MEAN Stack and its advantages

MEAN Stack is a collection of JavaScript technologies used to develop web applications. It's a full-stack development toolkit used to develop a fast and robust web application. From the client to the server to the database everything is based on JavaScript. This free and open-source stack offers a quick and organized method for creating rapid prototypes for web-based applications.

MEAN stands for MongoDB, Express.js, AngularJS, and Node.js. It's a user-friendly stack which is the ideal solution for building dynamic websites and applications. The acronym MEAN was coined by Valeri Karpov. He introduced the term in a 2013 blog post.

MEAN comprises four different technologies -

• MongoDB - It's a schemaless NoSQL database system. It's an open-source, cross-platform database which is written in C++. It stores data in the key-value pair, using binary data type like JSON. It is a document-oriented NoSQL Database. A document in MongoDB resembles an Object in OOPS. This an ideal choice for a database system where you need to manage large-sized tables with millions of data.

• Express JS - It's a framework used to build web applications in Node. It's a mature, flexible, lightweight server framework. It's designed for building single, multi-page, and hybrid web applications. This lightweight framework uses the Pug engine to provide support for templates.

• Angular - It's a JavaScript framework developed by Google. It's open-source. The goal of this framework is to introduce MVC(Model View Controller) architecture in the browser-based application that makes the development and testing process easier. The framework helps you create a smarter web app that supports personalization. AngularJS allows us to use HTML as a template language.

• Node.js - It's a server-side JavaScript execution environment. It uses a non-blocking and event-driven I/O model. This makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. It allows developers to create data-intensive real-time apps that run across distributed devices.

How does it work?

• At first, the client makes a request which is processed by the AngularJS.

• Then, the request moves to NodeJS which will parse the request.

• ExpressJs will make calls to MongoDB to get or set data.

• MongoDB will retrieve the requested data and return that request to the Express JS.

• NodeJS will return the request to the client.

• At the client-side, AngularJS to display the result fetched from MongoDB.

Advantages of MEAN Stack

• MEAN stack is that a single language, JavaScript, runs on every level of the application, making it an efficient and modern approach to web development.

• It allows creating a simple open-source solution which can be used to build robust and maintainable solutions.

• It helps in the rapid development of applications.

• MEAN is full-stack JavaScript which is 100% free. Leverage JavaScript's popularity.

• You can use a uniform language throughout your stack.

• It uses very low memory footprint/overhead.

• It helps you to avoid unnecessary groundwork and keeps your application organized.

• MEAN makes code isomorphic.

• MEAN is a user-friendly stack which is the ideal solution for building dynamic websites and applications.

• Mean stack (full stack developer) should work on the Front-end and Back-end.

• Due to the versatility of MEAN Stack’s common programming language, JavaScript, it is highly adaptable for a wide range of web applications.

• MEAN Stack runs on JavaScript, the most common programming language in the world with one of the most active developer communities, making solutions to problems easily accessible.

• MEAN stack applications are flexible, scalable, and extensible, making them the perfect candidate for cloud hosting.

• MEAN is an open-source web stack that is mainly used to create cloud-hosted applications.
