What is a MEAN Stack?

MEAN is a JavaScript development stack that helps you build fast, robust, and maintainable production web applications using MongoDB, Express, AngularJS, and NodeJS. 

MEAN stack back-end with MongoDB, ExpressJS and NodeJS.
MEAN stack front-end with AngularJS.

Why do I care?

    ➤Write one language. 
    ➤With MongoDB and Mongoose, easy and flexible data validation.
    ➤With NodeJS, never need threads. 
    ➤With AngularJS, dynamic client-side templates.

Same Language, Same Objects

MEAN Stack Structure

More Information

MongoDB is the leading NoSQL database, empowering businesses to be more agile and scalable. It’s designed for storing non-relational data. It’s included in the stack because it’s queried using JSON and can persist objects as serialized JSON, making it ideal for JavaScript clients. It’s fast, open-source, flexible and cross-platform document-oriented database, suited for simpler applications.

Express is a lightweight Node.js web application framework. Node provides a http module by default but it’s very low level. Express wraps this up to provide simple get/post methods and other routing. In the stack, it glues everything together, and it’s also written in JavaScript. It's providing a robust set of features for building single and multi-page, and hybrid web applications.

AngularJS  is a front end JavaScript framework developed by Google, UI and client side logic of the stack. The application’s structure is defined in HTML and extended by AngularJS directives. Control logic is nicely separated into Controllers which are easy to re-use and organize. Angular brings a lot to bear in reducing complexity but at the cost of less control. It provides comprehensive features such as the two-way data binding, routing, DI of services.  It's a complete solution for rapids and awesome front end development.

Node JS is a platform built on Chrome's V8 JavaScript engine runtime for easily building fast, scalable network applications. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node is useful as it allows the server to push to the client over web sockets, helping to create responsive web applications. It was included in the stack to as it provides the server-side processing and it’s applications are written in JavaScript. It also brings npm, a package popular package manager, to the party.
