN Stack: Detailed Comparison

Difference Between MEAN And MERN Stack

The main difference between the MERN stack vs MEAN stack is the MEAN stack is mainly utilized to manage files and abstraction in coding. Whereas, the MERN stack helps to code rapidly. In terms of productivity, MEAN wins, since, it is suitable to build large-scale apps. On the other hand, if your goal is to build small apps faster then choose the MERN stack. MEAN stack offers various ready-to-use features, whereas the MERN stack requires additional 3rd party libraries to support similar requests. Even, there is another difference between Full-stack vs MEAN stack that should be noted. The full-stack mainly refers to a developer who is aware of different programming languages, whereas the MEAN stack is a combination of web technologies considered a division of full stack.

Check this table for the basic difference.

Also, this another table will help you to understand the difference between the MEAN and MERN stack.

Below we have explained the MEAN and MERN stack along with their list of key features.

What is MEAN Stack?

MEAN stack is a popular web development framework that consists of four open-source technologies: MongoDB (database), Express.js (backend web framework), AngularJS (frontend web framework), and Node.js (runtime environment). This stack provides a powerful platform for developing full-stack web applications, with a strong focus on JavaScript as the primary programming language throughout the entire development stack.

The front end of the MEAN consists of Angular. It is a collection of JavaScript technologies to build scalable web applications. Client, server, database, the entire communication will be based on JavaScript. To build dynamic websites and applications, developers use rapid prototypes.

For example, developers build a prototype of a working web app for clients before developing the complete app using AngularJS.

You can also build multifaceted technology projects (projects consisting of varieties of technologies) using the MEAN stack. Even the newbie developers who are not aware of how to create a web application can also apply the MEAN tech stack for their development.

In-depth Breakdown of MEAN Stack vs MERN Stack

This in-depth comparison of the MEAN stack vs MERN stack development will help you to understand its core differences and help you to compare both web frameworks – Angular vs React.

1. Learning Curve

   MEAN Stack: For newbies, it might take some more time to learn the MEAN stack because it is a pre-configured framework.

   MERN Stack: MERN is relatively easy to use. ReactJS includes proper documentation for the developers to easily get all the information.

   Winner: MERN Stack

   Reason: MERN stack is the winner here because compared to the MEAN stack, you will get proper documentation and enough data to learn the tech stack easily.

2. Third-party Libraries

   MEAN Stack: By default MEAN stack includes HTTP requests and backend connections functionalities. So without having the knowledge of programming languages, you can easily use the libraries.

   MERN Stack: MERN stack is still evolving and does not have different libraries to fulfill all the project development. Additionally, React also requires additional settings to integrate the 3rd party libraries.

   Winner: MEAN Stack

   Reason: MEAN stack covers most of the backend and HTTP request functionalities by default, without tweaking the settings.

3. Performance

   MEAN Stack: Performance is crucial while choosing the right technology stacks. MEAN stack is a pre-configured framework. By selecting the MEAN stack, you will get slightly better performance than the MERN stack.

   MERN Stack: It uses virtual DOM instead of native DOM, due to that, needless rendering time increases. Apart from that, you will require to configure everything separately.

   Winner: MEAN Stack

   Reason: MEAN stack wins because it is the pre-configured framework and offers better performance than the MERN stack.

4. MVC Architecture

   MEAN Stack: If you are planning to apply the MEAN stack in large-scale projects, then consider Angular technology. Because the web application architecture of the MEAN stack’s user interface is independent of the intermediate layer. That’s why it is suitable for enterprise-level architecture.

   MERN Stack: On the other hand, the MERN stack solely depends upon JSX to write and add the HTML code in React. The MERN stack is flexible for small to large-scale projects. Unlike MEAN stack, which lacks scaling or project structure.

   Winner: MEAN Stack

   Reason: MEAN stack wins here because it supports the organized framework, and it is the most preferred framework for enterprise-level architecture.

5. Data Flow

   MEAN Stack: In the MEAN stack, UI and model can be altered depending upon your choice. Because the data flow of the MEAN stack is bi-directional.

   MERN Stack: React unidirectional data binding is more helpful if you plan to manage large-scale projects. You can even take the help of a MERN stack developer to build flexible web applications according to your requirements.

   Winner: Draw

   Reason: Both Angular and React have their own data flow and work perfectly depending upon the type of the project. For example, Angular’s bi-directional flow is suitable to handle small to large projects efficiently. At the same time, React’s unidirectional flow is more suitable for small-scale web apps.

6. Security

   MEAN Stack: MEAN stack is considered to have higher security than the MERN stack. MEAN stack is built using scalable frameworks like Node.js and Angular, which are supported by JSON Web Token (JWT). This tech stack secures unauthorized access to any resource to encrypt your sensitive data. Even to keep the cookie data on the client-side, you can implement cookie-based sessions.

   MERN Stack: The primary focus of the MERN stack is building an API backend along with Express, Hapi. Therefore, it becomes faster and straightforward in executing operations. When it comes to security, the MERN stack provides authentication methods, but these methods are ineffective against CSRF attacks.

   Winner: MEAN Stack

   Reason: MEAN stack provides strong security support to project the application against vulnerable attacks and helps to encrypt your personal data. It makes sure that all the session data stays on the client-side rather than keeping it on the server end.

7. Faster Development for Small Applications

   MEAN Stack: In the MEAN stack, it is easier for you to switch between servers and clients. If you are planning to develop real-time web apps, go for the MEAN stack.

   MERN Stack: MERN stack uses DOM, which helps developers to build web applications faster. Even the stable code of Reactjs uses unidirectional flow. If you are looking to build a small application using JavaScript, then choose the MERN stack.

   Winner: MERN Stack

   Reason: To build web solutions faster and in an efficient way, go for the MERN stack. Also, this framework helps to develop small applications faster and in an efficient way.

As you have learned about the in-depth difference between MERN and MEAN stack. You should also know the answers to the top most asked questions about the MEAN stack and MERN stack.
