Why Choose MEAN Stack for Your Next Web App Project

Today’s modern websites and web apps are designed and developed keeping in mind the needs of the end users. And for this, a combination of front-end and back-end technologies work in tandem with each other.

Technology stacks like MEAN, MERN, LAMP, WAMP, .NET, etc. have already captured the web development landscape; and among these, the MEAN stack is the most popular.

This article sheds light into the various facets of MEAN stack and discusses why businesses can choose it for web app development.

Architecture of the MEAN Stack

The MEAN stack consists of four main JavaScript technologies – MongoDB, Express.js, AngularJS and Node.js.

M MongoDB 

A free and open-source NoSQL (non-relational) database, MongoDB stores and retrieves data for the application. It follows a document model (object-oriented format), where data is in the form of JSON-based documents and not as fixed rows or columns. 

This makes MongoDB a highly scalable and flexible database which can handle bulky volumes of data with ease. 

E Express.js

A Node.js web app framework, Express.js serves as the back-end unit of the MEAN stack. It runs on the Node.js server and supervises all the requests and responses between front-end and the database. 

Express is fast and minimalistic in nature; most of its features are in the form of plugins. Thus, the app does not get cluttered while Express handles processes.

A AngularJS 

Google’s AngularJS serves as the front-end of the stack wherein, client requests are received and processed and sent to the back-end. The reverse process; ie, receiving responses from the back-end and finally, displaying them as results, is also handled by AngularJS. 

Being a popular web framework with an MVC architecture, AngularJS provides excellent user experience with fine-quality UIs.

N Node.js

The main backbone of the MEAN stack is the Node.js runtime environment that concurrently handles multiple requests owing to its non-blocking, event-driven and single-thread architecture. In the stack, Node.js serves as an in-built web server for easy deployment of the app to the cloud.

The main highlight of Node.js is its scalability and superior performance. It can smoothly manage real-time app usage spikes without any dip in performance levels.

The Advantages that MEAN Stack Offers

If you are planning to build a website or web app from scratch, then MEAN stack is a fine option. It is flexible for both developers and businesses; the benefits are really great.

It’s a Single Language Tech Stack

MEAN stack can be dubbed as a ‘4-in-1 JavaScript package’! The presence of end-to-end JavaScript components, including MongoDB database, makes app development much easier. MEAN stack also allows isomorphic coding, i.e; codes written in one particular framework can be transferred and reused in another framework.

It’s Super Fast

Code reusability and the availability of a large number of additional libraries and frameworks within the stack, especially in npm (Node Package Manager), expedites web app development and reduces the time-to-market. This makes MEAN stack most suitable for startups; within a short span of time they can build MVPs (like dynamic single-page applications).

It’s Developer Friendly

A single team of MEAN stack developers can collaborate with each other as JavaScript is the common programming language in the workflows. Developers can easily switch tasks between the front-end and the back-end. Also, with code sharing across the application, developers don’t have to reinvent the wheel, thus increasing their productivity.

It’s Cost-Effective

Unlike other tech stacks like LAMP, clients don’t have to hire many developers specialized in different technologies, for MEAN stack. A single, or maybe, a few JavaScript developers are only required. This helps to reduce the overall cost of app development. Moreover, MEAN stack is free and open source. Hence, charges like licensing fees are not there.


The MEAN stack can be employed to build eCommerce apps, social media apps, news aggregation websites, workflow management tools, to name a few. So, to leverage the benefits of MEAN stack and build a robust app that will thrill your users, just hire the best full stack app development company.
