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.
