An Introduction to the MEAN Stack

The term MEAN stack refers to a collection of JavaScript based technologies used to develop web applications. MEAN is a set of Open Source components that together, provide an end-to-end framework for building dynamic web applications.

• MongoDB : Document database – used by your back-end application to store its data as JSON (JavaScript Object Notation) documents.
  
• MongoDB is a document database with the scalability and flexibility that you want with the querying and indexing that you need.
  
  
• Express (sometimes referred to as Express.js): Back-end web application framework running on top of Node.js .
  
• Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.
  
  
• Angular (formerly Angular.js): Front-end web app framework; runs your JavaScript code in the user’s browser, allowing your application UI to be dynamic
  
• Angular is a platform that makes it easy to build applications with the web. Angular combines declarative templates, dependency injection, end to end tooling, and integrated best practices to solve development challenges. Angular empowers developers to build applications that live on the web, mobile, or the desktop.
  
  
• Node.js : JavaScript runtime environment – lets you implement your application back-end in JavaScript
  
• Node.js is a server side JavaScript execution environment. It’s a platform built on Google Chrome’s V8 JavaScript runtime. It helps in building highly scalable and concurrent applications rapidly.

WHY LEARN MEAN?

It’s hard to accomplish much on the web without JavaScript, which is the single language that runs the entire MEAN full stack and boasts one of the most active developer communities. Because every part of MEAN programming is written in one language, it allows unique server-side and client-side execution environments. Valued for its versatility in building fast, robust and maintainable production web applications, MEAN is in high demand with numerous startups and employers.
