With digital initiatives increasing multi-fold, the software development arena is moving towards a full-stack development trend, and one big name in these technologies is MEAN stack development. The need of the hour is fast, efficient, and dynamic websites and apps. With so many technologies floating around, it is a tough call to center down to a single option.

At such a time, the MEAN stack has been the latest jargon, and MEAN stack developers are very much in demand. Most industry segments like energy and utilities, retail and FMCG, real estate, shipping, logistics, etc. have been leveraging the potential of this powerful technology. Let us understand what this technology is all about.

What is MEAN Stack?

MEAN focuses on a free, user-friendly, and open-source JavaScript software stack to create dynamic websites and robust web applications, with its technology stack. MEAN includes MongoDB (M), ExpressJS (E), AngularJS (A) and NodeJS (N). Right from the client to the server and back, everything is dependent on JavaScript. It gives an organized way to create faster prototypes for web-based applications.

MEAN stack has been considered the ideal choice for hybrid app development with full-stack JS and it assures a quick and competent software output. Its open-source nature, utilization of a common language on both – client and server side, well-organized technology setup, and flexible development model are key reasons why developers are keen to garner expertise in this technology.

The four fundamental technologies that comprise MEAN are:

  • MongoDB – It is a popular, cross-platform database written in C++. A single document in MongoDB looks like an object in OOPS.
  • ExpressJS – It is a mature and lightweight server framework that is specially created to build single and multi-page web applications. It makes use of the Pug engine to give support for templates.
  • AngularJS – As an open-source web and mobile application framework operated by Google, AngularJS has been influential in enabling both the development as well as the testing of apps with MVC and MVVM architectures.
  • NodeJS – It is one of the world’s best performing & versatile platforms, organizations – startups, SMBs, and Fortune 500 companies seek its utilization for building a variety of web, mobile, and desktop applications, inclusive of full-stack development.

Some of the popular organizations using the MEAN stack are Google, Sisense, Netflix, Accenture, LinkedIn, Vungle, Uber, PayPal, Fiverr, Raindrop.io, UNIQLO, AngularClass, Capabilities Stack, Onkore Inc., etc.

Key Features of MEAN Stack

  • Scalable, customizable with single language development – JavaScript
  • Easy to create a full-stack application
  • Flexible to understand and easy to use
  • Huge modules library and global community support
  • Cost-effective, stores data in JSON format
  • Robust and maintainable solutions
  • The rapid development of applications and prototypes
  • Assists in avoiding irrelevant groundwork
  • Utilization of very low memory and overhead
  • Prepares isomorphic code
  • Simplification of the servery layer

No wonder why the demand for MEAN stack developers is soaring so high. Let us now understand what a MEAN stack developer does and what are the associated skills, roles, and responsibilities.


MEAN Stack Developers: Who They Are?

MEAN stack developers are JavaScript-based developers who have gained expertise in the 4 technologies that comprise the MEAN stack – MongoDB (NoSQL database that stores documents and collections in JSON format), ExpressJS (flexible server framework for creating web applications), AngularJS (frontend JS framework maintained by Google) and NodeJS (backend JS environment for server-side applications).

A MEAN stack developer is a full-stack web developer who is an expert in the above-mentioned technologies. They are also known as JavaScript full-stack web developers. Though full-stack developers deal with a superset, this technology extracts the best out of the lot, and hence MEAN stack developers are considered ideal for dynamic and flexible development.

MEAN stack developers work on the front end as well as the back end. They are application developers who work on features and modules for the front and back end, integrating APIs and forming their work structure around modern-day development approaches like DevOps and Agile.

MEAN Stack Developer Responsibilities

Here are the different MEAN stack developer responsibilities that the developers need to shoulder, to produce the best possible output:

  • Develop, test, and deploy fast and scalable web apps
  • Designing and maintenance of fully functional large relational and non-relational databases
  • Timely deployment of web apps on the cloud
  • Server management and cloud-based infrastructure
  • Establishment and integration of development tools as required
  • Identification of application issues when deploying the apps
  • App deployment on the cloud along with solving debugging issues
  • Coding architecture for frontend and backend
  • Building interactive consumer data
  • Collaboration with the IT team, researchers, and designers to design robust apps and encourage business goals
  • Creating features in apps that have a mobile responsive design
  • Testing applications and fixing bugs, along with security and data protection features
  • Establish code architecture decisions for supporting scalability and good performance
  • Makes use of popular front-end frameworks like Bootstrap, LESS, etc and design UI components
  • Participation with developers for the creation of scalable RESTful APIs
  • Conducting code reviews of peer developers
