MEAN Stack & Startups – Are they Made for Each Other?

Mean Stack Technology

In today’s digitally intensive web development world, every organization is keeping up with the incessantly developing IT workspace. And to remain conversant with the ever-evolving technology, developers are coming up with developer-friendly solutions for the benefit of the programmers. And one such solution formed with the amalgamation of technologies is termed as ‘Web Stack.’

Of the several available web stacks, the MEAN stack is considered as the best framework that makes perfect use of amalgamated technologies. Compared to its competitors,  MEAN seems to be winning the contest in terms of ‘popularity,’ putting together an unparalleled tonic catering to today’s software development requirements of renowned enterprises as well as startups alike!


MEANing of MEAN Stack

MEAN stack is an assortment of various technologies – MongoDB, ExpressJS, AngularJS, and Node.js, bound together by a single, dynamic programming language- JavaScript, for building a robust web application. From client to server to database, MEAN is a full stack JavaScript.

MEAN Stack Architecture

Netflix switched from Java on server-side and javascript on frontend side to node.js because they had to write everything twice for error handling, activity tracking, and debugging. As Node.js act as a common language for both server side and browser side, it brought down the startup time to under a minute from 40 minutes+.

Used and accepted by companies like Paypal, Netflix, and NASA, MEAN stack has penetrated deep into the web application development world because of the following benefits:


The event-driven architecture of Node.js in MEAN Stack allows many concurrent requests with less slowdown, making it fast compared to its competitors.

PayPal in its experiment revealed that an app built with Node.js as a platform took half the time with response time 50% faster and 33% fewer lines of code to construct than the Java app.

Based upon asynchronous programming, Node.js makes the processes such as I/O to network connections, file system, and database execute very fast. Built on Google’s V8 JIT-compiled JavaScript engine, the JavaScript code gets compiled and executed into native machine code very quickly. Moreover, creating web application rotating across the single language makes the development process swift, neat, and less cumbersome.


Isomorphic Code

As per the survey of Stack Overflow annual survey, JavaScript is the most-used programming language, used by 62.5 percent of the respondents.

Isomorphic Code

MEAN stack allows isomorphic coding – transferring the code written in one specific framework to another is made stress-free with MEAN Stack, which is the major reason for its popularity. Being a common language for both client-side and server-side, it becomes easy to understand the data flow through the components from the client to the server. This is advantageous in a startup as the coding resource can be effectively used.

JavaScript does not require software of its own, it all needs its own web browser for executing a web page or an application. Initially, a client-side web programming language, JavaScript manages all the components of MEAN stack effectively.


The capability of scaling accordingly is something that drives many developers towards choosing MEAN Stack technology. With MEAN Stack, it becomes easy to scale all the layers of the frontend, backend, and database.

The features of MongoDB like auto-sharding, replication, and high-availability makes it easy to scale without worrying about failover. However, the major loophole with MongoDB is that most solutions are not as strongly ACID-compliant (Atomic, Consistency, Isolation, Durability).


On the other hand, the single threaded asynchronous architecture of node.js enhances the scalability and performance of applications. This is the reason that from a server-side perspective, developers choose to build their software stacks on Node.js completely. And Startups aren’t the only ones that benefit from this, as it is noticeable in several established brand examples.


According to a survey held by Juniper Research, it is concluded that cyber attacks are the biggest threat to the online businesses that will lead to annual financial losses from data breaches accounting to $2.1 trillion by 2019. Hence, keeping the web application secure should be the foremost parameter while choosing the web stack.


When it comes to security, MEAN Stack is a secure and stable platform. MongoDB, a non-relational database is not prone to SQL injection as the data stored are JSON objects, manipulated by SQL strings, which opens up the way for robust database security. Being a NoSQL and document database, it becomes flexible to use in a myriad of applications. Hence, it becomes simplified, thus minimizing the usage of joins.

And when it comes to Node.js, its core contributors and Node.js itself maintain a variety of channels to address the security of the Node.js project and its users. Even in 2016, a Security Working Group was formed at Node.js Interactive in Austin, whose main aim is to define and maintain security policies and procedures for the core Node.js project and other projects maintained by the Node.js Foundation.


As per a study, about 36.9 percent of software engineers now apply AngularJS to create user interfaces and its popularity can be perceived from the following Google Trend too.


Built with a Model-View-Controller architecture, AngularJS leads to two-way data binding, thereby supporting rapid and parallel development. It implies that as the data in Model changes, the same changes can be seen in View too, thereby deleting the need for additional code to provide continual View and Model synchronization.

This process reduces the development time to three times. It is popular among startups because of its ability to smoothly make changes in the future for further enhancement.


MEAN Stack – The Right Web Stack for Your Next Project

The most vital thing to consider when sketching a roadmap to build a top-notch web application is choosing a ‘Technology Stack’ upon which a web app will be based. The right web stack will be the key to the project’s success, whereas choosing the wrong web development technologies may end up with project failure.

MEAN stack has grown as a popular choice among full stack developers over the years. The solutions offered by MEAN stack to startups come across as propitious because of its ability to connect with Javascript and the ease and flexibility offered by it, thereby, turning out to be an assured sustainable solution for Startup enterprises.
