Technology StackMEAN stack components include:

  • MongoDB
  • Express
  • AngularJS
  • Node
MERN stack components include:

  • MongoDB
  • Express
  • ReactJS
  • Node
Flow of DataMEAN stack includes bidirectional data flow. This means, in both directions, the data flow takes place.MERN stack includes unidirectional. In this, the view can only be updated using one way.
DOM (Document Object Model)Regular DOM is a concept of a structured text. DOM is a text of HTML code; here, the elements of HTML will take place as a node in DOM. JavaScript supports DOM.The virtual DOM (VDOM) is a programming concept in which a library like ReactDOM keeps an ideal, or “virtual,” representation of a user interface in memory and syncs it with the “actual” DOM.
Learning CurveTo learn Angular in MEAN stack, you need to learn everything related to MVC and typescript. Also, the MEAN stack contains vast libraries that take a significant amount of time to grasp.On the other hand, React does not have huge libraries to learn. Therefore, it is not challenging to learn.

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

What is MEAN Stack?

The MEAN stack application architecture consists of:

M: MongoDB
E: Expressjs
A: AngularJS
N: Nodejs

You may have glanced at the architecture of the MEAN 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 for the newbie developers who are not aware of how to create a web application can also apply MEAN tech stack for their development.

FeaturesIntroductionExplanation
JavaScriptJavaScript is the dynamic web programming language. It is a commonly used programming language to develop websites and games.JavaScript solves the problem of decreasing bandwidth usage. This, in turn, helps to reduce needless bandwidth usage.
Node.js DrivenNodejs is a backend JavaScript runtime environment based on the V8 engine that is open-source.You may be surprised to know that Node.js renders databases faster than the Apache server.
MongoDBMongoDB is a database program that is also classified as a NoSQL database program.In comparison to MySQL, MongoDB allows the insert, update, and delete process much easier.
Isomorphic CodeThe nature of isomorphic code allows it to run on both client (browser) and server end (NodeJS). It is possible with the JavaScript programming language.The nature of MEAN is adaptable since the flexibility of MEAN allows the transfer of code to another framework while keeping its functions intact.

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

  2. 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.

  3. Third-party Libraries

  4. 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.

  5. Performance

  6. 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.

  7. MVC Architecture

  8. 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.

  9. Data Flow

  10. 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.

  11. Security

  12. 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.

  13. Faster Development for Small Applications

  14. 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.
