MEAN is a user-friendly stack which is the ideal solution for building dynamic websites and applications. This free and open-source stack offers a quick and organized method for creating rapid prototypes for web-based applications.

MEAN is a full-stack development toolkit used to develop a fast and robust web application.

MEAN is comprised of four different technologies:

  • MongoDB express is a schemaless NoSQL database system.
  • Express JS is a framework used to build web applications in Node
  • AngularJS is a JavaScript framework developed by Google
  • Node.js is a server-side JavaScript execution environment
Advantages of Mean Stack
  • Allows creating a simple open source solution which can be used to build robust and maintainable solutions.
  • Helps in rapid development of applications.
  • MEAN is full stack JavaScript which is 100% free. Leverage JavaScript's popularity.
  • Use a uniform language throughout your stack.
  • Uses very low memory footprint/overhead.
  • Helps you to avoid unnecessary groundwork and keeps your application organized.
  • MongoDB is built for the cloud.
  • Node.js simplifies the server layer.
  • MEAN makes code isomorphic.

MongoDB is 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.

Express is a mature, flexible, lightweight server framework. It is designed for building single, multi-page, and hybrid web applications. This lightweight framework uses the Pug engine to provide support for templates.

Angular JS is an open-source JavaScript framework. Angular is maintained by Google. 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.

Node.js 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.
