Beyond MEAN: Why MERN is the New King of Full-Stack Development

Discover why MERN outshines MEAN in full-stack development. Unleash the power of MERN stack now!


Web development has been evolving continuously with the emergence of new frameworks that offer unique advantages and capabilities. Among the many frameworks that have taken the web development landscape by storm, the MERN stack has become increasingly popular in recent years. MERN is an acronym for four powerful technologies MongoDB, Express.js, React, and Node.js that work together to offer a complete solution for full-stack web development. 

In this article, we will look at why MERN is taking over web development frameworks and why you should consider using it for your next project.

Stacks: MERN vs. MEAN

MERN and MEAN are two popular stacks used for developing full-stack web applications. The primary difference between the two is that MEAN uses Angular for front-end development, whereas MERN employs React. While both stacks have a sizable developer following, MERN has gained popularity in recent years due to React’s flexibility, ease of use, and the vast library of open-source tools and components available in the React ecosystem. 

Moreover, MERN is considered a lighter choice than MEAN since Angular has a steeper learning curve and might be more difficult to work with. Ultimately, the choice between MERN and MEAN stack is determined by the project’s specific requirements and the development team’s preferences.  Additionally, the decision between the MERN and MEAN stacks should also include considering factors such as scalability, performance, and community support.

Stack Battle: MERN vs. MEAN

MySQL vs. MongoDB Databases 

The MEAN stack, in contrast to the MERN stack, uses MySQL as its database instead of MongoDB. MongoDB is a NoSQL database that stores information in documents that look like JSON and use flexible schemas. This makes it an attractive choice for programs that require a versatile and extensible database structure. MySQL, on the other hand, is just a regular SQL database, and it’s utilized by a wide variety of web-based programs.

React vs. Angular

The MERN stack employs the front-end framework React, while the MEAN stack favors the framework Angular. Both frameworks enjoy widespread support, although React tends to garner more praise for its versatility and user-friendliness. React’s virtual DOM, which allows for faster component updates and rendering, is another well-known feature.

JavaScript vs. TypeScript as a language

The MEAN stack is built with TypeScript, a superset of JavaScript that includes static typing and other language capabilities. But, standard JavaScript is used in the MERN stack. While TypeScript has several advantages—including increased developer productivity and code quality—it also adds complexity and may need some learning on the part of developers who aren’t already familiar with it.

Node.js as a server

Both the MEAN and MERN stacks rely on Node.js as their server-side platform. The MERN stack may need further server-side configuration and optimization to support server-side rendering, however, because React is used.

Discover Why MERN Stack Is the Next King of Full-Stack Development

Now we’ll take a close look at the MERN stack to understand why it’s become the new king of full-stack development.

  • One of the MERN stack’s biggest benefits is that it is entirely written in JavaScript, which makes it straightforward for programmers to design scalable and high-performance applications. This enables collaboration between front-end and back-end developers without requiring them to master different programming languages.
