Spread the love

MEAN stack is a JavaScript framework for full stack developers. It’s an Open-Source Full-Stack Solution For MEAN Applications. In this post, we have brought up a detailed MEAN Stack Tutorial for web developers who are willing to become full stack developers.

MEAN stack is a collection of various JavaScript-based web development technologies which includes M-MongoDB, E-ExpressJS, A-AngularJS, and N-NodeJS.

From the layman viewpoint, you can imagine that MEAN is a full-stack JavaScript framework that helps web developers to build – fast, robust, and maintainable enterprise level web applications using – MongoDB, ExpressJS, AngularJS, and Node.js.

It provides web developers the user-friendly full-stack JavaScript framework for building dynamic websites and applications.

Why MEAN stack? and How MEAN stack different from LAMP or WAMP Stack?

MEAN is a collection of various javascript based technologies – Angular, NodeJS, etc. MEAN programming is written in one language, it allows unique server-side and client-side execution environments.

You might have heard about LAMP/WAMP stack development, where a server-side application written in PHP, database queries in MySQL data using SQL and client-side front-end in HTML using Javascript in your client side.

Now, imagine what if you just have to focus on one language? MEAN lets you focus on one programming language throughout your development journey.

Features of MEAN stack

  • One language across web app development
    Since all these technologies are written in JavaScript, your web development process becomes neat and clean
  • Simple and Quick
    Development of websites and applications that revolve in one language, JavaScript, is relatively straightforward.
  • Cost-Effective
    Organizations do not need to hire different specialists to work on a single project, such as PHP developer, Javascript developer, MySQL developer. MEAN stack has also introduced a new career opportunity to full-stack JavaScript developer.
  • Adaptability
    MEAN Stack’s common programming language, JavaScript, it is highly adaptable for a wide range of web applications.
  • JOB Creation
    The requirement of full-stack engineers has increased who are familiar with MEAN Stack and other JavaScript-based technologies.
  • Help & Support
    MEAN has written in JavaScript language which the world-famous active development community.

MEAN Stack Tutorial explains the following components:

MEAN is a simple web development stack for the front end, server-side and back end development logic. MEAN is a free and open-source JavaScript software stack for building dynamic websites and web applications.

The MEAN stack is a combination of MongoDB, Express.js, AngularJS (or Angular), and Node.js. All components of MEAN are JavaScript-based capable of end-to-end web application development.

Essential components of MEAN stack:


  • MongoDB is a Non-relation a NoSQL database server. MongoDB is document-oriented NoSQL database server. It uses JSON like documents with the schema.
  • It provides amazing DB performance even when used to store a large amount of data.


  • Express is a web application development framework that runs over Node.js
  • Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.
  • a web application framework that provides a robust set of features for web and mobile applications. 


  • JavaScript-based MVC frameworks used to development Single Page Applications (SPA).
  • Angular is a JavaScript-based open-source front-end web application development framework.
  • It was developed and maintained by Google.

Angular is also used for developing cross-platform Mobile App’s.


Node.js is the most popular open-source, cross-platform javascript-based run-time environment that executes javascript code outside of the browser.
Traditionally, JavaScript was mainly used for client-side scripting in which javascript code is embedded into HTML web pages.
In this case, the client Javascript code was executed in a web browser before the HTMP page rendered to the user.

  • Node.js is used to run the server-side JavaScript code to handle dynamic web pages. 
  • Node.js also used for the development of web servers and networking tools using JavaScript.
  • Node.js brings event-driven programming to web servers, enabling the development of fast web servers in JavaScript

Applications of MEAN Stack:

  • Web & Software development
  • Real-Time Multi-user Interactivity
  • Development of web servers using Node.js
  • Large Scale Applications with User Connectivity
  • Mobile App Back–End Development

 MEAN stack alternatives:

Some popular alternatives include MERN with React.js, MEVN with Vue.js, or MEN with Vanilla JS.
