Why is Mern Stack Popular for Web Application Development?

5 min read

Demands placed on modern Web apps are higher than ever. Today’s applications are expected to perform in a variety of complex scenarios with a mix of sophisticated user interfaces generated on the client using technology stack and efficient communication over smooth web APIs, all while being available 24/7 around the world.

The set of programming languages, frameworks, libraries, and tools used to create a web application is referred to as a “Stack” in the context of web development.. It typically consists of two main components: the client-side (frontend) stack and the server-side (backend) stack , named as MERN and MEAN stack, and the most popular stack amongst them is MERN Stack. T

To maintain the better flow of maintaining and creating a feasible mern stack development, the client also needs to hire mern stack developers with best skills.

You can create an entire application using a collection of technologies known as a full development stack. Typically, this will include the front-end and back-end tools you can use, along with the programming languages, frameworks, database, and APIs required to connect the two.

What is Mern Stack?


  1. MongoDB — document database
  2. Express(.js) — Node.js web framework
  3. React(.js) — a client-side front end JavaScript library
  4. Node(.js) — the premier JavaScript backend framework

The MERN stack’s popularity stems from its flexibility, as it enables developers to leverage JavaScript skills across the entire application stack, thereby streamlining development and promoting code reuse. Additionally, the vibrant community around these technologies provides extensive documentation, tutorials, and libraries, facilitating the development process and providing support to developers.

Let’s dig into the working of these technologies on how to they work in the web development process:

  • MongoDB: It is a scalable, document-oriented, cross-platform NosSQL database. With its adaptable platform, users may take tables, schemes and much more. Once MongoDB is installed, it comes along with Mongo Shell, which is a JavaScript interface that performs the querying, updating, and deleting of records.
  • Express JS: This is layered on top of NodeJS. To make creating code easier, this modular framework also enables middleware and encourages code reuse. It is especially made to carry out straightforward applications.
  • React.JS: It is a front-end library used for creating user interfaces. It is quick in handling rapidly changing data, simplifying the development of single-page and mobile applications. It also enables them to edit and refresh the page without reloading it.They can also edit and refresh the page without having to reload it thanks to this.
  • Node.JS: It is a JavaScript run-time environment backend framework that allows users to run the code on the server. It supports Node Pack Manager (npm), which is a combination of thousands of public and private node modules that are free to download.

Why is the Mern stack is Popular for Web Application Development ?

Due to its simplicity, usability, and adaptability, MERN stack is a fantastic option for companies. Its extensive feature set makes it the ideal choice for startups.

1. Quickly evolving

For companies to be able to launch their products quickly, rapid development is crucial. The MERN stack’s usage of JavaScript for both the front end and the back end enables developers to create apps more quickly. JavaScript is a very flexible language that makes switching between various frameworks and libraries simple.

The NodeJS foundation of the MERN stack enables developers to utilize a single language for both the front end and the back end, speeding up development.

2. Flexibility

There are many different libraries and utilities available with the MERN stack. It offers a selection of libraries and frameworks from which developers can choose when creating front end and back end applications. This makes choosing the appropriate tech stack for your application simpler. for your application simpler.

3. Enhancing the User Experience

Any application’s success depends on the quality of the user experience. ReactJS-based interfaces that are extremely interactive and responsive can be made by developers utilizing the MERN stack. The MERN stack uses ReactJS, a well-liked JavaScript library that provides users with a quick and fluid user experience.

This makes it possible for developers to make reused components. It also guarantees a consistent user experience across the entire program, saving time and effort.

4. Free tech stack

Developers are free to utilize the MERN stack because it is open-source. Startups in particular benefit from this feature because they frequently have limited resources and need affordable solutions. Startups can concentrate their attention on other areas by lowering the cost of developing the MERN stack thanks to open-source technologies.

Benefits of Mern Stack

1. Open Source Software

One of the key benefits of MERN stack development is its capacity to support open-source software. It expedites the development process and enables MERN stack developers to build interactive, engaging websites. This makes it simple for developers to make adjustments to their work.

2. Development of the Full Stack is Doable

The four frameworks listed above are combined into the MERN stack. With the help of the MERN stack technology, developers may build front ends, back ends, and databases utilizing each framework, each of which has its own merits.

3.The best possible experience

MERN stack lets developers create safe apps while also accelerating the development process. It can be really helpful, particularly if you’re developing an application for a sector with stringent security requirements, like the finance sector. It is a tool that speeds up development while giving users a secure and welcoming environment.


For creating web pages that come under the premium category, MERN stack is employed. It is made up of the same four technologies as the MERN stack: MongoDB, Express.js, React, and Node.js. It uses libraries, databases, and frameworks to create online web apps.

Modern web developers enjoy leveraging the MERN stack to create rich, user-friendly, and complicated apps if they have sufficient JavaScript skills. So, it simply concludes that a very seamless development process is ensured by the MERN stack.
