Introduction to MEAN Stack: What it is and How it Works


The MEAN stack is a web-developing application based on the JavaScript framework. MEAN stack is a fusion of four key technologies that develop the layers of the stack.

Introduction to MEAN (MERN-TEST) Stack

The MEAN stack is a web-developing application based on the JavaScript framework. MEAN stack is a fusion of four key technologies that develop the layers of the stack. These include MongoDB, Express, Angular, and Node and MEAN stack is an abbreviated form of these constituents.

MongoDB: Document database

Express (.js): Node.js web framework

Angular (.js): A client-side JavaScript framework

Node (.js): The premium JavaScript web server

MEAN stack is of great value because of its flexibility and the quality that it just employs JavaScript. As it is all written in JavaScript, a professional MEAN stack developer should be an expert in the language

What is MEAN Stack?

MEAN Stack is one of the most widely used technology stacks. These technologies are based on the JavaScript language. This stack is for rapid development and deployment of the Web Application. Angular is for Frontend Development while Node.js, MongoDB, and Express are for Backend Development. Free online courses are available for learning MEAN Stack Technology as it's been a decade that MEAN stack is in great demand for both websites and web applications. 

History of MEAN Stack

The root of the MEAN stack began in 2013 when Valeri Karpov coined the acronym MEAN in his blog post and logo concept. The initial source was created by Austin Anderson for the authentic LinkedIn group. He assembles the first letter of each constituent of the MEAN acronym. That's how the MEAN stack came across the board. MEAN stack is the blockbuster when it comes to web-centric application development. It is very easy to manage both front-end and back-end development as all its members follow the same JavaScript language. So, it requires a shorter span for the project. Over the course of time, the demand for the MEAN stack has triggered plenty of derivations. It serves as an irresistible force globally. It endures a famous choice of tech stack for the development of web-driven applications. Features of MEAN Stack:

MEAN stack development offers multiple key features that make it an appealing tool for building web applications. Depending upon the benefits of the incredible four technologies of the MEAN stack, there are certain key features of it. These features make it the best option for building web applications. These are briefly explained here:

JS-based Web Development

The foremost feature of MEAN stack development is that it is completely JavaScript-based. It would be feasible for developers to maintain and develop applications effortlessly. JavaScript is a well-known programming language and has an ample developer community, which makes it possible to find support and resources for development.


All technologies involved in the MEAN stack are programmed to be scalable, making it effortless to build applications that can control large amounts of data and traffic. MongoDB is designed to drive large amounts of data and scale horizontally, while Node.js can simultaneously control various requests.


The technologies used in the MEAN stack are open-source, so they are convenient to use, modify, and distribute. There are no licensing fees or costs involved in using this technology stack which renders it an affordable choice for developers and businesses.


The MEAN Stack Technology is developed to be flexible, letting developers use the tools and technology that meet their project requirements. For instance, Angular.js is used by developers to create responsive and versatile user interfaces, while MongoDB can be used to save some unstructured data. The flexibility of this application enables us to create custom applications that fulfill the required needs of a project or business. 

Support of Powerful Angular Framework

HTML and CSS shape the interface quite simply and supportive while applying Angular as a web application framework. This addition in MEAN Stack makes MEAN Stack web development user-friendly and helpful to build efficient web apps.

Rapid Development

MEAN Stack development is famous for its rapid development process. It offers a range of tools and features that makes it convenient and efficient to build applications, including pre-built templates, built-in modules and libraries, and easy integration with third-party modules. MEAN Stack development saves your business time and expenses, making it the best option for startups and small businesses.

Benefits of using MEAN Stack

Overall Cost-effective

One of the prime benefits of MEAN Stack web development is that it is an open-source technology stack. It means these programs are offered without any licensing fees or charges that facilitate small businesses. The MEAN Stack is the best option for limited-budget projects.

Hiring MEAN Stack Developer is Affordable

As we have already discussed, JavaScript is the sole programming language essential to do full-stack development using the power of MEAN stack technologies. This eliminates the need to search for and assign web developers specialists in other specific languages. Thus it minimizes the need of hiring considerable resources to develop a web app. 

High Web App Performance

MEAN Stack is a high performer App, thanks to the combo of four key technologies- MongoDB, Express.js, Angular.js, and Node.js. These technologies are developed to be efficient and fast, allowing businesses to develop applications that are vigilant and responsive, even under traffic loads.

Easy Maintenance

Another benefit of MEAN Stack development is that it is simple and easy to maintain. As all the technologies in the stack use JavaScript, developers only have to learn a single programming language to operate the entire stack. Ultimately this makes it easier to run applications. In addition, the modular architecture makes it handy to add new features or update running ones without affecting the entire system.

How does MEAN Stack work?

This open-source stack is developed to build cloud-hosted apps. These apps are adaptable, scalable, and dynamic, making them perfect for hosting services. The MEAN Stack comes with its web server so that it can be installed conveniently. The MEAN application is introduced into the world tailored to take full benefit from the cloud’s efficiency gains and speed boosts. The MEAN Stack works as a combination of four technologies so let's explore them layer by layer:

M: MongoDB is a NoSQL document database. It stores data in JSON-esque documents, which puts on flexibility and accessibility. So, the data can be conveniently shared from the client to the server.

E: Express (.js) is a flexible Node.js framework for developing web applications. It is used to build single and multi-page applications along with hybrid applications.

A: Angular is a structural JavaScript framework for building dynamic web applications. It is used to create web applications fastly and efficiently.

N: Node(.js) is a JavaScript web server used for creating network applications.

Who uses MEAN Stack?

MEAN applications can be used in multiple ways with a compatible write-once approach. It is specifically suitable for real-time applications and for the following cases:

  • Todo and calendar applications
