MEAN Stack In a Nutshell!

Talking about MERN Stack VS MEAN Stack, MEAN Stack is one of the most adopted web development technologies these days. It has many components, likewise MongoDB, Express.JS, Angular, and Node.JS. MEAN empowers the development of full-stack web applications which use JavaScript in the entire application stack.

MEAN Stack Components Overview

MongoDB (M):

A scalable NoSQL database storing data in JSON-like format, ideal for managing vast data volumes efficiently.

Express.js (E):

A lightweight web framework for Node.js, simplifying backend development with routing and middleware support for HTTP requests.

Angular (A):

Google-developed frontend framework enabling dynamic user interfaces through component-based architecture and two-way data binding.

Node.js (N):

A server-side JavaScript runtime facilitating scalable and high-performance backend development, complementing Express.js in MEAN stack applications.

How MEAN Architecture Functions?

The MEAN architecture seamlessly integrates its four core components—MongoDB, Express.js, Angular, and Node.js—to facilitate full-stack web application development.

Client-Side (Angular):

Angular manages the front end, empowering developers to craft dynamic user interfaces. With its component-based architecture and support for two-way data binding, Angular streamlines UI development, ensuring efficiency and interactivity.

Server-Side (Node.js and Express.js):

Node.js, in tandem with the Express.js framework, drives the backend of the application. Express simplifies backend development by handling routing, middleware, and HTTP requests. Node.js executes server-side JavaScript, ensuring scalability and high performance.

Database (MongoDB):

MongoDB, a NoSQL database, stores and retrieves data in a flexible JSON-like format. Integrated seamlessly with the Node.js backend, MongoDB facilitates efficient data handling and retrieval.

Communication:

Angular communicates with the Node.js backend through API calls. Express.js processes these requests, interacts with the MongoDB database as needed, and returns the data to the Angular frontend. This architecture ensures smooth data flow and operations, enabling developers to construct modern and scalable web applications.

What are the Pros & Cons of MEAN Stack?

Here are the following pros, and Cons of MEAN Stack that helps you out to choose it or not for applications development. Let’s discuss the pros, and cons in the following:
