All About MEAN Stack That You Must Know

The phrase “stack” comes from the software development world and refers to the tools and languages used to build sophisticated online and mobile apps. Software companies now combine several technologies to facilitate quicker and more dynamic web development.

What Is MS?

MEAN is an abbreviation for the individual components MongoDB, ExpressJS, AngularJS, and NodeJS. These innovations in technology occurred at various times. However, these technologies are now bundled together under the MEAN stack, and the rationale for this is not hard to deduce. JavaScript is the glue that holds things together, while it is an open-source, server-side, and client-side scripting language for building dynamic online applications.

Linguistic Isolation and Growth

The fundamental advantage of the framework is that a single language is used for both the client and the server sides of the development process. Having everything written in JavaScript makes web development much more organized.

Let’s get a grasp of this using a different stack, LAMP. You use PHP to write the server-side code, SQL to query the MySQL database, and JavaScript for the client-side UI. So, what would happen if you were forced to learn only one language? Node.js is a system that allows it to run JavaScript in a server environment. On the front end, AngularJS also use JavaScript. JavaScript is, thus, pervasive.


Storage and display capabilities are the most crucial aspects of every program. If you need a database that can handle large amounts of data, MongoDB is a fantastic option. And when compared to other databases, updating all data in MongoDB is easier. Meanwhile, if you’re familiar with object-oriented programming, you’ll find many parallels between the documents in MongoDB and the objects in that language.

Use Express JS

Express is a back-end framework that offers an easier-to-use interface for making requests, creating endpoints, managing cookies, and other similar tasks. Some of Express’s most prominent characteristics are as follows:

  • A mechanism for configuring middleware to handle incoming HTTP requests.
  • Sets up a routing table to handle requests differently depending on their URL and HTTP method.
  • Allows supplying parameters to templates for dynamic HTML page rendering.

Angular JS

A front-end JavaScript development framework, Angular.js is used to create dynamic, interactive, and feature-rich single-page apps. It is a tidy approach to integrating AJAX-driven rich components and functionality onto a web application’s client side, facilitating developers’ collaboration. The ability to build single-page apps using AngularJS is a cutting-edge feature that would save customers time and frustration throughout the checkout process by eliminating the need to refresh pages repeatedly.

Node JS

Node.js was developed on top of the JavaScript V8 Engine found in Google Chrome, making it a compelling framework or platform. It is used to build websites requiring a lot of input and output, such as video-streaming sites and single-page apps.

NodeJS is a suitable option for Real-Time apps since it is open-source and works on several platforms, and is written in JavaScript. Additionally, NodeJS is platform-agnostic, meaning that it can be easily created on any OS and operates at the same pace regardless of whether you’re using Windows, OS X, or Linux.

Use of the JavaScript Object Notation (JSON) Universally

NodeJS, AngularJS, and even MongoDB all save data in JSON. It works wonderfully for more extensive endeavors. Therefore, JSON is used all around the software, and there is no requirement to restructure the information.


There is no need for a business to bring in many experts to work on the development of a single MEAN stack application. A small team of highly skilled JavaScript developers may manage the entire system. And since its components are open source and can be installed and operated on any server, the application’s deployment costs are reduced.
