Mean Stack Developer: Salary, Skills, Job Interview Questions

You must have heard of front-end development, back-end development, and full-stack development already, but what is mean stack development, who is a mean stack developer, and what about the mean stack developer salary? Can you become one and earn well? There are questions like that which you will have answered in this section. So let’s shoot.

There is a world of web development out there that is ever-growing, rapidly booming. At a stance like that, there is no bargain on the amount of effort that should be put into keeping up with the current trends that are there in the domain in order to survive the utterance of competence with aplomb.

In the ever-growing field of web development, it is essential to keep in aligned terms with the latest trends that are there in the domain. While you have heard to a good extent about frontend development as well as, of course, the backend development as well as full-stack development, there’s one more branch of web development that is overlooked and that is something you have to know about. This branch is what we call the MEAN Stack Development.

What is Mean Stack Development?

mean stack development
MEAN stack is the name of a branch of full-stack development that brings the combination of four technologies– MongoDB, Angular.js, Express.js, and Node.js with JavaScript in the role of its foundation. So how is mean stack development different from full-stack development?

While digital practices are increasing manifolds, the software development world is gradually moving into the full-stack development trend, and from that is where we get introduced to one of these technologies called MEAN stack development. The tech demands of today are steadfast, and dynamic along with being quite an efficient nature when it comes to the development of websites and apps. Now that there are bucketloads of different technologies roaming around, it is challenging to boil down to one option.

In such a time, the mean stack development has turned out to be the favorite of many developers, given that the mean stack developers are being immensely sought after in today’s development galore.

Majorly, the industry segments such as retail and FMCG, energy and utilities, shipping, and logistics, and real estate, etc. have been taking advantage of the potential of this sturdy technology. Let us now understand what this is all about and how it works.

What Is MEAN Stack?

MEAN is focused on a free, and open-source user-friendly JavaScript software stack that is there to create dynamic websites as well as power-packed web applications, using its technology stack. MEAN comprises M for MongoDB, E for ExpressJS, A for AngularJS, and N for NodeJS. From the server and back to the client, everything here depends on JavaScript. It comes up with an organized mechanism that helps create quicker prototypes for web-based apps.

MEAN stack has always been treated as the ideal option when it comes to the development of hybrid apps with full-stack JS and it ensures a fast and competent software output. It has an open-source nature, and its incorporation of a common language on both the client as well server-side along with well-maintained technology setup and flexible model of development are the reasons why developers are interested to hone expertise in this field.

There are fundamental technologies that constitute MEAN and that are as follows-

  • MongoDBMangoDB is a popular cross-platform database that is written in C++. A single document in it appears to be an object in OOPS.
  • ExpressJS– This fundamental of MEAN is a mature and easy-weighted server framework that is devised in order to create single and multi-page web apps. It takes hand from the Pug engine in order to give support for templates.
  • AngularJS– AngularJS, an open-source web as well as a mobile application framework that is operated by Google, has been pivotal in allowing both the development and the testing of applications with MVC and MVVM workings.
  • NodeJS– It is one of the best performing platforms out there with versatile functionality. From organizations to startups, Fortune 500 companies are willing to utilize it for building a range of web, mobile, as well desktop applications, with the inclusiveness of full-stack development.

Who is a MEAN Stack Developer?

MEAN stack developers refer to the JavaScript-based developers who carry incredible expertise in the 4 technologies that constitute the MEAN stack namely MongoDB (NoSQL database that helps store the documents as well as collections in JSON format), ExpressJS (flexible server framework that creates web applications), AngularJS (frontend JavaScript framework that is managed by Google) and NodeJS (backend JS environment for the part of server-side applications).

A MEAN stack developer is the one referring to the full stack web developer who is good in the technologies that are mentioned above. They are called JavaScript full-stack web developers. However, a full-stack developer looks after the superset and this technology emanates the best out of the lane. Thus, MEAN stack developers are known to be the ideal option for dynamic and flexible development.

MEAN stack developers work on and manage both the frontend and the backend. They are the app developers whose job is to work on features as well as modules for both frontend and backend, integration of APIs, and also, forming a work structure in the light of the modern-day development practices such as DevOps and Agile.
