MEAN & MERN Stack development in Bangalore - GSA Techworld

Web application development involves creating an application that can run on any device with a web browser. The popularity of web applications has grown tremendously in recent years, and with it, the need for robust web application stacks. MEAN and MERN are the most popular stacks for web application development. In this article, we’ll explore both stacks in detail and try to determine which one is best suited for your needs.

MEAN Stack for Web Application Development

MEAN Stack development in Bangalore - GSA Techworld

MEAN is an acronym that stands for MongoDB, Express.js, AngularJS, and Node.js. It is a free and open-source stack that allows developers to create web applications using JavaScript as the primary programming language. Let’s take a closer look at each component of the MEAN stack:

  1. MongoDB – MongoDB is a popular NoSQL database that is used to store and retrieve data in MEAN stack applications. It is a document-oriented database that can handle large amounts of unstructured data.
  2. Express.js –  Express.js is a lightweight framework that is used to build web applications in Node.js. It provides a simple and efficient way to handle HTTP requests and responses.
  3. Angular.js – AngularJS is a popular front-end framework that is used to build dynamic web applications. It provides a robust set of features that allow developers to create complex user interfaces
  4. Node.js – Node.js is a server-side JavaScript runtime that is used to run JavaScript code on the server. It is built on top of the V8 JavaScript engine and provides a scalable and efficient way to build web applications.

Why do developers choose MEAN Stack for web application development?

Flexibility and scalability: 

MEAN stack offers high flexibility and scalability for web development. It allows developers to switch between the front end and the back end easily. MEAN is an open-source platform, meaning developers can easily leverage the codebase and integrate new features and functionalities. It also supports horizontal scaling, which means you can add more servers to handle increased traffic. Read 9 Step Process of Website Development. 

Speed of web app development: 

MEAN stack uses JavaScript for both frontend and backend development, which significantly speeds up the development process. Since JavaScript is a popular language, a vast community of developers can assist with any website development challenges.

High performance: 

MEAN stack provides high performance due to its use of Node.js, which is a server-side JavaScript execution environment. Node.js allows developers to build high-performance web applications that can handle a large number of requests without impacting performance.


Since the MEAN stack uses open-source technologies, it reduces the overall cost of web application development. The use of open-source technology also reduces licensing costs, which makes it a more affordable option for small to medium-sized businesses.

Real-time applications: 

MEAN stack is suitable for building real-time applications, such as chat apps and online gaming platforms. The use of Node.js allows developers to create real-time applications that can handle multiple requests simultaneously.

NoSQL database: 

MEAN stack uses MongoDB, a NoSQL database that provides a flexible and scalable data storage solution. MongoDB can handle large volumes of structured and unstructured data, making it suitable for applications that require a scalable and flexible database.

High security: 

MEAN stack uses multiple layers of security to protect against security threats. MongoDB provides a secure data storage solution, while Node.js provides a secure execution environment for JavaScript code. MEAN stack also uses Express, which provides a robust framework for building secure web applications.

Single language: 

MEAN stack uses a single language, JavaScript, for both frontend and backend development. This means that developers do not need to learn multiple languages to develop a web application, which reduces the overall complexity of the development process.

Large community: 

MEAN stack has a large community of developers who contribute to developing and maintaining the technology stack. The community provides a vast range of resources, including tutorials, forums, and documentation, which makes it easier for developers to get started with the MEAN stack.

MERN Stack for Web Application Development

MERN is an acronym that stands for MongoDB, Express.js, React, and Node.js. It is a free and open-source stack that is similar to MEAN, but with React replacing AngularJS as the front-end framework. Let’s take a closer look at each component of the MERN stack:

  1. MongoDB: Same as in the MEAN stack.
  2. Express.js: Same as in the MEAN stack.
  3. React: React is a popular front-end framework that is used to build dynamic web applications. It is known for its simplicity and efficiency.
  4. Node.js: Same as in the MEAN stack.

Why do developers choose MERN Stack for web application development?

Full-stack JavaScript MERN stack uses JavaScript as the primary programming language for both frontend and backend web app development. This means that developers can write code using a single language, making managing the entire web app development process easier. Additionally, JavaScript has a vast developer community, which means there are plenty of libraries and frameworks to choose from.

Easy to Learn

MERN stack is easy to learn and can be picked up quickly, even by developers with limited experience in web app development. The entire stack is built using JavaScript, which is a familiar language to most developers. Moreover, the stack uses simple and straightforward technologies, making it easier for developers to get started.

High Performance

MERN stack is known for its high performance. MongoDB, the database used in the stack, is a high-performance NoSQL database that is designed for scalability. Node.js, the runtime environment, is built on Chrome’s V8 JavaScript engine, which provides fast and efficient performance. React, the frontend framework, uses a virtual DOM to minimize the number of updates required to render changes, resulting in faster page load times.

Modular Architecture

MERN stack uses a modular architecture, which makes it easy to develop, test, and deploy web applications. Each technology in the stack serves a specific purpose and can be replaced with another technology if necessary. This flexibility makes it easy to customize the stack based on project requirements.

Large Community Support

MERN stack has a large community of developers who actively contribute to its development and support. The community offers a wide range of resources, including documentation, tutorials, and forums, making it easier for developers to learn and solve problems.

Rapid Development

MERN stack offers rapid development capabilities, allowing developers to build web applications quickly and efficiently. With the use of pre-built components and libraries, developers can quickly develop applications without having to write complex code from scratch.

Bottom Line

Both MEAN and MERN stacks have their own advantages and disadvantages, and the choice ultimately depends on the specific requirements of a web application project. MEAN stack is suitable for projects that require a robust and scalable database, while the MERN stack is ideal for real-time web applications that need to handle a high volume of data and user interactions.

Regardless of the choice of the stack, both MEAN and MERN have gained popularity among developers for their open-source nature, ease of development, and flexibility in terms of the choice of tools and libraries. The use of JavaScript across the entire stack also makes it easier for developers to work on both the front-end and back-end aspects of a web application.

In conclusion, the decision between MEAN and MERN stack depends on the specific requirements and objectives of a web application project. By leveraging the strengths of each stack, developers can build robust, scalable, and efficient web applications that meet the needs of their clients and users.
