August 07, 2019 By Angelina Eillott Category: MEAN Stack

In today’s dynamic world, churning out rapid application prototypes with super-flexible design which adapts to volatile specifications is the key business requirement. This necessitates a software stack which gives the required freedom and power to the developer to assume a flexible, locally owned schema, in-built support for end to end testability and harness the ever growing open source repository of re-usable plugins for speedy iterations.

The one technology that has been promising fulfilment of all these requirements, in the best manner possible is, MEAN stack development – a contemporary and budding trend for JavaScript development.

MEAN (MongoDB, Express, Angular & Node.js) is an open source JavaScript bundle for web-applications consisting of following components which can very well be used independently:

  • MongoDB – Mongo DB is an open source database follow object oriented programming language because it is written on C++. It provides high availability and scalability.

  • Express.js – It’s a simple web application framework that works as a server-side JavaScript framework running on top of Node.js

  • Angular – Angular is a web supplication based open source framework used to create mobile and web applications. Its productivity, testability, performance and speed is much better than other web based frameworks.

  • Node.js – Open source server-side JavaScript runtime environment that run JavaScript code on different platforms like windows, Unix, Linux, Mac OS, and many more.

Advantages of using MEAN Stack

Large pool of JavaScript developers:

Java developers have always been at a premium for enterprise development. With the Web revolution, there was a large untapped pool of JavaScript developers out there to be leveraged for full-fledged Enterprise application development.

Young developers love the inherent freedom and flexibility of JavaScript (no compilation, no type declarations and no restrictive Object oriented programming principles to master before jumping in to write any code!) which meant a lower barrier to entry for new developers.

Declarative UX and testability:

Over the last few years, Angular emerged as a clear winner among the plethora of confusing JavaScript UI libraries with its promise of code-less browser-independence, natural blending with HTML to adapt it for application development, two-way binding and finally, a clean separation of presentation from UI logic.

To tame the uber-flexible dynamic language and bring predictability to the output, open source BDD-style unit testing tools like Jasmine, task runners like Karma came handy.

Cloud-hosted continuous-integration services like CircleCI make life easier.

Easier debugging and code-reuse:

When you have a single language to work with across layers, it becomes easier to trace the execution thread, watch how the data gets manipulated and debug the flow with a consistent set of free open-source tools.

Libraries developed once can be seamlessly reused for front-end as well as back-end resulting in significant boost to productivity. The thriving npm.js repository for every imaginable task in hand is the proof of the pudding.


Node.js’s underlying V8 JavaScript engine by Google is known to utilize server resources efficiently due to its non-conventional single-threaded execution model, which is a notable departure from the classic Java (and C#.NET) multi-threaded way of handling concurrent execution, synchronization, locks etc.

Node.js provides testable concurrency without the headaches and uncertainty of multi-threading/cron jobs. First, the I/O based event loop architecture and C++ core modules deal with thousands of requests with ultra-frugal utilization of CPU and memory unlike a JVM.

In addition to that, the dynamic load can be handled by leveraging the Cloud’s natural horizontal elastic scaling capability by launching additional instances on the fly. Finally, MongoDB’s cloud-ready replication and its features boost the performance with great availability.
