MEAN vs MERN: A 5-Point Comparison

In this section, you will find several points relevant to the MEAN vs MERN comparison. Understand each parameter as they help define your choice of a suitable tech stack.

Mean vs Mern Stack: The Learning Curve

Mean vs Mern Stack: The Learning Curve

Both the prominent stacks have three common components:

  • MongoDB
  • Express.js
  • Node.js

So, developers require the same level of time, resources, and effort to study and implement these technologies. However, the mean stack has Angular, while the mern stack has React as its client-side framework.

Angular has a steep learning curve. On the other hand, React.js is simple to use and has a comparatively flexible configuration.

In terms of the MEAN vs MERN learning curve, the latter is a better choice.

Mean Stack vs Mern Stack: Third-party Support

Mean Stack vs Mern Stack: Third-party Support

If you want to develop apps, websites, or portals with several third-party integrations, choosing the mean stack can be an excellent decision.

The developer community of the mean stack is large and diverse. So, query resolution can be prompt and third-party support is robust.

On the other hand, the community of mern stack is still growing. The tools and plugins are limited in comparison. There is also a need for additional configuration when you use the React framework.

All in all, in this MEAN vs MERN comparison point, the former stands out to be a good choice.

Mean vs Mern Stack: The Architecture

Mean vs Mern Stack: The Architecture

The mean stack has a Model-View-Controller architecture. This setup segregates an application into three sections:

  • Data
  • User interface
  • Logic

This separation enables ease in modifying the codebase. Also, dedicated developers can maintain an application effectively.

On the contrary, the mern stack has a three-tier architecture. It improves scalability and includes separate functionality for each layer as follows:

  • Client-side –> View
  • Server-side –> Model and controller

Notably, the changes to a single layer do not have any impact on the other two. However, this feature is possible if the interface between the layers is consistent.

On the MEAN vs MERN architecture front, the comparison ends in a tie. The end utility and project requirements influence the choice of the tech stack.
