The Key Difference: MEAN Stack vs MERN Stack

Before selecting any technology stack for building an enterprise-grade solution, one should constantly evaluate it on the below-listed basis. It will ensure a long-lasting application providing edge-to-edge services to all the stakeholders.

  • Performance
  • Security
  • Third-Party Integrations
  • Data Flow
  • Support for MVC
  • Code maintenance and Advancement
  • Mobile App Creation
  • CRUD Applications
  • Fewer Errors

Performance: MEAN Stack vs. MERN Stack

Selecting the right technology for building software achieves the primary objective of any application: fast, smooth, and accurate execution of user requests.

  • MEAN Stack utilizes the Angular Framework, which functions upon the accurate Document Object Model.
  • MERN Stack employs the React Framework, which deploys updates in the virtual DOM, enabling faster operation performance compared to Angular.

Additionally, apps created using MERN Stack are lightweight, and developers are free from defining state transitions, boosting performance.

Security: MEAN Stack and MERN Stack

Crafting a secure application structure for handling and maintaining data integrity is a top-level priority, and technologies included in the MEAN and MERN stack fulfill it. The primary difference between these stacks is the Angular and React framework, and both offer advanced incorporated security modules. In addition, these applications use MongoDB, which prevents SQL injection attacks and ensures the confidentiality of the stored data in the communication channel.

But, in scaling up the security mechanisms with external tools and APIs, the MEAN stack is more compatible.

Third-Party Integrations: MERN Stack vs MEAN Stack

To extend the traditional functionalities of applications, developers integrate external tools, APIs, plugins, libraries, virtual machines, and widgets. For enabling the encrypted data transmission using SSL, modules for supporting HTTPS should also be present in the installation package. MEAN requires third-party components to enable the same functionality that the angular framework provides with its built-in HTTPS installation and configuration functions.

Moreover, MEAN provides an effortless way to add and remove any externally sourced services, such as Cloud, without affecting other modules, just like a plug-and-play mechanism. MERN technologies require additional configurations for similar purposes.

Data Flow: MERN Stack and MEAN Stack

MEAN follows a bidirectional approach, and MERN follows a unidirectional for flowing the data within the different application components. Each stack considers a specific type of application with its contrasting data flow mechanism.

  • MERN is utilized for large-scale projects that require extensive data processing.
  • MEAN is highly regarded for small and medium software applications.

In the bidirectional flow of Angular, the user interface and model state are linked, as any modification in the UI automatically changes the state. In comparison, MERN eliminates it through unidirectional flow and offers to craft an optimized data processing channel.

Support for MVC: MEAN Stack and MERN Stack

The Model-View-Controller (MVC) architectural pattern offers several technical advantages in software development. It facilitates faster development by segregating concerns, supports test-driven development (TDD) practice, and enables developers to employ asynchronous method invocation for ease of modification. In the context of enterprise-level application development, MEAN stack, a technology stack encompassing MongoDB, Express.js, Angular, and Node.js, is commonly utilized to implement the MVC architecture.

This approach promotes a focused and modular approach to software development, allowing developers to address each layer (Model, View, and Controller) individually. It results in a more organized and efficient codebase, ultimately leading to improved software functionality and maintainability.

Code maintenance and advancement: MERN Stack and MEAN Stack

With a briskly evolving market, businesses must modernize their applications accordingly.

  • As MEAN stack-based solutions follow the MVC approach, developers can differentiate between the back-end and front-end code. As a result, any back-end code change doesn’t degrade the code written for the interface and vice-versa.
  • MERN stack developers need to resolve the complexities of third-party embedded APIs and tools before performing any advancement.

Mobile App Creation: MEAN Stack and MERN Stack

Along with websites and web apps, mobile applications are necessary for reaching out to the targeted audience. Developers can fabricate a robust mobile application with Angular and React, but it depends upon the business demands while picking out the tech stack. If your business needs a hybrid application for iOS and Android users, then MEAN is the perfect fit, as Angular offers its Ionic framework for such development.

Further, if you want to provide a native experience to the user, MERN will be the perfect fit for innovating an appealing mobile app.

CRUD Applications: MERN Stack vs. MEAN Stack

CRUD stands for Create, Read, Update, and Delete, and these apps are used to prevent casual browsing and perform database operations with ad hoc SQL statements. The development team utilizes MERN for fabricating CRUD applications due to the incorporation of ReactJS for managing dynamic modifications in data and interface. In addition, if your organization needs a single-page application, the MEAN stack is the right choice.

Fewer Errors: MEAN Stack vs MERN Stack

Typescripts are utilized while creating Angular-based software, and it is more effective in spotting bugs and errors in the early stages. Moreover, with fast refactoring and IDE support, one must go for the MEAN stack to reduce glitches and vulnerable loopholes in the business solution.
