Mean Vs Mern

Choosing the right stack for projects is important for developers. This choice might affect the flexibility, expansion, and quality of your project. MEAN and MERN are the two most used stacks for developing software. They are used for full-stack development. MERN uses React js and MEAN uses Angular js to develop web applications other things remain the same.

In this Mern Stack Tutorial, we will explore more about Mean Stack and Mern Stack which will include mern stack developer full form, mean stack developer full form, and difference between mean stack and mern stack.

What is MEAN Stack?

  • The MEAN stands for MongoDB, Express.js, Angular, and Node.js.
  • Due to MEAN Stack, developers are able to develop scalable, fast web applications.
  • It can build web apps that function seamlessly on the client and server sides.
  • In the web-based VPS Management Panel, MEAN VPS is used for administrative purposes.

MEAN Stack Components

MEAN Stack includes the following four main components:

  • MongoDB: It is a NoSQL document database for storing data in JSON format.
  • Express.js: It is a back-end web application framework for building APIs and web applications.
  • Angular: Angular is a front-end web application framework for building dynamic, single-page applications.
  • Node.js: It is a powerful framework for JavaScript, providing both versatility in development and robust security features.

Pros & Cons Of Using MEAN

Let's see the advantages and disadvantages of Mean Stack



Mean has a complete JavaScript stack which ensures more accessible learning and flexibilityThe Mean stack-costly if it comes to simple websites or small-scale software
It has high scalability and real-time web functionalityIt Requires high skilled team because of its complex and time-consuming setup
Its MongoDB database manages large amounts of data.The Mean stack has NoSQL database. And it might not be suitable for all apps
Using Mean stack you can develop both front-end and back-end componentsIt has low performance issues.

Real-world Examples of Mean Stack

  • Airbnb
  • Uber
  • LinkedIn
  • Netflix
  • Facebook

What is MERN Stack?

  • The MERN stack allows developers to design a wide range of features.
  • Also, It provides a comprehensive solution approach.
  • The Mern stack will become popular in the coming years as developers use this technology to create engaging websites merely.

MERN Stack Components

The Mern Stack includes four important technologies:

  1. MongoDB
  2. Express
  3. React
  4. Node

1. MongoDB

MongoDB stores data as JSON-like documents. Mongoose ORM (Object-Relational Mapping). It allows easy integration with Node.js.

Get In-depth Knowledge of MongoDB with the following self-paced course.

2. ExpressJS

Express is a lightweight framework that enables web application development. This allows us to handle only HTTP requests and responses.

3. ReactJS

React is a library written in Javascript for building the front end of applications. In ReactJs programmers can build reusable elements and Manage application state efficiently. Also, React supports server-side rendering, which allows developers to improve performance and increase the SEO of their applications.

4. NodeJS

Node.js is a JavaScript runtime environment that provides developers with a platform to run code written in JavaScript outside of the browser. Additionally, Node.js builds server-side applications on top of his MERN stack with many built-in modules for file I/O, networking, and security.

Pros & Cons Of Using MERN 

Let's see the advantages and disadvantages of Mern Stack

Mern also has a complete JavaScript stack which ensures more accessible learning and flexibility It has limited tooling and libraries
It has high scalability and real-time web functionality It has high memory usage
Mern stack is easy to learn and useSometimes Difficult learning curve for beginners
It has a rapid development timeIt requires advanced knowledge of JavaScript

Real-world Examples Of MERN Stack

  • LinkedIn
  • PayPal
  • Intel
  • Accenture

MEAN Vs MERN: Difference in a nutshell

MEAN Vs MERN: Difference in a nutshell

Which One To Choose: MEAN or  MERN 

If it comes to choosing between Mean Stack or Mern Stack Developers will be confused. Let’s talk about how to choose between Mern Stack or Mean Stack depending on factors.

1. Cost

  • We should consider the cost of development before choosing a tech stack.
  • If we analyze, MEAN stack, which uses Angular, is slightly more expensive than MERN, which uses React.

2. Project Requirements

  • The requirements of the project determine which stack is most appropriate for the task.
  • MERN is a great fit if you are creating real-time software as it uses Socket.io that facilitates communication in real-time.
  • However, MEAN might be a better option if you’re developing a more conventional web application.

3. Scalability & Flexibility

  • Scalability and flexibility are important elements to consider by enterprises especially when developing apps that require to grow.
  • Both MERN and MEAN stacks are scalable, but MERN is more flexible as compared to mean.
  • MERN stack uses a Node.js framework which increases more flexibility.
  • It can also handle a variety of tasks, such as server-side and client-side rendering.

4. Developer Expertise

  • Businesses need to take into consideration the experience of the experts working on the project.
  • In case your developers possess knowledge of Angular, MEAN could be a more suitable option.

5. New Practices

  • Lastly, businesses should consider new practices when selecting a tech stack.
  • The MERN stack is a relatively new technology that has grown more recently.
  • The MEAN stack has a stable ecosystem and is more established.

So in this article, we have learned the difference between mean stack and mern stack. I hope you enjoyed learning these concepts while programming with JavaScript.
