MEAN stacks

What is the difference between MERN and MEAN stacks?

Web application development is constantly evolving and improving. In an increasingly demanding market, developers have to master various technologies that can be used both in the front-end and in the back-end, or, what is the same, in the part that interacts with users or clients.


This is how technology stacks or solution stacks arise, groups of software tools that can work separately or together to create a particular product. The most popular are MERN and MEAN Stack. Each of the parts that make up the stack performs a specific function, from data collection to design.

A Full Stack developer must have the knowledge to work in both the front-end and back-end. The technology stack brings together all the programming languages, the operating system itself, frameworks, and tools that a developer needs to work on the content of an application. There are several alternatives, the choice of one or the other will depend on the type of application and the needs that will arise throughout the process. It may even be necessary to use different technology stacks.

To select a stack, you need to know the features of the project in which you are going to work. Once they are clear, programmers decide which technology and programming language to use. Usually, when a central coding language is chosen, other tools are added. The knowledge and previous experience of the people who make up the work team will also determine the choice, and the same goes for scalability.

If you need help with such developments, then you should contact the specialists at who will help you implement any project according to your preferences.


It is critical to implement an agile methodology where user interaction prevails throughout the process and there is significant responsiveness to changes and unforeseen events.

Grouping all those elements that you are going to work with has the great advantage that both loading and applying at the same time become easier. The two most popular stacks are:

MERN vs. MEDIUM stack

MEDIUM stack

Responds to the initials of its components:



A database that allows you to store application information as JSON files.

Express or Express.js

The framework or internal base structure on which the project will be developed.


A front-end framework that runs JavaScript code in the browser.


A real-time runtime that provides all the tools needed to run a program written in JavaScript.

MEAN Stack is a JavaScript-based toolkit. It is used to develop both websites and applications. The use of a single language throughout the package allows for code reuse. It is an open-source technology that is particularly suitable for working in the cloud. It also includes its server.

MERN stack

It is very similar to MEAN, the main difference is that it does not use AngularJS, but React:

  • MongoDB
  • ExpressJS
  • ReactJS

A library that provides the ability to create high-quality single-page web applications, speeds up work, and simplifies changes.

MERN is a solid stack when it comes to developing complex and dynamic applications. Offers flexibility and scalability.

Both stacks guarantee to work with MVC (Model View Controller) architecture, which makes everything smoother. The learning curve is acceptable and they cover the entire development process: it is important to choose the one that best suits the requirements of the project to ensure its success.
