The MEAN stack is growing in popularity. Valued for its flexibility, consistent language, and scalability, the MEAN stack is an excellent choice for any web development destined for the cloud. MEAN is an acronym for MongoDB, ExpressJS, AngularJS and Node.js. From client to server to database, MEAN is full stack JavaScript. A MEAN stack developer is someone who is has knowledge in some particular areas alone. Express is lightweight framework used to build web applications in Node.

It uses object-oriented organization instead of a relational model. In the MEAN stack, MongoDB stores the application's data. Because both the application and the database use JavaScript, there's no need to translate the object as it journeys from the application to the database and back. MEAN is an open source web stack that is mainly used to create cloud-hosted applications. MEAN stack applications are flexible, scalable, and extensible, making them the perfect candidate for cloud hosting. The stack includes its own web server so it can be deployed easily, and the database can be scaled on demand to accommodate temporary usage spikes. A MEAN application enters the world optimized to take advantage of all the cost savings and performance improvements of the cloud.

What is Mean Stack?

Mean stack refers to a collection of JavaScript technologies used to develop web applications. Therefore, from the client to the server to the database everything is based on JavaScript. MEAN is a full-stack development toolkit used to develop a fast and robust web application.
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 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
AngularJSis a JavaScript framework developed by Google
Node.js is a server-side JavaScript execution environment
