What Is MEAN Stack?

MEAN stands for MongoDB, ExpressJS, AngularJS and Node.js. MEAN refers to a cluster of JavaScript-based technologies used to develop unique, quick and robust web applications. From client to server and server to database, MEAN is full stack JavaScript.
The four components of the MEAN stack were developed at different points in time. But, now they are assembled together to form the MEAN stack. It provides a modern approach which simplifies and stimulates web application development.

MongoDB is classified as a NoSQL, schemaless database system. It stores data in JSON format which makes it easier to pass data between client and server. The move from a traditional table-based relational database structure to a NoSQL, such as MongoDB represents JSON-like documents with dynamic schemas. MongoDB is a free and open-source cross-platform document-oriented database.

Express.js is a minimal and flexible web framework to build web applications that runs on Node JS. It still provides an elegant set of features to deal with including single and multi page, hybrid web applications, the RESTful API. Express reduces trouble in setting up a server to handle incoming requests and return relevant response, server side rendering, routing for large-scale applications.

Node.js is a platform built on top of Google Chrome’s V8 engine. It is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code server-side. It helps in building highly scalable and concurrent applications rapidly. It is a framework used to build asynchronous, single threaded I/O applications.

AngularJS is open-source JavaScript framework maintained by Google that assists with single page applications. It is an extremely advanced front-end MVC framework. It’s objective is to build up browser-based applications with Model-View-Controller(MVC) capacity, in an intention to make both development and testing easier.
AngularJS runs uniformly well on desktops and laptops, smartphones and tablets, and even smart TVs. And testing is no longer a second thought with best world-class end-to-end testing frameworks such as KarmaJS and JasmineJS, using these frameworks you can write accurate test suites for your MEAN app.

Why Choose MEAN?

MEAN is a modern and user-friendly full-stack JavaScript framework, which is becoming most popular all over the world for its flexibility and efficiency in web development.
MEAN makes use of the strength of modern and productive single and multi-page applications, which does not need to reload a web page for every single request to the server like the most traditional web applications do. By using a uniform language and form a full-stack solution. MEAN stack is a very simple way to create a responsive, modern and dynamic web applications.
It is open source full-stack solution designed to provide developers with a quick and well-ordered way for creating fast and rapid MEAN-stack based dynamic web applications with excellent performance. This MEAN stack is extremely versatile with JavaScript shining all through the stack. The main reason for choosing the MEAN stack over others is because of the use of a single language throughout the application that is for both client-side and server-side. Since all these technologies are written in JavaScript, the web development process becomes easier to reuse the code from back-end to front-end. MEAN stack is a very efficient and modern approach to web development.
